`OAuth2PasswordRequestForm`은 다음을 사용하여 폼 본문을 선언하는 클래스 의존성입니다:

* `username`.
* `password`.
* `scope`는 선택적인 필드로 공백으로 구분된 문자열로 구성된 큰 문자열입니다.
* `grant_type`(선택적으로 사용).

!!! 팁
    OAuth2 사양은 실제로 `password`라는 고정 값이 있는 `grant_type` 필드를 *요구*하지만 `OAuth2PasswordRequestForm`은 이를 강요하지 않습니다.

    사용해야 한다면 `OAuth2PasswordRequestForm` 대신 `OAuth2PasswordRequestFormStrict`를 사용하면 됩니다.

* Dem `username`.
* Dem `password`.
* Einem optionalen `scope`-Feld als langem String, bestehend aus durch Leerzeichen getrennten Strings.
* Einem optionalen `grant_type` („Art der Anmeldung“).

!!! tip "Tipp"
    Die OAuth2-Spezifikation *erfordert* tatsächlich ein Feld `grant_type` mit dem festen Wert `password`, aber `OAuth2PasswordRequestForm` erzwingt dies nicht.

* The `username`.
* The `password`.
* An optional `scope` field as a big string, composed of strings separated by spaces.
* An optional `grant_type`.

!!! tip
    The OAuth2 spec actually *requires* a field `grant_type` with a fixed value of `password`, but `OAuth2PasswordRequestForm` doesn't enforce it.
