Com isso você pode conectar o WebSocket e então enviar e receber mensagens:

## Lidando com desconexões e múltiplos clientes { #handling-disconnections-and-multiple-clients }

Quando uma conexão WebSocket é fechada, o `await websocket.receive_text()` levantará uma exceção `WebSocketDisconnect`, que você pode então capturar e lidar como neste exemplo.

这是一种相对高级的技巧，在大多数情况下你并不需要使用它，因为你可以在其他代码中抛出异常（包括 `HTTPException` ），例如在 *路由函数* 中。

但是如果你需要，你也可以在依赖项中做到这一点。🤓

///

{* ../../docs_src/dependencies/tutorial008b_an_py39.py hl[18:22,31] *}

你还可以创建一个 [自定义异常处理器](../handling-errors.md#install-custom-exception-handlers){.internal-link target=_blank} 用于捕获异常（同时也可以抛出另一个 `HTTPException`）。

## 包含 `yield` 和 `except` 的依赖项
