-# SSE (Server-Sent Events) 模块
-
-基于 Django REST Framework 的服务器推送事件实现。
-
-## 功能特性
-
-- ✅ 使用 DRF 处理请求和响应
-- ✅ 支持多种请求格式（JSON、Form Data、Multipart）
-- ✅ 自动数据验证和序列化
-- ✅ 异步支持，高并发处理
-- ✅ 心跳机制保持连接活跃
-- ✅ 自动清理断开的连接
-- ✅ 连接状态监控
-
-## API 端点
-
-### 1. 订阅 SSE 事件流
-
-**端点**: `GET /sse/`
-
-客户端连接此端点保持长连接，接收服务器推送的事件。
-
-**示例**:
-```bash
-curl -N http://localhost:8000/sse/
-```
-
-**JavaScript 示例**:
-```javascript
-const eventSource = new EventSource('http://localhost:8000/sse/');
-
-eventSource.onmessage = function(event) {
-    const data = JSON.parse(event.data);
-    console.log('收到消息:', data);
-};
-```
-
----
-
-### 2. 推送事件到所有客户端
-
-**端点**: `POST /sse/push/`
-
-向所有已连接的客户端广播消息。
-
-**请求参数**:
-- `message` (必填): 消息内容
-- `type` (可选): 事件类型，默认为 'message'
-
-**支持的请求格式**:
-
-#### JSON 格式
-```bash
-curl -X POST http://localhost:8000/sse/push/ \
-  -H "Content-Type: application/json" \
-  -d '{"message": "Hello, SSE!", "type": "notification"}'
-```
-
-#### Form Data 格式
-```bash
-curl -X POST http://localhost:8000/sse/push/ \
-  -d "message=Hello, SSE!" \
-  -d "type=notification"
-```
-
-#### Multipart Form Data
-```bash
-curl -X POST http://localhost:8000/sse/push/ \
-  -F "message=Hello, SSE!" \
-  -F "type=notification"
-```
-
-**响应示例**:
-```json
-{
-    "status": "success",
-    "message": "Event sent to 3 client(s)",
-    "clients": 3,
-    "sent": 3
-}
-```
-
----
-
-### 3. 获取连接状态
-
-**端点**: `GET /sse/status/`
-
-查询当前 SSE 服务器的状态和连接数。
-
-**示例**:
-```bash
-curl http://localhost:8000/sse/status/
-```
-
-**响应示例**:
-```json
-{
-    "status": "running",
-    "clients": 3,
-    "message": "SSE server is running with 3 active connection(s)"
-}
-```
-
-## 启动服务器
-
-使用 Uvicorn (ASGI 服务器) 启动：
-
-```bash
-# 开发环境
-uvicorn flower.asgi:application --reload --host 0.0.0.0 --port 8000
-
-# 生产环境
-uvicorn flower.asgi:application --host 0.0.0.0 --port 8000 --workers 4
-```
-
-## 测试
-
-打开 `sse_test.html` 在浏览器中测试：
-
-1. 点击"连接 SSE"建立连接
-2. 输入消息
-3. 点击"发送 (JSON)"或"发送 (Form Data)"测试不同格式
-4. 点击"获取连接状态"查看当前连接数
-5. 打开多个浏览器标签测试广播功能
-
-## Python 客户端示例
-
-```python
-import requests
-import sseclient  # pip install sseclient-py
-
-# 订阅事件
-response = requests.get('http://localhost:8000/sse/', stream=True)
-client = sseclient.SSEClient(response)
-
-for event in client.events():
-    print(f'收到消息: {event.data}')
-```
-
-## 技术实现
-
-- **异步视图**: 使用 `async def` 实现异步处理
-- **队列机制**: 每个连接对应一个 `asyncio.Queue`
-- **心跳**: 30 秒超时，自动发送心跳保持连接
-- **DRF 集成**: 使用 DRF 的 `@api_view` 和序列化器
-- **多格式支持**: 自动解析 JSON、Form Data、Multipart 等格式
-
-## 注意事项
-
-1. 必须使用 ASGI 服务器（如 Uvicorn、Daphne）运行
-2. 不支持使用传统的 WSGI 服务器（如 Gunicorn + WSGI）
-3. 如果使用 Nginx，需要禁用缓冲：`X-Accel-Buffering: no`
-4. SSE 使用 GET 请求，注意 CORS 配置
