You can use Pydantic's model configuration to `forbid` any `extra` fields:

/// note | "技术细节"

`Cookie` 、`Path` 、`Query` 是**兄弟类**，都继承自共用的 `Param` 类。

注意，从 `fastapi` 导入的 `Query`、`Path`、`Cookie` 等对象，实际上是返回特殊类的函数。

///

/// info | "说明"

必须使用 `Cookie` 声明 cookie 参数，否则该参数会被解释为查询参数。

Se o cliente tentar enviar alguns **cookies extras**, eles receberão um retorno de **erro**.

Coitados dos banners de cookies com todo o seu esforço para obter o seu consentimento para a <abbr title="Isso é uma outra piada. Não preste atenção em mim. Beba um café com o seu cookie. ☕">API rejeitá-lo</abbr>. 🍪

/// note | "기술 세부사항"

`Cookie`는 `Path` 및 `Query`의 "자매"클래스입니다. 이 역시 동일한 공통 `Param` 클래스를 상속합니다.

`Query`, `Path`, `Cookie` 그리고 다른 것들은 `fastapi`에서 임포트 할 때, 실제로는 특별한 클래스를 반환하는 함수임을 기억하세요.

///

/// info | "정보"

쿠키를 선언하기 위해서는 `Cookie`를 사용해야 합니다. 그렇지 않으면 해당 매개변수를 쿼리 매개변수로 해석하기 때문입니다.
