    * Поэтому для аутентификации в нашем API он посылает заголовок `Authorization` со значением `Bearer` плюс сам токен.
    * Если токен содержит `foobar`, то содержание заголовка `Authorization` будет таким: `Bearer foobar`.

## Класс `OAuth2PasswordBearer` в **FastAPI**

**FastAPI** предоставляет несколько средств на разных уровнях абстракции для реализации этих функций безопасности.

   * the sequence will be returned as a string with no changes to the content.
   *
   * <p>Examples:
   *
   * {@snippet :
   * Ascii.truncate("foobar", 7, "..."); // returns "foobar"
   * Ascii.truncate("foobar", 5, "..."); // returns "fo..."
   * }
   *
   * <p><b>Note:</b> This method <i>may</i> work with certain non-ASCII text but is not safe for use

* フロントエンドはAPIからさらにデータを取得する必要があります。
    * しかし、特定のエンドポイントの認証が必要です。
    * 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`。
