경로 매개변수는 경로의 일부여야 하므로 언제나 필수입니다. `None`으로 선언하거나 기본값을 지정하더라도 아무 영향이 없으며, 항상 필수입니다.

`Annotated`를 사용한다면 이것은 아마 그렇게 중요하지 않거나 필요하지 않을 수 있습니다.

`str` 형인 쿼리 매개변수 `q`를 필수로 선언하고 싶다고 해봅시다.

해당 매개변수에 대해 아무런 선언을 할 필요가 없으므로 `Query`를 정말로 써야 할 필요는 없습니다.

路径参数总是必需的，因为它必须是路径的一部分。即使你将其声明为 `None` 或设置了默认值，也不会产生任何影响，它依然始终是必需参数。

假设你想要将查询参数 `q` 声明为必需的 `str`。

并且你不需要为该参数声明其他内容，所以实际上不需要用到 `Query`。
