쿠키 매개변수를 `Query`와 `Path` 매개변수들과 같은 방식으로 정의할 수 있습니다.

## `Cookie` 임포트

먼저 `Cookie`를 임포트합니다:

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

## `Cookie` 매개변수 선언

그런 다음, `Path`와 `Query`처럼 동일한 구조를 사용하는 쿠키 매개변수를 선언합니다.

첫 번째 값은 기본값이며, 추가 검증이나 어노테이션 매개변수 모두 전달할 수 있습니다:

{* ../../docs_src/cookie_params/tutorial001_an_py310.py hl[9] *}

/// note | 기술 세부사항

# Header-параметри

Ви можете визначати параметри заголовків, так само як визначаєте `Query`, `Path` і `Cookie` параметри.

## Імпорт `Header`

Спочатку імпортуйте `Header`:

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

## Оголошення параметрів `Header`

Потім оголосіть параметри заголовків, використовуючи ту ж структуру, що й для `Path`, `Query` та `Cookie`.
