## Verbindungsabbrüche und mehreren Clients handhaben

Wenn eine WebSocket-Verbindung geschlossen wird, löst `await websocket.receive_text()` eine `WebSocketDisconnect`-Exception aus, die Sie dann wie in folgendem Beispiel abfangen und behandeln können.

=== "Python 3.9+"

    ```Python hl_lines="79-81"

## Handling disconnections and multiple clients

When a WebSocket connection is closed, the `await websocket.receive_text()` will raise a `WebSocketDisconnect` exception, which you can then catch and handle like in this example.

=== "Python 3.9+"

    ```Python hl_lines="79-81"
    {!> ../../../docs_src/websockets/tutorial003_py39.py!}

!!! tip
    注意，查询参数 `token` 将由依赖项处理。

通过这样，您可以连接 WebSocket，然后发送和接收消息：

## 处理断开连接和多个客户端

当 WebSocket 连接关闭时，`await websocket.receive_text()` 将引发 `WebSocketDisconnect` 异常，您可以捕获并处理该异常，就像本示例中的示例一样。

    ```Python hl_lines="79-81"
