`FastAPI` 애플리케이션의 `lifespan` 매개변수는 **비동기 컨텍스트 매니저**를 받기 때문에, 새로운 `lifespan` 비동기 컨텍스트 매니저를 FastAPI에 전달할 수 있습니다.

## 대체 이벤트 (사용 중단)

/// warning | 경고

*시작*과 *종료*를 처리하는 권장 방법은 위에서 설명한 대로 `FastAPI` 애플리케이션의 `lifespan` 매개변수를 사용하는 것입니다. `lifespan` 매개변수를 제공하면 `startup`과 `shutdown` 이벤트 핸들러는 더 이상 호출되지 않습니다. `lifespan`을 사용할지, 모든 이벤트를 사용할지 선택해야 하며 둘 다 사용할 수는 없습니다.

В этом разделе вы увидите, как управлять аутентификацией и авторизацией с теми же OAuth2 scopes в вашем приложении на **FastAPI**.

/// warning | Предупреждение

Это более-менее продвинутый раздел. Если вы только начинаете, можете пропустить его.

Вам не обязательно нужны OAuth2 scopes — аутентификацию и авторизацию можно реализовать любым нужным вам способом.
