# Réponses supplémentaires dans OpenAPI

/// warning | Attention

Ceci concerne un sujet plutôt avancé.

Si vous débutez avec **FastAPI**, vous n'en aurez peut-être pas besoin.

Vous pouvez déclarer des réponses supplémentaires, avec des codes HTTP, des types de médias, des descriptions, etc.

Ces réponses supplémentaires seront incluses dans le schéma OpenAPI, elles apparaîtront donc également dans la documentation de l'API.

`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.

/// warning

The supporting additional functions `fake_password_hasher` and `fake_save_user` are just to demo a possible flow of the data, but they of course are not providing any real security.
