## `File` 및 `Form` 매개변수 정의 { #define-file-and-form-parameters }

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

{* ../../docs_src/request_forms_and_files/tutorial001_an_py310.py hl[10:12] *}

파일과 폼 필드는 폼 데이터로 업로드되며, 파일과 폼 필드를 받게 됩니다.

또한 일부 파일은 `bytes`로, 일부 파일은 `UploadFile`로 선언할 수 있습니다.

`File`と`Form`を同時に使うことでファイルとフォームフィールドを定義することができます。

アップロードされたファイルやフォームデータを受信するには、まず[`python-multipart`](https://github.com/Kludex/python-multipart)をインストールします。

[仮想環境](../virtual-environments.md)を作成し、それを有効化してから、例えば次のようにインストールしてください:

```console
$ pip install python-multipart
```

    This is a dependency class to collect the `username` and `password` as form data

    The OAuth2 specification dictates that for a password flow the data should be
    collected using form data (instead of JSON) and that it should have the specific
    fields `username` and `password`.
