## 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.

{* ../../docs_src/websockets_/tutorial003_py310.py hl[79:81] *}

Para testar:

## Обробка відключень і кількох клієнтів { #handling-disconnections-and-multiple-clients }

Коли з'єднання WebSocket закривається, `await websocket.receive_text()` підніме виняток `WebSocketDisconnect`, який ви можете перехопити й обробити, як у цьому прикладі.

{* ../../docs_src/websockets_/tutorial003_py310.py hl[79:81] *}

Щоб спробувати:

## Manejar desconexiones y múltiples clientes { #handling-disconnections-and-multiple-clients }

Cuando una conexión de WebSocket se cierra, el `await websocket.receive_text()` lanzará una excepción `WebSocketDisconnect`, que puedes capturar y manejar como en este ejemplo.

{* ../../docs_src/websockets_/tutorial003_py310.py hl[79:81] *}

Para probarlo:

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

## Verbindungsabbrüche und mehrere Clients handhaben { #handling-disconnections-and-multiple-clients }

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.

{* ../../docs_src/websockets_/tutorial003_py310.py hl[79:81] *}

Zum Ausprobieren:

///

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 { #handling-disconnections-and-multiple-clients }

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。

{* ../../docs_src/websockets_/tutorial003_py310.py hl[79:81] *}

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。
