You can import it directly form `fastapi`:

```python
from fastapi import WebSocketDisconnect
```

::: fastapi.WebSocketDisconnect

## WebSockets - additional classes

Additional classes for handling WebSockets.

Provided directly by Starlette, but you can import it from `fastapi`:

```python
from fastapi.websockets import WebSocketDisconnect, WebSocketState
```

> Requests ist eines der am häufigsten heruntergeladenen Python-Packages aller Zeiten

Die Art und Weise, wie Sie es verwenden, ist sehr einfach. Um beispielsweise einen `GET`-Request zu machen, würden Sie schreiben:

```Python
response = requests.get("http://example.com/some/url")
```

Die entsprechende *Pfadoperation* der FastAPI-API könnte wie folgt aussehen:

```Python hl_lines="1"
@app.get("/some/url")
def read_url():

对具有子类型的模型属性也使用相同的标准语法。

因此，在我们的示例中，我们可以将 `tags` 明确地指定为一个「字符串列表」：

```Python hl_lines="12"

```

////

//// tab | Python 3.9+

```Python hl_lines="14"
{!> ../../docs_src/body_nested_models/tutorial002_py39.py!}
```

////

//// tab | Python 3.8+

```Python hl_lines="14"
{!> ../../docs_src/body_nested_models/tutorial002.py!}
```

**FastAPI** 知道在每种情况下该做什么以及如何复用同一对象，因此所有后台任务被合并在一起并且随后在后台运行：
