"DocumentListEntry.updateMedia()"메서드를 사용하는 동안 GData API에 문제가 발생했습니다.

Question

GData API에서 DocumentListEntry의 updateMedia (boolean) 메소드를 사용하고 있습니다. 이 명령이 작동하는 경우가 있지만 대부분 예외가 발생합니다.

코드는 (documentList는 DocumentListEntry 객체 인) :

public void flush() throws IOException { 
    try { 
     if(((ByteArrayOutputStream)os).size()>0){ 
      documentList.setMediaSource(
        new MediaByteArraySource(((ByteArrayOutputStream)os).toByteArray(), mimeType)); 
      documentList.updateMedia(true); 
      ((ByteArrayOutputStream)os).reset(); 
     } 
    } catch (ServiceException ex) { 
     throw new IOException(ex); 
    } 
} 

명령 "(참) documentList.updateMedia;" 이 예외가 throw됩니다.

누군가가 도와 줄 수 있습니까?

Answer 1

"documentList.setETag (String)"명령이 누락되었음을 발견했습니다. 그런 다음 '*'문자를 설정하고 작동합니다!
