## Unterabhängigkeiten mit `yield`.

Sie können Unterabhängigkeiten und „Bäume“ von Unterabhängigkeiten beliebiger Größe und Form haben, und einige oder alle davon können `yield` verwenden.

**FastAPI** stellt sicher, dass der „Exit-Code“ in jeder Abhängigkeit mit `yield` in der richtigen Reihenfolge ausgeführt wird.

`OAuth2PasswordRequestForm`은 `OAuth2PasswordBearer`와 같이 **FastAPI**에 대한 특수 클래스가 아닙니다.

`OAuth2PasswordBearer`는 **FastAPI**가 보안 체계임을 알도록 합니다. 그래서 OpenAPI에 그렇게 추가됩니다.

그러나 `OAuth2PasswordRequestForm`은 직접 작성하거나 `Form` 매개변수를 직접 선언할 수 있는 클래스 의존성일 뿐입니다.

그러나 일반적인 사용 사례이므로 더 쉽게 하기 위해 **FastAPI**에서 직접 제공합니다.
