+# 配置指南
+
+BingPaper 支持通过配置文件（YAML）和环境变量进行配置。
+
+## 配置文件
+
+程序启动时默认会查找当前目录下的 `config.yaml` 或 `data/config.yaml`。如果不存在，会自动在 `data/config.yaml` 创建一份带有默认值的配置文件。
+
+你可以通过命令行参数 `-config` 或 `-c` 指定配置文件路径：
+
+```bash
+./BingPaper -c my_config.yaml
+```
+
+### 完整配置说明
+
+以下是 `config.example.yaml` 的详细说明：
+
+#### server (服务配置)
+- `port`: 服务监听端口，默认 `8080`。
+- `base_url`: 服务的基础 URL，用于生成某些绝对路径，默认为空。
+
+#### log (日志配置)
+- `level`: 业务日志级别，可选 `debug`, `info`, `warn`, `error`，默认 `info`。
+- `filename`: 业务日志输出文件路径，默认 `data/logs/app.log`。
+- `db_filename`: 数据库日志输出文件路径，默认 `data/logs/db.log`。
+- `max_size`: 日志文件切割大小 (MB)，默认 `100`。
+- `max_backups`: 保留旧日志文件个数，默认 `3`。
+- `max_age`: 保留旧日志文件天数，默认 `7`。
+- `compress`: 是否压缩旧日志文件，默认 `true`。
+- `log_console`: 是否同时输出到控制台，默认 `true`。
+- `show_db_log`: 是否在控制台输出数据库日志（SQL），默认 `false`。
+- `db_log_level`: 数据库日志级别，可选 `debug`, `info`, `warn`, `error`, `silent`。`debug`/`info` 会记录所有 SQL。默认 `info`。
+
+#### api (API 模式)
+- `mode`: API 行为模式。
+    - `local`: (默认) 接口直接返回图片的二进制流，适合图片存储对外部不可见的情况。
+    - `redirect`: 接口返回 302 重定向到图片的 `PublicURL`，适合配合 S3 或 WebDAV 的公共访问。
+- `enable_mkt_fallback`: 当请求的地区不存在或无数据时，是否允许兜底回退到默认地区或任意可用地区，默认 `true`。
+
+#### cron (定时任务)
+- `enabled`: 是否启用定时抓取，默认 `true`。
+- `daily_spec`: Cron 表达式，定义每日抓取时间。默认 `"0 10 * * *"` (每日上午 10:00)。
+
+#### fetcher (抓取配置)
+- `regions`: 需要抓取的地区编码列表（如 `zh-CN`, `en-US` 等）。如果不设置，默认为包括主要国家在内的 17 个地区。
+
+#### retention (数据保留)
+- `days`: 图片及元数据保留天数。超过此天数的数据可能会被清理任务处理。设置为 `0` 表示永久保留，不进行自动清理。默认 `0`。
+
+#### db (数据库配置)
+- `type`: 数据库类型，可选 `sqlite`, `mysql`, `postgres`。默认 `sqlite`。
+- `dsn`: 数据库连接字符串。
+    - SQLite: `data/bing_paper.db` (默认)
+    - MySQL 示例: `user:pass@tcp(127.0.0.1:3306)/dbname?charset=utf8mb4&parseTime=True&loc=Local`
+    - Postgres 示例: `host=localhost user=user password=pass dbname=db port=5432 sslmode=disable TimeZone=Asia/Shanghai`
+
+**注意：** BingPaper 支持数据库配置的热更新。如果你在程序运行时修改了 `db.type` 或 `db.dsn`，程序会自动尝试将当前数据库中的所有数据（图片记录、变体信息、Token）迁移到新的数据库中。
+- 在迁移开始前，程序会**清空**目标数据库中的相关表以防止数据冲突。
+- 迁移过程在事务中执行，确保数据一致性。
+- 迁移完成后，程序将无缝切换到新的数据库连接。
+
+#### storage (存储配置)
+- `type`: 存储类型，可选 `local`, `s3`, `webdav`。默认 `local`。
+- **local (本地存储)**:
+    - `root`: 图片存储根目录，默认 `data/picture`。
+- **s3 (对象存储)**:
+    - `endpoint`: S3 端点（如 `s3.amazonaws.com` 或 MinIO 地址）。
+    - `region`: 区域（如 `us-east-1`）。
+    - `bucket`: 桶名称。
+    - `access_key`: 访问密钥 ID。
+    - `secret_key`: 私有访问密钥。
+    - `public_url_prefix`: 公网访问前缀，若为空则由 SDK 自动尝试生成。
+    - `force_path_style`: 是否强制使用路径样式（MinIO 等通常需要设为 `true`）。
+- **webdav (WebDAV 存储)**:
+    - `url`: WebDAV 服务器地址。
+    - `username`: 用户名。
+    - `password`: 密码。
+    - `public_url_prefix`: 公网访问前缀。
+
+#### admin (管理配置)
+- `password_bcrypt`: 管理员密码的 Bcrypt 哈希值。默认密码为 `admin123`，对应哈希 `$2a$10$fYHPeWHmwObephJvtlyH1O8DIgaLk5TINbi9BOezo2M8cSjmJchka`。
+    - **强烈建议修改此项。**
+
+#### token (认证配置)
+- `default_ttl`: 管理后台登录 Token 的默认有效期，默认 `168h` (7天)。
+
+#### feature (功能开关)
+- `write_daily_files`: 是否在每日目录下写入原始文件（不仅是数据库记录），默认 `true`。
+
+#### web (静态资源)
+- `path`: 自定义管理后台前端文件的存放路径，默认 `web`。若指定路径不存在，将尝试使用内置的嵌入页面。
+
+---
+
+## 环境变量配置
+
+所有的配置项都可以通过环境变量进行覆盖。环境变量前缀为 `BINGPAPER_`，层级之间使用下划线 `_` 分隔。
+
+**常用示例：**
+
+- `BINGPAPER_SERVER_PORT=9090`
+- `BINGPAPER_DB_TYPE=mysql`
+- `BINGPAPER_DB_DSN="user:pass@tcp(127.0.0.1:3306)/bingpaper"`
+- `BINGPAPER_STORAGE_TYPE=s3`
+- `BINGPAPER_STORAGE_S3_BUCKET=my-images`
+- `BINGPAPER_ADMIN_PASSWORD_BCRYPT="$2a$10$..."`
+- `HOST_PORT=8080` (仅限 Docker Compose 部署，控制宿主机映射到外部的端口)
+- `BINGPAPER_SERVER_PORT=8080` (控制应用监听端口及容器内部端口)

+# BingPaper WebApp
+
+BingPaper 的前端 Web 应用，使用 Vue 3 + TypeScript + Vite 构建。
+
+> 💡 **性能优化提示**：已配置浏览器缓存优化，可减少 60-80% 带宽！  
+> 👉 后端配置：查看 [缓存配置快速参考](./CACHE_QUICK_REF.md)
+
+## 特性
+
+- ✨ Vue 3 组合式 API
+- 🎨 Tailwind CSS + shadcn-vue 组件库
+- 📦 TypeScript 类型支持
+- 🔧 完整的 API 客户端封装
+- 🚀 优化的构建配置
+- ⚡ 浏览器缓存优化（内容哈希 + 代码分割）
+- 🌐 支持自定义后端路径
+- 📁 自动输出到上级目录的 web 文件夹
+- 🔐 完整的管理后台系统（Token 管理、定时任务、系统配置）
+
+## 快速开始
+
+### 安装依赖
+
+```bash
+npm install
+```
+
+### 开发环境
+
+```bash
+npm run dev
+```
+
+开发服务器会在 `http://localhost:5173` 启动，并自动代理 `/api` 请求到后端服务器。
+
+### 构建生产版本
+
+```bash
+npm run build
+```
+
+构建产物会自动输出到项目上级目录的 `web` 文件夹，供 Go 服务器使用。
+
+### 预览构建结果
+
+```bash
+npm run preview
+```
+
+## 构建配置
+
+### 环境变量
+
+项目支持通过环境变量配置后端 API 路径：
+
+- `.env` - 默认配置
+- `.env.development` - 开发环境配置
+- `.env.production` - 生产环境配置
+
+修改 `VITE_API_BASE_URL` 来自定义后端 API 路径。
+
+### 输出目录
+
+构建产物输出到 `../web/`，目录结构：
+
+```
+web/
+├── index.html
+├── assets/
+│   ├── index-[hash].js
+│   └── index-[hash].css
+└── vite.svg
+```
+
+## API 使用
+
+项目提供了完整的 TypeScript API 客户端：
+
+```typescript
+import { bingPaperApi } from '@/lib/api-service'
+
+// 获取今日图片
+const meta = await bingPaperApi.getTodayImageMeta()
+
+// 获取图片列表
+const images = await bingPaperApi.getImages({ limit: 10 })
+```
+
+详细的 API 使用示例请参阅 [API_EXAMPLES.md](./API_EXAMPLES.md)
+
+## 构建说明
+
+详细的构建配置和部署说明请参阅 [BUILD.md](./BUILD.md)

+
+## 管理后台
+
+访问 `/admin/login` 进入管理后台登录页面。
+
+### 功能模块
+
+#### 1. Token 管理
+- 查看所有 API Token
+- 创建新的 Token（支持设置过期时间）
+- 启用/禁用 Token
+- 删除 Token
+
+#### 2. 定时任务管理
+- 手动触发图片抓取（可指定抓取天数）
+- 手动触发旧图片清理
+- 查看任务执行历史
+
+#### 3. 系统配置管理
+- **JSON 编辑模式**：直接编辑配置 JSON
+- **表单编辑模式**：通过友好的表单界面修改配置
+- 支持的配置项：
+  - 服务器配置（端口、基础 URL）
+  - API 模式（本地/重定向）
+  - 定时任务配置
+  - 数据库配置
+  - 存储配置（本地/S3/WebDAV）
+  - 图片保留策略
+  - Token 配置
+  - 日志配置
+  - 功能特性开关
+
+#### 4. 密码管理
+- 修改管理员密码
+- 安全退出登录
+
+### 安全特性
+- 基于 JWT Token 的身份验证
+- Token 过期自动跳转登录页
+- 路由守卫保护管理页面
+- 密码修改后强制重新登录
