 本仓库自 **v1.0.0** 起作为正式版维护；此前历史提交已归档重置。
 ## [Unreleased]
 ## [1.2.6] - 2026-09-01
 ### 新增
 - 设置、API、图库、存储页 UI 重构（侧栏导航、统计卡片、在线调试等）
 - 图库筛选增加存储后端下拉
 - 新建对象存储后端按类型生成存储标识：`r2-*`、`cos-*`、`oss-*`、`s3-*`
 ### 改进
 - 操作日志表格：操作/来源标签同行展示，路径列省略号截断、无横向滚动条
 - 存储后端卡片：存储标识与类型同一行左对齐排列
 - README 与文档站截图、导航说明同步新界面
 ## [1.2.5] - 2026-08-31
 ### 新增
 - 图库页（`/gallery`）替代原「统计」导航；图片点击放大详情弹层（尺寸、上传方式、存储路径、链接复制）
 - 图库列表支持全选、反选；单张删除移至详情弹层
 - 图片列表 API 返回上传来源（网页 / API，来自活动日志）
 ### 改进
 - README 补充技术栈说明
 ### 移除
 - `/stats` 路由（不再兼容跳转）
 ## [1.2.4] - 2026-08-31
 ### 修复
 - 访问控制（Referer 防盗链）留空时仍会拦截外链图片：浏览器直开无 Referer 可访问，博客/论坛嵌入带 Referer 会 403 图裂；现仅在配置了白名单时才校验
 ## [1.2.3] - 2026-08-30
 ### 修复
 - 开启「简短图片链接」且按年/月分组时，纯文件名直链（如 `/xxx.webp`）误解析为 `images/xxx.webp` 导致 404；现先经 SQLite 索引反查完整 key
 ## [1.2.2] - 2026-08-30
 ### 修复
 - 双域名：设置页保存时误清空管理域（`site_base_url`）；仅改图片域时保护已有网站域配置
 - 双域名：设置 API 配置值与 request origin fallback 混淆，导致「当前生效」显示错误
 - 双域名：未配置的第三 Host（`pages.dev`、裸 IP 等）可绕过 Host 隔离访问后台
 ### 改进
 - 设置 API 拆分 `siteBaseUrl` / `imageBaseUrl`（配置值）、`effective*`（直链）、`runtime`（当前访问检测）
 - `PATCH /api/settings` 增加 `domainSeparation` 字段与保存校验
 - 设置页：检测地址展示、关闭双域名确认、反代 Host 不一致警告；首次设置不再自动填入 origin
 - Host 中间件：双域名开启时对未知 Host 返回 404（开发 `localhost` 例外）
 - 文档站：新增 [更新日志](https://o96u.github.io/PicHost/guide/changelog)；重写 Cloudflare 部署说明；同步 FAQ / 双域名文档
 ## [1.2.1] - 2026-08-29
 ### 新增
 - 登录滑动拼图验证（缺口对齐）；验证与登录分两步，登录接口校验 `captchaId` / `captchaPosition`
 - VitePress 文档站（`docs-site/`）：中英文指南，部署至 GitHub Pages <https://o96u.github.io/PicHost/>
 - `npm run docs:dev` / `docs:build` / `docs:preview`；CI 增加 `docs:build`；`.github/workflows/docs.yml` 发布文档
 ### 修复
 - 修复统计页删除图片后图库不刷新的问题
 - 修复分页跳转输入框在 `type="number"` 下无法跳转的问题
 - 修复非首页路由下复制链接格式偏好不持久化的问题（`useUploadPreferences` 首次使用时自动加载）
 - 滑动验证 UI：滑块垂直居中、缺口尺寸与滑块一致
 ### 改进
 - README 精简为产品宣传页，详细说明指向文档站
 - 双域名文档补充：未知 Host 风险、Cloudflare 橙云部署、勿用 Pages/Workers 整站反代
 - 文档截图更新（登录页等）；旧 `docs/*.md` 长文迁入 `docs-site/`
 ## [1.2.0] - 2026-08-28
 ### 变更
 - 图片统一存放在 `data/images/`；遗留 `blog/`、`twikoo/` 等并列目录需迁移后升级
 ### 新增
 - CLI 迁移工具：`docker exec pichost migrate` / `migrate --apply`（`server/cli/migrate-to-single-images.mjs`）
 - 扫描 `data/` 下除 `images` 外所有顶层目录中的图片，输出 `data/mapping.json`
 - 启动时自动同步图片索引（扫描磁盘、归一化遗留 key、清理孤儿记录），并打印同步日志
 - 迁移文档：[文档站 · v1.2 迁移](https://o96u.github.io/PicHost/guide/migration)
 ### 改进
 - 启动时归一化遗留 SQLite key、清理无文件的孤儿索引；支持删除仅索引无文件的记录
 ## [1.1.5] - 2026-08-28
 ### 修复
 - 修复 API 上传后图库预览偶发失败、需等待刷新才显示的问题
 - 图库卡片加载失败后自动重试，刷新列表时重置预览状态
 ### 改进
 - 出图前校验存储文件实际存在，避免索引与磁盘短暂不一致
 - 图片 404/403 与域名隔离 404 禁止 CDN 缓存，降低反代误判影响
 ## [1.1.4] - 2026-08-28
 ### 新增
 - 上传目录可按年/月分组或扁平保存（`storage_use_date_path` / `STORAGE_USE_DATE_PATH`），设置页可切换
 - 双域名分离下网站域禁止直链出图，仅图片域可访问图片路径
 ### 改进
 - 隐藏 `images/` 前缀时外链改为仅文件名（如 `xxx.webp`）；图片域仍兼容旧版 `/2026/08/xxx.webp` 短链
 - 设置页重构：功能开关、域名配置、存储路径分组展示
 - 本地磁盘索引扫描支持扁平路径；文件夹列表 `images` 置顶
 ## [1.1.3] - 2026-08-27
 ### 新增
 - 后台与图片域名分离（`SITE_BASE_URL` / `IMAGE_BASE_URL`）：单实例双域名，Host 中间件隔离图片域非图片路径
 - `/setup` 与系统设置支持启用/关闭域名分离，设置页可后续关闭并恢复单域
 - 可选隐藏外链中的 `images/` 前缀（多文件夹时确认提示）
 - 设置页加载时检测 GitHub 最新版本并提示更新
 - 双域名部署文档（Nginx / Lucky / 本地 hosts 测试）：[文档站 · 双域名分离](https://o96u.github.io/PicHost/guide/domain-separation)
 ### 改进
 - 双域名下防盗链自动放行网站域与图片域主机名
 - 开发服务器默认绑定 `127.0.0.1:3000`，便于 hosts 双域本地测试
 - API 文档补充自定义文件夹的 cURL 示例
 ### 其他
 - 许可证变更为 GPL-3.0-only
 - `scripts/` 目录改为本地维护，不再纳入仓库
 ## [1.1.2] - 2026-08-26
 ### 新增
 - 操作日志页（`/logs`）：记录上传/删除，管理员可查看全部用户并筛选
 - 图库记录支持按存储后端筛选
 - 上传 IP / API Token 限流（15 分钟窗口）
 ### 改进
 - 操作日志记录存储后端；图库卡片可展示存储来源
 - 存储筛选下拉固定「本地磁盘」排在第二位
 - 系统设置页版本号链接至 GitHub Releases
 ### 修复
 - 修复删除存储后端后确认弹窗闪出空名称
 ## [1.1.1] - 2026-08-26
 ### 修复
 - 移除启动时自动创建的空白「S3 兼容存储」占位；升级后自动清理旧占位记录
 - 修复管理页切换路由时反复闪现「正在验证登录状态」
 - 修复静默会话校验后设置 / 统计 / API 页不加载数据
 ### 改进
 - Docker 日志：4xx/5xx 分级输出，记录错误原因与堆栈；上传/启动任务失败写入详细错误
 ## [1.1.0] - 2026-08-26
 ### 新增
 - S3 兼容对象存储后端（R2 / AWS S3 / 腾讯云 COS / 阿里云 OSS）

 ### 改进
 - 启动时自动将本地磁盘图片扫描迁入 `images` 索引（幂等）
 - 上传/删除/直链/auto-delete 按 `backend_id` 路由到对应后端
 ## [1.0.4] - 2026-08-25
 ### 新增
 - 密码输入框支持显示/隐藏切换（`PasswordInput` 组件，含无障碍文案）
 ### 改进
 - 遗留 `ADMIN_SECRET` 部署：`/setup`、`/register` 路由与 `needsMigration` 检测对齐

+share and change all versions of a program--to make sure it remains free
 software for all its users.  We, the Free Software Foundation, use the
 GNU General Public License for most of our software; it applies also to
 any other work released this way by its authors.  You can apply it to
 your programs, too.
  When we speak of free software, we are referring to freedom, not
 price.  Our General Public Licenses are designed to make sure that you
 have the freedom to distribute copies of free software (and charge for
 them if you wish), that you receive source code or can get it if you
 want it, that you can change the software or use pieces of it in new
 free programs, and that you know you can do these things.
  To protect your rights, we need to prevent others from denying you
 these rights or asking you to surrender the rights.  Therefore, you have
 certain responsibilities if you distribute copies of the software, or if
 you modify it: responsibilities to respect the freedom of others.
  For example, if you distribute copies of such a program, whether
 gratis or for a fee, you must pass on to the recipients the same
 freedoms that you received.  You must make sure that they, too, receive
 or can get the source code.  And you must show them these terms so they
 know their rights.
  Developers that use the GNU GPL protect your rights with two steps:
 (1) assert copyright on the software, and (2) offer you this License
 giving you legal permission to copy, distribute and/or modify it.
  For the developers' and authors' protection, the GPL clearly explains
 that there is no warranty for this free software.  For both users' and
 authors' sake, the GPL requires that modified versions be marked as
 changed, so that their problems will not be attributed erroneously to
 authors of previous versions.
  Some devices are designed to deny users access to install or run
 modified versions of the software inside them, although the manufacturer
 can do so.  This is fundamentally incompatible with the aim of
 protecting users' freedom to change the software.  The systematic
 pattern of such abuse occurs in the area of products for individuals to
 use, which is precisely where it is most unacceptable.  Therefore, we
 have designed this version of the GPL to prohibit the practice for those
 products.  If such problems arise substantially in other domains, we
 stand ready to extend this provision to those domains in future versions
 of the GPL, as needed to protect the freedom of users.
  Finally, every program is threatened constantly by software patents.
 States should not allow patents to restrict development and use of
 software on general-purpose computers, but in those that do, we wish to
 avoid the special danger that patents applied to a free program could
 make it effectively proprietary.  To prevent this, the GPL assures that
 patents cannot be used to render the program non-free.
  The precise terms and conditions for copying, distribution and
 modification follow.

 in a fashion requiring copyright permission, other than the making of an
 exact copy.  The resulting work is called a "modified version" of the
 earlier work or a work "based on" the earlier work.
  A "covered work" means either the unmodified Program or a work based
 on the Program.
  To "propagate" a work means to do anything with it that, without
 permission, would make you directly or secondarily liable for
 infringement under applicable copyright law, except executing it on a
 computer or modifying a private copy.  Propagation includes copying,
 distribution (with or without modification), making available to the
 public, and in some countries other activities as well.
  To "convey" a work means any kind of propagation that enables other
 parties to make or receive copies.  Mere interaction with a user through
 a computer network, with no transfer of a copy, is not conveying.
  An interactive user interface displays "Appropriate Legal Notices"
 to the extent that it includes a convenient and prominently visible
 feature that (1) displays an appropriate copyright notice, and (2)
 tells the user that there is no warranty for the work (except to the
 extent that warranties are provided), that licensees may convey the
 work under this License, and how to view a copy of this License.  If
 the interface presents a list of user commands or options, such as a
 menu, a prominent item in the list meets this criterion.
  1. Source Code.
  The "source code" for a work means the preferred form of the work
 for making modifications to it.  "Object code" means any non-source
 form of a work.
  A "Standard Interface" means an interface that either is an official
 standard defined by a recognized standards body, or, in the case of
 interfaces specified for a particular programming language, one that
 is widely used among developers working in that language.
  The "System Libraries" of an executable work include anything, other
 than the work as a whole, that (a) is included in the normal form of
 packaging a Major Component, but which is not part of that Major
 Component, and (b) serves only to enable use of the work with that
 Major Component, or to implement a Standard Interface for which an
 implementation is available to the public in source code form.  A
 "Major Component", in this context, means a major essential component
 (kernel, window system, and so on) of the specific operating system
 (if any) on which the executable work runs, or a compiler used to
 produce the work, or an object code interpreter used to run it.
  The "Corresponding Source" for a work in object code form means all
 the source code needed to generate, install, and (for an executable
 work) run the object code and to modify the work, including scripts to
 control those activities.  However, it does not include the work's
 System Libraries, or general-purpose tools or generally available free
 programs which are used unmodified in performing those activities but
 which are not part of the work.  For example, Corresponding Source
 includes interface definition files associated with source files for
 the work, and the source code for shared libraries and dynamically
 linked subprograms that the work is specifically designed to require,
 such as by intimate data communication or control flow between those
 subprograms and other parts of the work.
  The Corresponding Source need not include anything that users
 can regenerate automatically from other parts of the Corresponding
 Source.
  The Corresponding Source for a work in source code form is that
 same work.
  2. Basic Permissions.
  All rights granted under this License are granted for the term of
 copyright on the Program, and are irrevocable provided the stated
 conditions are met.  This License explicitly affirms your unlimited
 permission to run the unmodified Program.  The output from running a
 covered work is covered by this License only if the output, given its
 content, constitutes a covered work.  This License acknowledges your
 rights of fair use or other equivalent, as provided by copyright law.
  You may make, run and propagate covered works that you do not
 convey, without conditions so long as your license otherwise remains
 in force.  You may convey covered works to others for the sole purpose
 of having them make modifications exclusively for you, or provide you
 with facilities for running those works, provided that you comply with
 the terms of this License in conveying all material for which you do
 not control copyright.  Those thus making or running the covered works
 for you must do so exclusively on your behalf, under your direction
 and control, on terms that prohibit them from making any copies of
 your copyrighted material outside their relationship with you.
  Conveying under any other circumstances is permitted solely under
 the conditions stated below.  Sublicensing is not allowed; section 10
 makes it unnecessary.
  3. Protecting Users' Legal Rights From Anti-Circumvention Law.
  No covered work shall be deemed part of an effective technological
 measure under any applicable law fulfilling obligations under article
 11 of the WIPO copyright treaty adopted on 20 December 1996, or
 similar laws prohibiting or restricting circumvention of such
 measures.
  When you convey a covered work, you waive any legal power to forbid
 circumvention of technological measures to the extent such circumvention
 is effected by exercising rights under this License with respect to
 the covered work, and you disclaim any intention to limit operation or
 modification of the work as a means of enforcing, against the work's
 users, your or third parties' legal rights to forbid circumvention of
 technological measures.
  4. Conveying Verbatim Copies.
  You may convey verbatim copies of the Program's source code as you
 receive it, in any medium, provided that you conspicuously and
 appropriately publish on each copy an appropriate copyright notice;
 keep intact all notices stating that this License and any
 non-permissive terms added in accord with section 7 apply to the code;
 keep intact all notices of the absence of any warranty; and give all
 recipients a copy of this License along with the Program.
  You may charge any price or no price for each copy that you convey,
 and you may offer support or warranty protection for a fee.
  5. Conveying Modified Source Versions.
  You may convey a work based on the Program, or the modifications to
 produce it from the Program, in the form of source code under the
 terms of section 4, provided that you also meet all of these conditions:
    a) The work must carry prominent notices stating that you modified
    it, and giving a relevant date.
    b) The work must carry prominent notices stating that it is
    released under this License and any conditions added under section
    7.  This requirement modifies the requirement in section 4 to
    "keep intact all notices".
    c) You must license the entire work, as a whole, under this
    License to anyone who comes into possession of a copy.  This
    License will therefore apply, along with any applicable section 7
    additional terms, to the whole of the work, and all its parts,
    regardless of how they are packaged.  This License gives no
    permission to license the work in any other way, but it does not
    invalidate such permission if you have separately received it.
    d) If the work has interactive user interfaces, each must display
    Appropriate Legal Notices; however, if the Program has interactive
    interfaces that do not display Appropriate Legal Notices, your
    work need not make them do so.
  A compilation of a covered work with other separate and independent
 works, which are not by their nature extensions of the covered work,
 and which are not combined with it such as to form a larger program,
 in or on a volume of a storage or distribution medium, is called an
 "aggregate" if the compilation and its resulting copyright are not
 used to limit the access or legal rights of the compilation's users
 beyond what the individual works permit.  Inclusion of a covered work
 in an aggregate does not cause this License to apply to the other
 parts of the aggregate.
  6. Conveying Non-Source Forms.
  You may convey a covered work in object code form under the terms
 of sections 4 and 5, provided that you also convey the
 machine-readable Corresponding Source under the terms of this License,
 in one of these ways:
    a) Convey the object code in, or embodied in, a physical product
    (including a physical distribution medium), accompanied by the
    Corresponding Source fixed on a durable physical medium
    customarily used for software interchange.
    b) Convey the object code in, or embodied in, a physical product
    (including a physical distribution medium), accompanied by a
    written offer, valid for at least three years and valid for as
    long as you offer spare parts or customer support for that product
    model, to give anyone who possesses the object code either (1) a
    copy of the Corresponding Source for all the software in the
    product that is covered by this License, on a durable physical
    medium customarily used for software interchange, for a price no
    more than your reasonable cost of physically performing this
    conveying of source, or (2) access to copy the
    Corresponding Source from a network server at no charge.
    c) Convey individual copies of the object code with a copy of the
    written offer to provide the Corresponding Source.  This
    alternative is allowed only occasionally and noncommercially, and
    only if you received the object code with such an offer, in accord
    with subsection 6b.
    d) Convey the object code by offering access from a designated
    place (gratis or for a charge), and offer equivalent access to the
    Corresponding Source in the same way through the same place at no
    further charge.  You need not require recipients to copy the
    Corresponding Source along with the object code.  If the place to
    copy the object code is a network server, the Corresponding Source
    may be on a different server (operated by you or a third party)
    that supports equivalent copying facilities, provided you maintain
    clear directions next to the object code saying where to find the
    Corresponding Source.  Regardless of what server hosts the
    Corresponding Source, you remain obligated to ensure that it is
    available for as long as needed to satisfy these requirements.
    e) Convey the object code using peer-to-peer transmission, provided
    you inform other peers where the object code and Corresponding
    Source of the work are being offered to the general public at no
    charge under subsection 6d.
  A separable portion of the object code, whose source code is excluded
 from the Corresponding Source as a System Library, need not be
 included in conveying the object code work.
  A "User Product" is either (1) a "consumer product", which means any
 tangible personal property which is normally used for personal, family,
 or household purposes, or (2) anything designed or sold for incorporation
 into a dwelling.  In determining whether a product is a consumer product,
 doubtful cases shall be resolved in favor of coverage.  For a particular
 product received by a particular user, "normally used" refers to a
 typical or common use of that class of product, regardless of the status
 of the particular user or of the way in which the particular user
 actually uses, or expects or is expected to use, the product.  A product
 is a consumer product regardless of whether the product has substantial
 commercial, industrial or non-consumer uses, unless such uses represent
 the only significant mode of use of the product.
  "Installation Information" for a User Product means any methods,
 procedures, authorization keys, or other information required to install
 and execute modified versions of a covered work in that User Product from
 a modified version of its Corresponding Source.  The information must
 suffice to ensure that the continued functioning of the modified object
 code is in no case prevented or interfered with solely because
 modification has been made.
  If you convey an object code work under this section in, or with, or
 specifically for use in, a User Product, and the conveying occurs as
 part of a transaction in which the right of possession and use of the
 User Product is transferred to the recipient in perpetuity or for a
 fixed term (regardless of how the transaction is characterized), the
 Corresponding Source conveyed under this section must be accompanied
 by the Installation Information.  But this requirement does not apply
 if neither you nor any third party retains the ability to install
 modified object code on the User Product (for example, the work has
 been installed in ROM).
  The requirement to provide Installation Information does not include a
 requirement to continue to provide support service, warranty, or updates
 for a work that has been modified or installed by the recipient, or for
 the User Product in which it has been modified or installed.  Access to a
 network may be denied when the modification itself materially and
 adversely affects the operation of the network or violates the rules and
 protocols for communication across the network.
  Corresponding Source conveyed, and Installation Information provided,
 in accord with this section must be in a format that is publicly
 documented (and with an implementation available to the public in
 source code form), and must require no special password or key for
 unpacking, reading or copying.
  7. Additional Terms.
  "Additional permissions" are terms that supplement the terms of this
 License by making exceptions from one or more of its conditions.
 Additional permissions that are applicable to the entire Program shall
 be treated as though they were included in this License, to the extent
 that they are valid under applicable law.  If additional permissions
 apply only to part of the Program, that part may be used separately
 under those permissions, but the entire Program remains governed by
 this License without regard to the additional permissions.
  When you convey a copy of a covered work, you may at your option
 remove any additional permissions from that copy, or from any part of
 it.  (Additional permissions may be written to require their own
 removal in certain cases when you modify the work.)  You may place
 additional permissions on material, added by you to a covered work,
 for which you have or can give appropriate copyright permission.
  Notwithstanding any other provision of this License, for material you
 add to a covered work, you may (if authorized by the copyright holders of
 that material) supplement the terms of this License with terms:
    a) Disclaiming warranty or limiting liability differently from the
    terms of sections 15 and 16 of this License; or
    b) Requiring preservation of specified reasonable legal notices or
    author attributions in that material or in the Appropriate Legal
    Notices displayed by works containing it; or
    c) Prohibiting misrepresentation of the origin of that material, or
    requiring that modified versions of such material be marked in
    reasonable ways as different from the original version; or
    d) Limiting the use for publicity purposes of names of licensors or
    authors of the material; or
    e) Declining to grant rights under trademark law for use of some
    trade names, trademarks, or service marks; or
    f) Requiring indemnification of licensors and authors of that
    material by anyone who conveys the material (or modified versions of
    it) with contractual assumptions of liability to the recipient, for
    any liability that these contractual assumptions directly impose on
    those licensors and authors.
  All other non-permissive additional terms are considered "further
 restrictions" within the meaning of section 10.  If the Program as you
 received it, or any part of it, contains a notice stating that it is
 governed by this License along with a term that is a further
 restriction, you may remove that term.  If a license document contains
 a further restriction but permits relicensing or conveying under this
 License, you may add to a covered work material governed by the terms
 of that license document, provided that the further restriction does
 not survive such relicensing or conveying.
  If you add terms to a covered work in accord with this section, you
 must place, in the relevant source files, a statement of the
 additional terms that apply to those files, or a notice indicating
 where to find the applicable terms.
  Additional terms, permissive or non-permissive, may be stated in the
 form of a separately written license, or stated as exceptions;
 the above requirements apply either way.
  8. Termination.
  You may not propagate or modify a covered work except as expressly
 provided under this License.  Any attempt otherwise to propagate or
 modify it is void, and will automatically terminate your rights under
 this License (including any patent licenses granted under the third
 paragraph of section 11).
  However, if you cease all violation of this License, then your
 license from a particular copyright holder is reinstated (a)
 provisionally, unless and until the copyright holder explicitly and
 finally terminates your license, and (b) permanently, if the copyright
 holder fails to notify you of the violation by some reasonable means
 prior to 60 days after the cessation.
  Moreover, your license from a particular copyright holder is
 reinstated permanently if the copyright holder notifies you of the
 violation by some reasonable means, this is the first time you have
 received notice of violation of this License (for any work) from that
 copyright holder, and you cure the violation prior to 30 days after
 your receipt of the notice.
  Termination of your rights under this section does not terminate the
 licenses of parties who have received copies or rights from you under
 this License.  If your rights have been terminated and not permanently
 reinstated, you do not qualify to receive new licenses for the same
 material under section 10.
  9. Acceptance Not Required for Having Copies.
  You are not required to accept this License in order to receive or
 run a copy of the Program.  Ancillary propagation of a covered work
 occurring solely as a consequence of using peer-to-peer transmission
 to receive a copy likewise does not require acceptance.  However,
 nothing other than this License grants you permission to propagate or
 modify any covered work.  These actions infringe copyright if you do
 not accept this License.  Therefore, by modifying or propagating a
 covered work, you indicate your acceptance of this License to do so.
  10. Automatic Licensing of Downstream Recipients.
  Each time you convey a covered work, the recipient automatically
 receives a license from the original licensors, to run, modify and
 propagate that work, subject to this License.  You are not responsible
 for enforcing compliance by third parties with this License.
  An "entity transaction" is a transaction transferring control of an
 organization, or substantially all assets of one, or subdividing an
 organization, or merging organizations.  If propagation of a covered
 work results from an entity transaction, each party to that
 transaction who receives a copy of the work also receives whatever
 licenses to the work the party's predecessor in interest had or could
 give under the previous paragraph, plus a right to possession of the
 Corresponding Source of the work from the predecessor in interest, if
 the predecessor has it or can get it with reasonable efforts.
  You may not impose any further restrictions on the exercise of the
 rights granted or affirmed under this License.  For example, you may
 not impose a license fee, royalty, or other charge for exercise of
 rights granted under this License, and you may not initiate litigation
 (including a cross-claim or counterclaim in a lawsuit) alleging that
 any patent claim is infringed by making, using, selling, offering for
 sale, or importing the Program or any portion of it.
  11. Patents.
  A "contributor" is a copyright holder who authorizes use under this
 License of the Program or a work on which the Program is based.  The
 work thus licensed is called the contributor's "contributor version".
  A contributor's "essential patent claims" are all patent claims
 owned or controlled by the contributor, whether already acquired or
 hereafter acquired, that would be infringed by some manner, permitted
 by this License, of making, using, or selling its contributor version,
 but do not include claims that would be infringed only as a
 consequence of further modification of the contributor version.  For
 purposes of this definition, "control" includes the right to grant
 patent sublicenses in a manner consistent with the requirements of
 this License.
  Each contributor grants you a non-exclusive, worldwide, royalty-free
 patent license under the contributor's essential patent claims, to
 make, use, sell, offer for sale, import and otherwise run, modify and
 propagate the contents of its contributor version.
  In the following three paragraphs, a "patent license" is any express
 agreement or commitment, however denominated, not to enforce a patent
 (such as an express permission to practice a patent or covenant not to
 sue for patent infringement).  To "grant" such a patent license to a
 party means to make such an agreement or commitment not to enforce a
 patent against the party.
  If you convey a covered work, knowingly relying on a patent license,
 and the Corresponding Source of the work is not available for anyone
 to copy, free of charge and under the terms of this License, through a
 publicly available network server or other readily accessible means,
 then you must either (1) cause the Corresponding Source to be so
 available, or (2) arrange to deprive yourself of the benefit of the
 patent license for this particular work, or (3) arrange, in a manner
 consistent with the requirements of this License, to extend the patent
 license to downstream recipients.  "Knowingly relying" means you have
 actual knowledge that, but for the patent license, your conveying the
 covered work in a country, or your recipient's use of the covered work
 in a country, would infringe one or more identifiable patents in that
 country that you have reason to believe are valid.
  If, pursuant to or in connection with a single transaction or
 arrangement, you convey, or propagate by procuring conveyance of, a
 covered work, and grant a patent license to some of the parties
 receiving the covered work authorizing them to use, propagate, modify
 or convey a specific copy of the covered work, then the patent license
 you grant is automatically extended to all recipients of the covered
 work and works based on it.
  A patent license is "discriminatory" if it does not include within
 the scope of its coverage, prohibits the exercise of, or is
 conditioned on the non-exercise of one or more of the rights that are
 specifically granted under this License.  You may not convey a covered
 work if you are a party to an arrangement with a third party that is
 in the business of distributing software, under which you make payment
 to the third party based on the extent of your activity of conveying
 the work, and under which the third party grants, to any of the
 parties who would receive the covered work from you, a discriminatory
 patent license (a) in connection with copies of the covered work
 conveyed by you (or copies made from those copies), or (b) primarily
 for and in connection with specific products or compilations that
 contain the covered work, unless you entered into that arrangement,
 or that patent license was granted, prior to 28 March 2007.
  Nothing in this License shall be construed as excluding or limiting
 any implied license or other defenses to infringement that may
 otherwise be available to you under applicable patent law.
  12. No Surrender of Others' Freedom.
  If conditions are imposed on you (whether by court order, agreement or
 otherwise) that contradict the conditions of this License, they do not
 excuse you from the conditions of this License.  If you cannot convey a
 covered work so as to satisfy simultaneously your obligations under this
 License and any other pertinent obligations, then as a consequence you may
 not convey it at all.  For example, if you agree to terms that obligate you
 to collect a royalty for further conveying from those to whom you convey
 the Program, the only way you could satisfy both those terms and this
 License would be to refrain entirely from conveying the Program.
  13. Use with the GNU Affero General Public License.
  Notwithstanding any other provision of this License, you have
 permission to link or combine any covered work with a work licensed
 under version 3 of the GNU Affero General Public License into a single
 combined work, and to convey the resulting work.  The terms of this
 License will continue to apply to the part which is the covered work,
 but the special requirements of the GNU Affero General Public License,
 section 13, concerning interaction through a network will apply to the
 combination as such.
  14. Revised Versions of this License.
  The Free Software Foundation may publish revised and/or new versions of
 the GNU General Public License from time to time.  Such new versions will
 be similar in spirit to the present version, but may differ in detail to
 address new problems or concerns.
  Each version is given a distinguishing version number.  If the
 Program specifies that a certain numbered version of the GNU General
 Public License "or any later version" applies to it, you have the
 option of following the terms and conditions either of that numbered
 version or of any later version published by the Free Software
 Foundation.  If the Program does not specify a version number of the
 GNU General Public License, you may choose any version ever published
 by the Free Software Foundation.
  If the Program specifies that a proxy can decide which future
 versions of the GNU General Public License can be used, that proxy's
 public statement of acceptance of a version permanently authorizes you
 to choose that version for the Program.
  Later license versions may give you additional or different
 permissions.  However, no additional obligations are imposed on any
 author or copyright holder as a result of your choosing to follow a
 later version.
  15. Disclaimer of Warranty.
  THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
 APPLICABLE LAW.  EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
 HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
 OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
 THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
 PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
 IS WITH YOU.  SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
 ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
  16. Limitation of Liability.
  IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
 WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
 THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
 GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
 USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
 DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
 PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
 EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
 SUCH DAMAGES.
  17. Interpretation of Sections 15 and 16.
  If the disclaimer of warranty and limitation of liability provided
 above cannot be given local legal effect according to their terms,
 reviewing courts shall apply local law that most closely approximates
 an absolute waiver of all civil liability in connection with the
 Program, unless a warranty or assumption of liability accompanies a
 copy of the Program in return for a fee.
                     END OF TERMS AND CONDITIONS
            How to Apply These Terms to Your New Programs
  If you develop a new program, and you want it to be of the greatest
 possible use to the public, the best way to achieve this is to make it
 free software which everyone can redistribute and change under these terms.
  To do so, attach the following notices to the program.  It is safest
 to attach them to the start of each source file to most effectively
 state the exclusion of warranty; and each file should have at least
 the "copyright" line and a pointer to where the full notice is found.
    PicHost - Self-hosted image hosting
    Copyright (C) 2026 O96u
    This program is free software: you can redistribute it and/or modify
    it under the terms of the GNU General Public License version 3 as
    published by the Free Software Foundation.
    This program is distributed in the hope that it will be useful,
    but WITHOUT ANY WARRANTY; without even the implied warranty of
    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
    GNU General Public License for more details.
    You should have received a copy of the GNU General Public License
    along with this program.  If not, see <https://www.gnu.org/licenses/>.
 Also add information on how to contact you by electronic and paper mail.
  If the program does terminal interaction, make it output a short
 notice like this when it starts in an interactive mode:
    <program>  Copyright (C) <year>  <name of author>
    This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
    This is free software, and you are welcome to redistribute it
    under certain conditions; type `show c' for details.
 The hypothetical commands `show w' and `show c' should show the appropriate
 parts of the General Public License.  Of course, your program's commands
 might be different; for a GUI interface, you would use an "about box".
  You should also get your employer (if you work as a programmer) or school,
 if any, to sign a "copyright disclaimer" for the program, if necessary.
 For more information on this, and how to apply and follow the GNU GPL, see
 <https://www.gnu.org/licenses/>.
  The GNU General Public License does not permit incorporating your program
 into proprietary programs.  If your program is a subroutine library, you
 may consider it more useful to permit linking proprietary applications with
 the library.  If this is what you want to do, use the GNU Lesser General
 Public License instead of this License.  But first, please read
 <https://www.gnu.org/licenses/why-not-lgpl.html>.

 ## Quick Start
 ### Docker (recommended)

-**Forgot password** (requires `docker exec` / server access):
+**Full guide** (env vars, upgrades, dual-domain setup, API, Twikoo, reverse proxy, local dev, etc.): **[Documentation](https://o96u.github.io/PicHost/en/)**.
-```bash
+| Branch | Notes |
-docker exec pichost reset-password              # admin only, when there is exactly one
+| ------ | ----- |
-docker exec pichost reset-password <username>   # admin or regular user
+| [**main**](https://github.com/O96u/PicHost/tree/main) | Default: multi-backend, dual-domain, unified `images/` storage |
-```
+| [**cloudflare**](https://github.com/O96u/PicHost/tree/cloudflare) | Cloudflare R2 only; live demo [pic.roven.cc](https://pic.roven.cc) |
 A random password is printed. Fails if the user does not exist.
 If you cloned the repo, you can also use `docker compose up -d` (see `docker-compose.yml`).
 ### Local development
 ```bash
 npm install
 cp .env.example .env   # optional
 npm run dev
 ```
 Open `http://localhost:3000/setup` to create the admin account. Data defaults to `./data`.
 ### Legacy migration
 If you only had `ADMIN_SECRET` and no user table, log in with the secret once and follow the migration wizard.
 ## Tech Stack
 | Layer | Technology |
 |-------|------------|
 | Frontend | Nuxt 4, Vue 3, Nuxt UI 4, Tailwind CSS 4 |
 | Backend | Nitro (Node.js), SQLite |
 | Images | sharp (WebP transcoding & compression) |
 | Auth | Session cookie, scrypt password hashing, API tokens |
 | Storage | Local disk (`DATA_DIR`) |
 | Deploy | Docker (amd64 / arm64), docker compose |
 | Tests | Vitest |
 ## Environment variables
 | Variable | Description |
 |----------|-------------|
 | `API_UPLOAD_TOKEN` | Global upload token (`Auth-Token` header); can be generated in the API page |
 | `ALLOWED_REFERER_HOSTS` | Hotlink allowlist (comma-separated hostnames) |
 | `IMAGE_BASE_URL` | Public base URL for image links |
 | `WEBP_QUALITY` | Server WebP quality 1–100, default 80 |
 | `AUTO_DELETE_DAYS` | Global auto-delete days (0 = off); admin + orphan images only |
 | `DATA_DIR` | Data directory, default `/data` (container) or `./data` (local) |
 | `ADMIN_SECRET` | Legacy v1.0 migration only |
 | `DEV_BYPASS_ACCESS` | Dev only — bypass auth (never in production) |
 Environment variables override database settings. See [`.env.example`](.env.example).
 ## Users & permissions
 | Scenario | Auth | Ownership / visibility |
 |----------|------|------------------------|
 | Web upload | Session | Current user |
 | API upload + **user token** | `Auth-Token` | Token owner |
 | API upload + **global token** | `Auth-Token` | Admin (`userId` null) |
 | Twikoo `/api/index.php` | form `token` | Same as global token |
 | Gallery list / search / delete | Session or token | Users: own only; admin: all |
 | Direct link `GET /images/...` | None (Referer rules) | Public if URL is known |
 Regular users are limited to the `images/` folder; custom `folder` requires admin or global token.
 ## Storage layout
 ```
 /data
 ├── pichost.db          # SQLite: users, sessions, settings, logs
 ├── images/             # Default upload folder
 ├── blog/               # Example custom folder
 └── twikoo/             # Twikoo comment images
 ```
 Pattern: `folder/YYYY/MM/randomId.webp` + `.meta.json`. Back up the entire `/data` directory.
 ## API overview
 | Method | Path | Description |
 |--------|------|-------------|
 | POST | `/api/images/upload` | Upload image |
 | GET | `/api/images` | Paginated list |
 | DELETE | `/api/images` | Delete one (`key`) |
 | POST | `/api/index.php` | Twikoo / EasyImage 2.0 |
 Upload example:
 ```bash
 curl -X POST "https://pic.example.com/api/images/upload" \
  -H "Auth-Token: YOUR_TOKEN" \
  -F "folder=blog" \
  -F "image=@./demo.png"
 ```
 Full docs and copyable cURL snippets are on the **API** page after deployment.
 ## Twikoo
 | Setting | Value |
 |---------|-------|
 | `IMAGE_CDN` | `easyimage` |
 | `IMAGE_CDN_URL` | `https://your-domain/api/index.php` |
 | `IMAGE_CDN_TOKEN` | Same as `API_UPLOAD_TOKEN` |
 ## Reverse proxy
 - Proxy to port **6892**; HTTPS recommended
 - Nginx: `client_max_body_size` ≥ 12m
 - Set `IMAGE_BASE_URL` for public access
 ## Development
 ```bash
 npm run dev          # Dev server
 npm run build        # Production build
 npm run start        # Run .output
 npm run lint         # ESLint
 npm run typecheck    # Type check
 npm test             # Unit tests
 ```
 ## Roadmap
 | Version | Plan |
 |---------|------|
 | **v1.0.2** | i18n, mobile menus, stats/upload UI, Docker password reset (current) |
 | **v1.0.1** | Settings version display, mobile upload preferences layout fix |
 | **v1.0.0** | Local storage, multi-user, API, Twikoo |
 | **v1.1.0** | S3, Cloudflare R2, and more object storage backends |

 # 指定用户名：可重置管理员或普通用户
 docker exec pichost reset-password 用户名
 ```
 终端会打印随机新密码；用户不存在时会报错。登录后请到「修改密码」更换。
 本地：`npm run reset-password` 或 `npm run reset-password -- 用户名`
 已克隆仓库时也可用 `docker compose up -d`（见仓库内 `docker-compose.yml`）。
 ### 本地开发
 ```bash
 npm install
 cp .env.example .env   # 可选
 npm run dev
 ```
 访问 `http://localhost:3000/setup` 创建管理员；数据目录默认 `./data`。
 ### 遗留部署迁移
 若旧版仅配置了 `ADMIN_SECRET`、尚无用户表，可用密钥登录一次，Web 引导迁移为账号密码。
 ## 技术栈
 | 层级 | 技术 |
 |------|------|
 | 前端 | Nuxt 4、Vue 3、Nuxt UI 4、Tailwind CSS 4 |
 | 后端 | Nitro（Node.js）、SQLite |
 | 图片处理 | sharp（WebP 转码与压缩） |
 | 鉴权 | Session Cookie、scrypt 密码哈希、API Token |
 | 存储 | 本地磁盘（`DATA_DIR`） |
 | 部署 | Docker（amd64 / arm64）、docker compose |
 | 测试 | Vitest |
 ## 环境变量
 | 变量 | 说明 |
 |------|------|
 | `API_UPLOAD_TOKEN` | 全局上传 Token（`Auth-Token` 头）；未配置可在后台 API 页生成 |
 | `ALLOWED_REFERER_HOSTS` | 防盗链白名单（逗号分隔 hostname） |
 | `IMAGE_BASE_URL` | 图片直链公网域名（反代时建议填写） |
 | `WEBP_QUALITY` | 服务端 WebP 质量 1–100，默认 80 |
 | `AUTO_DELETE_DAYS` | 全局自动删除天数（0 关闭）；仅影响管理员及无归属历史图 |
 | `DATA_DIR` | 数据目录，默认 `/data`（容器）或 `./data`（本地） |
 | `ADMIN_SECRET` | 仅遗留 v1.0 迁移，新安装不需要 |
 | `DEV_BYPASS_ACCESS` | 开发用，跳过登录（生产勿开） |
 环境变量优先级高于后台设置。详见 [`.env.example`](.env.example)。
 ## 用户与权限
 | 场景 | 鉴权 | 图片归属 / 可见范围 |
 |------|------|---------------------|
 | 网页上传 | Session | 当前登录用户 |
 | API 上传 + **个人 Token** | `Auth-Token` | 该 Token 所属用户 |
 | API 上传 + **全局 Token** | `Auth-Token` | 管理员（`userId` 为空） |
 | Twikoo `/api/index.php` | 表单 `token` | 与全局 Token 相同 |
 | 图库列表 / 搜索 / 删除 | Session 或 Token | 普通用户仅自己；管理员全部 |
 | 图片直链 `GET /images/...` | 无（Referer 防盗链） | 知道 URL 即可访问 |
 普通用户上传目录固定为 `images/`；自定义 `folder` 仅管理员或全局 Token 可用。
 ## 存储结构
 ```
 /data
 ├── pichost.db          # SQLite：用户、会话、设置、操作日志
 ├── images/             # 默认上传目录
 ├── blog/               # 管理员自定义 folder 示例
 └── twikoo/             # Twikoo 评论图片
 ```
 路径规则：`目录/年/月/随机ID.webp` + 同名 `.meta.json`。备份整个 `/data` 即可。
 ## API 概览
 | 方法 | 路径 | 说明 |
 |------|------|------|
 | POST | `/api/images/upload` | 上传图片 |
 | GET | `/api/images` | 分页列表 |
 | DELETE | `/api/images` | 删除单张（`key`） |
 | POST | `/api/index.php` | Twikoo / EasyImage 2.0 |
 上传示例：
 ```bash
 curl -X POST "https://pic.example.com/api/images/upload" \
  -H "Auth-Token: YOUR_TOKEN" \
  -F "folder=blog" \
  -F "image=@./demo.png"
 ```
 完整接口与可复制 cURL 见部署后后台 **API** 页。
 ## Twikoo
 | 配置项 | 值 |
 |--------|-----|
 | `IMAGE_CDN` | `easyimage` |
 | `IMAGE_CDN_URL` | `https://你的域名/api/index.php` |
 | `IMAGE_CDN_TOKEN` | 与 `API_UPLOAD_TOKEN` 相同 |
 ## 反向代理
 - 反代到容器 **6892** 端口，建议 HTTPS
 - Nginx：`client_max_body_size` ≥ 12m
 - 公网访问请配置 `IMAGE_BASE_URL`
 ## 开发
 ```bash
 npm run dev          # 开发服务器
 npm run build        # 生产构建
 npm run start        # 运行 .output
 npm run lint         # ESLint
 npm run typecheck    # 类型检查
 npm test             # 单元测试
 ```
 ## 路线图
 | 版本 | 计划 |
 |------|------|
 | **v1.0.2** | 中英文、移动端菜单、统计/上传 UI、Docker 重置密码（当前） |
 | **v1.0.1** | 设置页版本展示、移动端上传偏好布局修复 |

 # API
 PicHost exposes REST endpoints and a Twikoo-compatible upload. After sign-in, open **API** in the nav: a sidebar lists endpoints and token controls, the center shows parameters and copyable cURL, and the right panel supports **live debugging**.
 ## Authentication
 All REST calls use:
 ```http
 Auth-Token: YOUR_TOKEN
 ```
 | Token type | How to obtain | Notes |

 ## Endpoints
 ### 1. Upload images
 `POST /api/images/upload`
 Upload one or more images via `image`; also accepts `file`, `files`. Stored under `images/`.
 ```bash
 curl -X POST "https://admin.example.com/api/images/upload" \
  -H "Auth-Token: YOUR_TOKEN" \
  -F "image=@./demo.png"
 ```
 ### 2. List images
 `GET /api/images`
 Paginated gallery. `limit` default 20, max 100.
 ```bash
 curl "https://admin.example.com/api/images?limit=20&page=1" \
  -H "Auth-Token: YOUR_TOKEN"
 ```
 ### 3. Search images
 `GET /api/images/search`
 Search by filename or path; `q` is required.
 ```bash
 curl "https://admin.example.com/api/images/search?q=demo&limit=20&page=1" \
  -H "Auth-Token: YOUR_TOKEN"
 ```
 ### 4. Delete image
 `DELETE /api/images`
 Delete by `key` (storage path, e.g. `images/2026/08/xxx.webp`).
 ```bash
 curl -X DELETE "https://admin.example.com/api/images?key=images/2026/08/xxxx.webp" \
  -H "Auth-Token: YOUR_TOKEN"
 ```
 ### 5. Batch delete
 `POST /api/images/batch-delete`
 JSON body: `{"keys":["images/2026/08/a.webp","images/2026/08/b.webp"]}`
 ```bash
 curl -X POST "https://admin.example.com/api/images/batch-delete" \
  -H "Auth-Token: YOUR_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{"keys":["images/2026/08/a.webp","images/2026/08/b.webp"]}'
 ```
 ## Errors
 REST responses are JSON with `code` and `message` (`UNAUTHORIZED`, `FORBIDDEN`, `INVALID_REQUEST`, etc.). Twikoo uses EasyImage-compatible JSON.
 ## Visibility
 - User token: list/search/delete own images only
 - Admin token: all images
 - Global token uploads belong to admin
 See [Users & permissions](./users-and-permissions.md).

 # Changelog
 Version history and notable changes. The full log is also in the repo root [CHANGELOG.md](https://github.com/O96u/PicHost/blob/main/CHANGELOG.md).
 ---
 ## [1.2.6] — 2026-09-01
 ### Added
 - **Admin UI**: redesigned Settings, API, Gallery, and Storage pages; API page includes live debugging
 - **Gallery filter**: filter by storage backend
 - **Storage IDs**: new R2 / COS / OSS / S3 backends get `r2-*`, `cos-*`, `oss-*`, or `s3-*` prefixes
 ### Improved
 - Activity log table styling and path truncation
 - Storage backend card metadata layout
 - Docs site and README screenshots updated
 ## [1.2.5] — 2026-08-31
 ### Added
 - **Gallery page**: nav “Stats” renamed to “Gallery” (`/gallery`); click a thumbnail for a detail modal (full image, dimensions, upload source, storage path, link copy)
 - **List actions**: select all / invert selection; single-image delete moved into the detail modal
 - **Upload source**: gallery API returns web / API upload source (from activity logs)
 ### Improved
 - README tech stack section
 ### Removed
 - `/stats` route (no compatibility redirect)
 ## [1.2.4] — 2026-08-31
 ### Fix
 - **Empty referer whitelist still blocked hotlinks**: with no Referer whitelist configured, direct browser access worked but embedded images on blogs/forums returned 403; protection now runs only when a whitelist is configured
 ## [1.2.3] — 2026-08-30
 ### Fix
 - **Short links + date-based storage**: bare filename URLs (e.g. `https://host/xxx.webp`) no longer map to flat `images/xxx.webp`; SQLite index resolves the full `images/YYYY/MM/xxx.webp` key so thumbnails and short links work again
 ---
 ## [1.2.2] — 2026-08-30
 > **Restart the service** after upgrading so middleware and API updates take effect.
 ### Dual-domain settings & Host isolation
 #### Fixes
 | Issue | Description |
 | ----- | ----------- |
 | Site URL cleared by mistake | Saving Settings could write an empty `site_base_url` when disabling dual-domain or editing only the image URL |
 | Config vs effective URL mixed | `GET /api/settings` used to blend DB values with `request.origin`, confusing the Settings UI |
 | Third-host bypass | Unlisted hosts (`pages.dev`, bare IP, old image domains) were not blocked by middleware |
 #### Improvements
 **Settings API (`GET /api/settings`)**
 | Field | Meaning |
 | ----- | ------- |
 | `siteBaseUrl` / `imageBaseUrl` | **Configured** values (DB → env), no request fallback |
 | `effectiveSiteBaseUrl` / `effectiveImageBaseUrl` | **Link generation**, falls back to request origin when unset |
 | `runtime.currentOrigin` | Detected access URL (display only, not saved) |
 | `runtime.hostRole` | `site` / `image` / `unknown` / `single` |
 **Save API (`PATCH /api/settings`)**
 - New body field `domainSeparation` (`true` / `false`)
 - `domainSeparation: true` requires both URLs with different hostnames
 - `domainSeparation: false` allows clearing the site URL
 - Without `domainSeparation`, cannot clear `siteBaseUrl` while dual-domain is active
 **Settings / setup UI**
 - Form uses configured values; “Active” line shows `effective*`
 - Shows detected access URL; **no longer** auto-fills `window.location.origin`
 - “Use detected URL” button (opt-in)
 - Confirmation modal when disabling dual-domain
 - Warning when `hostRole === 'unknown'` with dual-domain on
 **Host middleware**
 - When dual-domain is on, unlisted hosts get **404** at the app layer (all methods)
 - `localhost` / `127.0.0.1` exempt in development
 - Complements Nginx `default_server` — use both layers in production
 #### Docs
 - Rewrote [Cloudflare deployment](./cloudflare-deployment.md)
 - Updated [Dual-domain separation](./domain-separation.md) for third-host blocking
 - Added this changelog page
 #### Upgrade notes
 - **No** database migration or CLI step
 - If the site URL was cleared earlier: re-enter it in **Settings**, or set `SITE_BASE_URL` in env and restart
 - Production: match proxy `server_name` to Settings; keep a default server block
 ---
 ## [1.2.1] — 2026-08-29
 ### Added
 - Slide puzzle login captcha
 - VitePress docs site on GitHub Pages
 - `npm run docs:dev` / `docs:build` / `docs:preview`
 ### Fixed
 - Gallery not refreshing after delete on stats page
 - Pagination jump with `type="number"` input
 - Copy-link format preference not persisting off home route
 - Captcha UI alignment
 ### Improved
 - README trimmed; details moved to docs
 - Dual-domain docs: unknown Host risk, Cloudflare guide
 ---
 ## [1.2.0] — 2026-08-28
 ### Changed
 - All images under `data/images/`; legacy `blog/` / `twikoo/` need migration
 ### Added
 - CLI: `docker exec pichost migrate` / `migrate --apply`
 - Startup index sync (disk scan, legacy key normalization, orphan cleanup)
 See [v1.2 migration](./migration.md).
 ---

 # Cloudflare & preferred-edge deployment
 In dual-domain mode, PicHost distinguishes **site** vs **image** traffic from the request **Host** (and `X-Forwarded-Host` from a trusted reverse proxy). Cloudflare orange cloud, preferred-edge IPs, Workers, and Pages are all fine — as long as the hostname identity reaching PicHost stays correct.
 > **One-line rule:** The network path may change; the hostname identity must not — `admin → admin`, `img → img`, never `img → admin`.
 See [Dual-domain separation](./domain-separation.md) for middleware behavior and [Reverse proxy](./reverse-proxy.md) for general proxy requirements.
 ---
 ## Quick checklist
 | # | Check | Expected |
 | - | ----- | -------- |
 | 1 | Browser hostname | `admin.*` or `img.*`; do not mix IP / `pages.dev` |
 | 2 | Pages / Worker in the middle | Image host must **not** `fetch(admin…)` |
 | 3 | Reverse-proxy upstream | Both hostnames → `http://127.0.0.1:6892` |
 | 4 | Nginx `proxy_set_header Host` | `$host` (preserve client hostname) |
 | 5 | PicHost settings | `SITE_BASE_URL` / `IMAGE_BASE_URL` match `server_name` |
 | 6 | Port `6892` | Reachable only from localhost or internal proxy |
 ---
 ## Recommended layout
 Both hostnames go through Cloudflare (proxied) and **independently** reverse-proxy to one PicHost instance:
 ```mermaid
 flowchart TB
  internet[Internet]
  cf[Cloudflare proxied]
  admin[admin.example.com]
  img[img.example.com]
  panel[1Panel / Nginx]
  app[PicHost :6892]
  internet --> cf
  cf --> admin
  cf --> img
  admin --> panel
  img --> panel
  panel --> app
 ```
 ```env
 SITE_BASE_URL=https://admin.example.com
 IMAGE_BASE_URL=https://img.example.com
 ```
 ```text
 admin.example.com → http://127.0.0.1:6892
 img.example.com   → http://127.0.0.1:6892
 ```
 You do **not** need separate ports for “frontend / backend / images” — one PicHost instance on port `6892` is enough.
 ### Site hostname ≠ frontend domain
 | Hostname | Serves |
 | -------- | ------ |
 | `admin.example.com` | Admin UI, login, settings, gallery, API, upload |
 | `img.example.com` | Image delivery, hotlinks, CDN |
 Use **site / image hostname**, not “frontend / backend”. PicHost does **not** require `frontend :3000 + backend :6892` in production.
 ---
 ## Orange cloud & preferred edge
 **DNS Proxied (orange cloud)** is normal and recommended:
 ```text
 admin.example.com, img.example.com
  A/CNAME → origin → Proxied
 ```
 Opening `admin.example.com` should yield `Host: admin.example.com` at PicHost; `img.example.com` should yield `Host: img.example.com`.
 **Preferred-edge** setups (alternate IPs, entry hostnames) are also fine. Preferred routing may change the path to Cloudflare’s edge, but must **not** rewrite the image hostname’s origin identity to the site hostname:
 ```text
 admin → CF → admin.example.com → origin → PicHost
 img   → CF → img.example.com   → origin → PicHost
 ```
 ---
 ## 6. Typical bad topologies
 These patterns break Host isolation even when the browser still shows the image hostname:
 ### ❌ Bad 1: Image host fetches site host
 ```mermaid
 flowchart LR
  user[User on img.example.com]
  worker[Pages / Worker]
  admin[fetch admin.example.com]
  app[PicHost]
  user --> worker --> admin --> app
 ```
 The last hop has `Host: admin.example.com`, so PicHost treats it as site traffic — `https://img.example.com/` may show the admin UI. This is **Host rewrite**, not a cache bug.
 ### ❌ Bad 2: Preferred proxy upstreams to site host
 ```text
 img.example.com → preferred hostname → admin.example.com → origin
 ```
 Even for routing only, using the site hostname as upstream breaks image isolation.
 ### ❌ Bad 3: Public exposure of port 6892
 ```text
 any host / IP:6892 → PicHost
 ```
 Users can bypass Cloudflare and Nginx `server_name` rules. Port `6892` should be reachable only from `127.0.0.1` or an internal reverse proxy.
 ### ✅ Correct pattern
 ```text
 admin → admin → PicHost
 img   → img   → PicHost
 ```
 Do **not** use Pages / Workers as a **full-site reverse proxy** for PicHost (extra `pages.dev` / `workers.dev` entry points). PicHost needs `node-server`, SQLite, `sharp`, and local `data/` — it **cannot** run as a Node app on Pages/Workers. Keep Docker/VPS for the app; use orange-cloud DNS and optional R2 on CF.
 ---
 ## Workers / Pages guidance
 If you only need headers, auth, Referer rules, logging, or cache — and PicHost remains your origin:
 | Prefer | Avoid |
 | ------ | ----- |
 | `img.example.com` → **Worker Route** → existing `img` origin | `img` → Worker → `fetch(admin.example.com)` |
 Cloudflare recommends [Routes](https://developers.cloudflare.com/workers/configuration/routing/routes/) when an external origin already exists, rather than [Custom Domains](https://developers.cloudflare.com/workers/configuration/routing/custom-domains/) used to chain cross-host `fetch()`.
 Code like this on the image hostname is a smoking gun:
 ```js
 fetch(`https://admin.example.com${url.pathname}`)
 ```
 ---
 ## Nginx / 1Panel layout
 Two `server` blocks, same upstream. Critical line: `proxy_set_header Host $host;`
 ```nginx
 server {
    server_name admin.example.com;
    location / {
        proxy_pass http://127.0.0.1:6892;
        proxy_set_header Host $host;
        proxy_set_header X-Forwarded-Proto $scheme;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        client_max_body_size 12m;
    }
 }
 server {
    server_name img.example.com;
    location / {
        proxy_pass http://127.0.0.1:6892;
        proxy_set_header Host $host;
        proxy_set_header X-Forwarded-Proto $scheme;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    }
 }
 # Reject bare IP and unknown hostnames (strongly recommended)
 server {
    listen 80 default_server;
    listen 443 ssl default_server;
    server_name _;
    return 444;
 }
 ```
 With orange cloud, restrict the origin firewall to **[Cloudflare IP ranges](https://www.cloudflare.com/ips/)** only.
 ---
 ## Two-layer Host protection
 Use reverse proxy and application layers **together**:
 | Layer | Role |
 | ----- | ---- |
 | **Nginx default server** | Reject bare IP, `pages.dev`, and other undeclared hostnames |
 | **PicHost middleware (v1.2.x+)** | When dual-domain is on, unconfigured hosts get 404 at the app (`localhost` / `127.0.0.1` exempt in development) |
 Even with app-layer blocking, keep a default server at the proxy to reduce junk traffic to PicHost.
 ---
 ## X-Forwarded-Host
 PicHost may consult `X-Forwarded-Host` behind a reverse proxy, but that header is **forgeable** by clients. Therefore:
 - Do not expose port `6892` publicly
 - Only trusted proxies should reach the app
 - Prefer keeping `Host` correct from the first hop
 ---
 ## Troubleshooting: admin UI on image hostname?
 **Inspect the proxy chain first — do not purge CF cache first.**
 Cache issues usually mean stale JS/CSS/images or occasional 404s. If `/`, `/login`, and `/settings` work **reliably** on the image host, the Host was almost certainly rewritten.
 ```text
 ① Browser hostname?
 ② Pages / Worker / preferred proxy in the middle?
 ③ What URL does the proxy fetch?
 ④ Does it fetch admin.example.com?
 ⑤ Which Host does 1Panel / PicHost see?
 ```

 # Environment variables
 Configure PicHost via environment variables (Docker / `.env`) or the in-app **Settings** page. Admins use **Settings** (`/settings`) with sidebar sections **Basic**, **Domains & paths**, **Access control**, and **Activity log**. Most values prefer **SQLite** when saved; some env vars override or lock UI editing.
 ## Priority overview
 | Setting | Priority (high → low) | Env overrides UI |
 | ------- | --------------------- | ---------------- |
 | API upload token | Env → SQLite | **Yes** (cannot regenerate in UI) |
 | WebP quality | SQLite → env → default 80 | No |
 | Referer whitelist | SQLite → env | No |
 | Site / image base URL | SQLite → env (configured in API); links use `effective*` or request origin | No |
 | Short image links | SQLite → env → default false | No |
 | Date-based paths | SQLite → env → default true | No |
 | Global auto-delete days | SQLite → env → default 0 | No |
 ## Variables
 ### `API_UPLOAD_TOKEN`
 Token for external uploads (Twikoo, userscripts, blogs). Header: `Auth-Token: <token>`; form field `token` still works.
 - Generate in **API** page when unset
 - **When set in env, it wins** — UI shows “overridden by environment” and cannot regenerate
 - Alias: `NUXT_API_UPLOAD_TOKEN`
 ### `ALLOWED_REFERER_HOSTS`
 Comma-separated Referer whitelist. Own hostnames are allowed automatically. Optional; configurable in Settings.
 ### `SITE_BASE_URL` / `IMAGE_BASE_URL`
 - **Site URL**: admin UI, API, Twikoo upload
 - **Image URL**: copied links and public image URLs
 Single-domain: set `IMAGE_BASE_URL` only or leave empty (request origin). Dual-domain: hostnames must differ — see [Dual-domain separation](./domain-separation.md) and [Cloudflare deployment](./cloudflare-deployment.md). Values must match proxy `server_name`; do not use `localhost`, IP, or unlisted hostnames for production admin access.
 In **Settings**, enable dual-domain explicitly and fill both URLs; disabling clears the site URL (with confirmation). Configured values vs effective link URLs are separate in the API — see [Changelog](./changelog.md#1-2-2-2026-08-30).
 ### `HIDE_FOLDER_IN_URL`
 `true`: short links (domain + filename only), e.g. `img.example.com/a8K3xP.webp`. `false`: keep date or custom folders, e.g. `img.example.com/2026/08/a8K3xP.webp`. Public URLs never expose the internal `images/` prefix; legacy `/images/...` paths still work.
 ### `STORAGE_USE_DATE_PATH` / `STORAGE_LAYOUT`
 - `true` or `STORAGE_LAYOUT=date` (default): `images/YYYY/MM/id.webp`
 - `false` or `STORAGE_LAYOUT=flat`: `images/id.webp`
 Also toggled in Settings.
 ### `DATA_DIR`
 Root for images and SQLite. Default `./data`; `/data` in container.
 ### `WEBP_QUALITY`
 Server WebP quality 1–100, default **80**.
 ### `AUTO_DELETE_DAYS`
 Delete images older than N days globally; `0` disables. Affects **new uploads after enable** only. Also in Settings.
 ### `DEV_BYPASS_ACCESS`
 Local dev only: `true` bypasses login. Never use in production.
 ### Storage backends (optional)
 Admins usually add backends in **Storage** UI; env vars such as `STORAGE_BACKEND=s3` and `S3_*` are also supported. See [Storage](./storage.md).
 ## Docker Compose example
 ```yaml
 services:
  pichost:
    image: muxui/pichost:latest
    ports:
      - "6892:6892"
    volumes:
      - ./data:/data
    environment:
      SITE_BASE_URL: https://admin.example.com
      IMAGE_BASE_URL: https://pic.example.com
      API_UPLOAD_TOKEN: your-secret-token
      WEBP_QUALITY: "85"
 ```
 Restart the container after changing env vars.

 # Dual-domain separation · Recommended deployment
 When admin and image domains are split, the admin UI, API, and public image links use different hostnames. PicHost enforces isolation in **application middleware**: the image host only serves image paths; other requests return 404.
 ## Architecture
 **One Docker instance + two domains**, both **fully reverse-proxied** to port `6892` (isolation is handled by PicHost middleware; no path splitting in Nginx).
 | Domain | Purpose |
 | ------ | ------- |
 | `admin.example.com` | Admin UI, API, Twikoo upload |
 | `pic.example.com` | Public image links (non-image paths blocked) |
 Set during `/setup` or in **Settings**:
 - **Site URL**: `https://admin.example.com`
 - **Image URL**: `https://pic.example.com`
 Setup and Settings **do not** auto-fill the site URL from `window.location.origin`; use manual input or “Use detected URL”. Disabling dual-domain requires confirmation and clears the site URL. Saves include `domainSeparation: true/false`. See [Changelog](./changelog.md#1-2-2-2026-08-30).
 ## Nginx example
 ```nginx
 # admin.example.com — admin + API
 server {
  server_name admin.example.com;
  location / {
    proxy_pass http://127.0.0.1:6892;
    proxy_set_header Host $host;
    proxy_set_header X-Forwarded-Proto $scheme;
    client_max_body_size 12m;
  }
 }
 # pic.example.com — same full proxy; PicHost middleware blocks non-image paths
 server {
  server_name pic.example.com;
  location / {
    proxy_pass http://127.0.0.1:6892;
    proxy_set_header Host $host;
    proxy_set_header X-Forwarded-Proto $scheme;
  }
 }
 # Default server: reject bare IP and unknown Host values (strongly recommended in production)
 server {
  listen 443 ssl default_server;
  listen 80 default_server;
  server_name _;
  return 444;
 }
 ```
 > Caddy, NPM, and similar tools work the same: proxy both hostnames to `http://<host>:6892` and forward `Host` and `X-Forwarded-Proto`.
 ## Security notes
 ### Middleware isolation and third hosts
 PicHost uses the request **Host** (and `X-Forwarded-Host` when proxied) to decide site vs image domain:
 - **Image host**: non-image paths (e.g. `/`, `/settings`) → 404
 - **Site host**: image URL paths (e.g. `/images/...`) → 404
 - **Unconfigured third hosts** (e.g. `*.pages.dev`, bare IP, old image domains): **from v1.2.x the app returns 404 for all methods** (`localhost` / `127.0.0.1` are exempt in development for `npm run dev`)
 This is independent of hyphenated or long domain names. Older versions did not block third hosts; rely on a reverse-proxy default server as a complement in production.
 **Production recommendations:**
 1. Configure `server_name` only for the site and image hosts; add a **default server** to reject other Host values and bare IP access (see Nginx example above; complements app-layer blocking)
 2. With Cloudflare **orange-cloud** DNS, restrict the origin firewall to **[Cloudflare IP ranges](https://www.cloudflare.com/ips/)** so traffic cannot bypass the CDN
 3. Sign in only on the **site hostname** from Settings; do not mix `localhost`, IP, or unlisted domains
 4. Do **not** put Cloudflare Pages / Workers in front of PicHost as a **full-site reverse proxy** (`IMAGE_BASE_URL` may point at a CDN URL, but the app itself should run on Docker/VPS)
 5. If you must proxy at the edge, preserve the client **`Host` or `X-Forwarded-Host`** or host isolation will fail
 6. PicHost **cannot** run as-is on Pages/Workers (needs `node-server`, SQLite, `sharp`, local `data/`). Keep Docker/VPS; use orange-cloud DNS and optional R2 storage on CF
 ### Cloudflare orange cloud (incl. preferred edge IPs)
 Full guide: [Cloudflare deployment](./cloudflare-deployment.md).
 **Recommended:** both `admin.example.com` and `pic.example.com` **DNS Proxied** → origin Nginx / 1Panel → port `6892`, SSL **Full (strict)**.
 | Feature | Notes |
 | ------- | ----- |
 | Orange-cloud CDN | Compatible with dual-domain; preserve `Host` and `X-Forwarded-Proto` on origin |
 | DNS “preferred IP” setups | Only changes which CF edge IP clients hit; origin identity must stay **admin → admin**, **img → img** |
 | R2 storage | Add an R2 backend under **Storage**; independent of orange cloud |
 | `cloudflare` Git branch | R2-focused deployment line; still Docker, **not** Workers hosting |
 **Do not confuse** “Create Worker” in the CF dashboard (Git + `wrangler deploy`) with deploying PicHost — the repo uses `nitro.preset: 'node-server'` and is not Workers-ready.
 **Do not** chain the image hostname to `fetch(admin…)` via Pages/Workers — that rewrites Host and breaks isolation ([bad topologies](./cloudflare-deployment.md#6-typical-bad-topologies)).
 See [Reverse proxy](./reverse-proxy.md#cloudflare-orange-cloud) for origin hardening.
 ## FN NAS · Lucky reverse proxy
 In [Lucky](https://github.com/gdy666/lucky), create one **reverse proxy** rule per domain. **Frontend** is the public hostname; **backend** is PicHost on your LAN (e.g. `http://192.168.8.3:6892`).
 **Site domain (admin)**
 | Field | Example |
 | ----- | ------- |
 | Service type | Reverse proxy |
 | Frontend | `admin.pichost.com` |
 | Backend | `http://192.168.8.3:6892` |
 **Image domain**
 | Field | Example |
 | ----- | ------- |
 | Service type | Reverse proxy |
 | Frontend | `image.pichost.com` |
 | Backend | `http://192.168.8.3:6892` |
 Both rules can point to the same backend; PicHost applies host-based isolation automatically.
 ## Environment variables (optional)
 ```env
 SITE_BASE_URL=https://admin.example.com
 IMAGE_BASE_URL=https://pic.example.com
 ```
 See [Environment variables](./configuration.md).
 ## Local testing (Windows / macOS)
 ### 1. Edit hosts
 ```text
 127.0.0.1 admin.pichost.test
 127.0.0.1 pic.pichost.test
 ```
 Prefer the `.test` TLD; avoid `.local` where it conflicts with mDNS.
 ### 2. Start dev server
 ```bash
 npm run dev
 ```
 Dev binds `127.0.0.1:3000` by default. If the hostname resolves but the browser cannot connect, check whether dev is listening on IPv6 `::1` only.
 ### 3. Configure dual domains
 | Field | Example |
 | ----- | ------- |
 | Site URL | `http://admin.pichost.test:3000` |
 | Image URL | `http://pic.pichost.test:3000` |
 Always open admin on the **site hostname**, not `localhost` (cookies and Host must match).
 ### 4. Expected behavior
 | URL | Expected |

 ## Notes
 - Hostnames must **differ** (same machine, different subdomains is fine)
 - Site / image URLs in Settings must **exactly match** proxy `server_name` (including `www` or not)
 - No separate static root on the image domain; unlike EasyImages, PicHost isolates in-app
 - Single-domain setups can skip separation and use `IMAGE_BASE_URL` or the request host
 - When Referer protection is enabled, site and image hosts are whitelisted automatically

 # FAQ
 ## Forgot the admin password?
 With `docker exec` access:
 ```bash
 docker exec pichost reset-password
 docker exec pichost reset-password <username>
 ```
 Local: `npm run reset-password`. See [Quick start](./getting-started.md#forgot-password).
 ## Why can’t I regenerate the API token in the UI?
 `API_UPLOAD_TOKEN` in the environment **locks** the token. Change env and **restart**. See [Environment variables](./configuration.md#api-upload-token).
 ## Hotlink / Referer errors?
 Check the **Referer whitelist** (`ALLOWED_REFERER_HOSTS` or Settings). Referring sites must be listed; PicHost’s own hosts and dual-domain pair are allowed automatically.
 ## Why can admin load on pages.dev / workers.dev / IP with dual-domain?
 **From v1.2.2:** when dual-domain is on, PicHost returns **404** for Host values **other than** the configured site and image hostnames (`localhost` / `127.0.0.1` exempt in development). See [Changelog](./changelog.md#1-2-2-2026-08-30).
 If admin still loads:
 1. **Dual-domain not active** (image URL set but site URL empty) — neither path split nor third-host blocking applies
 2. **Proxy rewrote Host to site hostname** — e.g. Pages/Worker `fetch(admin…)` on the image hostname
 3. **Port `6892` exposed publicly** — bypasses Cloudflare and Nginx `server_name`
 Fix: configure both URLs in Settings; add a default server block; with orange cloud, allow only CF IPs on origin; do not full-proxy through Pages/Workers. See [Dual-domain separation](./domain-separation.md#middleware-isolation-and-third-hosts), [Cloudflare deployment](./cloudflare-deployment.md), and [Changelog](./changelog.md#1-2-2-2026-08-30).
 ## Can I deploy PicHost on Cloudflare Workers / Pages?
 **Not with the current codebase.** PicHost needs `node-server`, SQLite, `sharp`, and local `data/` — use Docker/VPS. Connecting the repo in “Create Worker” will not deploy successfully.
 Recommended: run PicHost on origin; use **proxied DNS** (and optional **R2** storage). Do not full-proxy the app through Pages/Workers.
 ## Dual-domain: admin works but thumbnails break?
 - Verify **IMAGE_BASE_URL** and proxy to the same instance
 - Always open admin on the **site hostname**, not mixed with `localhost`
 - See [Dual-domain separation](./domain-separation.md)
 ## Undeletable gallery items after v1.2 upgrade?
 Likely **orphan index** rows (no file on disk). Startup sync removes them on restart. See [v1.2 migration](./migration.md#step-2-startup-index-sync-automatic).
 ## Do I still need `data/blog/` after migration?
 After `migrate --apply`, files live under `data/images/blog/`. Remove leftover empty dirs after backup if you like; dirs with non-image files are kept by the CLI.
 ## Object storage only — run migrate?
 No. Skip the CLI; startup sync focuses on local `data/images/` scanning.
 ## Replace old image URLs in posts?
 Use `data/mapping.json` from `migrate` preview. Keys are **storage paths**, not full legacy URLs. See [Migration](./migration.md#urls).
 ## Skip login during development?
 `DEV_BYPASS_ACCESS=true` (local only). Use `/setup` for normal flows.

 # Quick start
 PicHost is a self-hosted image host for NAS, home servers, or VPS. Docker is recommended; the first visit runs a web wizard to create the admin account.
 ## Try it online
 | Branch | Notes |
 | ------ | ----- |
 | **main** | No public demo — see [screenshots](./index.md#screenshots) or the repository README |
 | **cloudflare** | R2-only live demo: [pic.roven.cc](https://pic.roven.cc) |
 ## Docker (recommended)
 ```bash
 docker run -d \
  --name pichost \
  -p 6892:6892 \
  -v ./data:/data \
  --restart unless-stopped \
  muxui/pichost:latest
 ```
 Default port: **6892**. Open `http://<host>:6892` and complete setup.
 If you cloned the repo:
 ```bash
 docker compose up -d
 ```
 See `docker-compose.yml` in the repository.
 ## First-time setup
 1. Open your instance URL (Docker default `http://<host>:6892`).
 2. Complete `/setup` with admin username and password.
 3. (Optional) Configure site URL, image URL, Referer rules — see [Environment variables](./configuration.md) and [Dual-domain separation](./domain-separation.md).
 4. Upload from the home page; use the top nav for **Gallery**, **Storage** (admin), **Settings**, and **API**.
 ## Sign in
 Management pages (upload, gallery, settings, etc.) require login. Enter username and password, **drag the slider to align with the gap**, then click **Sign in**.
 ![Login](/screenshots/login.png)
 If registration is enabled, create an account from the register page. Legacy deployments may still use a secret key (see the on-screen hint).
 ## Forgot password
 Requires `docker exec` (server access):
 ```bash
 docker exec pichost reset-password              # admin only when there is exactly one
 docker exec pichost reset-password <username> # admin or regular user
 ```
 A random password is printed. Change it after login.
 Local dev: `npm run reset-password` or `npm run reset-password -- <username>`
 ## Upgrading to v1.2.0
 If `data/` has legacy top-level folders next to `images` (e.g. `blog/`, `twikoo/`), read the [v1.2 migration guide](./migration.md) first.
 Object-storage-only or files already under `data/images/` — pull the new image and restart.

 # v1.2.0 local disk migration guide
 From v1.2.0, **all local image files** live under `data/images/`; SQLite `keys` also start with `images/`. Legacy top-level folders next to `images` (e.g. `data/blog/`, `data/twikoo/`) are no longer used.
 Migration is **two steps**: run the **CLI** to move files on disk, then let **startup sync** align the SQLite index.
 ---
 ## Migrating from other image hosts (EasyImage, Lsky, Chevereto, …)
 There is **no** dedicated “pull from URLs” or “import via vendor API” tool. Moving from **legacy PicHost** or **another self-hosted** install uses the same **local file** workflow:
 1. Locate the **image files** on the old server (copy the tree, not just the database).
 2. Place them under PicHost `data/` as a **top-level folder** next to `images` (any name — it becomes `images/{name}/...`).
 3. Run `migrate` / `migrate --apply`, then restart PicHost.
 | Source | Typical path on old server | After copy into PicHost |
 | ------ | -------------------------- | ----------------------- |
 | PicHost v1.1.x | `data/blog/`, `data/twikoo/` | Already under `data/` → run `migrate` |
 | EasyImage(s) | `i/` or `upload/` | e.g. `data/easyimage/` → `migrate` |
 | Lsky | `public/uploads/` etc. | e.g. `data/lsky/` → `migrate` |
 | Chevereto etc. | `images/` or `content/` | e.g. `data/chevereto/` → `migrate` |
 | Custom | your folder name | `data/your-folder/` → `migrate` |
 The CLI scans **every top-level directory under `data/` except `images`**, not only `blog` / `twikoo`.
 **Limits:** files only — accounts, tokens, and old public URLs are not imported. `mapping.json` maps old **storage keys**, not full old-site URLs. For S3/R2-only legacy hosts, sync blobs to `data/…` or attach the bucket in PicHost **Storage** settings.
 ---
 ## Layout before and after
 ### Before (typical v1.1.x)
 ```
 /data
 ├── pichost.db
 ├── blog/
 │   └── 2026/08/TeKJ2fD6cB6j.webp
 ├── twikoo/
 └── images/
 ```
 Index keys might look like `blog/2026/08/TeKJ2fD6cB6j.webp`.
 ### After (v1.2.0)
 ```
 /data
 ├── pichost.db
 ├── mapping.json
 └── images/
    ├── blog/
    │   └── 2026/08/TeKJ2fD6cB6j.webp
    └── twikoo/
 ```
 Index key: `images/blog/2026/08/TeKJ2fD6cB6j.webp`.
 ---
 ## Step 1: CLI file migration
 Run **before or after** upgrading the image; backup `data/` first.
 ```bash
 docker exec pichost migrate          # preview + mapping.json
 docker exec pichost migrate --apply  # move files
 ```
 Local: `npm run migrate` / `npm run migrate -- --apply`.
 | Item | Behavior |
 | ---- | -------- |
 | Scan | Every top-level directory under `data/` **except `images`** |
 | Target | `data/images/{original-top-dir}/{relative-path}` |
 | Extensions | jpg, jpeg, png, webp, gif, svg, ico |
 | Sidecar | `.meta.json` next to an image is moved if present |
 | Other files | Not moved; parent directory kept if anything remains |
 | Mapping | `data/mapping.json` — old key → new key |
 Script: `server/cli/migrate-to-single-images.mjs`.
 ---
 ## Step 2: Startup index sync (automatic)
 Runs on every start (`npm run dev`, Docker). No manual command.
 ```text
 [INFO] 开始同步图片索引：扫描本地磁盘 ...
 [INFO] 磁盘扫描完成：...
 [INFO] 开始归一化遗留图片路径 ...
 [INFO] 开始校验索引与磁盘一致性，清理无文件的孤儿记录
 [INFO] 图片索引同步结束
 ```
 | Step | Purpose |
 | ---- | ------- |
 | Scan `data/images/` | Insert missing index rows for files on disk |
 | Normalize legacy keys | `blog/...` → `images/blog/...` when files are in place |
 | Purge orphans | Remove index rows with no file on disk |
 | Repair Content-Type | Fix `application/octet-stream` entries |
 The CLI only **moves files**. Index alignment runs at startup — **restart** after `migrate --apply`.
 ---
 ## Recommended upgrade flow
 1. Backup `data/`.
 2. `docker exec pichost migrate` — review output and `mapping.json`.
 3. `docker exec pichost migrate --apply`.
 4. Deploy v1.2.0 and restart.
 5. Check logs for successful index sync.
 6. Use `mapping.json` to update external URLs if needed.
 Skip step 1 if you only use object storage or everything is already under `data/images/`.
 ---
 ## URLs
 | Old key | `blog/TeKJ2fD6cB6j.webp` |
 | New key | `images/blog/TeKJ2fD6cB6j.webp` |
 With “hide folder” mode, short URLs like `/TeKJ2fD6cB6j.webp` may still resolve by filename. Use `mapping.json` for bulk replacements.

 # Reverse proxy
 In production, terminate HTTPS with Nginx, Caddy, NPM (Nginx Proxy Manager), or your NAS proxy and forward to PicHost on port **6892**.
 ## Basics
 - Upstream: `http://127.0.0.1:6892` (or host IP)
 - Forward: `Host`, `X-Forwarded-Proto` (and `X-Forwarded-For` as needed)
 - Body size: Nginx `client_max_body_size 12m` or larger
 - Use **HTTPS** on the public edge
 ## Single domain (Nginx)
 Admin, API, and images on one hostname:
 ```nginx
 server {
  server_name pic.example.com;
  location / {
    proxy_pass http://127.0.0.1:6892;
    proxy_set_header Host $host;
    proxy_set_header X-Forwarded-Proto $scheme;
    client_max_body_size 12m;
  }
 }
 ```
 Optional:
 ```env
 IMAGE_BASE_URL=https://pic.example.com
 ```
 Without `IMAGE_BASE_URL`, PicHost infers the public URL from forwarded headers.
 ## Dual domains
 Both hostnames can fully proxy to the same port; isolation is enforced in PicHost middleware.
 See [Dual-domain separation](./domain-separation.md).
 ## Cloudflare orange cloud
 See [Cloudflare deployment](./cloudflare-deployment.md).
 | Practice | Notes |
 | -------- | ----- |
 | **Proxied DNS** | Both admin and image hostnames → origin proxy to `6892`, SSL **Full (strict)** |
 | Preferred edge IPs | Compatible; keep **admin → admin**, **img → img** on origin |
 | **R2** | Object storage backend in **Storage**; not the same as hosting the app on Pages |
 | Origin firewall | Allow only [Cloudflare IPs](https://www.cloudflare.com/ips/); do not expose `6892` publicly |
 **Avoid:**
 - **Cloudflare Pages** (`*.pages.dev`) or **Workers** (`*.workers.dev`) as a **full-site reverse proxy**, or chaining the image host to `fetch(admin…)` — rewrites Host and bypasses dual-domain isolation ([guide](./cloudflare-deployment.md))
 - “Create Worker” from Git on this repo — `node-server` preset is not Workers-ready
 ## Origin hardening (dual-domain)
 PicHost middleware does **not** reject unlisted Host values. Complement with:
 1. **`server_name` allowlist** — site + image hosts only; `default_server` blocks bare IP and unknown Host
 2. **Do not expose 6892 on the public Internet** — only local reverse proxy; public 80/443 only
 3. **Orange cloud** — origin firewall limited to Cloudflare IP ranges
 ## Caddy
 ```caddy
 pic.example.com {
  reverse_proxy 127.0.0.1:6892
 }
 ```
 Add a second site block for the second hostname with the same upstream.
 ## Caching
 Image 404/403 and domain-isolation 404 responses are **no-cache** to avoid sticky CDN errors. Be careful caching API paths behind a CDN.

 # Storage
 PicHost supports **local disk** and **S3-compatible object storage** (Cloudflare R2, Tencent COS, Alibaba OSS, AWS S3, etc.). Admins manage backends at **Storage** (`/storage`); new uploads go to the **default** backend. The page shows a **storage overview** (total, used, remaining, usage rate, capacity chart) plus per-backend cards and supported backend types.
 ![Storage management](/screenshots/storage.png)
 ## Layout (local)
 ```
 /data
 ├── pichost.db          # SQLite: users, sessions, settings, storage_backends, images index
 └── images/             # All files when using local backend
 ```
 - New uploads: `images/randomId.webp` or `images/YYYY/MM/randomId.webp` (flat mode in Settings)
 - Migrated legacy: `images/blog/...` and similar
 - With cloud backends, blobs live in the bucket; index stays in SQLite `images`
 All **keys** start with `images/`. The upload API does **not** accept a `folder` parameter.
 ## Adding a backend
 1. Sign in as admin → **Storage** → **Add backend**.
 2. Choose **local disk** or **S3-compatible** (R2 / COS / OSS presets).
 3. Enter connection details (bucket, endpoint, keys).
 4. **Set as default** so new uploads use it.
 New object-storage backends get an auto-generated **storage ID** prefix: `local` for disk; `r2-*` for R2; `cos-*` for COS; `oss-*` for OSS; `s3-*` for AWS S3 and custom S3-compatible endpoints (immutable after creation; the image index references this ID).
 ### Cloudflare R2
 | Field | Value |
 | ----- | ----- |
 | Endpoint | `https://<account_id>.r2.cloudflarestorage.com` |
 | Region | `auto` |
 | Bucket | Your R2 bucket name |
 | Keys | R2 API token access / secret |
 The **cloudflare** branch streamlines R2-only deploys; see branch notes on the [docs overview](./index.md).
 ### Environment variables (optional)
 Some installs seed a default S3 backend via `STORAGE_BACKEND=s3`, `S3_ENDPOINT`, `S3_BUCKET`, `S3_ACCESS_KEY`, `S3_SECRET_KEY`, `S3_REGION`. **UI-configured backends live in SQLite** alongside env-based defaults.
 ## URL modes
 | Mode | Behavior |
 | ---- | -------- |
 | **proxy** | Serve via PicHost (`GET /images/...`) |
 | **public** | 302 redirect to bucket/CDN public URL |
 Copied links use **IMAGE_BASE_URL**. “Hide folder prefix” may shorten URLs; the server resolves by path or basename.
 ## Usage & gallery filter
 - Per-backend usage on the Storage page
 - Gallery filters by **storage backend** and **upload source**; grid/list view toggle
 ## Backup
 Back up `data/images/`, `data/pichost.db`, and bucket objects.

 # Twikoo
 PicHost supports **Twikoo** and **EasyImage 2.0** image upload — configure your comment system like EasyImage.
 ## Twikoo settings
 | Setting | Value |
 | ------- | ----- |
 | `IMAGE_CDN` | `easyimage` |
 | `IMAGE_CDN_URL` | `https://your-domain/api/index.php` |
 | `IMAGE_CDN_TOKEN` | Same as global `API_UPLOAD_TOKEN` |
 - Use your **site hostname** (admin domain) in `IMAGE_CDN_URL`
 - Generate the token in PicHost **API** or set `API_UPLOAD_TOKEN`
 ## Upload endpoint
 `POST /api/index.php`
 | Field | Description |
 | ----- | ----------- |
 | `image` | Image file |
 | `token` | Global API token (same as `Auth-Token`) |
 ```bash
 curl -X POST "https://admin.example.com/api/index.php" \
  -F "token=YOUR_TOKEN" \
  -F "image=@./demo.png"
 ```
 Files are stored under `images/` and owned by the **global token** account (admin).
 ## REST vs Twikoo
 | Aspect | REST `/api/images/upload` | Twikoo `/api/index.php` |
 | ------ | ------------------------- | ------------------------ |
 | Auth | `Auth-Token` header | form `token` |
 | Response | PicHost JSON | EasyImage-compatible JSON |
 | Token | Global or personal | Global only |
 ## Dual-domain
 Point Twikoo uploads at **SITE_BASE_URL**; public images use **IMAGE_BASE_URL**. See [Dual-domain separation](./domain-separation.md).

 # Users & permissions
 PicHost uses role-based access control (RBAC): **admin** and **user**. Enforcement is server-side.
 ## Role capabilities
 | Capability | Admin | User |
 | ---------- | :---: | :--: |
 | Upload images | ✓ | ✓ |
 | Own gallery | ✓ | ✓ |
 | All galleries / uploader badges | ✓ | — |
 | Storage management (`/storage`) | ✓ | — |
 | System settings (`/settings`) | ✓ | — |
 | Allow registration | ✓ | — |
 | Global API token | ✓ | — |
 | Personal API token | ✓ | ✓ |
 | Gallery stats overview (incl. user count) | ✓ | partial |
 | Activity log (Settings → Activity log) | ✓ | — |
 Regular users see **API**, **Gallery** in the nav; user menu: **Change password**, **Sign out**.
 ## Auth scenarios
 | Scenario | Auth | Ownership / visibility |
 | -------- | ---- | ---------------------- |
 | Web upload | Session cookie | Current user |
 | API upload + **user token** | `Auth-Token` header | Token owner |
 | API upload + **global token** | `Auth-Token` header | Admin (`userId` null) |
 | Twikoo `POST /api/index.php` | form `token` | Same as global token |
 | Gallery list / search / delete | Session or token | Users: own only; admin: all |
 | Direct link `GET /images/...` | None (Referer rules) | Public if URL is known |
 ## Accounts
 - By default only admins create users; **allow registration** is an admin setting
 - Passwords hashed with scrypt
 - Web login requires a slider captcha (align the thumb with the gap)
 - Login rate limiting
 ## Upload preferences & auto-delete
 - **Upload preferences**: admins configure client compression and auto-copy in **Settings → Basic**; regular users can flip the home upload card for personal preferences
 - **Auto-delete**: global (admin) and per-user policies; affects **new uploads after enable** only
 ## API tokens
 | Type | Managed by | Upload owner | Typical use |
 | ---- | ---------- | ------------ | ----------- |
 | **Global** | Admin (API page) | Admin account | Twikoo, site-wide scripts |
 | **Personal** | Each user (API page) | That user | Personal blog, private scripts |
 `API_UPLOAD_TOKEN` in env locks the global token — see [Environment variables](./configuration.md).

 # API
 PicHost 提供 REST 接口与 Twikoo 兼容端点。登录后打开顶栏 **API** 页：左侧为接口目录与 Token 管理，中间为参数说明与 cURL 示例，右侧可 **在线调试** 发送请求。
 ## 鉴权
 所有 REST 接口使用请求头：
 ```http
 Auth-Token: YOUR_TOKEN
 ```
 | Token 类型 | 获取方式 | 说明 |
 | ---------- | -------- | ---- |
 | **全局 Token** | 管理员 **API** 页生成；或 `API_UPLOAD_TOKEN` 环境变量 | 环境变量优先且锁定后台重新生成 |
 | **个人 Token** | 各用户 **API** 页 | 仅用于该用户脚本，上传归属本人 |
 表单上传仍可使用字段 `token`（Twikoo 协议）。
 ## 接口列表
 ### 1. 上传图片
 `POST /api/images/upload`
 上传单张或多张图片。字段 `image` 传图片；仍兼容 `file`、`files`。存入 `images/`。

  -H "Auth-Token: YOUR_TOKEN" \
  -F "image=@./demo.png"
 ```
 ### 2. 获取图片列表
 `GET /api/images`
 分页列出图库。`limit` 默认 20、最大 100。
 ```bash
 curl "https://admin.example.com/api/images?limit=20&page=1" \
  -H "Auth-Token: YOUR_TOKEN"
 ```
 ### 3. 搜索图片
 `GET /api/images/search`
 按文件名或路径关键词搜索，参数 `q` 必填。
 ```bash
 curl "https://admin.example.com/api/images/search?q=demo&limit=20&page=1" \
  -H "Auth-Token: YOUR_TOKEN"
 ```
 ### 4. 删除图片
 `DELETE /api/images`
 通过 `key` 删除单张，`key` 为存储路径（如 `images/2026/08/xxx.webp`）。
 ```bash
 curl -X DELETE "https://admin.example.com/api/images?key=images/2026/08/xxxx.webp" \
  -H "Auth-Token: YOUR_TOKEN"
 ```
 ### 5. 批量删除
 `POST /api/images/batch-delete`
 请求体 JSON：`{"keys":["images/2026/08/a.webp","images/2026/08/b.webp"]}`
 ```bash
 curl -X POST "https://admin.example.com/api/images/batch-delete" \
  -H "Auth-Token: YOUR_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{"keys":["images/2026/08/a.webp","images/2026/08/b.webp"]}'
 ```
 ## 错误格式
 REST 接口返回 JSON，含 `code` 与 `message`（如 `UNAUTHORIZED`、`FORBIDDEN`、`INVALID_REQUEST`）。Twikoo 端点使用 EasyImage 兼容 JSON 格式。
 ## 权限与可见范围
 - 普通用户 Token：列表/搜索/删除仅作用于自己的图片
 - 管理员 Token：可访问全部图片

 ---
 ## [1.2.2] — 2026-08-30
 > 升级后请**重启服务**使中间件与 API 生效。
 ### 双域名配置与 Host 隔离
 #### 修复
 | 问题 | 说明 |
 | ---- | ---- |
 | 管理域被误清空 | 设置页保存时，关闭双域名或仅改图片域可能把 `site_base_url` 写成空字符串，导致 UI 切回单域、管理域「消失」 |
 | 配置与生效 URL 混淆 | `GET /api/settings` 的 `siteBaseUrl` / `imageBaseUrl` 曾混入当前请求的 `origin`，设置页「当前生效」与数据库配置难以区分 |
 | 第三 Host 绕过隔离 | `pages.dev`、裸 IP、旧图片域等未纳入配置的 Host 此前不被中间件拦截，后台/API 可能仍可访问 |
 #### 改进
 **设置 API（`GET /api/settings`）**
 | 字段 | 含义 |
 | ---- | ---- |
 | `siteBaseUrl` / `imageBaseUrl` | **配置值**（DB → 环境变量），不含 request fallback |
 | `effectiveSiteBaseUrl` / `effectiveImageBaseUrl` | **直链生成用**，未配置时回退到当前请求 origin |
 | `runtime.currentOrigin` | 检测到的当前访问地址（仅展示，不写入配置） |
 | `runtime.hostRole` | `site` / `image` / `unknown` / `single` |
 **保存 API（`PATCH /api/settings`）**
 - 新增 body 字段 `domainSeparation`（`true` / `false`），显式表达是否启用双域名
 - `domainSeparation: true` 时网站域与图片域**均必填**，且主机名不能相同
 - `domainSeparation: false` 时允许清空网站域
 - 未传 `domainSeparation` 且双域名已配置时，**禁止**单独把 `siteBaseUrl` 置空
 **设置页 / 首次设置**
 - 表单回填配置值；「当前生效」显示 `effective*` 字段
 - 展示「检测到当前访问」地址，**不再**自动写入 `window.location.origin`
 - 提供「填入检测地址」按钮（用户主动点击才填）
 - 关闭双域名需确认弹窗
 - 双域名开启且 `hostRole === 'unknown'` 时显示反代绕过警告
 **Host 中间件**
 - 双域名开启时，非 site/image 的 Host **应用层一律 404**（所有 HTTP 方法）
 - 开发环境 `localhost` / `127.0.0.1` 例外，便于 `npm run dev`
 - 与 Nginx `default_server` **互补**，建议两层都配置
 #### 文档
 - 重写 [Cloudflare / CF 优选部署](./cloudflare-deployment.md)（精简结构、检查清单、双层防护）
 - 更新 [双域名分离](./domain-separation.md) 第三 Host 与应用层拦截说明
 - 新增本页 **更新日志**
 #### 升级说明
 - **无需**数据库迁移或 CLI 操作
 - 若管理域此前已被误清空：在 **设置** 中重新填写网站域，或设置环境变量 `SITE_BASE_URL` 后重启
 - 生产双域名部署：确认反代 `server_name` 与设置一致；建议保留 Nginx default server

 ## [1.2.1] — 2026-08-29
 ### 新增
 - 登录滑动拼图验证（缺口对齐）；验证与登录分两步
 - VitePress 文档站（`docs-site/`），部署至 GitHub Pages
 - `npm run docs:dev` / `docs:build` / `docs:preview`
 ### 修复
 - 统计页删除图片后图库不刷新
 - 分页跳转输入框在 `type="number"` 下无法跳转
 - 非首页路由下复制链接格式偏好不持久化
 - 滑动验证 UI：滑块垂直居中、缺口尺寸与滑块一致
 ### 改进
 - README 精简，详细说明迁入文档站
 - 双域名文档补充未知 Host 风险与 Cloudflare 部署说明
 ---
 ## [1.2.0] — 2026-08-28
 ### 变更
 - 图片统一存放在 `data/images/`；遗留 `blog/`、`twikoo/` 等并列目录需迁移
 ### 新增
 - CLI：`docker exec pichost migrate` / `migrate --apply`
 - 启动时自动同步图片索引（扫描磁盘、归一化遗留 key、清理孤儿记录）
 详见 [v1.2 迁移](./migration.md)。

 # Cloudflare / CF 优选部署说明
 PicHost 双域名模式下，应用根据请求 **Host**（及可信反代转发的 `X-Forwarded-Host`）区分**管理域**与**图片域**。使用 Cloudflare 橙云、优选线路、Workers 或 Pages 时，只要最终到达 PicHost 的 Host 身份不变，即可正常工作。
 > **一句话原则：** 网络线路可以改变，请求的域名身份不能改变 — `admin → admin`，`img → img`，不要 `img → admin`。
 基础概念见 [双域名分离](./domain-separation.md)；反代通用要求见 [反向代理](./reverse-proxy.md)。
 ---
 ## 快速检查清单
 部署或排错时，按顺序确认：
 | # | 检查项 | 期望 |
 | - | ------ | ---- |
 | 1 | 浏览器地址栏域名 | `admin.*` 或 `img.*`，不要用 IP / `pages.dev` 混用 |
 | 2 | 中间是否经过 Pages / Worker | 图片域**不得** `fetch(admin…)` |
 | 3 | 反代 upstream | 两个域名均指向 `http://127.0.0.1:6892` |
 | 4 | Nginx `proxy_set_header Host` | `$host`（保持客户端域名） |
 | 5 | PicHost 设置 | `SITE_BASE_URL` / `IMAGE_BASE_URL` 与 `server_name` 一致 |
 | 6 | 端口 `6892` | 仅本机或内网反代可达，不对公网裸露 |
 ---
 ## 推荐拓扑
 两个域名经 Cloudflare（橙云）后，**各自独立**反代到同一 PicHost 实例：
 ```mermaid
 flowchart TB
  internet[Internet]
  cf[Cloudflare 橙云]
  admin[admin.example.com]
  img[img.example.com]
  panel[1Panel / Nginx]
  app[PicHost :6892]
  internet --> cf
  cf --> admin
  cf --> img
  admin --> panel
  img --> panel
  panel --> app
 ```
 ```env
 SITE_BASE_URL=https://admin.example.com
 IMAGE_BASE_URL=https://img.example.com
 ```
 ```text
 admin.example.com → http://127.0.0.1:6892
 img.example.com   → http://127.0.0.1:6892
 ```
 不需要为「前端 / 后端 / 图片」开不同端口；一个 PicHost 实例、一个内部端口（默认 `6892`）即可。
 ### 管理域 ≠ 前端域名
 | 域名 | 用途 |
 | ---- | ---- |
 | `admin.example.com` | 后台、登录、设置、图库、API、上传 |
 | `img.example.com` | 图片直链、外链、CDN 分发 |
 更准确的说法是**管理域 / 图片域**，而非「前端 / 后端」。PicHost 生产环境也**不需要** `前端 :3000 + 后端 :6892` 这种拆分。
 ---
 ## Cloudflare 橙云与 CF 优选
 **橙云（DNS Proxied）** 是正常且推荐的方式：
 ```text
 admin.example.com、img.example.com
  A / CNAME → 源站 → Proxied
 ```
 用户访问 `admin.example.com` 时，PicHost 应收到 `Host: admin.example.com`；访问 `img.example.com` 时应收到 `Host: img.example.com`。
 **CF 优选**（优选 IP、优选域名、边缘入口）同样可用。优选可以改变用户到 Cloudflare 边缘的路径，但**不能**把图片域的回源身份变成管理域。两个域名应保持平行、独立的回源链：
 ```text
 admin → CF → admin.example.com → 源站 → PicHost
 img   → CF → img.example.com   → 源站 → PicHost
 ```
 ---
 ## 六、典型错误拓扑
 以下方案会破坏 Host 隔离，即使浏览器地址栏仍显示图片域：
 ### ❌ 错误 1：图片域 fetch 到管理域
 ```mermaid
 flowchart LR
  user[用户 img.example.com]
  worker[Pages / Worker]
  admin[fetch admin.example.com]
  app[PicHost]
  user --> worker --> admin --> app
 ```
 最后一跳 Host 变成 `admin.example.com`，PicHost 会认为这是管理域 — `https://img.example.com/` 可能看到后台。这是 **Host 被改写**，不是缓存问题。
 ### ❌ 错误 2：优选回源到管理域
 ```text
 img.example.com → 优选域名 → admin.example.com → 源站
 ```
 即使只为改善线路，只要 upstream 使用管理域，图片域隔离即失效。
 ### ❌ 错误 3：公网直接暴露 6892
 ```text
 任意域名 / IP:6892 → PicHost
 ```
 用户可绕开 Cloudflare 与 Nginx 的 `server_name` 限制。`6892` 应仅允许 `127.0.0.1` 或内网反代访问。
 ### ✅ 正确做法
 ```text
 admin → admin → PicHost
 img   → img   → PicHost
 ```
 **不要** Pages / Workers **整站反代** PicHost（会多出 `pages.dev` / `workers.dev` 等第三入口）。PicHost 依赖 `node-server`、SQLite、`sharp` 与本地 `data/`，**不能**作为 Node 应用直接部署到 Pages/Workers；应用本体继续 Docker/VPS 部署，CF 侧用橙云 DNS + 可选 R2 即可。
 ---
 ## Workers / Pages 使用建议
 若只需改响应头、鉴权、防盗链、日志或缓存，且源站仍是自己的 PicHost：
 | 推荐 | 不推荐 |
 | ---- | ------ |
 | `img.example.com` → **Worker Route** → 原 `img` 源站 | `img` → Worker → `fetch(admin.example.com)` |
 Cloudflare 对已有外部源站的场景更推荐 [Routes](https://developers.cloudflare.com/workers/configuration/routing/routes/)（在现有 proxied 域名与源站之前运行），而非用 [Custom Domain](https://developers.cloudflare.com/workers/configuration/routing/custom-domains/) 把 Worker 当作跨域 fetch 的中转。
 Worker 中若出现：
 ```js
 fetch(`https://admin.example.com${url.pathname}`)
 ```
 即基本可确定隔离被破坏。
 ---
 ## Nginx / 1Panel 配置
 两个 `server` 块，upstream 相同，**关键行**是 `proxy_set_header Host $host;`：
 ```nginx
 server {
    server_name admin.example.com;
    location / {
        proxy_pass http://127.0.0.1:6892;
        proxy_set_header Host $host;
        proxy_set_header X-Forwarded-Proto $scheme;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        client_max_body_size 12m;
    }
 }
 server {
    server_name img.example.com;
    location / {
        proxy_pass http://127.0.0.1:6892;
        proxy_set_header Host $host;
        proxy_set_header X-Forwarded-Proto $scheme;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    }
 }
 # 拒绝裸 IP 与未配置域名（强烈建议）
 server {
    listen 80 default_server;
    listen 443 ssl default_server;
    server_name _;
    return 444;
 }
 ```
 橙云部署时，源站防火墙建议**仅放行 [Cloudflare IP 段](https://www.cloudflare.com/ips/)**，避免绕过 CDN 直连。
 ---
 ## 双层 Host 防护
 生产环境建议反代层与应用层**互补**，而非二选一：
 | 层级 | 作用 |
 | ---- | ---- |
 | **Nginx default server** | 拒绝裸 IP、`pages.dev` 等未在 `server_name` 中声明的 Host |
 | **PicHost 中间件（v1.2.x+）** | 双域名开启时，非 site/image 的 Host 应用层返回 404（开发环境 `localhost` / `127.0.0.1` 例外） |
 即使应用层已拦截第三 Host，仍建议在反代配置 default server — 减少无效流量到达 PicHost。
 ---
 ## X-Forwarded-Host 说明
 PicHost 在反代场景会参考 `X-Forwarded-Host` 识别请求域名，但**不能无条件信任**该 Header（客户端可伪造）。因此：
 - 不要让 `6892` 对公网裸露
 - 确保只有可信反代能到达应用
 - 首选方案仍是让 `Host` 从第一跳起就保持正确
 ---
 ## 排查：图片域能看到后台？
 **先查反代链，不要先清 CF 缓存。**
 缓存问题通常表现为旧 JS/CSS/图片或偶发 404；若图片域能**稳定**访问 `/`、`/login`、`/settings`，几乎都是 Host 被改写。
 ```text
 ① 浏览器实际域名？
 ② 是否经过 Pages / Worker / 优选反代？
 ③ 代理最终 fetch 的 URL？
 ④ 是否 fetch 到 admin.example.com？
 ⑤ 1Panel / PicHost 最终收到的 Host？
 ```

 PicHost 支持通过环境变量（Docker / `.env`）与后台 **设置** 页配置。管理员在 **设置与偏好**（`/settings`）左侧切换 **基础设置**、**域名与路径**、**访问控制**、**操作日志**；多数项 **SQLite 优先**；部分项环境变量可覆盖或锁定后台编辑。
 ## 优先级总览

 - 别名：`NUXT_API_UPLOAD_TOKEN`
 ### `ALLOWED_REFERER_HOSTS`
 防盗链白名单，逗号分隔域名。自身域名自动放行。可选；不填可在设置页配置。若环境变量有值且 SQLite 未存，则使用环境变量。
 ### `SITE_BASE_URL` / `IMAGE_BASE_URL`
 - **网站域名**：管理后台、API、Twikoo 上传入口
 - **图片域名**：复制链接与直链使用的公网地址
 双域名分离需两者主机名不同，详见 [双域名分离](./domain-separation.md) 与 [Cloudflare / CF 优选部署](./cloudflare-deployment.md)。填写后须与反代 `server_name` 一致；**勿**通过 `localhost`、IP 或未配置的域名访问生产后台。
 在后台 **设置** 中保存时须显式勾选「启用后台与图片域名分离」，并同时填写两个域名；关闭双域名会清除网站域配置（需确认）。设置 API 返回的配置值与「当前生效」直链地址已分离，详见 [更新日志](./changelog.md#1-2-2-2026-08-30)。
 ### `HIDE_FOLDER_IN_URL`
 `true` 时使用简短图片链接（仅域名 + 文件名，如 `img.example.com/a8K3xP.webp`）；`false` 时保留日期或自定义目录（如 `img.example.com/2026/08/a8K3xP.webp`）。对外 URL **不会** 暴露内部 `images/` 前缀；旧版含 `images/` 的直链仍兼容。
 ### `STORAGE_USE_DATE_PATH` / `STORAGE_LAYOUT`
 - `STORAGE_USE_DATE_PATH=true`（默认）或 `STORAGE_LAYOUT=date`：新图保存为 `images/年/月/随机ID.webp`
 - `false` 或 `STORAGE_LAYOUT=flat`：保存为 `images/随机ID.webp`
 也可在设置页切换。
 ### `DATA_DIR`
 图片与 SQLite 根目录。默认 `./data`，容器内为 `/data`。
 ### `WEBP_QUALITY`
 服务端 WebP 压缩质量 1–100，默认 **80**。
 ### `AUTO_DELETE_DAYS`
 全局自动删除超过 N 天的图片，`0` 表示关闭。启用后仅影响**之后新上传**的图片（与按用户策略一致）。也可在设置页配置。
 ### `DEV_BYPASS_ACCESS`
 仅本地开发：`true` 绕过登录验证。生产环境勿用。
 ### 存储后端（可选）
 管理员通常在 **存储** 页添加后端；也可用环境变量引导（如 `STORAGE_BACKEND=s3` 与 `S3_*`）。详见 [存储](./storage.md)。
 ## Docker Compose 示例
 ```yaml

 # 双域名分离 · 推荐部署架构
 启用「后台与图片域名分离」后，管理后台、API 与图片直链使用不同域名。PicHost 通过 **Host 中间件** 双向隔离：
 - **网站域**：后台、API、上传；**禁止**直链出图（图片路径返回 404）
 - **图片域**：仅放行图片路径；其余请求返回 404
 ## 架构说明
 **单 Docker 实例 + 两个域名**，均可 **全量反代** 到 `6892`（隔离由 PicHost 中间件负责，无需在 Nginx 层拆分路径）。
 | 域名 | 用途 |
 | ---- | ---- |
 | `admin.example.com` | 管理后台、API、Twikoo 上传 |
 | `pic.example.com` | 图片直链（中间件拦截非图片路径） |
 初始化时在 `/setup` 或后台 **设置** 中填写：
 - **网站域名**：`https://admin.example.com`
 - **图片域名**：`https://pic.example.com`
 首次设置与系统设置**不会**自动把当前浏览器地址写入网站域；可手动填写或点击「填入检测地址」。关闭双域名需确认，且会清除网站域配置。保存时 API 会收到 `domainSeparation: true/false` 字段。详见 [更新日志](./changelog.md#1-2-2-2026-08-30)。
 ## Nginx 示例
 ```nginx
 # admin.example.com — 后台 + API（不出图，直链请走图片域）
 server {
  server_name admin.example.com;
  location / {
    proxy_pass http://127.0.0.1:6892;
    proxy_set_header Host $host;
    proxy_set_header X-Forwarded-Proto $scheme;
    client_max_body_size 12m;
  }
 }
 # pic.example.com — 同样全量反代；PicHost 中间件会拦截非图片路径
 server {
  server_name pic.example.com;
  location / {
    proxy_pass http://127.0.0.1:6892;
    proxy_set_header Host $host;
    proxy_set_header X-Forwarded-Proto $scheme;
  }
 }
 # 默认 server：拒绝裸 IP、未配置域名等其它 Host（生产环境强烈建议）
 server {
  listen 443 ssl default_server;
  listen 80 default_server;
  server_name _;
  return 444;
 }
 ```
 > Caddy、NPM（Nginx Proxy Manager）等工具同理：两个域名均反代到 `http://<主机>:6892`，并保留 `Host` 与 `X-Forwarded-Proto` 头。
 ## 安全与注意事项
 ### 中间件隔离与第三 Host
 PicHost 根据请求 **Host**（反代会转发为 `X-Forwarded-Host`，应用会一并识别）判断当前是网站域还是图片域：
 - **图片域**：非图片路径（如 `/`、`/settings`）→ 404
 - **网站域**：图片直链路径（如 `/images/...`）→ 404
 - **未配置的第三 Host**（如 `*.pages.dev`、裸 IP、旧图片域）：**v1.2.x 起应用层一律 404**（开发环境 `localhost` / `127.0.0.1` 例外，便于 `npm run dev`）
 这与域名是否带 `-`、长短无关；此前版本对第三 Host 不拦截，需依赖反代 default server 封堵。
 **生产环境建议：**
 1. 反代层仅为网站域、图片域配置 `server_name`，并增加 **default server** 拒绝其它 Host 与裸 IP（见上方 Nginx 示例，与应用层拦截互补）
 2. 使用 Cloudflare **橙云** 时，源站防火墙 **仅放行 [Cloudflare IP 段](https://www.cloudflare.com/ips/)**，避免绕过 CDN 直连源站
 3. **仅使用** 设置中的网站域名登录后台，不要用 `localhost`、IP 或未配置的域名混用
 4. **不要** 用 Cloudflare Pages / Workers 对 PicHost **整站反代**（会多出 `pages.dev` / `workers.dev` 等第三入口；`IMAGE_BASE_URL` 可填 CDN 公网地址，但应用本体应 Docker/VPS 部署）
 5. 若必须在边缘做反代，须保留客户端 **`Host` 或 `X-Forwarded-Host`**，否则 Host 隔离会失效
 6. PicHost **不能** 作为 Node 应用直接部署到 Pages/Workers（依赖 `node-server`、SQLite、`sharp` 与本地 `data/`）；应用请继续 Docker/VPS 部署，CF 侧用橙云 DNS + 可选 R2 存储即可
 ### Cloudflare 橙云（含 DNS 优选）
 完整说明见专章：[Cloudflare / CF 优选部署](./cloudflare-deployment.md)。
 **推荐：** `admin.example.com` 与 `pic.example.com` 均 **DNS Proxied（橙云）** → 源站 Nginx / 1Panel 反代 `6892`，SSL 模式 **Full (strict)**。
 | 能力 | 说明 |
 | ---- | ---- |
 | 橙云 CDN | 与 PicHost 双域名兼容；回源须保留 `Host`、`X-Forwarded-Proto` |
 | DNS 优选 | 仅改变用户连到 CF 边缘的 IP；**admin → admin、img → img** 的回源身份不能变 |
 | R2 对象存储 | 在 **存储** 页添加 R2 后端即可，与是否橙云无关 |
 | `cloudflare` Git 分支 | R2 专用部署线，仍是 Docker 运行，**不是** Workers 托管 |
 **勿混淆：** CF 控制台「创建 Worker」并连接本仓库 **无法** 直接部署 PicHost；`npm run build` + `wrangler deploy` 与当前 `node-server` 预设不兼容。
 **勿用 Pages/Worker 把图片域 `fetch` 到管理域** — 会破坏 Host 隔离（详见 [Cloudflare 部署说明 · 典型错误拓扑](./cloudflare-deployment.md#六典型错误拓扑)）。
 反代与源站加固详见 [反向代理](./reverse-proxy.md#cloudflare-橙云)。
 ## 飞牛 NAS · Lucky 反向代理
 在 [Lucky](https://github.com/gdy666/lucky) 中为两个域名各建一条 **反向代理** 规则，**前端地址** 填公网域名，**后端地址** 填 PicHost 所在内网 IP 与端口（如 `http://192.168.8.3:6892`）。
 **网站域名（管理后台）**
 | 项 | 示例值 |
 | -- | ------ |
 | 服务类型 | 反向代理 |
 | 前端地址 | `admin.pichost.com` |
 | 后端地址 | `http://192.168.8.3:6892` |
 **图片域名**
 | 项 | 示例值 |
 | -- | ------ |
 | 服务类型 | 反向代理 |
 | 前端地址 | `image.pichost.com` |
 | 后端地址 | `http://192.168.8.3:6892` |
 两条规则的后端地址相同即可；域名分离与路径隔离由 PicHost 根据请求 `Host` 自动处理。
 ## 环境变量（可选）
 除 Web 设置外，也可在 `.env` 或 Docker 环境中配置：
 ```env
 SITE_BASE_URL=https://admin.example.com
 IMAGE_BASE_URL=https://pic.example.com
 ```
 详见 [环境变量](./configuration.md)。
 ## 本地测试（Windows / macOS）
 ### 1. 修改 hosts
 ```text
 127.0.0.1 admin.pichost.test
 127.0.0.1 pic.pichost.test
 ```
 建议使用 `.test` 后缀，避免 `.local` 在部分系统上与 mDNS 冲突。
 ### 2. 启动开发服务
 ```bash
 npm run dev
 ```
 项目已默认绑定 `127.0.0.1:3000`（与 hosts 的 IPv4 一致）。若曾出现 `ping` 通但浏览器连不上，多半是 dev 只监听了 IPv6 `::1`。
 ### 3. 填写双域名
 | 项 | 示例 |
 | -- | ---- |
 | 网站域名 | `http://admin.pichost.test:3000` |
 | 图片域名 | `http://pic.pichost.test:3000` |
 **后台请始终用网站域名打开**，不要用 `localhost`（Cookie 与 Host 不一致）。
 ### 4. 预期结果
 | 地址 | 预期 |
 | ---- | ---- |
 | `http://admin.pichost.test:3000/` | 正常进入后台 |
 | `http://admin.pichost.test:3000/images/...` 或 `/2026/08/xxx.webp` | **404**（请用图片域直链） |
 | `http://pic.pichost.test:3000/` | **404**（正常，图片域不提供后台） |
 | `http://pic.pichost.test:3000/images/...` | 能出图 |
 | `http://localhost:3000/` 或 `http://127.0.0.1:3000/` | **能打开后台**（开发环境例外；生产须用反代封禁未配置 Host） |
 上传一张图后，复制链接应指向 `pic.pichost.test` 域名；在后台图库中缩略图也应能正常显示。
 ## 相关说明
 - 两个域名 **主机名不能相同**（可同机、不同子域）
 - 设置里的网站域 / 图片域须与反代 `server_name` **完全一致**（含是否带 `www`）
 - 图片域无需单独部署静态目录；与 EasyImages 等不同，PicHost 在应用内完成隔离
 - 单域名部署可不启用分离，仅配置 `IMAGE_BASE_URL` 或使用默认当前访问域名
 - 配置了 Referer 防盗链时，网站域与图片域会自动加入白名单，无需手写两个域名
 单域名反代要点见 [反向代理](./reverse-proxy.md)。

 # 常见问题
 ## 忘记管理员密码怎么办？
 能执行 `docker exec` 时：
 ```bash
 docker exec pichost reset-password
 # 或指定用户名
 docker exec pichost reset-password 用户名
 ```
 本地：`npm run reset-password`。详见 [快速开始](./getting-started.md#忘记密码)。
 ## 为什么后台无法重新生成 API Token？
 若设置了环境变量 `API_UPLOAD_TOKEN`，Token 由环境变量 **锁定**，需修改 env 并 **重启服务**。见 [环境变量](./configuration.md#api-upload-token)。
 ## 图片外链显示「盗链」或无法加载？
 检查 **防盗链白名单**（`ALLOWED_REFERER_HOSTS` 或设置页）。引用图片的站点域名需在白名单中；PicHost 自身域名与双域名场景下的网站域、图片域会自动放行。
 ## 双域名下为什么用 pages.dev / workers.dev / IP 也能进后台？
 **v1.2.2 起：** 双域名开启时，PicHost 中间件会对**未配置的网站域、图片域之外**的 Host 返回 **404**（开发环境 `localhost` / `127.0.0.1` 例外）。详见 [更新日志](./changelog.md#1-2-2-2026-08-30)。
 若仍能访问，常见原因：
 1. **未启用双域名**（仅配置了图片域、网站域为空）— 隔离与第三 Host 拦截均不生效
 2. **反代把 Host 改成管理域** — 例如 Pages/Worker 对图片域 `fetch(admin…)`，PicHost 看到的是管理域
 3. **源站裸暴露 `6892`** — 绕过 Cloudflare 与 Nginx `server_name`
 处理：在设置中正确配置双域名；反代加 default server；橙云时源站只放行 CF IP；勿用 Pages/Workers 整站反代。详见 [双域名分离](./domain-separation.md#中间件隔离与第三-host)、[Cloudflare 部署](./cloudflare-deployment.md) 与 [更新日志](./changelog.md#1-2-2-2026-08-30)。
 ## 能把 PicHost 部署到 Cloudflare Workers / Pages 吗？
 **不能（现状）。** 项目使用 `node-server`、SQLite、`sharp` 与本地 `data/`，需 Docker / VPS。CF 控制台「从 Git 创建 Worker」连本仓库会部署失败。
 推荐：源站跑 PicHost，CF 用 **橙云 DNS**（含优选）+ 可选 **R2 存储**；不要用 Pages/Workers 反代整站。
 ## 双域名下后台能打开但缩略图裂图？
 - 确认 **图片域名** 配置正确且反代到同一实例
 - 后台请用 **网站域名** 打开，不要用 `localhost` 混用
 - 见 [双域名分离](./domain-separation.md)
 ## 升级 v1.2 后图库有删不掉的记录？
 可能是 **孤儿索引**（有记录无文件）。重启后启动同步会自动清理；也可手动删除仅索引项。见 [v1.2 迁移](./migration.md#第二步启动时自动同步索引)。
 ## 遗留 `data/blog/` 目录还要吗？
 执行 `migrate --apply` 后文件已迁入 `data/images/blog/`。若原目录只剩空壳或非图片文件，可自行备份后删除；迁移脚本不会删除仍含非图片文件的目录。
 ## 只用对象存储需要跑 migrate 吗？
 不需要。图片在桶内时跳过 CLI；启动同步主要面向本地 `data/images/` 磁盘扫描。
 ## 如何替换博客里的旧图片 URL？
 使用 `data/mapping.json`（`migrate` 预览时生成）批量替换旧 key。注意映射的是 **存储 key**，不是完整旧站 URL。见 [迁移指南](./migration.md#外链与直链)。
 ## 开发时如何跳过登录？
 `DEV_BYPASS_ACCESS=true`（仅本地，勿用于生产）。正常流程请访问 `/setup` 创建管理员。
 ## 文档与仓库 README 哪个为准？
 **本 VitePress 文档站** 为完整用户指南；README 保留摘要与快速开始。在线地址：<https://o96u.github.io/PicHost/>
 ## GitHub 仓库 About 怎么写？
 **main** 分支建议：
 - **Description**：`Lightweight self-hosted image hosting — Docker, multi-user, gallery & API, local disk or S3-compatible storage.`
 - **Website**：`https://o96u.github.io/PicHost/`（文档站，非图床演示）
 勿写「部署在 Cloudflare Pages/Workers」—— PicHost 应用跑在 Docker/VPS；**cloudflare** 分支在线演示为 [pic.roven.cc](https://pic.roven.cc)。
