그런 다음 경로 처리 함수에서 `response_class=PNGStreamingResponse`로 이 새 클래스를 사용할 수 있습니다:

### 파일 시뮬레이션 { #simulate-a-file }

이 예시에서는 `io.BytesIO`로 파일을 시뮬레이션합니다. 이는 메모리에서만 존재하지만 파일과 동일한 인터페이스를 제공하는 파일 유사 객체입니다.

예를 들어 실제 파일처럼 내용을 소비하기 위해 순회(iterate)할 수 있습니다.

type bufReader struct {
	name string
	fn   func(*Reader) string
}

var bufreaders = []bufReader{
	{"1", func(b *Reader) string { return reads(b, 1) }},
	{"2", func(b *Reader) string { return reads(b, 2) }},
	{"3", func(b *Reader) string { return reads(b, 3) }},
	{"4", func(b *Reader) string { return reads(b, 4) }},
	{"5", func(b *Reader) string { return reads(b, 5) }},
	{"7", func(b *Reader) string { return reads(b, 7) }},
