## 사용자 정의 `PNGStreamingResponse` { #a-custom-pngstreamingresponse }

위 예시에서는 바이트 데이터를 스트리밍했지만, 응답에 `Content-Type` 헤더가 없어 클라이언트는 어떤 유형의 데이터를 받는지 알 수 없습니다.

스트리밍하는 데이터 유형에 맞춰 `Content-Type` 헤더를 설정하는 `StreamingResponse`의 하위 클래스를 직접 만들 수 있습니다.

예를 들어 `media_type` 속성을 사용해 `Content-Type` 헤더를 `image/png`로 설정하는 `PNGStreamingResponse`를 만들 수 있습니다:

{* ../../docs_src/stream_data/tutorial002_py310.py ln[6,19:20] hl[20] *}

Bu aslında standart Python'dır; buna "type alias" denir ve **FastAPI**'ye özel bir şey değildir.

Ama **FastAPI**, `Annotated` dahil Python standartları üzerine kurulu olduğu için bu tekniği kodunuzda kullanabilirsiniz. 😎
