Sie können eine `RedirectResponse` direkt zurückgeben:

```Python hl_lines="2  9"
{!../../../docs_src/custom_response/tutorial006.py!}
```

---

Oder Sie können sie im Parameter `response_class` verwenden:


```Python hl_lines="2  7  9"
{!../../../docs_src/custom_response/tutorial006b.py!}
```

Wenn Sie das tun, können Sie die URL direkt von Ihrer *Pfadoperation*-Funktion zurückgeben.

```Python hl_lines="2  7"
{!../../../docs_src/custom_response/tutorial001.py!}
```

!!! tip "豆知識"
    `ORJSONResponse` のほうが高速な代替かもしれません。

### `RedirectResponse`

HTTPリダイレクトを返します。デフォルトでは307ステータスコード (Temporary Redirect) となります。

```Python hl_lines="2  9"
{!../../../docs_src/custom_response/tutorial006.py!}
```

### `StreamingResponse`

```Python hl_lines="13  15"
{!../../../docs_src/custom_request_and_route/tutorial002.py!}
```

Wenn eine Exception auftritt, befindet sich die `Request`-Instanz weiterhin im Gültigkeitsbereich, sodass wir den Requestbody lesen und bei der Fehlerbehandlung verwenden können:

```Python hl_lines="16-18"
{!../../../docs_src/custom_request_and_route/tutorial002.py!}
```

```Python hl_lines="2  10"
{!../../../docs_src/custom_response/tutorial009.py!}
```

You can also use the `response_class` parameter:

```Python hl_lines="2  8  10"
{!../../../docs_src/custom_response/tutorial009b.py!}
```

In this case, you can return the file path directly from your *path operation* function.

## Custom response class

```Python hl_lines="7  21  23"
{!../../../docs_src/custom_response/tutorial004.py!}
```
