+# 书籍API文档
+
+## 概述
+
+这是一套基于SQLite数据库的书籍管理API，提供书籍列表、目录、页面内容查询等功能。
+
+## 快速开始
+
+### 1. 数据导入
+
+首先需要将JSON数据导入到SQLite数据库：
+
+```bash
+python import_book_data.py
+```
+
+执行成功后，会在当前目录生成 `books.db` 文件。
+
+### 2. 启动应用
+
+```bash
+python app.py
+```
+
+应用默认运行在 `http://localhost:7860`
+
+## API端点
+
+### 基础信息
+
+- **Base URL**: `http://localhost:7860/api/v2`
+- **返回格式**: JSON
+- **编码**: UTF-8
+
+---
+
+### 1. 获取书籍列表
+
+获取所有可用的书籍。
+
+**请求**
+
+```
+GET /api/v2/books
+```
+
+**响应示例**
+
+```json
+{
+  "success": true,
+  "count": 1,
+  "books": [
+    {
+      "book_id": 1,
+      "book_name": "书籍ID 10242",
+      "source_file": "book_10242.json",
+      "total_pages": 64,
+      "created_at": "2024-10-16 12:00:00",
+      "updated_at": "2024-10-16 12:00:00"
+    }
+  ]
+}
+```
+
+---
+
+### 2. 获取书籍信息
+
+获取指定书籍的详细信息。
+
+**请求**
+
+```
+GET /api/v2/books/{book_id}
+```
+
+**参数**

+
+### 2. pages.json - 页面详细内容
+
+**用途**: 存储每一页的详细内容，包括图片路径、文本片段、音频资源、坐标信息等。
+
+**数据结构**:
+
+```json
+[
+  {
+    "pageId": 2111,                       // 页面ID（唯一标识）

+      // ... 更多片段
+    ]
+  }
+  // ... 更多页面
+]
+```
+
+**关键说明**:
+
+- **coordinate**: 坐标系统采用相对坐标（0-1），便于适配不同分辨率
+  - `x`, `y`: 文本框左上角相对位置
+  - `width`, `height`: 文本框的相对宽高
+  
+- **音频文件命名规则**: `page_{页码:3位}_piece_{片段索引:2位}.mp3`
+  - 例如: `page_002_piece_00.mp3` 表示第2页第0个片段
+
+**数据库表设计建议**:
+
+```sql
+-- 页面表
+CREATE TABLE book_pages (
+    page_id BIGINT PRIMARY KEY,
+    book_id BIGINT,
+    page_number INT,
+    origin_img_url VARCHAR(500),

+    piece_order INT,  -- 片段在页面中的顺序
+    INDEX idx_page (page_id),
+    FOREIGN KEY (page_id) REFERENCES book_pages(page_id)
+);
+```
+
+---
+
+### 3. catalog.json - 书籍目录结构
+
+**用途**: 存储书籍的章节目录信息，支持层级结构（通过 ParentID）。
+
+**数据结构**:
+
+```json
+{
+  "catalog": [
+    {
+      "CatalogID": 1,                     // 目录项ID

+    }
+    // ... 更多目录项
+  ],
+  "start_page": 1,                        // 书籍起始页
+  "end_page": 73                          // 书籍结束页
+}
+```
+
+**数据库表设计建议**:
+
+```sql
+CREATE TABLE book_catalogs (
+    catalog_id BIGINT PRIMARY KEY,
+    book_id BIGINT,
+    catalog_name VARCHAR(200),
+    catalog_name_cn VARCHAR(200),

+    FOREIGN KEY (book_id) REFERENCES books(market_book_id)
+);
+```
+
+---
+
+### 4. images/ - 页面图片资源
+
+**目录结构**:
+
+```
+images/
+├── page_001.jpg          # 第1页图片
+├── page_002.jpg          # 第2页图片
+├── ...
+└── thumbnails/           # 缩略图目录
+    ├── page_002_thumb.jpg
+    └── ...
+```
+
+**文件命名规则**:
+- 页面图片: `page_{页码:3位}.jpg`
+- 缩略图: `page_{页码:3位}_thumb.jpg`
+
+**存储建议**:
+- 推荐使用对象存储（如阿里云OSS、腾讯云COS、AWS S3）
+- 也可使用本地文件系统 + Nginx 提供静态文件服务
+- 数据库中存储相对路径，通过配置拼接完整URL
+
+---
+
+### 5. audios/ - 音频资源
+
+**目录结构**:
+
+```
+audios/
+├── page_002_piece_00.mp3

+## 🚀 API 接口开发指南
+
+### RESTful API 设计
+
+#### 1. 书籍列表接口
+
+**请求**:
+```http
+GET /api/books?grade_id=40&subject_id=167070462398963715&page=1&page_size=20
+```
+
+**响应**:
+```json
+{
+  "code": 0,
+  "message": "success",
+  "data": {
+    "total": 30,
+    "page": 1,
+    "page_size": 20,
+    "books": [
+      {
+        "book_id": 168,
+        "book_name": "一年级上册",
+        "cover": "https://cdn.example.com/168_一年级上册/images/page_001.jpg",

+        "max_page": 73
+      }
+    ]
+  }
+}
+```
+
+**Python 实现 (FastAPI)**:
+```python
+from fastapi import FastAPI, Query
+from typing import Optional
+import pymysql
+
+app = FastAPI()

+```
+
+### 步骤 2: 安装依赖
+
+```bash
+pip install flask flask-cors
+```
+
+### 步骤 3: 准备数据
+
+确保 `books_api_data` 目录在项目根目录下：
+
+```
+/data/zhangl/code/hf/point/
+└── books_api_data/
+    ├── 168_一年级上册/
+    ├── 169_二年级上册/
+    └── ...
+```
+
+### 步骤 4: 导入数据到数据库
+
+```bash
+# 导入所有书籍数据
+python3 import_book_data.py books_api_data
+```
+
+预期输出：
+```
+📦 创建数据库: books.db
+✅ 数据库结构创建成功

+- **阅读某本书**: http://localhost:7860/reader?book_id=168
+
+## 📖 使用说明
+
+### 书籍目录页面
+
+1. 浏览所有可用的教材
+2. 使用搜索框搜索教材
+3. 点击教材卡片进入阅读页面
+
+### 阅读页面
+
+1. **点读功能**: 点击页面上的文本片段播放音频
+2. **翻译切换**: 点击"翻译"按钮显示/隐藏中文翻译

+
+## 🔧 常见问题
+
+### 1. 数据导入失败
+
+**问题**: `❌ 错误: 数据目录不存在: books_api_data`
+
+**解决**: 
+- 确保 `books_api_data` 目录在项目根目录下
+- 检查目录中是否有书籍数据
+
+### 2. 页面图片不显示
+
+**问题**: 页面加载后图片不显示
+
+**解决**:
+- 检查 `books_api_data/xxx/images/` 目录是否存在
+- 检查图片文件命名是否正确（格式：`page_001.jpg`）
+- 查看浏览器控制台错误信息
+
+### 3. 音频无法播放
+
+**问题**: 点击文本片段后音频不播放
+
+**解决**:
+- 检查 `books_api_data/xxx/audios/` 目录是否存在
+- 检查音频文件是否存在
+- 确保浏览器支持 MP3 格式
+- 检查浏览器是否允许自动播放音频
+
+### 4. 端口被占用
+
+**问题**: `Address already in use`
+
+**解决**:
+```bash
+# 查找占用7860端口的进程
+lsof -i:7860
+
+# 或者使用其他端口
+export PORT=8080
+python3 app.py
+```
+
+### 5. 重新导入数据
+
+如果需要重新导入所有数据：
+
+```bash
+# 删除数据库并重新导入
+python3 import_book_data.py books_api_data --recreate
+```
+
+## 📊 数据统计
+
+查看已导入的数据统计：
+
+```bash
+# 运行验证脚本
+python3 import_book_data.py --verify-only
+```
+
+或者访问 API:
+```bash
+curl http://localhost:7860/api/v2/statistics
+```
+
+## 🔍 API 测试
+
+### 获取书籍列表
+```bash
+curl http://localhost:7860/api/v2/books
+```
+
+### 获取书籍详情
+```bash
+curl http://localhost:7860/api/v2/books/168
+```
+
+### 获取页面内容
+```bash
+curl http://localhost:7860/api/v2/books/168/pages/2
+```
+
+### 搜索内容
+```bash
+curl "http://localhost:7860/api/v2/books/168/search?keyword=hello"
+```
+
+## 🎯 下一步
+

+## 🔧 开发调试
+
+### 启用调试模式
+
+```bash
+export FLASK_DEBUG=True
+python3 app.py
+```
+
+### 查看日志
+
+应用日志存储在 `logs/app.log`
+
+### 数据库操作
+
+使用 `db_manager.py` 提供的数据库管理器：
+
+```python
+from db_manager import get_db_instance
+
+db = get_db_instance('books.db')
+
+# 获取所有书籍
+books = db.get_all_books()
+
+# 搜索内容
+results = db.search_content(book_id=168, keyword='hello', limit=20)
+
+# 获取统计信息
+stats = db.get_overall_statistics()
+```
+
+## 📝 数据格式说明
+
+### 坐标系统
+文本片段的坐标使用相对坐标（0-1范围）：
+```json
+{
+  "coordinate": {
+    "x": 0.0482,      // 左上角X坐标（相对于图片宽度）
+    "y": 0.0357,      // 左上角Y坐标（相对于图片高度）
+    "width": 0.3195,  // 宽度（相对于图片宽度）
+    "height": 0.0982  // 高度（相对于图片高度）
+  }
+}
+```
+
+### 资源路径
+资源路径采用相对路径格式：
+```
+168_一年级上册/images/page_001.jpg
+168_一年级上册/audios/page_002_piece_00.mp3
+```
+
+实际访问时会自动拼接为：
+```
+books_api_data/168_一年级上册/images/page_001.jpg
+books_api_data/168_一年级上册/audios/page_002_piece_00.mp3
+```
+
+## 🐛 故障排除
+
+### 数据库导入失败
+- 检查 books_api_data 目录是否存在
+- 确保每个书籍目录包含 book_info.json、pages.json
+- 检查 db_schema.sql 文件是否存在
+
+### 页面加载失败
+- 检查数据库是否正确导入
+- 查看浏览器控制台是否有错误
+- 检查 books_api_data 目录下的资源文件是否完整
+
+### 音频播放失败
+- 检查音频文件路径是否正确
+- 确保浏览器支持 MP3 格式
+- 查看浏览器控制台错误信息
