## FastAPI-Responses

from starlette.responses import HTMLResponse as HTMLResponse  # noqa
from starlette.responses import JSONResponse as JSONResponse  # noqa
from starlette.responses import PlainTextResponse as PlainTextResponse  # noqa
from starlette.responses import RedirectResponse as RedirectResponse  # noqa

## FastAPI Responses

```Python hl_lines="3-4  9-11  22"
{!../../../docs_src/handling_errors/tutorial004.py!}
```

!!! note "Технические детали"
    Можно также использовать `from starlette.responses import PlainTextResponse`.

    **FastAPI** предоставляет тот же `starlette.responses`, что и `fastapi.responses`, просто для удобства разработчика. Однако большинство доступных ответов поступает непосредственно из Starlette.

例如，只为错误返回纯文本响应，而不是返回 JSON 格式的内容：

```Python hl_lines="3-4  9-11  22"
{!../../../docs_src/handling_errors/tutorial004.py!}

```

!!! note "技术细节"

    还可以使用 `from starlette.responses import PlainTextResponse`。

    **FastAPI** 提供了与 `starlette.responses` 相同的 `fastapi.responses` 作为快捷方式，但大部分响应都可以直接从 Starlette 导入。


### 使用 `RequestValidationError` 的请求体

`RequestValidationError` 包含其接收到的无效数据请求的 `body` 。

```Python hl_lines="3-4  9-11  22"
{!../../../docs_src/handling_errors/tutorial004.py!}
```

!!! note "Technical Details"
    You could also use `from starlette.responses import PlainTextResponse`.

    **FastAPI** provides the same `starlette.responses` as `fastapi.responses` just as a convenience for you, the developer. But most of the available responses come directly from Starlette.

```Python hl_lines="1  18"
{!../../../docs_src/response_directly/tutorial002.py!}
```

### `HTMLResponse`

如上文所述，接受文本或字节并返回 HTML 响应。

### `PlainTextResponse`

接受文本或字节并返回纯文本响应。

```Python hl_lines="2  7  9"
{!../../../docs_src/custom_response/tutorial005.py!}
```

### `JSONResponse`

接受数据并返回一个 `application/json` 编码的响应。

```Python hl_lines="3-4  9-11  22"
{!../../../docs_src/handling_errors/tutorial004.py!}
```

!!! note "Detalhes Técnicos"
    Você pode usar `from starlette.responses import PlainTextResponse`.

    **FastAPI** disponibiliza o mesmo `starlette.responses` como `fastapi.responses`, como conveniência a você, desenvolvedor. Contudo, a maior parte das respostas disponíveis vem diretamente do Starlette.
