**FastAPI** will use that *temporal* response to extract the cookies (also headers 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 cookies (and headers) in them.

## Return a `Response` directly

You can also create cookies when returning a `Response` directly in your code.

# 响应Cookies

## 使用 `Response` 参数

你可以在 *路径函数* 中定义一个类型为 `Response`的参数，这样你就可以在这个临时响应对象中设置cookie了。

```Python hl_lines="1  8-9"
{!../../docs_src/response_cookies/tutorial002.py!}
```

而且你还可以根据你的需要响应不同的对象，比如常用的 `dict`，数据库model等。

如果你定义了 `response_model`，程序会自动根据`response_model`来过滤和转换你响应的对象。

**FastAPI** 会使用这个 *临时* 响应对象去装在这些cookies信息 (同样还有headers和状态码等信息), 最终会将这些信息和通过`response_model`转化过的数据合并到最终的响应里。

**FastAPI** usará essa resposta *temporária* para extrair os cookies (também os cabeçalhos e código de status) 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 cookies (e cabeçalhos) nelas.

## Retornando uma `Response` diretamente

Você também pode criar cookies ao retornar uma `Response` diretamente no seu código.

**FastAPI** verwendet diese *vorübergehende* Response, um die Cookies (auch Header 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 `Response`-Parameter auch in Abhängigkeiten deklarieren und darin Cookies (und Header) setzen.

## Eine `Response` direkt zurückgeben

 & `Response` 💪 ⚙️ 🛎 ⚒ 🎚 & 🍪, **FastAPI** 🚚 ⚫️ `fastapi.Response`.

///

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

## Proibir Cookies Adicionais

Em alguns casos especiais (provavelmente não muito comuns), você pode querer **restringir** os cookies que você deseja receber.

But even if you **fill the data** and click "Execute", because the docs UI works with **JavaScript**, the cookies won't be sent, and you will see an **error** message as if you didn't write any values.

///

## Forbid Extra Cookies

In some special use cases (probably not very common), you might want to **restrict** the cookies that you want to receive.

////

/// note | "Технические детали"

`Cookie` - это класс, родственный `Path` и `Query`. Он также наследуется от общего класса `Param`.

Но помните, что когда вы импортируете `Query`, `Path`, `Cookie` и другое из `fastapi`, это фактически функции, которые возвращают специальные классы.
