## `Form` 임포트하기

`fastapi`에서 `Form`을 임포트합니다:

{* ../../docs_src/request_forms/tutorial001_an_py39.py hl[3] *}

## `Form` 매개변수 정의하기

`Body` 또는 `Query`와 동일한 방식으로 폼 매개변수를 만듭니다:

{* ../../docs_src/request_forms/tutorial001_an_py39.py hl[9] *}

예를 들어, OAuth2 사양을 사용할 수 있는 방법 중 하나("패스워드 플로우"라고 함)로 `username`과 `password`를 폼 필드로 보내야 합니다.
