Added in FastAPI 0.135.0.

## What are Server-Sent Events? { #what-are-server-sent-events }

SSE is a standard for streaming data from the server to the client over HTTP.

尝试以下操作：

* 使用多个浏览器选项卡打开应用程序。
* 从这些选项卡中发送消息。
* 然后关闭其中一个选项卡。

这将引发 `WebSocketDisconnect` 异常，并且所有其他客户端都会收到类似以下的消息：

```
Client #1596980209979 left the chat
```

/// tip

上面的应用程序是一个最小和简单的示例，用于演示如何处理和向多个 WebSocket 连接广播消息。

但请记住，由于所有内容都在内存中以单个列表的形式处理，因此它只能在进程运行时工作，并且只能使用单个进程。

이 두 작업이 **가장 많은 시간을 소모**합니다. 이것이 FastAPI를 유지 관리하는 주요 작업입니다.

이 작업을 도와주신다면, **FastAPI 유지를 돕는 것**이며 FastAPI가 **더 빠르고 더 잘 발전하는 것**을 보장하는 것입니다. 🚀
