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.

    // propagates cancellation if the callable has not yet been invoked.

Instead of adding suggestions to the translation PR, make the suggestions to the LLM prompt file for that language, in a new PR. For example, for Spanish, the LLM prompt file is at: [`docs/es/llm-prompt.md`](https://github.com/fastapi/fastapi/blob/master/docs/es/llm-prompt.md).

/// tip

That is not the same as declaring default values like would be with:

```Python
    first_name="john", last_name="doe"
```

It's a different thing.

We are using colons (`:`), not equals (`=`).

And adding type hints normally doesn't change what happens from what would happen without them.

But now, imagine you are again in the middle of creating that function, but with type hints.
