Pour y parvenir, importez `JSONResponse` et renvoyez-y directement votre contenu, en définissant le `status_code` que vous souhaitez :

```Python hl_lines="4 25"
{!../../docs_src/additional_status_codes/tutorial001.py!}
```

/// warning | "Attention"

Lorsque vous renvoyez une `Response` directement, comme dans l'exemple ci-dessus, elle sera renvoyée directement.

对于这些情况，你可以使用一个`Response`参数。

## 使用 `Response` 参数

你可以在你的*路径操作函数*中声明一个`Response`类型的参数（就像你可以为cookies和头部做的那样）。

然后你可以在这个*临时*响应对象中设置`status_code`。

```Python hl_lines="1  9  12"
{!../../docs_src/response_change_status_code/tutorial001.py!}
```

然后你可以像平常一样返回任何你需要的对象（例如一个`dict`或者一个数据库模型）。如果你声明了一个`response_model`，它仍然会被用来过滤和转换你返回的对象。

## `StaticFiles` verwenden

* Importieren Sie `StaticFiles`.
* „Mounten“ Sie eine `StaticFiles()`-Instanz in einem bestimmten Pfad.

Sie könnten auch `from starlette.staticfiles import StaticFiles` verwenden.
