	**FastAPI** saberá que pode usar a classe `OAuth2PasswordBearer` (declarada na dependência) para definir o esquema de segurança na OpenAPI porque herda de `fastapi.security.oauth2.OAuth2`, que por sua vez herda de `fastapi.security.base.Securitybase`.

## 현재 유저 주입하기

이제 *경로 작동*에서 `get_current_user`와 동일한 `Depends`를 사용할 수 있습니다.
