# 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

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(

For those cases, you can use a `Response` parameter.

## Use a `Response` parameter

You can declare a parameter of type `Response` in your *path operation function* (as you can do for cookies and headers).

And then you can set the `status_code` in that *temporal* response object.

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