# Middleware

Sie können Middleware zu **FastAPI**-Anwendungen hinzufügen.

Eine „Middleware“ ist eine Funktion, die mit jedem **Request** arbeitet, bevor er von einer bestimmten *Pfadoperation* verarbeitet wird. Und auch mit jeder **Response**, bevor sie zurückgegeben wird.

* Sie nimmt jeden **Request** entgegen, der an Ihre Anwendung gesendet wird.
* Sie kann dann etwas mit diesem **Request** tun oder beliebigen Code ausführen.

따라서 모든 작업을 의도한대로 실행하기 위해, 허용되는 출처를 명시적으로 지정하는 것이 좋습니다.

## `CORSMiddleware` 사용

`CORSMiddleware` 을 사용하여 **FastAPI** 응용 프로그램의 교차 출처 리소스 공유 환경을 설정할 수 있습니다.

* `CORSMiddleware` 임포트.
* 허용되는 출처(문자열 형식)의 리스트 생성.
* FastAPI 응용 프로그램에 "미들웨어(middleware)"로 추가.

백엔드에서 다음의 사항을 허용할지에 대해 설정할 수도 있습니다:

* 자격증명 (인증 헤더, 쿠키 등).
* 특정한 HTTP 메소드(`POST`, `PUT`) 또는 와일드카드 `"*"` 를 사용한 모든 HTTP 메소드.
