你可以在你的*路径操作函数*中声明一个`Response`类型的参数（就像你可以为cookies做的那样）。

然后你可以在这个*临时*响应对象中设置头部。
```Python hl_lines="1  7-8"
{!../../docs_src/response_headers/tutorial002.py!}
```

然后你可以像平常一样返回任何你需要的对象（例如一个`dict`或者一个数据库模型）。如果你声明了一个`response_model`，它仍然会被用来过滤和转换你返回的对象。

**FastAPI**将使用这个临时响应来提取头部（也包括cookies和状态码），并将它们放入包含你返回的值的最终响应中，该响应由任何`response_model`过滤。

你也可以在依赖项中声明`Response`参数，并在其中设置头部（和cookies）。

## 直接返回 `Response`

import okhttp3.internal.connection.RealConnection

internal fun parseCookie(
  currentTimeMillis: Long,
  url: HttpUrl,
  setCookie: String,
): Cookie? = Cookie.parse(currentTimeMillis, url, setCookie)

internal fun cookieToString(
  cookie: Cookie,
  forObsoleteRfc2965: Boolean,
): String = cookie.toString(forObsoleteRfc2965)

internal fun addHeaderLenient(
  builder: Headers.Builder,
  line: String,

# Headers de Respuesta

## Usar un parámetro `Response`

Puedes declarar un parámetro de tipo `Response` en tu *función de operación de path* (de manera similar como se hace con las cookies).

Y entonces, podrás configurar las cookies en ese objeto de response *temporal*.

```Python hl_lines="1  7-8"
{!../../docs_src/response_headers/tutorial002.py!}
```

**FastAPI** usará essa resposta *temporária* para extrair os cabeçalhos (cookies e código de status também) e os colocará na resposta final que contém o valor que você retornou, filtrado por qualquer `response_model`.

Você também pode declarar o parâmetro `Response` em dependências e definir cabeçalhos (e cookies) nelas.

## Retornar uma `Response` diretamente

        .add("proxy-authorization", "chocolate")
        .add("cookie", "drink=coffee")
        .add("set-cookie", "accessory=sugar")
        .add("user-agent", "OkHttp")
        .build()
    assertThat(headers.toString()).isEqualTo(
      """
      |content-length: 99
      |authorization: ██
      |proxy-authorization: ██
      |cookie: ██
      |set-cookie: ██
      |user-agent: OkHttp
      |

  @Test @Disabled
  fun cookie() {
    val cookie: Cookie = Cookie.Builder().build()
    val name: String = cookie.name()
    val value: String = cookie.value()
    val persistent: Boolean = cookie.persistent()
    val expiresAt: Long = cookie.expiresAt()
    val hostOnly: Boolean = cookie.hostOnly()
    val domain: String = cookie.domain()
    val path: String = cookie.path()

**FastAPI** verwendet diese *vorübergehende* Response, um die Header (auch Cookies und Statuscode) zu extrahieren und fügt diese in die endgültige Response ein, die den von Ihnen zurückgegebenen Wert enthält, gefiltert nach einem beliebigen `response_model`.

Sie können den Parameter `Response` auch in Abhängigkeiten deklarieren und darin Header (und Cookies) festlegen.

## Eine `Response` direkt zurückgeben

**FastAPI** will use that *temporal* response to extract the headers (also cookies and status code), and will put them in the final response that contains the value you returned, filtered by any `response_model`.

You can also declare the `Response` parameter in dependencies, and set headers (and cookies) in them.

## Return a `Response` directly

You can also add headers when you return a `Response` directly.
