+# JSON Serializer 用法文档
+
+## 概述
+
+`json_serializer` 是一个通用的JSON序列化工具，用于处理Python中常见的非JSON序列化类型，如`datetime`、`date`、`time`、`ObjectId`等。
+
+## 支持的类型
+
+- `datetime`: 转换为ISO格式字符串
+- `date`: 转换为ISO格式字符串
+- `time`: 转换为ISO格式字符串
+- `ObjectId`: 转换为字符串
+- `bytes`: 转换为UTF-8字符串
+- `set`/`frozenset`: 转换为列表
+- 其他不可序列化类型: 转换为字符串表示
+
+## 安装位置
+
+位于 `apps/utils/json_serializer.py`
+
+## 使用方法
+
+### 导入
+
+```python
+from apps.utils.json_serializer import json_serialize, json_serialize_dict, JSONEncoder
+```
+
+### 函数说明
+
+1. **json_serialize(obj)**: 将对象序列化为JSON字符串
+   - 参数: `obj` - 要序列化的对象
+   - 返回: JSON字符串
+
+2. **json_serialize_dict(obj)**: 将对象转换为可JSON序列化的字典
+   - 参数: `obj` - 要序列化的对象
+   - 返回: 可JSON序列化的字典
+
+3. **JSONEncoder**: 自定义JSON编码器类，可直接用于`json.dumps()`
+
+### 示例
+
+#### 基本使用
+
+```python
+from datetime import datetime
+from apps.utils.json_serializer import json_serialize_dict
+
+# 创建包含datetime的字典
+data = {
+    "user_id": "test_user",
+    "updated_at": datetime.now(),
+    "scores": [85, 90, 95]
+}
+
+# 序列化
+serialized = json_serialize_dict(data)
+print(serialized)
+# 输出: {"user_id": "test_user", "updated_at": "2025-12-10T15:30:45.123456", "scores": [85, 90, 95]}
+```
+
+#### 在API请求中使用
+
+```python
+import requests
+from apps.utils.json_serializer import json_serialize_dict
+
+# 准备请求数据
+data = {
+    "user_id": "test_user",
+    "updated_at": datetime.now(),
+    "progress": {"chapter1": "completed", "chapter2": "in_progress"}
+}
+
+# 序列化数据
+serialized_data = json_serialize_dict(data)
+
+# 发送请求
+response = requests.post(
+    "https://api.example.com/upload",
+    json=serialized_data,
+    headers={"Content-Type": "application/json"}
+)
+```
+
+#### 直接使用JSONEncoder
+
+```python
+import json
+from datetime import datetime
+from apps.utils.json_serializer import JSONEncoder
+
+# 创建数据
+data = {"updated_at": datetime.now()}
+
+# 使用自定义编码器
+json_str = json.dumps(data, cls=JSONEncoder, ensure_ascii=False)
+print(json_str)
+# 输出: {"updated_at": "2025-12-10T15:30:45.123456"}
+```
+
+## 应用场景
+
+1. API请求中的数据序列化
+2. 保存数据到文件或数据库
+3. 跨服务数据传输
+4. 日志记录中的复杂对象序列化
+
+## 注意事项
+
+- 对于自定义对象，会尝试序列化其`__dict__`属性
+- 对于无法序列化的类型，会转换为字符串表示
+- 确保导入路径正确，特别是在不同模块中使用时
