You can import them directly from `fastapi.responses`:

```python
from fastapi.responses import (
    FileResponse,
    HTMLResponse,
    JSONResponse,
    ORJSONResponse,
    PlainTextResponse,
    RedirectResponse,
    Response,
    StreamingResponse,
    UJSONResponse,
)
```

## FastAPI Responses

There are a couple of custom FastAPI response classes, you can use them to optimize JSON performance.

```

!!! tip "Tipp"
    Möglicherweise ist `ORJSONResponse` eine schnellere Alternative.

### `RedirectResponse`

Gibt eine HTTP-Weiterleitung (HTTP-Redirect) zurück. Verwendet standardmäßig den Statuscode 307 – Temporäre Weiterleitung (Temporary Redirect).

Sie können eine `RedirectResponse` direkt zurückgeben:

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

---

{!../../../docs_src/custom_response/tutorial001.py!}
```

!!! tip
    It's possible that `ORJSONResponse` might be a faster alternative.

### `RedirectResponse`

Returns an HTTP redirect. Uses a 307 status code (Temporary Redirect) by default.

You can return a `RedirectResponse` directly:

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

---

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

!!! tip
    ⚫️ 💪 👈 `ORJSONResponse` 💪 ⏩ 🎛.

### `RedirectResponse`

📨 🇺🇸🔍 ❎. ⚙️ 3️⃣0️⃣7️⃣ 👔 📟 (🍕 ❎) 🔢.

👆 💪 📨 `RedirectResponse` 🔗:

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

⚖️ 👆 💪 ⚙️ ⚫️ `response_class` 🔢:

And tools will also be happy because both `RedirectResponse` and `JSONResponse` are subclasses of `Response`, so the type annotation is correct.

### Annotate a Response Subclass

You can also use a subclass of `Response` in the type annotation:

```Python hl_lines="8-9"
{!> ../../../docs_src/response_model/tutorial003_03.py!}
```

                Read more about it in the
                [FastAPI docs for Custom Response - HTML, Stream, File, others](https://fastapi.tiangolo.com/advanced/custom-response/#redirectresponse).
                """
            ),
        ] = Default(JSONResponse),
        name: Annotated[
            Optional[str],
            Doc(
                """

    在处理某些边缘情况时，`ujson` 不如 Python 的内置实现那么谨慎。

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

!!! tip "小贴士"
    `ORJSONResponse` 可能是一个更快的选择。

### `RedirectResponse`

返回 HTTP 重定向。默认情况下使用 307 状态代码（临时重定向）。

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

### `StreamingResponse`

采用异步生成器或普通生成器/迭代器，然后流式传输响应主体。

```

Dieser einfache Anwendungsfall wird automatisch von FastAPI gehandhabt, weil die Annotation des Rückgabetyps die Klasse (oder eine Unterklasse von) `Response` ist.

Und Tools werden auch glücklich sein, weil sowohl `RedirectResponse` als auch `JSONResponse` Unterklassen von `Response` sind, die Typannotation ist daher korrekt.

### Eine Unterklasse von Response annotieren

```

Это поддерживается FastAPI по-умолчанию, т.к. аннотация проставлена в классе (или подклассе) `Response`.

И ваши помощники разработки также будут счастливы, т.к. оба класса `RedirectResponse` и `JSONResponse` являются подклассами `Response`. Таким образом мы получаем корректную аннотацию типа.

### Подкласс Response в аннотации типа

Вы также можете указать подкласс `Response` в аннотации типа:
