`Cookie` це "сестра" класів `Path` і `Query`. Вони наслідуються від одного батьківського класу `Param`.
Але пам'ятайте, що коли ви імпортуєте `Query`, `Path`, `Cookie` та інше з `fastapi`, це фактично функції, що повертають спеціальні класи.

/// note | "Technical Details"

`Cookie` is a "sister" class of `Path` and `Query`. It also inherits from the same common `Param` class.

But remember that when you import `Query`, `Path`, `Cookie` and others from `fastapi`, those are actually functions that return special classes.

def test(path, cookies, expected_status, expected_response):

    client = TestClient(app, cookies=cookies)
    response = client.get(path)
    assert response.status_code == expected_status
    assert response.json() == expected_response

# Cookie-Parameter

So wie `Query`- und `Path`-Parameter können Sie auch <abbr title='Cookie – „Keks“: Mechanismus, der kurze Daten in Textform im Browser des Benutzers speichert und abfragt'>Cookie</abbr>-Parameter definieren.

## `Cookie` importieren

Importieren Sie zuerst `Cookie`:

/// note | Detalhes Técnicos

`Cookie` é uma classe "irmã" de `Path` e `Query`. Ela também herda da mesma classe em comum `Param`.

Mas lembre-se que quando você importa `Query`, `Path`, `Cookie` e outras de `fastapi`, elas são na verdade funções que retornam classes especiais.

///

/// info | Informação

client = TestClient(app)


def test_path_operation():
    response = client.post("/cookie/")
    assert response.status_code == 200, response.text
    assert response.json() == {"message": "Come to the dark side, we have cookies"}

client = TestClient(app)


def test_path_operation():
    response = client.post("/cookie-and-object/")
    assert response.status_code == 200, response.text
    assert response.json() == {"message": "Come to the dark side, we have cookies"}

Para esos casos, puedes usar un parámetro `Response`.

## Usar un parámetro `Response`

Puedes declarar un parámetro de tipo `Response` en tu *función de la operación de path* (como puedes hacer para cookies y headers).

Y luego puedes establecer el `status_code` en ese objeto de respuesta *temporal*.

```Python hl_lines="1  9  12"
{!../../docs_src/response_change_status_code/tutorial001.py!}
```

            {"hidden_cookie": "somevalue"},
            200,
            {"hidden_cookie": "somevalue"},
        ),
    ],
)
def test_hidden_cookie(path, cookies, expected_status, expected_response):
    client = TestClient(app, cookies=cookies)
    response = client.get(path)
    assert response.status_code == expected_status
    assert response.json() == expected_response


@pytest.mark.parametrize(

对于这些情况，你可以使用一个`Response`参数。

## 使用 `Response` 参数

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和头部做的那样）。

然后你可以在这个*临时*响应对象中设置`status_code`。

```Python hl_lines="1  9  12"
{!../../docs_src/response_change_status_code/tutorial001.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状态码（也包括cookies和头部），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。
