It has a `GET` operation that could return an error.

It has a `POST` operation that could return several errors.

Both *path operations* require an `X-Token` header.

### Extended testing file { #extended-testing-file }

You could then update `test_main.py` with the extended tests:

	debugGoCollectorPath collectorPath = "/debug/go"

	clusterHealthCollectorPath       collectorPath = "/cluster/health"

	clusterUsageBucketsCollectorPath collectorPath = "/cluster/usage/buckets"
	clusterErasureSetCollectorPath   collectorPath = "/cluster/erasure-set"

        assertTrue(length >= 0);
    }

이 경우, 프론트엔드가 제대로 동작하기 위해 `http://localhost:8080`을 목록에 포함해야 합니다.

## 와일드카드

모든 출처를 허용하기 위해 목록을 `"*"` ("와일드카드")로 선언하는 것도 가능합니다.

하지만 이것은 특정한 유형의 통신만을 허용하며, 쿠키 및 액세스 토큰과 사용되는 인증 헤더(Authoriztion header) 등이 포함된 경우와 같이 자격 증명(credentials)이 포함된 통신은 허용되지 않습니다.

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.
