Si necesitas marcar una *path operation* como <abbr title="obsoleta, se recomienda no usarla">deprecated</abbr>, pero sin eliminarla, pasa el parámetro `deprecated`:

{* ../../docs_src/path_operation_configuration/tutorial006_py39.py hl[16] *}

Se marcará claramente como deprecado en la documentación interactiva:

<img src="/img/tutorial/path-operation-configuration/image04.png">

Se você precisar marcar uma *operação de rota* como <abbr title="obsoleta, recomendada não usá-la">descontinuada</abbr>, mas sem removê-la, passe o parâmetro `deprecated`:

{* ../../docs_src/path_operation_configuration/tutorial006_py39.py hl[16] *}

Ela será claramente marcada como descontinuada nas documentações interativas:

Hier ist eine kleine Vorschau, wie Sie Strawberry mit FastAPI integrieren können:

{* ../../docs_src/graphql_/tutorial001_py39.py hl[3,22,25] *}

Weitere Informationen zu Strawberry finden Sie in der <a href="https://strawberry.rocks/" class="external-link" target="_blank">Strawberry-Dokumentation</a>.

{* ../../docs_src/templates/tutorial001_py39.py hl[4,11,15:18] *}

/// note

Before FastAPI 0.108.0, Starlette 0.29.0, the `name` was the first parameter.

//// tab | Pydantic v2

{* ../../docs_src/settings/tutorial001_py39.py hl[2,5:8,11] *}

//// tab | Pydantic v1

/// info | Información

En Pydantic v1 importarías `BaseSettings` directamente desde `pydantic` en lugar de desde `pydantic_settings`.

## 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。

{* ../../docs_src/websockets/tutorial003_py39.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。

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
```

You can use all the same validation features and tools you use for Pydantic models, like different data types and additional validations with `Field()`.

{* ../../docs_src/settings/tutorial001_py39.py hl[2,5:8,11] *}

/// tip

If you want something quick to copy and paste, don't use this example, use the last one below.
