# 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。

{* ../../docs_src/response_cookies/tutorial002.py hl[1,8:9] *}

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。

你也可以在depend中定义`Response`参数，并设置cookie和header。

            None,
            200,
            {"q_or_cookie": None},
        ),
    ],
)

    else:
        client.cookies.clear()
    response = client.get(path)
    assert response.status_code == expected_status
    assert response.json() == expected_response
