+# ReelShort 短剧服务（后端）
+
+短剧服务的服务端，Spring Boot + PostgreSQL，目前实现管理后台接口（`/admin/**`）。

+
+| 项 | 版本 |
+| --- | --- |
+| 运行时 | JDK 21（LTS），编译目标 Java 17 |
+| 框架 | Spring Boot 3.2.5、Spring Security 6、MyBatis-Plus 3.5.7 |
+| 数据库 | PostgreSQL 18 |
+| 构建 | Maven 3.10 多模块 |
+

+└── docs/                      架构设计文档
+```
+
+## 开发环境
+
+本机环境由 Homebrew 统一管理（版本以本机实际安装为准）：
+
+| 组件 | 版本 | 说明 |
+| --- | --- | --- |
+| Homebrew | 7.0.9 | 远端指向清华镜像，见文末常见问题 |
+| JDK | OpenJDK 21.0.12.1 | `brew install openjdk@21`，`JAVA_HOME` 已写入 `~/.zshrc` |
+| Maven | 3.10.0 | `brew install maven`，命令为 `/opt/homebrew/bin/mvn` |
+| PostgreSQL | 18.6 | `brew install postgresql@18`，`brew services start postgresql@18` 启动 |
+
+> `postgresql@18` 是 keg-only，命令行工具在 `/opt/homebrew/opt/postgresql@18/bin`，
+> 用之前把它加到 PATH：`export PATH="/opt/homebrew/opt/postgresql@18/bin:$PATH"`。
+
+```sh
+java -version   # openjdk 21.0.12.1
+mvn -v          # Maven 3.10.0 / Java 21.0.12.1
+```
+
+说明：
+
+- 工程编译目标为 Java 17（`maven.compiler.release=17`），在 JDK 21 上构建与运行。
+- 父 POM 显式声明了注解处理器（`<proc>full</proc>` + `annotationProcessorPaths`）：
+  JDK 23 起不再默认扫描 classpath 上的处理器，缺这段配置 Lombok 会失效。
+- 旧的 JDK 18 仍留在 `/Library/Java/JavaVirtualMachines/jdk-18.0.2.jdk`，删除需要 sudo，
+  不影响使用（`java_home` 与 `JAVA_HOME` 都已指向 21）。
+
+## 快速开始
+
+服务有两个入口，可以只启动其中一个：
+
+| 服务 | 模块 | 端口 | 面向 |
+| --- | --- | --- | --- |
+| 管理端 | `reelshort-admin-api` | 8080 | Vue 后台 |
+| 客户端 | `reelshort-app-api` | 8081 | Flutter 客户端 |
+
+### 1. 初始化数据库
+
+```sh
+export PATH="/opt/homebrew/opt/postgresql@18/bin:$PATH"
+cd /Users/jianghaifeng/Desktop/ReelShort/FruitServer
+psql -h 127.0.0.1 -U reelshort -d reelshort -f sql/schema.sql
+psql -h 127.0.0.1 -U reelshort -d reelshort -f sql/data.sql
+```
+
+数据库名 `reelshort`，角色 `reelshort`（密码 `reelshort`），两个脚本都可重复执行。
+首次搭建环境时先建角色与库：
+
+```sh
+psql -d postgres -c "CREATE ROLE reelshort LOGIN PASSWORD 'reelshort';"
+psql -d postgres -c "CREATE DATABASE reelshort OWNER reelshort ENCODING 'UTF8';"
+```
+
+连接信息在
+`reelshort-admin-api/src/main/resources/application.yml`，可用环境变量
+`DB_USER` / `DB_PASSWORD` / `JWT_ADMIN_SECRET` 覆盖。
+
+### 关于 PostgreSQL 的两点说明
+
+- 自增列用 `GENERATED BY DEFAULT AS IDENTITY`；`sql/data.sql` 里用了显式 ID，
+  脚本末尾会把序列 `setval` 到当前最大值，新增数据不会主键冲突。
+- PostgreSQL 没有 `ON UPDATE CURRENT_TIMESTAMP`，`updated_at` 由 `set_updated_at()`
+  触发器统一维护（见 `sql/schema.sql` 末尾），实体侧仍不参与更新该字段。
+- 轮播图的展示位置列名叫 `slot`（`position` 在 PostgreSQL 里是关键字），
+  实体用 `@TableField("slot")` 映射，对外接口字段仍是 `position`，前端无需改动。
+
+### 2. 构建
+
+```sh
+cd /Users/jianghaifeng/Desktop/ReelShort/FruitServer
+mvn -DskipTests package
+```
+
+### 3. 启动
+
+```sh
+cd /Users/jianghaifeng/Desktop/ReelShort/FruitServer
+java -jar reelshort-admin-api/target/reelshort-admin-api-1.0.0-SNAPSHOT.jar
+java -jar reelshort-app-api/target/reelshort-app-api-1.0.0-SNAPSHOT.jar
+```
+
+启动后：服务地址 `http://localhost:8080`，接口文档 `http://localhost:8080/doc.html`。
+
+## 默认账号
+
+密码均为 `admin123`。
+
+| 账号 | 角色 | 权限范围 |
+| --- | --- | --- |
+| admin | 超级管理员 | 全部 14 项权限 |
+| content.editor01 | 内容运营 | 短剧、剧集的增删改与封面上传 |
+| content.reviewer01 | 审核专员 | 查看内容、审核发布、数据报表 |
+| data.analyst01 | 数据分析师 | 查看短剧列表与数据报表 |
+
+## 接口一览
+
+### 认证 `/admin/auth`
+
+| 方法 | 路径 | 说明 |
+| --- | --- | --- |
+| POST | `/login` | 登录，返回 token 与权限码 |
+| GET | `/menus` | 当前用户菜单路由树（前端动态路由） |
+| GET | `/profile` | 当前登录人信息 |
+| POST | `/logout` | 登出（JWT 无状态，前端清除 token 即可） |
+| POST | `/password` | 修改自己的密码 |
+
+### 后台管理
+
+| 模块 | 接口 |
+| --- | --- |
+| 管理员 | `GET /admin/admin-users/page`、`POST /admin/admin-users`、`PUT\|DELETE /admin/admin-users/{id}`、`PUT /{id}/status`、`PUT /{id}/password` |
+| 角色 | `GET /admin/roles/page`、`GET /admin/roles/list`、`POST /admin/roles`、`PUT\|DELETE /admin/roles/{id}`、`GET\|PUT /admin/roles/{id}/permissions` |
+| 角色分类 | `GET\|POST /admin/role-categories`、`PUT\|DELETE /admin/role-categories/{id}` |
+| 权限点 | `GET /admin/permissions`（按分组返回，供权限配置页使用） |
+| 菜单 | `GET /admin/menus/tree`、`POST /admin/menus`、`PUT\|DELETE /admin/menus/{id}` |
+| 系统配置 | `GET\|PUT /admin/configs` |
+| 操作日志 | `GET /admin/operation-logs/page`（按操作人、模块、动作、结果、时间范围筛选）、`GET /admin/operation-logs/{id}` |
+| 字典 | `GET /admin/dicts/drama-category`、`GET /admin/dicts/content-status` |
+
+### 内容管理
+
+| 模块 | 接口 |
+| --- | --- |
+| 短剧 | `GET /admin/dramas/page`、`GET /admin/dramas/{id}`、`POST /admin/dramas`、`PUT\|DELETE /admin/dramas/{id}` |
+| 审核发布 | `POST /admin/dramas/{id}/submit`、`/approve`、`/reject`、`/publish`、`/offline` |
+| 审核记录 | `GET /admin/dramas/{id}/review-records` |
+| 剧集 | `GET /admin/episodes?dramaId=`、`POST /admin/episodes`、`PUT\|DELETE /admin/episodes/{id}`、`PUT /admin/episodes/sort` |
+| 轮播图 | `GET /admin/banners/page`、`POST /admin/banners`、`PUT\|DELETE /admin/banners/{id}`、`PUT /admin/banners/{id}/status`、`PUT /admin/banners/sort` |
+| 短剧类型 | `GET\|POST /admin/drama-categories`、`PUT\|DELETE /admin/drama-categories/{id}`（权限沿用 `drama:*`） |
+
+### 媒资 `/admin/media`
+
+| 方法 | 路径 | 说明 |
+| --- | --- | --- |
+| POST | `/upload/init` | 建立分片会话，返回 `uploadId`、`chunkSize`、`totalChunks` |
+| POST | `/upload/chunk` | 上传单个分片（multipart：`uploadId`、`index`、`file`） |
+| POST | `/upload/complete` | 合并分片，返回媒资（含可访问的 `url`） |
+| GET | `/{id}` | 查询媒资 |
+
+## 媒资存储（本地）
+
+当前没有对象存储，文件直接落在本机磁盘：
+
+| 项 | 默认值 | 说明 |
+| --- | --- | --- |
+| 存储目录 | `./data/uploads` | 配置项 `reelshort.media.root-dir`，按 `业务类型/年月/uuid.ext` 分目录 |
+| 访问前缀 | `/files/**` | 配置项 `reelshort.media.public-prefix`，映射为静态资源 |
+| 分片大小 | 5MB | `reelshort.media.chunk-size`，单文件上限 2GB |
+| 请求上限 | 20MB | `spring.servlet.multipart`，只需容纳一个分片 |
+
+要点：
+
+- `/files/**` 在 `SecurityConfig` 里是公开路径，因为 `<img>` / `<video>` 无法携带请求头。
+- 上传权限：封面用 `cover:upload`，视频用 `episode:upload`。
+- `data/` 是运行时产物，不需要提交到版本库。
+- 换成 OSS/S3 时只需替换 `MediaStorageService`（分片落盘、合并、生成访问地址三处），
+  `MediaService` 与前端接口都不用动。
+
+## 统一约定
+
+- 响应体 `{ code, message, data }`，成功 `code=0`。
+- 分页请求 `pageIndex`（从 1 开始）、`pageSize`，响应 `{ total, list }`。
+- 鉴权头 `Authorization: Bearer <token>`；未登录 `code=401`，无权限 `code=403`。
+- 错误码见架构文档附录 A；业务错误如 `100000` 账号密码错误、`200003` 状态不允许该操作。
+
+## 权限模型
+
+## 客户端接口 `/app/**`
+
+面向 Flutter 客户端，只暴露已上线内容，不含审核状态、操作日志等管理端字段。
+
+| 方法 | 路径 | 说明 |
+| --- | --- | --- |
+| GET | `/app/home/feed` | 首页聚合：轮播（HOME_TOP）+ 分区（热门 / 新剧 / 各分类） |
+| GET | `/app/discover/feed` | 发现页聚合：轮播（DISCOVER）+ 分类分区 |
+| GET | `/app/categories` | 分类列表 |
+| GET | `/app/dramas/{id}` | 详情，含剧集列表，一次请求即可渲染详情页 |
+| GET | `/app/episodes/{id}/play` | 播放票据 |
+
+约定：
+
+- 只返回 `status = published` 的短剧与剧集，未上线按不存在处理。
+- 图片与视频返回相对路径（`/files/...`），客户端拼上服务地址即可。
+- 播放票据三种结果：`FREE`（返回 `playUrl`）、`COIN_REQUIRED`（返回 `unlockCoin`）、
+  `NO_MEDIA`（已上线但还没传视频）。
+- `/app/**` 目前在安全配置里放行（浏览无需登录）；手机号/邮箱登录与权益体系接入后再收紧。
+
+性能（本机实测，预热后 30 次采样，目标 50ms）：
+
+| 接口 | 平均 | P95 | 最大 | 响应体 |
+| --- | --- | --- | --- | --- |
+| `/app/home/feed` | 13.6ms | 20.3ms | 23.4ms | 3.9KB |
+| `/app/discover/feed` | 7.3ms | 8.1ms | 8.8ms | 1.7KB |
+| `/app/categories` | 2.0ms | 2.1ms | 3.4ms | 0.2KB |
+| `/app/dramas/{id}` | 2.8ms | 3.1ms | 3.5ms | 0.7KB |
+| `/app/episodes/{id}/play` | 2.2ms | 2.6ms | 3.3ms | 0.2KB |
+
+`SlowRequestLogger` 会对超过 50ms 的 `/app/**` 请求打 WARN 日志，
+内容量增长或索引失效时能第一时间发现；首页聚合是查询最多的一档（分类 + 热门 + 新剧 + 各分类列表），
+如果将来分类变多，优先给它加缓存。
+
+## 权限模型
+
+- 权限码随 JWT 下发（如 `drama:create`、`banner:list`），控制器用
+  `@PreAuthorize("@ss.hasPermission('drama:create')")` 校验。
+- 菜单树由权限码派生：角色拥有哪些权限，就可见哪些菜单。
+- 内容状态机：`draft → reviewing → approved → published → offline`。
+  草稿不能直接发布，已上线的短剧需先下线才能删除；每次流转写入审核记录与操作日志。
+- 鉴权实时读库（`PermissionChecker` 通过 `PermissionProvider` 查当前用户的权限），
+  后台改了角色权限或菜单，**前端刷新一下即可生效，不用重新登录**。
+  前端在每次进入应用时会重新拉取 `GET /admin/auth/menus` 与 `GET /admin/auth/profile`。
+
+## 操作日志
+
+后台写操作由切面自动记录，**不需要在每个接口里手写**，在控制器方法上加注解即可：
+
+```java
+@OperationLog(module = "内容管理", action = "新增短剧类型")
+public Result<Long> create(@Valid @RequestBody DramaCategorySaveReqVO req) { ... }
+```
+
+每次调用记录：操作人、操作时间、模块、动作、请求方式与地址、请求参数、请求体、
+响应体、成功/失败、错误信息、耗时、IP。
+
+约定：
+
+- 只记写操作（POST/PUT/DELETE），GET 查询不入库，避免刷屏。
+- 请求体与响应体超过 4000 字符会截断；密码、密钥、token 等字段自动替换成 `***`。
+- 业务异常记 `FAIL` 并带错误信息；`@PreAuthorize` 拦下的越权访问由
+  `AccessDeniedRecorder` 单独记一条（模块=安全，动作=越权访问被拒绝）。
+- 日志写入失败不影响业务（切面内兜底 try/catch）。
+- 查看入口：后台管理 → 操作日志，权限码 `log:list`，默认只给超级管理员。
+
+## 前端对接
+
+管理后台 `../ReelShortWeb` 已完成全部对接，本地演示数据已删除：
+
+| 页面 | 使用接口 |
+| --- | --- |
+| 登录 / 左侧菜单 | `POST /admin/auth/login`、`GET /admin/auth/menus` |
+| 工作台 | `GET /admin/dramas/page`（统计与最近更新） |
+| 短剧管理 | `/admin/dramas/**`、`/admin/dicts/drama-category`、审核发布动作 |
+| 剧集管理 | `/admin/episodes/**`、`PUT /admin/episodes/sort` |
+| 角色权限配置 | `/admin/roles/**`、`GET /admin/permissions`、`GET /admin/role-categories` |
+| 管理员用户列表 | `/admin/admin-users/**` |
+| 菜单管理 | `GET /admin/menus/tree` + 增删改 |
+| 角色分类 | `/admin/role-categories/**` |
+| 系统设置 | `GET\|PUT /admin/configs` |
+
+前端侧改动：
+
+1. `.env.base` 关闭 mock（`VITE_USE_MOCK=false`）；
+2. `vite.config.mts` 增加 `/admin` 代理到 `http://127.0.0.1:8080`；
+3. `src/api/admin/*.ts` 封装全部管理端接口；
+4. 请求头自动携带 `Authorization: Bearer <token>`；
+5. `src/stores/rbac.js` 的 `can(code)` 改用登录返回的权限码，
+   原 `src/data/`、`src/permissions/` 下的演示数据已删除；
+6. 表格状态列改用接口返回的 `status` / `statusText`，
+   大数值用 `src/utils/format.js` 的 `formatCount` 格式化。
+
+## 尚未实现
+
+视频转码（HLS 多码率）、C 端接口（`/app/**`）、金币与会员、单集解锁、支付与对账、
+数据看板统计、Redis 缓存与限流。详见架构设计文档第 11 章。
+
+## 常见问题
+
+**编译报「找不到符号 getXxx / 无法推断类型参数」**
+Lombok 注解处理器没跑起来。确认是在 JDK 21 下构建（`mvn -v` 应显示 Java 21），
+父 POM 已声明 `annotationProcessorPaths`，若仍报错先 `mvn clean`。
+
+**8080 端口被占用**
+
+```sh
+lsof -tiTCP:8080 -sTCP:LISTEN | xargs kill
+```
+
+**brew 连不上 GitHub**
+本机访问 `github.com` 不通，brew 仓库已改用清华镜像：
+
+```sh
+git -C /opt/homebrew remote set-url origin https://mirrors.tuna.tsinghua.edu.cn/git/homebrew/brew.git
+```
+
+Bottle 走 USTC 镜像（环境变量 `HOMEBREW_BOTTLE_DOMAIN`）。
+要换回官方源，把 `origin` 改回 `https://github.com/Homebrew/brew` 即可。
+
+**临时切换 JDK**
+
+```sh
+export JAVA_HOME=$(/usr/libexec/java_home -v 21)
+```
+
+Homebrew 的 Maven 在 `JAVA_HOME` 未设置时会回退到它自带的 JDK（当前为 27），
+父 POM 的注解处理器配置保证这种情况下也能编译通过。

+# ReelShort 短剧服务 · 后端架构设计
+
+> 技术栈：JDK 21（LTS，编译目标 Java 17）+ Spring Boot 3.2 + PostgreSQL 18 + Redis
+>
+> 实现说明：项目已从 MySQL 切换到 PostgreSQL。本文档第 5 章的 DDL 仍按 MySQL 语法书写，
+> 实际建表语句见 `sql/schema.sql`（PostgreSQL 版），两者的字段与索引一一对应；
+> 主要差异是自增列用 IDENTITY、`updated_at` 用触发器维护、索引独立创建。
+> 面向两端：管理后台（ReelShortWeb / Vue3）、客户端（ReelShort / Flutter）
+> 版本：v1（2026-10-14）
+
+---
+
+## 1. 背景与目标
+
+### 1.1 现状
+
+| 端 | 目录 | 技术 | 状态 |
+| --- | --- | --- | --- |
+| 管理后台 | `ReelShort/ReelShortWeb` | Vue3 + Vite + element-plus-admin | 页面完成，数据为前端 mock |
+| 客户端 | `ReelShort/ReelShort` | Flutter | 页面完成，数据为本地演示数据 |
+| 服务端 | `FruitServer` | Spring Boot 3 + MyBatis-Plus + PostgreSQL | 已实现 |
+
+两端的领域模型已经落在代码里，后端要按它们已有的字段和交互来设计，而不是重新发明一套：
+
+- 后台：短剧（`title / genre / status / episodes / views / updatedAt / description / cover`）、剧集（`dramaId / number / title / duration / status / views`）、角色、角色分类、权限点、菜单、管理员、系统设置。
+- 客户端：短剧目录、剧集列表（`isFree` 决定能否播放）、收藏、点赞、评论、观看历史、金币、会员。
+- 后台现在靠 mock 提供登录（`POST /mock/user/login`）与菜单路由树（`GET /mock/role/list`）；统一响应壳是 `{ code: 0, message, data }`，鉴权头是 `Authorization`，`code === 401` 触发登出。后端必须能一比一替换掉这两个 mock。
+
+### 1.2 设计目标
+
+1. 一套服务同时支撑 B 端（管理后台）与 C 端（客户端），共用内容域数据。
+2. 先做模块化单体，边界清晰，规模上来后可按模块拆分，不做超前微服务化。
+3. 内容生产链路（上传 → 转码 → 审核 → 发布）与播放链路（鉴权 → 签名地址 → 防盗链）是两条主线，一次设计到位。
+4. 变现能力（金币 / 会员 / 单集解锁 / 充值订单）从第一天就纳入领域模型，避免后期改表。
+
+---
+
+## 2. 总体架构

+
+分层原则：
+
+- 接入层：`admin-api` 与 `app-api` 是两个独立入口，各自独立的鉴权过滤器、限流策略、参数校验，互不污染。
+- 领域层：按业务域切模块（system / content / media / member / interaction / trade / stat），模块之间只通过 Service 接口调用，禁止跨模块直连 Mapper。
+- 基础设施层：`framework` 收敛所有技术细节（安全、缓存、MyBatis、日志、OSS SDK），业务模块不直接依赖第三方 SDK。

+
+## 3. 技术选型
+
+| 领域 | 选型 | 说明 |
+| --- | --- | --- |
+| 语言/运行时 | JDK 21（LTS） | 编译目标 Java 17；Spring Boot 3 要求 17+ |
+| 框架 | Spring Boot 3.2.x + Spring MVC | 前后端分离，纯 REST |
+| 持久层 | MyBatis-Plus 3.5.x | 后台 CRUD 密集，代码生成 + 分页插件省事 |
+| 数据库 | PostgreSQL 18（UTF8） | 逻辑删除 + 乐观锁字段统一规范；DDL 见 sql/schema.sql |
+| 缓存 | Redis 7 | 登录态、验证码、热点目录、播放签名、分布式锁 |
+| 鉴权 | Spring Security + JWT（jjwt） | B 端与 C 端共用签发逻辑，各自独立过滤器 |
+| 对象存储 | 阿里云 OSS / S3 兼容（本地用 MinIO） | 视频与封面，分片直传 |
+| 转码 | FFmpeg + 异步队列 | 产出 HLS（多码率）+ MP4 兜底 + 首帧封面 |
+| 消息队列 | RabbitMQ（起步） | 转码任务、订单超时、统计埋点；量级大再换 Kafka |
+| 接口文档 | springdoc-openapi | 自动生成 OpenAPI 3 |
+| 定时任务 | Spring Scheduling / XXL-Job | 定时发布、日报聚合、支付对账 |
+| 构建 | Maven 多模块 | 见第 4 节 |
+

+## 4. 工程结构（Maven 多模块）
+
+```
+java/
+├── pom.xml                       # 聚合父 POM，统一依赖版本
+├── reelshort-common/             # 统一响应/异常/常量/枚举/工具
+├── reelshort-framework/          # 安全、MyBatis、Redis、日志、限流、OSS、MQ 客户端
+├── reelshort-module-system/      # 管理员、角色、权限、菜单、配置、操作日志
+├── reelshort-module-content/     # 短剧、剧集、分类标签、审核发布
+├── reelshort-module-media/       # 媒资上传、转码、播放地址签名
+├── reelshort-module-member/      # C 端用户、登录、设备、资料

+├── reelshort-app-api/            # C 端接口，/app/**
+└── reelshort-job/                # 定时任务与异步消费者
+```
+
+起步阶段若不想铺这么开，可先合并为 `reelshort-common` + `reelshort-server`（含 system/content/media）+ `reelshort-app-api`，但包结构仍按域划分（`com.reelshort.content.*`），后续拆模块零成本。
+
+模块内部结构保持一致：
+
+```
+com.reelshort.content
+├── controller/        # 仅 admin-api / app-api 暴露
+├── service/           # 接口 + impl
+├── dal/
+│   ├── entity/        # 数据库实体
+│   ├── mapper/        # MyBatis-Plus Mapper
+│   └── redis/         # 该域的缓存操作
+├── convert/           # entity <-> VO/DTO 转换（MapStruct）
+└── api/               # 暴露给其它模块的 Service 接口
+```
+
+命名约定：
+
+- 包名 `com.reelshort.<module>.<layer>`
+- 实体 `Drama`、`DramaEpisode`、`AppUser`
+- 请求对象 `XxxCreateReqVO` / `XxxUpdateReqVO` / `XxxPageReqVO`，响应对象 `XxxRespVO`
+- 表名 `<域前缀>_<业务>`，如 `drama`、`drama_episode`、`sys_role`、`app_user`、`stat_drama_daily`
+
+---
+
+## 5. 领域模型与数据库设计
+
+### 5.1 设计约定
+
+- 主键统一 `bigint unsigned`；对外可选用雪花 ID，不暴露自增趋势。
+- 所有表带 `created_at / updated_at`，业务表带 `deleted tinyint default 0`（逻辑删除）。
+- 金额一律用 `int` 分或 `bigint` 微单位，禁用 float；金币用 `bigint`。
+- 状态字段存英文码，中文只用于前端展示，不把界面文案写进数据库。后台现有文案映射：
+
+| 前端展示 | 存储码 |
+| --- | --- |
+| 草稿 | `draft` |
+| 审核中 / 待审核 | `reviewing` |
+| 待发布 | `approved` |
+| 已上线 | `published` |
+| 已下线 | `offline` |

+## 6. 接口设计
+
+### 6.1 统一约定
+
+- 基础路径：B 端 `/admin/**`，C 端 `/app/**`。
+- 响应壳（与后台 axios 拦截器一致）：`{ "code": 0, "message": "ok", "data": ... }`；失败 `code != 0`；未登录 `code = 401`。
+- 分页：请求 `pageIndex`（从 1 开始）、`pageSize`；响应 `{ "total": n, "list": [...] }`。
+- 鉴权：请求头 `Authorization: Bearer <token>`；B 端与 C 端 token 独立签发、独立校验。
+- 时间：`yyyy-MM-dd HH:mm:ss` 或毫秒时间戳，全项目统一一种。
+
+### 6.2 B 端接口
+
+必须与现有 mock 结构兼容的两个接口：
+
+| 方法 | 路径 | 说明 | 兼容要求 |
+| --- | --- | --- | --- |
+| POST | `/admin/auth/login` | 管理员登录 | 返回 `data` 至少含 `username / role / roleId / token`，字段名与 `mock/user/index.mock.ts` 一致；`permissions` 换为真实权限码数组 |
+| GET | `/admin/auth/menus` | 当前用户菜单路由树 | 结构与 `mock/role/index.mock.ts` 的 `adminList` 完全一致（`path / component / name / meta.title / meta.icon`），`component` 仍是前端组件字符串 |
+
+其余 B 端接口：
+
+| 模块 | 接口 |
+| --- | --- |
+| 认证 | `POST /admin/auth/login`、`POST /admin/auth/logout`、`GET /admin/auth/profile`、`POST /admin/auth/password` |
+| 管理员 | `GET /admin/admin-users/page`、`POST /admin/admin-users`、`PUT /admin/admin-users/{id}`、`DELETE /admin/admin-users/{id}`、`PUT /admin/admin-users/{id}/status`、`PUT /admin/admin-users/{id}/password` |
+| 角色 | `GET /admin/roles/page`、`POST /admin/roles`、`PUT /admin/roles/{id}`、`DELETE /admin/roles/{id}`、`GET /admin/roles/{id}/permissions`、`PUT /admin/roles/{id}/permissions` |

+| 菜单 | `GET /admin/menus/tree`、`POST /admin/menus`、`PUT /admin/menus/{id}`、`DELETE /admin/menus/{id}` |
+| 短剧 | `GET /admin/dramas/page`、`GET /admin/dramas/{id}`、`POST /admin/dramas`、`PUT /admin/dramas/{id}`、`DELETE /admin/dramas/{id}`、`PUT /admin/dramas/{id}/status` |
+| 剧集 | `GET /admin/dramas/{dramaId}/episodes`、`POST /admin/episodes`、`PUT /admin/episodes/{id}`、`DELETE /admin/episodes/{id}`、`PUT /admin/episodes/sort` |
+| 审核 | `POST /admin/dramas/{id}/submit`、`/approve`、`/reject`、`/publish`、`/offline` |
+| 媒资 | `POST /admin/media/upload-token`（分片直传凭证）、`POST /admin/media/upload`（小文件）、`GET /admin/media/{id}`（转码进度） |
+| 字典 | `GET /admin/dicts/{type}`（题材、状态等） |
+| 设置 | `GET /admin/configs`、`PUT /admin/configs` |
+| 统计 | `GET /admin/stat/overview`、`GET /admin/stat/dramas`、`GET /admin/stat/trend` |
+
+短剧列表响应示例（字段名对齐前端 `src/data/dramas.js`，前端只需换数据源）：
+
+```json
+{
+  "id": 1,
+  "title": "替嫁新娘：总裁的掌心宠",

+  "description": "一场意外替嫁，让她成为冷面总裁的契约新娘。",
+  "updatedAt": "2025-06-12 10:00:00"
+}
+```
+
+### 6.3 C 端接口
+
+| 模块 | 接口 | 说明 |
+| --- | --- | --- |
+| 认证 | `POST /app/auth/sms-code` | 发送验证码（Redis 限流防刷） |
+| | `POST /app/auth/login` | 手机号+验证码 / 邮箱+密码，返回 `accessToken`、`refreshToken`、用户资料 |

+
+播放接口响应示例：
+
+```json
+{
+  "episodeId": 101,
+  "dramaId": 1,
+  "epNo": 4,
+  "duration": 138,
+  "accessible": true,
+  "accessType": "FREE",
+  "playUrl": "https://cdn.example.com/hls/1/101/index.m3u8?auth_key=...&expires=1730000000",
+  "posterUrl": "https://cdn.example.com/hls/1/101/poster.jpg",
+  "resumePosition": 42
+}
+```
+
+`accessible = false` 时返回 `accessType = COIN_REQUIRED | VIP_REQUIRED` 与 `unlockCoin`，客户端据此弹出解锁或开通会员面板。
+
+---
+
+## 7. 关键流程
+
+### 7.1 内容生产（后台）
+
+```
+创建短剧草稿 → 上传封面 → 批量上传剧集视频（分片直传 OSS）
+  → 发布转码任务（MQ 异步） → FFmpeg 产出 HLS/封面 → 回调更新 media_asset
+  → 填写剧集信息（集号、时长、免费标记、解锁金币）
+  → 提交审核（draft → reviewing） → 审核通过（reviewing → approved）
+  → 定时或手动发布（approved → published，publish_at 到点由 job 自动上线）
+  → 客户端目录可见
+```
+
+- 转码异步化，后台轮询 `GET /admin/media/{id}` 拿进度即可，不用长连接。
+- 审核、发布、下线三个动作全部写 `drama_review_record` 与 `sys_operation_log`，可追溯。
+
+### 7.2 播放链路（客户端）
+
+```
+客户端请求 POST /app/episodes/{id}/play
+  → 校验登录态与用户状态
+  → 判定可见性：剧 / 集是否 published
+  → 判定播放权：is_free 命中，或 episode_unlock 命中，或 VIP 有效
+  → 有权：生成带签名的 CDN 地址（有效期 10~30 分钟）→ 返回 playUrl + 续播位置
+  → 无权：返回 COIN_REQUIRED / VIP_REQUIRED，客户端弹窗引导
+```
+
+防盗链三条措施：签名地址短时效、CDN Referer/UA 白名单、HLS 分片加密（AES-128，密钥接口同样鉴权）。
+
+### 7.3 解锁扣费（幂等）
+
+```
+POST /app/episodes/{id}/unlock
+  → 幂等键 user_id + episode_id：先查 episode_unlock，命中直接返回成功
+  → Redis 分布式锁 lock:unlock:{userId}:{episodeId}，挡住连点重复扣费
+  → 一个事务内：扣 user_coin_account（乐观锁 version 校验）
+                → 写 coin_transaction → 写 episode_unlock
+  → 返回最新余额
+```
+
+余额不足返回明确业务码，客户端直接跳充值页。
+
+### 7.4 支付回调
+
+```
+POST /app/pay/callback/{channel}
+  → 验签 → 幂等（channel + channel_trade_no 唯一索引）
+  → 一个事务内：订单置为 PAID → 金币入账（写流水）或开通/续期 VIP
+                → 更新 app_user.vip_expire_at
+  → 返回渠道要求的成功应答
+```
+
+配套对账任务：定时拉取渠道账单与本地订单比对，处理「渠道成功、本地漏回调」。
+
+---
+
+## 8. 非功能设计
+
+### 8.1 鉴权与权限
+
+- B 端：JWT 载荷含 `userId / username / roleId`，过滤器解析后写入 `SecurityContext`；权限校验用注解 `@PreAuthorize("@ss.hasPermission('drama:create')")`，权限码风格与前端 `src/permissions/permissions.js` 对齐。
+- C 端：`accessToken` 短时效（2h）+ `refreshToken` 长时效（30d），存 Redis 支持主动踢下线；键设计 `user:token:{userId}:{deviceId}`。
+- 后台高危操作（删除、发布、改权限）二次校验密码并写 `sys_operation_log`；`two_factor` 字段已在表结构预留。
+
+### 8.2 缓存策略
+
+| 数据 | Key | 策略 |
+| --- | --- | --- |
+| 首页/发现页分区 | `cache:home:feed` | 5 分钟过期，发布/上线/下线时主动失效 |
+| 短剧详情 | `cache:drama:{id}` | 10 分钟 + 主动失效 |
+| 分类字典 | `cache:dict:category` | 1 小时 |
+| 后台权限码 | `cache:perm:role:{roleId}` | 30 分钟，改角色权限时失效 |
+| 验证码 | `sms:code:{mobile}` | 5 分钟，发送限流 1 次/分、5 次/天 |
+| 播放签名 | —— | 不缓存，实时生成 |
+
+热点 Key 加随机后缀防雪崩；空结果缓存短空值防穿透。
+
+### 8.3 限流与防刷
+
+- 接口级限流（Redis 令牌桶）：登录、验证码、评论、解锁扣费。
+- 播放量与观看时长上报去重（`user_id + episode_id + 时间窗`），防止刷量污染统计。
+- 评论接入敏感词过滤，可扩展到第三方内容安全审核。
+- 客户端接口做版本兼容（`X-App-Version`），避免旧版本升级后崩溃。
+
+### 8.4 数据量与扩展
+
+- 增长最快的表：`user_watch_history`、`drama_comment`、`coin_transaction`、`stat_*_daily`。
+- 单表超 2000 万行或写入明显变慢时，按 `user_id` 取模分表（ShardingSphere），对业务代码透明。
+- `stat_*_daily` 属聚合表，量级可控，用分区表即可。
+- 图片与视频全部走 CDN，应用服务器不落盘媒体文件。
+
+### 8.5 可观测与运维
+
+- 日志：JSON 结构化，traceId 贯穿全链路；后台敏感操作另写 `sys_operation_log`。
+- 监控：接口 P99、错误率、转码队列积压、支付回调失败率、Redis 命中率。
+- 健康检查 `/actuator/health` 暴露给负载均衡。
+- 环境：dev / test / prod 三套配置，密钥通过环境变量注入，不写进仓库。
+
+---
+
+## 9. 部署与演进
+
+起步形态（单体）：
+
+```
+Nginx
+ ├── reelshort-admin-api  (/admin)
+ ├── reelshort-app-api    (/app)
+ └── reelshort-job        (定时任务、异步消费)
+PostgreSQL(主从) / Redis / OSS(或 MinIO) / 转码 Worker(独立容器，可多实例水平扩容)
+```
+
+Docker Compose 足够跑通全链路，上线后按量升级到 K8s。
+
+演进路径：单体多模块 → 转码与统计独立进程 → 读写分离 → 内容域/交易域拆为独立服务 → 网关统一入口。拆分只在某模块成为独立瓶颈或有独立迭代节奏时进行，不为拆而拆。
+
+---
+
+## 10. 与现有前端的对接改造点
+
+### 10.1 管理后台（ReelShortWeb）
+
+1. `.env.*`：`VITE_USE_MOCK=false`，`VITE_API_BASE_PATH` 指向后端地址。
+2. 登录：`src/api/login/index.ts` 的 `/mock/user/login` → `/admin/auth/login`，返回体保持 `{ username, role, roleId, token, permissions }`，前端改动最小。
+3. 菜单：`/mock/role/list` → `/admin/auth/menus`，返回同样的路由树结构，`src/router/index.ts` 无需改动。
+4. 业务数据源替换：
+   - `src/data/dramas.js` → `GET /admin/dramas/page`
+   - `src/data/episodes.js` → `GET /admin/dramas/{dramaId}/episodes`
+   - `src/data/roles.js` → `GET /admin/roles/page`
+   - `src/views/userManagement/data/adminUsers.js` → `GET /admin/admin-users/page`
+   - `src/data/customMenus.js`（localStorage）→ `GET/POST /admin/menus`
+   - `src/stores/rbac.js` 的本地权限表 → 登录返回的 `permissions` + `GET /admin/permissions`
+5. 展示文案（已上线/审核中/草稿）改由 `status` 码映射，`src/utils/status.js` 可逐步改用后端返回的 `statusText`。
+
+### 10.2 客户端（ReelShort / Flutter）
+
+1. `DemoCatalogRepository` → HTTP 实现，对接 `/app/home/feed`、`/app/dramas/{id}`、`/app/dramas/{id}/episodes`。
+2. `SharedPreferencesEngagementRepository`（收藏/点赞/评论本地存储）→ HTTP 实现，`EngagementSnapshot` 变为服务端快照。
+3. 观看历史本地存储 → `/app/history`；登录后做一次本地数据合并上传。
+4. `Episode.isFree` 与 `PlaybackSession.canPlay` → 由 `/play` 返回的 `accessible / accessType` 驱动。
+5. 「我的」页金币与会员（当前是 `$ 0` 假数据）→ `/app/wallet`。
+6. 新增登录页，token 用 `flutter_secure_storage` 保存，`refreshToken` 自动续期。
+
+---
+
+## 11. 迭代建议
+
+**M1 · 打通后台**
+系统域（登录、RBAC、菜单、管理员）+ 内容域（短剧/剧集 CRUD）+ 媒资上传（先整文件上传，转码后置）+ 统一响应与鉴权框架。目标：后台 mock 全部替换为真实接口。
+
+**M2 · 打通客户端**
+C 端登录、目录/详情/剧集、观看历史、收藏点赞评论、播放鉴权与签名地址。目标：客户端真实播放，前端演示仓库全部退役。
+
+**M3 · 变现与质量**
+转码流水线（HLS 多码率）、金币与会员、单集解锁、支付与对账、后台数据看板、限流防刷、监控告警。
+
+**M4 · 规模化**
+读写分离、热点缓存优化、大表分表、内容安全、多语言内容（`drama.language` 已预留）。
