## 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.

## Lidando com desconexões e múltiplos clientes

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.

{*../../docs_src/websockets/tutorial003_py39.py hl[79:81]*}

Para testar:

## 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.

//// tab | 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。

//// tab | Python 3.9+

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

////

クエリ `token` は依存パッケージによって処理されることに注意してください。

///

これにより、WebSocketに接続してメッセージを送受信できます。

<img src="/img/tutorial/websockets/image05.png">

## 切断や複数クライアントへの対応

WebSocket接続が閉じられると、 `await websocket.receive_text()` は例外 `WebSocketDisconnect` を発生させ、この例のようにキャッチして処理することができます。

```Python hl_lines="81-83"
{!../../docs_src/websockets/tutorial003.py!}
```

試してみるには、

* いくつかのブラウザタブでアプリを開きます。
* それらのタブでメッセージを記入してください。
