    * したがって、APIで認証するため、HTTPヘッダー`Authorization`に`Bearer`の文字列とトークンを加えた値を送信します。
    * トークンに`foobar`が含まれている場合、`Authorization`ヘッダーの内容は次のようになります: `Bearer foobar`。

## **FastAPI**の`OAuth2PasswordBearer`

**FastAPI**は、これらのセキュリティ機能を実装するために、抽象度の異なる複数のツールを提供しています。

この例では、**Bearer**トークンを使用して**OAuth2**を**パスワード**フローで使用します。これには`OAuth2PasswordBearer`クラスを使用します。

/// info | "情報"

「bearer」トークンが、唯一の選択肢ではありません。

しかし、私たちのユースケースには最適です。
