## どう見えるか

まずはこのコードを使って、どう動くか観察します。その後で、何が起こっているのか理解しましょう。

## `main.py`を作成

`main.py`に、下記の例をコピーします:

{* ../../docs_src/security/tutorial001.py *}

## 実行

/// info | 情報

まず<a href="https://github.com/Kludex/python-multipart" class="external-link" target="_blank">`python-multipart`</a>をインストールします。

例えば、`pip install python-multipart`。

これは、**OAuth2**が `ユーザー名` や `パスワード` を送信するために、「フォームデータ」を使うからです。
