415 android에서 파일을 업로드하는 중 오류가 발생했습니다.

Question

웹 서버에 mp3 파일을 업로드하고 문자열로 응답해야하지만 HTTP 응답이 415 오류가납니다. 콘텐츠 유형이 'multipart/form-data; boundary = * '이 (가) 예상되는 유형이 아니 었습니다'application/soap + xml; charset = utf-8 ': 415, 여기 내 코드가 있습니다. 왜 서버가이 형식을 거부합니까?

public static int upLoad2Server(String sourceFileUri) {

Answer 1

코드는 다음과 같습니다

conn.setRequestProperty("Content-Type", "multipart/form-data;boundary=" + boundary); 

와 오류는이 될 Content-Type를 기대하고 있다고 머물고있다 :

application/soap+xml; charset=utf-8 

나는 당신이 설정하는 이유 - 검사 재 추천 콘텐츠 유형이 서버가 받아 들일 수있는 다른 것까지 허용합니다.
