# Custom Response Classes - File, HTML, Redirect, Streaming, etc.

There are several custom response classes you can use to create an instance and return them directly from your *path operations*.

Read more about it in the [FastAPI docs for Custom Response - HTML, Stream, File, others](https://fastapi.tiangolo.com/advanced/custom-response/).

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

```python
from fastapi.responses import (
    FileResponse,

## Combinez les réponses prédéfinies et les réponses personnalisées

Vous voulez peut-être avoir des réponses prédéfinies qui s'appliquent à de nombreux *paramètre de chemin*, mais vous souhaitez les combiner avec des réponses personnalisées nécessaires à chaque *opération de chemin*.

## Дополнительная информация об ответах OpenAPI { #more-information-about-openapi-responses }

Чтобы увидеть, что именно можно включать в ответы, посмотрите эти разделы спецификации OpenAPI:

* <a href="https://github.com/OAI/OpenAPI-Specification/blob/master/versions/3.1.0.md#responses-object" class="external-link" target="_blank">Объект Responses OpenAPI</a>, он включает `Response Object`.

Você pode declarar um `response_model`, utilizando o código de status padrão `200` (ou um customizado caso você precise), e depois adicionar informações adicionais para esse mesmo retorno em `responses`, diretamente no esquema OpenAPI.

O **FastAPI** manterá as informações adicionais do `responses`, e combinará com o esquema JSON do seu modelo.

## 组合信息
您还可以联合接收来自多个位置的响应信息，包括 `response_model `、 `status_code` 和 `responses `参数。

您可以使用默认的状态码 `200` （或者您需要的自定义状态码）声明一个 `response_model `，然后直接在OpenAPI模式中在 `responses` 中声明相同响应的其他信息。

**FastAPI**将保留来自 `responses` 的附加信息，并将其与模型中的JSON Schema结合起来。

例如，您可以使用状态码 `404` 声明响应，该响应使用`Pydantic`模型并具有自定义的` description` 。

* <a href="https://github.com/OAI/OpenAPI-Specification/blob/master/versions/3.1.0.md#response-object" class="external-link" target="_blank">OpenAPI Response Object</a>, Sie können alles davon direkt in jede Response innerhalb Ihres `responses`-Parameter einfügen. Einschließlich `description`, `headers`, `content`...

## Response Adicional con `model` { #additional-response-with-model }

Puedes pasar a tus *decoradores de path operation* un parámetro `responses`.

Recibe un `dict`: las claves son los códigos de estado para cada response (como `200`), y los valores son otros `dict`s con la información para cada uno de ellos.

* <a href="https://github.com/OAI/OpenAPI-Specification/blob/master/versions/3.1.0.md#response-object" class="external-link" target="_blank">OpenAPI Response Object</a>, you can include anything from this directly in each response inside your `responses` parameter. Including `description`, `headers`, `content` (inside...

/// note | 기술적 세부사항

`from starlette.responses import Response` 또는 `from starlette.responses import JSONResponse`를 사용할 수도 있습니다.

**FastAPI**는 개발자의 편의를 위해 `fastapi.responses`로 동일한 `starlette.responses`를 제공합니다. 그러나 대부분의 응답은 Starlette에서 직접 제공됩니다.

또한 `Response`는 헤더와 쿠키를 설정하는 데 자주 사용되므로, **FastAPI**는 이를 `fastapi.Response`로도 제공합니다.
