`Cookie` ist eine „Schwester“-Klasse von `Path` und `Query`. Sie erbt auch von derselben gemeinsamen `Param`-Klasse.

Aber denken Sie daran, dass, wenn Sie `Query`, `Path`, `Cookie` und andere von `fastapi` importieren, diese tatsächlich Funktionen sind, die spezielle Klassen zurückgeben.

///

/// info | Info

Um Cookies zu deklarieren, müssen Sie `Cookie` verwenden, da die Parameter sonst als Query-Parameter interpretiert würden.

`Cookie` es una clase "hermana" de `Path` y `Query`. También hereda de la misma clase común `Param`.

Pero recuerda que cuando importas `Query`, `Path`, `Cookie` y otros desde `fastapi`, en realidad son funciones que devuelven clases especiales.

///

/// info | Información

Para declarar cookies, necesitas usar `Cookie`, porque de lo contrario los parámetros serían interpretados como parámetros de query.

`Cookie` is a "sister" class of `Path` and `Query`. It also inherits from the same common `Param` class.

But remember that when you import `Query`, `Path`, `Cookie` and others from `fastapi`, those are actually functions that return special classes.

To declare cookies, you need to use `Cookie`, because otherwise the parameters would be interpreted as query parameters.

Ви можете визначити параметри Cookie таким же чином, як визначаються параметри `Query` і `Path`.

## Імпорт `Cookie`

Спочатку імпортуйте `Cookie`:

{* ../../docs_src/cookie_params/tutorial001_an_py310.py hl[3] *}

## Визначення параметрів `Cookie`

Потім визначте параметри cookie, використовуючи таку ж конструкцію як для `Path` і `Query`.
