/// note | "Technische Details"

`Cookie` ist eine Schwesterklasse von `Path` und `Query`. Sie erbt von derselben gemeinsamen `Param`-Elternklasse.

Aber erinnern Sie sich, dass, wenn Sie `Query`, `Path`, `Cookie` und andere von `fastapi` importieren, diese tatsächlich Funktionen sind, welche spezielle Klassen zurückgeben.

/// 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。
