Zum Beispiel stellt eine der Möglichkeiten, die OAuth2-Spezifikation zu verwenden (genannt „password flow“), die Bedingung, einen `username` und ein `password` als Formularfelder zu senden.

Die <abbr title="Specification – Spezifikation">Spec</abbr> erfordert, dass die Felder exakt `username` und `password` genannt werden und als Formularfelder, nicht JSON, gesendet werden.

예를 들어, OAuth2 사양을 사용할 수 있는 방법 중 하나("패스워드 플로우"라고 함)로 `username`과 `password`를 폼 필드로 보내야 합니다.

<abbr title="specification">사양</abbr>에서는 필드 이름이 `username` 및 `password`로 정확하게 명명되어야 하고, JSON이 아닌 폼 필드로 전송해야 합니다.

`Form`을 사용하면 유효성 검사, 예제, 별칭(예: `username` 대신 `user-name`) 등을 포함하여 `Body`(및 `Query`, `Path`, `Cookie`)와 동일한 구성을 선언할 수 있습니다.

/// info | 정보

Но вы не ограничены использованием какой-то конкретной модели данных, класса или типа.

Хотите, чтобы в модели были `id` и `email`, но не было `username`? Пожалуйста. Можно использовать те же инструменты.

Хотите просто `str`? Или просто `dict`? Или напрямую экземпляр класса модели базы данных? Всё работает одинаково.
