## 禁止额外的 Cookie

在某些特殊使用情况下（可能并不常见），您可能希望**限制**您想要接收的 cookie。

您的 API 现在可以控制自己的 <abbr title="顺带一提，这是一个笑话。它与 cookie 同意无关，但现在连API都能拒绝那些可怜的 cookie，真是太有意思了。来，吃块小饼干（cookie）吧。🍪">cookie 同意</abbr>。🤪🍪

您可以使用 Pydantic 的模型配置来禁止（ `forbid` ）任何额外（ `extra` ）字段：

{* ../../docs_src/cookie_param_models/tutorial002_an_py39.py hl[10] *}

如果客户尝试发送一些**额外的 cookie**，他们将收到**错误**响应。

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