E então você também leu como lidar com [CORS com o `CORSMiddleware`](../tutorial/cors.md).

Nesta seção, veremos como usar outros middlewares.

## Adicionando middlewares ASGI { #adding-asgi-middlewares }

  else
    echo "User '$USER' already exists."
  fi
  #clean up credentials files.
  rm -f $MINIO_ACCESSKEY_SECRETKEY_TMP

  # set policy for user
  if [ ! -z $POLICY -a $POLICY != " " ] ; then
      echo "Adding policy '$POLICY' for '$USER'"
      set +e ; # policy already attach errors out, allow it.
      ${MC} admin policy attach myminio $POLICY --user=$USER
      set -e
  else
      echo "User '$USER' has no policy attached."

메인 튜토리얼에서 애플리케이션에 [커스텀 Middleware](../tutorial/middleware.md)를 추가하는 방법을 읽었습니다.

그리고 [`CORSMiddleware`로 CORS 처리하기](../tutorial/cors.md)도 읽었습니다.

이 섹션에서는 다른 middleware들을 사용하는 방법을 살펴보겠습니다.

## ASGI middleware 추가하기 { #adding-asgi-middlewares }

**FastAPI**는 Starlette를 기반으로 하고 <abbr title="Asynchronous Server Gateway Interface - 비동기 서버 게이트웨이 인터페이스">ASGI</abbr> 사양을 구현하므로, 어떤 ASGI middleware든 사용할 수 있습니다.
