/// info

`File` is a class that inherits directly from `Form`.

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

///

/// tip

To declare File bodies, you need to use `File`, because otherwise the parameters would be interpreted as query parameters or body (JSON) parameters.

///

The files will be uploaded as "form data".

## `File` und `Form`-Parameter definieren

Erstellen Sie Datei- und Formularparameter, so wie Sie es auch mit `Body` und `Query` machen würden:

{* ../../docs_src/request_forms_and_files/tutorial001_an_py39.py hl[10:12] *}

Die Datei- und Formularfelder werden als Formulardaten hochgeladen, und Sie erhalten diese Dateien und Formularfelder.

## `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.

## Define `File` and `Form` parameters { #define-file-and-form-parameters }

Create file and form parameters the same way you would for `Body` or `Query`:

{* ../../docs_src/request_forms_and_files/tutorial001_an_py39.py hl[10:12] *}

The files and form fields will be uploaded as form data and you will receive the files and form fields.
