+# 在线阅读功能部署说明
+
+## 后端部署步骤
+
+### 1. 数据库迁移
+
+在线阅读功能添加了以下数据库变更：
+
+**CrudBookModel 模型新增字段：**
+- `file`: 电子书文件字段（FileField）
+- `file_type`: 文件类型字段（CharField）
+
+**新增 ReadingProgress 模型：**
+- `user`: 用户外键
+- `book`: 图书外键
+- `location`: 阅读位置（CFI格式）
+- `progress`: 阅读进度百分比
+
+**执行迁移命令：**
+
+```bash
+cd django-vue3-admin-backend
+
+# 创建迁移文件
+python manage.py makemigrations crud_book
+
+# 执行迁移
+python manage.py migrate crud_book
+```
+
+### 2. 新增API接口
+
+**图书文件接口：**
+- `GET /api/CrudBookModelViewSet/{id}/file/` - 获取图书文件信息
+
+**阅读进度接口：**
+- `POST /api/reading-progress/` - 保存/更新阅读进度
+- `GET /api/reading-progress/by_book/?book_id={id}` - 获取指定图书的阅读进度
+- `GET /api/reading-progress/` - 获取当前用户所有阅读进度
+
+### 3. 配置检查
+
+确保 `settings.py` 中已配置：
+
+```python
+# 媒体文件配置
+MEDIA_URL = '/media/'
+MEDIA_ROOT = os.path.join(BASE_DIR, 'media')
+```
+
+确保主 `urls.py` 中已配置静态文件服务：
+
+```python
+from django.conf import settings
+from django.conf.urls.static import static
+
+urlpatterns = [
+    # ... 其他路由
+] + static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT)
+```
+
+## 前端部署步骤
+
+### 1. 安装依赖
+
+```bash
+cd django-vue3-admin-web
+
+# 使用yarn安装（推荐）
+yarn install
+
+# 或使用npm
+npm install --legacy-peer-deps
+```
+
+### 2. 配置检查
+
+已添加的文件：
+- `src/views/book/reader/index.vue` - 阅读器组件
+- `src/api/book/reader.ts` - API接口定义
+- `src/router/route.ts` - 路由配置（已添加 /book/reader）
+
+已修改的文件：
+- `src/views/crud_book/CrudBookModelViewSet/crud.tsx` - 添加"在线阅读"按钮
+
+### 3. 启动开发服务器
+
+```bash
+yarn dev
+# 或
+npm run dev
+```
+
+## 测试步骤
+
+### 1. 上传测试文件
+
+1. 准备一个EPUB格式的电子书文件
+2. 在图书管理页面，编辑或新增图书
+3. 上传EPUB文件到"电子书文件"字段
+4. 保存图书信息
+
+### 2. 测试在线阅读
+
+1. 在图书列表中找到已上传文件的图书
+2. 点击"在线阅读"按钮
+3. 验证阅读器是否正常加载
+4. 测试功能：
+   - 翻页（上一页/下一页）
+   - 目录导航
+   - 字体大小调整
+   - 阅读进度保存
+
+### 3. 测试阅读进度
+
+1. 阅读几页后关闭阅读器
+2. 重新打开同一本书
+3. 验证是否自动跳转到上次阅读位置
+
+## 常见问题
+
+### Q: 阅读器无法加载图书？
+
+**检查项：**
+1. 确认EPUB文件已正确上传
+2. 检查后端MEDIA配置是否正确
+3. 查看浏览器控制台错误信息
+4. 确认API接口返回正确的文件URL
+
+### Q: 阅读进度无法保存？
+
+**检查项：**
+1. 确认用户已登录
+2. 检查数据库迁移是否执行成功
+3. 查看后端日志是否有错误
+4. 确认ReadingProgress模型已创建
+
+### Q: 前端启动失败？
+
+**解决方案：**
+1. 删除 `node_modules` 和 `package-lock.json`
+2. 使用 `yarn install` 重新安装依赖
+3. 如果使用npm，添加 `--legacy-peer-deps` 参数
+
