## `File` 및 `Form` 매개변수 정의

`Body` 및 `Query`와 동일한 방식으로 파일과 폼의 매개변수를 생성합니다:

{* ../../docs_src/request_forms_and_files/tutorial001.py hl[8] *}

파일과 폼 필드는 폼 데이터 형식으로 업로드되어 파일과 폼 필드로 전달됩니다.

어떤 파일들은 `bytes`로, 또 어떤 파일들은 `UploadFile`로 선언할 수 있습니다.

`File` es una clase que hereda directamente de `Form`.

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

///

/// tip | Consejo

Para declarar cuerpos de File, necesitas usar `File`, porque de otra manera los parámetros serían interpretados como parámetros query o parámetros de cuerpo (JSON).

Los archivos se subirán como "form data".
