# `Response` class

You can declare a parameter in a *path operation function* or dependency to be of type `Response` and then you can set data for the response like headers or cookies.

You can also use it directly to create an instance of it and return it from your *path operations*.

You can import it directly from `fastapi`:

```python
from fastapi import Response
```

    }

    internal constructor(response: Response) {
      this.request = response.request
      this.protocol = response.protocol
      this.code = response.code
      this.message = response.message
      this.handshake = response.handshake
      this.headers = response.headers.newBuilder()
      this.body = response.body
      this.socket = response.socket
      this.networkResponse = response.networkResponse

# Headers de Response { #response-headers }

## Usa un parámetro `Response` { #use-a-response-parameter }

Puedes declarar un parámetro de tipo `Response` en tu *path operation function* (como puedes hacer para cookies).

Y luego puedes establecer headers en ese objeto de response *temporal*.

package jcifs.util.transport;

/**
 * Interface for transport response messages.
 * This interface represents responses received from network transports.
 */
public interface Response extends Message {

    /**
     * Checks if the response has been received.
     *
     * @return whether the response is received
     */
    boolean isReceived();

    /**
     * Set received status

But you can return a `JSONResponse` directly from your *path operations*.

It might be useful, for example, to return custom headers or cookies.

## Return a `Response` { #return-a-response }

In fact, you can return any `Response` or any sub-class of it.

/// tip

`JSONResponse` itself is a sub-class of `Response`.

///

直接返回响应可能会有用处，比如返回自定义的响应头和 cookies。

## 返回 `Response`

事实上，你可以返回任意 `Response` 或者任意 `Response` 的子类。

/// tip | 小贴士

`JSONResponse` 本身是一个 `Response` 的子类。

///

当你返回一个 `Response` 时，**FastAPI** 会直接传递它。

**FastAPI** 不会用 Pydantic 模型做任何数据转换，不会将响应内容转换成任何类型，等等。

这种特性给你极大的可扩展性。你可以返回任何数据类型，重写任何数据声明或者校验，等等。

## 在 `Response` 中使用 `jsonable_encoder`

由于 **FastAPI** 并未对你返回的 `Response` 做任何改变，你必须确保你已经准备好响应内容。

예를 들어, 사용자 정의 헤더나 쿠키를 반환해야 하는 경우에 유용할 수 있습니다.

## `Response` 반환하기

사실, `Response` 또는 그 하위 클래스를 반환할 수 있습니다.

/// tip

`JSONResponse` 자체도 `Response`의 하위 클래스입니다.

///

그리고 `Response`를 반환하면 **FastAPI**가 이를 그대로 전달합니다.

Pydantic 모델로 데이터 변환을 수행하지 않으며, 내용을 다른 형식으로 변환하지 않습니다.

이로 인해 많은 유연성을 얻을 수 있습니다. 어떤 데이터 유형이든 반환할 수 있고, 데이터 선언이나 유효성 검사를 재정의할 수 있습니다.

## `Response`에서 `jsonable_encoder` 사용하기

package org.codelibs.fess.suggest.request;

/**
 * The Response interface serves as a marker interface for all response types
 * in the suggestion system. Implementations of this interface are used to
 * encapsulate the results of various operations and queries within the system.
 *
 * <p>Classes implementing this interface should provide specific details and
 * data relevant to the type of response they represent.</p>
 */
public interface Response {

因此，**FastAPI** 将会负责过滤掉未在输出模型中声明的所有数据（使用 Pydantic）。

## 在文档中查看

当你查看自动化文档时，你可以检查输入模型和输出模型是否都具有自己的 JSON Schema：

并且两种模型都将在交互式 API 文档中使用：

## 响应模型编码参数

你的响应模型可以具有默认值，例如：
