 # Changelog
 ## 4.9.19 - 2026-07-31
 - 修复 Docker / Node 自托管下 `/api/user/sync` 与 `/api/user/config` 无法从 `process.env` 读取 Upstash 凭据、持续返回 500 的问题；Redis 客户端改为按请求环境惰性创建，未配置同步时明确返回 503（#226 / PR #227）。
 - 云端恢复和历史/收藏列表渲染会过滤缺少 `videoId`、`source`、`title` 或有效 `episodeIndex` 的损坏记录；全部记录无效时正常显示空状态，不再让账户首页因渲染异常永久崩溃（#228 / PR #229）。
 - 豆瓣图片代理在 `imgN.doubanio.com` 线路不可达时按 `img9`、`img3`、`img2` 镜像回退，并保留最后一次上游响应状态，修复境外部署海报批量 500（PR #230）。
 - 新增同步记录和豆瓣镜像回退回归测试；真实 Next.js standalone + Upstash REST 兼容环境下的托管登录、同步读写与配置读写均验证通过。
 ## 4.9.18 - 2026-07-29
 - 修复移动端播放器控制栏在窄屏下被裁切、最右侧“系统全屏”按钮不可见的问题（#224）。
 - 控制栏现在根据播放器自身宽度进入紧凑布局：隐藏窄屏音量入口、压缩间距，并在极窄播放器中只显示当前播放时间；画中画、AirPlay、Cast、网页全屏与系统全屏按钮继续保留。
 - 新增移动端播放器控制栏回归测试，锁定两个全屏入口在窄屏下不会再次被可选播放按钮挤出可视区。
 ## 4.9.17 - 2026-07-29
 - 新增基于主内容时长残差的组合式 M3U8 插播检测；残差只作为辅助证据，单个 `.033/.333/.867` 等合法分片不再被直接删除。
 - 重复时长指纹恢复大内容块保护并限制出现比例，避免固定 GOP、等长章节或重复正片结构被整块误删。
 - 跨源同路径检测同时比较来源域名与文件名模式，在增强 Multi-CDN 插播识别的同时保留合法 CDN 切换的保护条件。
 - 安全审查后未启用基于 `new Function` 的动态 JS/TS 执行和公开脚本 API；该实现不是沙盒，且无法防止任意代码执行或主线程死循环。
 - 广告检测器拆分为解析、主模式、重复指纹、时长网格与评分模块，并补充误删回归测试。
 - Next.js 与配套 ESLint 配置升级至最新稳定版 16.2.12，消除 16.2.10 的多项框架级高风险公告；上游固定的 PostCSS/sharp 审计项仍等待官方稳定修复。
 ## 4.9.16 - 2026-07-27
 - 修复窗口宽度变化后右侧“历史播放记录”浮动按钮停留在原位置、无法继续贴靠右边缘的问题。
 - 收藏与历史浮动按钮现在会在窗口尺寸变化时保持各自的左右锚点；已拖拽的按钮按可拖拽区域比例保留位置。
 - 新增浮动按钮定位与窗口缩放回归测试。
 ## 4.9.15 - 2026-07-25
 - 修复播放页点击选集“排序”导致播放器闪烁/重播：`usePlayerSettings` 在非播放器核心设置变化时复用快照引用，避免 HLS 实例被销毁重建。
 - 播放页布局对齐：视口控制移到内容区顶部，播放器与选集列顶部对齐；网页全屏按钮改用更贴合的框式图标。
 - 选集支持网格排版 + 分段翻页（每页 50 集），长剧集可快速跳转；仍可切回列表模式。
 - 源列表、视频详情与搜索卡片在封面缺失或加载失败时使用 `/placeholder-poster.svg` 占位图。
 - 合并并加固 PR #219 广告检测升级：新增 M3U8 分片时长指纹去重，同时保留代理 URL 解包、interstitial 元数据剥离与关键词归一化。
 - 修复 Android TV 9 / 旧 WebView 白屏：客户端静态资源目标从 `chrome83` 降到 `chrome69`，彻底去掉 `??` / `?.` / 逻辑赋值，兼容 Amlogic 等 Android 9 系统 WebView。
 - 新增广告检测、播放器设置快照与 WebView 69 回归测试。
 ## 4.9.13 - 2026-07-13
 - 修复慢视频源超过 3 秒未返回时，前端提前结束搜索并错误显示“未找到结果”的问题；搜索现在等待服务端明确完成或响应流真正关闭。
 - 实时延迟探测现在使用视频源的真实 `baseUrl`，不再把源 ID 当成 URL；`HEAD` 失败后的 `GET` 探测独立计时，避免把前一次失败耗时叠加为虚高延迟。
 - 延迟探测改为最多 4 路并发并在上一轮结束后再调度下一轮，避免 Docker 自托管实例因慢源产生重叠探测请求。
 - 搜索请求取消或超时后不再继续重试，并清理级联 AbortSignal 监听器；新增慢源、探测回退、并发上限和取消重试回归测试。
 ## 4.9.12 - 2026-07-12
 - 修复窄屏导航栏隐藏整个用户区域、导致登录用户无法退出的问题；退出按钮现在在所有视口宽度下保持可见，用户身份详情仍在桌面端显示。
 - 高级模式设置页复用统一的账户管理组件，恢复当前账户信息、退出登录以及超级管理员的账户新增、编辑和删除入口。
 - 新增账户入口回归测试，防止响应式样式或高级模式设置页再次移除关键认证操作。
 ## 4.9.11 - 2026-07-09
 - 修复登录成功后仍停留在登录页、刷新后又要求登录的循环问题。
 - `PasswordGate` 登录成功后会直接解除客户端锁定，不再依赖整页刷新；服务端 session 存在但本地镜像缺失时也会直接补齐会话并进入应用。
 - 服务端 session cookie 的 `Secure` 属性改为按实际请求协议和 `x-forwarded-proto` 判断，避免 Docker / HTTP 自托管生产模式下浏览器拒收登录 cookie。
 - 新增登录 gate 状态决策和 session cookie 协议判断回归测试。
 ## 4.9.10 - 2026-07-09
 - 从首页移除硬编码的快捷搜索区，不再显示“内容分类”“电影类型”“年份”三组按钮。
 - 标签管理入口和首页推荐区现在直接从内容类型切换与后端标签列表开始，避免顶部快捷搜索继续占用空间。
 - 更新标签管理视图回归测试，锁定首页不再引用 `CategoryQuickSearch`。
 ## 4.9.9 - 2026-07-09
 - 修复首页管理标签入口混入快捷搜索流程的问题，打开管理模式后不再显示“内容分类”“电影类型”“年份”等搜索快捷项。
 - 管理标签时隐藏电影/电视剧切换和推荐内容网格，让“完成 / 恢复默认 / 添加标签 / 标签列表”成为当前视图主体。
 - 标签管理列表改为可换行 chip 布局，并在管理模式下使用矩形拖拽排序策略，避免标签区域被横向滚动行挤压。
 - 新增标签管理视图回归测试，防止管理入口再次退化为搜索筛选界面。
 ## 4.9.8 - 2026-07-09
 - 修复登录完成跳转后 Network 面板出现 `/api/user/config` 和 `/api/user/sync` 两个 400 请求的问题。
 - `AutoSync` 改为在 `PasswordGate` 确认服务端 session 并放行页面内容后再挂载，避免本地旧 session 早于服务端 cookie 校验触发云同步。
 - 用户配置和云同步 API 在未认证时返回 `401 Authentication required`，不再使用 `400 Missing profileId` 表达会话缺失。
 - 新增未认证响应回归测试，锁定受保护同步接口的状态码语义。
 ## 4.9.7 - 2026-07-09
 - 修复 Android TV / 小米电视旧 WebView 83 打开站点后白屏的问题。
 - Next.js 构建后的浏览器静态 JS 会额外转译到 `chrome83`，避免 `??=`、`||=`、`&&=` 等逻辑赋值语法让旧 WebView 在解析阶段直接失败。
 - Cloudflare Pages 输出目录同样会执行兼容性转译，确保 Docker/Node 自托管和 Cloudflare Pages 部署的浏览器资产一致。
 - 新增 WebView 83 静态资源回归测试，防止不兼容语法重新进入构建产物。
 ## 4.9.6 - 2026-07-09
 - 修复移动端 Safari 网页横屏时弹幕字体被异常拉伸或压缩的问题。
 - 弹幕画布改为优先读取未受 CSS transform 影响的布局尺寸，避免强制横屏旋转时使用横竖互换的 bounding box。
 - 横竖屏、窗口尺寸和 `visualViewport` 变化后会重新同步画布 backing store，并按新尺寸重排活跃弹幕。
 - 新增弹幕画布尺寸工具测试，覆盖 CSS transform 造成视觉尺寸与布局尺寸不一致的场景。
 ## 4.9.5 - 2026-07-09
 - Vercel Analytics 现在只会在真实 Vercel 部署中注入，Docker、自托管和 Cloudflare Pages 不再请求 `/_vercel/insights/script.js`。
 - Cloudflare 部署环境判定优先于 Vercel 风格环境变量，避免适配器环境被误判为 Vercel。
 - 新增部署环境单元测试，覆盖自托管、Vercel、Cloudflare 和混合环境变量场景。
 ## 4.9.4 - 2026-07-08
 - 设置页的代理播放区域显示内置 `/api/proxy` 端点和部署限制，明确该功能不是第三方 HTTP/SOCKS 代理服务器配置。
 - 新增 `ALLOW_LAN_ACCESS` 环境变量：开启后 `npm run dev` / `npm run start` 会绑定 `0.0.0.0`，开发模式会放行常见内网 IPv4 来源。
 - 新增 `LAN_ALLOWED_DEV_ORIGINS`，允许自定义 Next.js 开发模式的额外来源主机。
 - README 补充局域网访问和内置媒体代理说明，并同步修正 Docker hostname 注释。
 ## 4.9.3 - 2026-04-15
 - 新增 Redis 托管账户模式：支持用户名密码登录、超级管理员账户 CRUD、权限编辑和密码重置。
 - 认证改为服务端签名 HTTP-only 会话 Cookie，`/api/user/config` 与 `/api/user/sync` 不再信任客户端自报 `profileId`。
 - 播放页线路列表补齐剩余问题：分辨率探测会按当前集数探测并缓存，打开线路列表时会自动定位当前线路，必要时自动展开隐藏项。
 - 仓库补充了与新认证和线路列表逻辑对应的单元测试，并修正了本地 `eslint` 版本与 Next.js 规则链不兼容的问题。
 ## 4.9.2 - 2026-04-12
 - 设置页首次自动检查更新时不再让“检查更新”按钮自己持续转圈。
 - 移除会反复闪烁的“正在整理结果”提示，避免用户误以为页面异常。
 - 手动点击“检查更新”时才显示按钮转圈，状态反馈与用户操作保持一致。
 ## 4.9.1 - 2026-04-12
 - 移除仅支持 Node.js 的 `/api/site-icon` 路由，避免 `next-on-pages` 因非 Edge 路由中止构建。
 - 站点图标改为由服务端布局直接解析，导航栏和播放器页继续显示运行时配置的图标。
 - PWA manifest 回退为静态图标，确保 Cloudflare Pages、Docker 和本地构建链路一致可用。
 ## 4.9.0 - 2026-04-12
 - 设置页新增“版本与更新”卡片，直接显示当前版本、最近更新内容和检查结果。
 - 新增手动“检查更新”按钮，会对比 GitHub `main` 分支上的最新版本元数据。
 - 仓库新增更新日志文件，方便在项目内查看当前版本和更新说明。
 ## 4.8.3 - 2026-04-12
 - 站点图标改为支持运行时配置，Docker 镜像无需重新构建即可替换。
 - 扩展播放器默认视口，减少桌面端播放器黑边。
 - 修复 Android WebView 中 Cast SDK 判定以及全屏和画中画相关兼容性问题。

 ## 账户与访问控制
-KVideo 支持基于环境变量的账户认证系统，支持角色区分和细粒度权限控制。
+KVideo 现在支持两套认证模式：
-### 方式一：单管理员密码
+- **托管账户模式（推荐）**：配置 `AUTH_SECRET` + Upstash Redis 后，登录改为 **用户名 + 密码**，超级管理员可直接在设置页创建、修改、重置和删除账户。
 - **环境变量模式（兼容旧部署）**：未启用托管账户时，继续使用 `ADMIN_PASSWORD` / `ACCESS_PASSWORD` / `ACCOUNTS` 进行密码登录。
 ### 方式一：托管账户模式（推荐）
 启用条件：
 - 配置 `AUTH_SECRET`
 - 配置 `UPSTASH_REDIS_REST_URL`
 - 配置 `UPSTASH_REDIS_REST_TOKEN`
 - （可选）配置 `MANAGED_AUTH_ENABLED=true` 强制优先使用托管账户模式
 启用后：
 - 主登录页使用 **用户名 + 密码**
 - 服务端使用 HTTP-only 签名会话 Cookie 作为认证真源
 - 超级管理员可在设置页直接管理账户和权限
 - 配置同步、历史、收藏等跨设备数据会按登录账户自动隔离
 > **强制优先托管模式**：设置 `MANAGED_AUTH_ENABLED=true` 只会改变认证模式选择，不会跳过 `AUTH_SECRET` 和 Redis 检查。缺少 `AUTH_SECRET`、`UPSTASH_REDIS_REST_URL` 或 `UPSTASH_REDIS_REST_TOKEN` 时，托管账户模式仍不会启用。
 首次启用时，如果 Redis 里还没有账户，会自动使用 `ADMIN_PASSWORD` 和 `ACCOUNTS` 作为引导种子创建首批托管账户。

 ```bash
 docker run -d -p 3000:3000 \
  -v /path/to/icon.png:/app/custom/icon.png:ro \
  -e SITE_ICON_FILE=/app/custom/icon.png \

 **示例：**
 ```bash
 # 开发模式允许同局域网设备访问
 ALLOW_LAN_ACCESS=true npm run dev
 # 传统 Node.js 生产模式允许同局域网设备访问
 ALLOW_LAN_ACCESS=true npm run start
 # 追加自定义开发来源；Next.js 需要主机名，不要填写路径
 ALLOW_LAN_ACCESS=true LAN_ALLOWED_DEV_ORIGINS="kvideo.lan,192.168.50.10" npm run dev
 ```
 开启后访问地址通常是 `http://<当前设备内网 IP>:3000`。如果仍然无法访问，优先检查系统防火墙、路由器客户端隔离、端口映射、反向代理监听地址以及实际运行端口；这些不是 KVideo 前端代码可以绕过的问题。Docker 镜像已经在容器内绑定 `0.0.0.0`，是否能从局域网访问主要取决于 `-p` 端口映射和宿主机网络策略。
 ## 内置媒体代理说明
 设置页的“代理播放模式”使用的是当前 KVideo 部署内置的 `/api/proxy` 媒体转发端点，不是让用户填写第三方 HTTP/SOCKS 代理服务器。
 | 模式 | 行为 |
 |------|------|
 | 智能重试 | 优先直连，播放失败后自动切换到 `/api/proxy` |
 | 仅直连 | 不使用 `/api/proxy`，失败时直接报错 |
 | 总是代理 | 播放地址始终通过 `/api/proxy` 转发 |
 `/api/proxy?url=<encoded-video-url>` 只在 Docker 或传统 Node.js 自托管完整模式下启用。Vercel / Cloudflare 托管部署运行合规模式，会禁用外部媒体代理、热链转发和 IPTV 流中继；这种部署环境下设置页会显示仅支持直连播放。

 ## 部署合规说明
 Issue [#127](https://github.com/KuekHaoYang/KVideo/issues/127) 之后，仓库的公开部署策略做了调整，目的只有一个：避免把这个项目继续包装成“GitHub 账号直连第三方平台的一键导入仓库”。
 - 不再推荐任何 `Deploy with Vercel`、`Connect GitHub`、`Fork 后直接授权第三方读取仓库` 这一类 GitHub 直连导入流程。
 - Vercel / Cloudflare 托管部署现在默认运行在**合规模式**：自动关闭外部媒体代理、热链转发和 IPTV 流中继，仅保留直连播放路径。
 - 需要 `/api/proxy`、`/api/iptv/stream`、自定义 `User-Agent` / `Referer` 转发、IPTV 中继等能力时，请使用 Docker 或传统 Node.js 自托管。
 - 无论部署到哪里，都只应接入你有权使用、且允许当前部署环境访问的内容来源。
 - 相关政策请直接阅读官方原文：
  - [GitHub Terms of Service](https://docs.github.com/en/site-policy/github-terms/github-terms-of-service)

+#### 选项 1：Docker 部署（推荐，完整功能）
 [![Deploy with Vercel](https://vercel.com/button)](https://vercel.com/new/clone?repository-url=https://github.com/KuekHaoYang/KVideo)
 1. 点击上方按钮
 2. 连接你的 GitHub 账号
 3. Vercel 会自动检测 Next.js 项目并部署
 4. 几分钟后即可访问你自己的 KVideo 实例
 #### 选项 2：Cloudflare Pages 部署 (推荐)
 此方法完全免费且速度极快，是部署本项目的最佳选择。
 1. **Fork 本仓库**：首先将项目 Fork 到你的 GitHub 账户。
 2. **创建项目**：
   - 点击访问 [**Cloudflare Pages - Connect Git**](https://dash.cloudflare.com/?to=/:account/pages/new/provider/github)。
   - 如果未连接 GitHub，请点击 **Connect GitHub**；若已连接，直接选择你刚刚 Fork 的 `KVideo` 项目并点击 **Begin setup**。
 3. **配置构建参数**：
   - **Project name**: 默认为 `kvideo` (建议保持不变，后续链接基于此名称)
   - **Framework Preset**: 选择 `Next.js`
   - **Build command**: 输入 `npm run pages:build`
   - **Build output directory**: 输入 `.vercel/output/static`
   - 点击 **Save and Deploy**。
 4. **等待部署完成**：
   > 项目已内置 `wrangler.toml` 配置文件，其中包含 `nodejs_compat` 兼容性标志，无需手动配置。
 5. **如果部署失败**：
   > 如果看到 `Unknown internal error occurred` 错误，这通常是 Cloudflare 的临时服务端问题。请在 **Deployments** 列表中找到最新部署，点击 `...` 菜单选择 **Retry deployment** 重试即可。
   >
   > 如果首次部署仍有问题，可尝试在 **[项目设置页面](https://dash.cloudflare.com/?to=/:account/pages/view/kvideo/settings/production)** 底部的 **Compatibility flags** 中手动添加 `nodejs_compat`，然后重新部署。

 #### 选项 3：Vercel / Cloudflare 托管部署（合规模式）
 适用于只需要搜索、账户、设置、直连播放等基础能力，不需要外部媒体代理 / IPTV 中继的场景。
 1. **只从本地工作副本部署**：不要使用 GitHub 一键导入、Fork 后导入、Connect GitHub 读取仓库等流程。
 2. **Vercel**：使用本地 CLI 部署现有项目，参考官方文档：[Import an existing project](https://vercel.com/docs/getting-started-with-vercel/import)。
 3. **Cloudflare**：使用官方 **Direct Upload** 或 CLI 工作流，不要使用 Git integration，参考官方文档：[Getting started with Pages](https://developers.cloudflare.com/pages/get-started)。
 4. **Cloudflare Direct Upload 正确流程**：
   ```bash
   npm install
   npm run pages:build
   ```
   构建完成后，上传 **`.vercel/output/static`** 目录，而不是仓库根目录、`.next` 目录或源码文件。上传仓库根目录只会把源码当静态文件托管，根路径没有构建产物可供 Pages 入口加载，结果就是 404。
 5. **Cloudflare CLI 发布**：如果你使用 CLI，请发布同一个构建产物目录：
   ```bash
   npx wrangler pages deploy .vercel/output/static
   ```
 6. **Cloudflare 构建链路**：`npm run pages:build` 现在固定使用仓库内安装的 `next-on-pages` 和兼容版本的 `vercel`，避免构建时临时拉取不受控版本。`wrangler.toml` 继续提供 `nodejs_compat` 兼容标志。
 7. **功能限制**：托管平台会自动禁用外部媒体代理和 IPTV 流中继；请仅使用允许浏览器直连、允许当前来源访问且具备合法授权的内容源。
 8. **如果你需要完整能力**：直接改用 Docker 或传统 Node.js 自托管，不要在托管平台上强行恢复这些能力。

 ### Cloudflare Pages Direct Upload 部署后打开是 404
 这通常不是应用路由问题，而是上传了错误的目录。Cloudflare Pages 的 Direct Upload 需要上传已经构建完成的产物目录。

can4hou6joeng4	3bf72e4b66	fix(douban): 图片代理按镜像回退,修复境外部署海报大量 500 imgN.doubanio.com 互为镜像但解析到不同线路:img1 当前解析到国内 IP 180.97.198.41,在境外主机上不可达。此时 fetch 是直接抛异常而不是返回状态码,于是走进 catch 一律返回 500,首页会有相当比例的海报加载失败。改为在 imgN.doubanio.com 之间按 img9 -> img3 -> img2 顺序回退,同一路径换个镜像即可取到。同时保留最后一次的真实状态码,不再把上游的 403 或 404 也统一伪装成 500。	2026-07-31 18:32:34 +08:00
can4hou6joeng4	b63f94fed4	fix(sync): 丢弃缺少 videoId 的同步记录,避免整页崩溃服务端同步恢复回来的记录不保证结构完整(旧结构或半截写入)。缺少 videoId 的记录会让 HistoryItem.tsx:24 与 FavoritesItem.tsx:21 在渲染期拼播放地址时对 undefined 调用 toString(),抛出未捕获异常。由于 getVideoUrl() 是在渲染 href 时调用的,React 会直接卸载整棵树,首页白屏且刷新无效——该账号只能靠直接改库才能恢复。新增 lib/utils/sync-records.ts 做可渲染性判定(要求 videoId、source、 title 齐备),在云端拉取入口 useCloudSync 与 HistoryList / FavoritesList 各过滤一次:脏数据进不来,已经落库的也渲染不出来。	2026-07-31 18:28:35 +08:00
can4hou6joeng4	81c46d754e	fix(sync): 修复自托管下无法读取 Upstash 配置 app/api/user/{sync,config} 用 @upstash/redis/cloudflare 的 Redis.fromEnv() 创建客户端。该实现只读传入的 env 参数或 Cloudflare 全局绑定，从不回退到 process.env，因此在 Docker / Node 自托管下 url 与 token 恒为 undefined，两个接口必定返回 500，跨设备同步（收藏、历史、设置）完全不可用。认证走的是 auth.ts 里的 new Redis({ url, token })，所以登录正常，只有用户数据读写失败。把 auth.ts 中已有的双源回退抽成 lib/server/runtime-env.ts，Redis 客户端抽成 lib/server/redis.ts，两个路由改为惰性获取共享客户端。惰性创建同时修正了另一个隐患：Cloudflare 的 per-request 绑定在模块求值阶段不可达，而原先客户端是在模块作用域创建的。未配置 Upstash 时返回 503 并给出明确说明，而不是当成请求失败。 Fixes #226	2026-07-31 10:12:40 +08:00
