Answer 1

나는 "dos.flush()"메소드를 호출해야한다고 생각합니다. 내 코드가 완벽하게 실행되며 postContent는 문자열 버퍼이며 contanins 300KB 문자열입니다.

 if (getPostContent() == null) { 
       httpConnection.setRequestMethod(HttpConnection.GET); 
      } else { 
       String type = "application/x-www-form-urlencoded"; 
       byte[] bytes = postContent.toString().getBytes("UTF-8"); 
       httpConnection.setRequestProperty("Content-Type", type); 
       httpConnection.setRequestProperty("Content-Length", bytes.length + ""); 
       httpConnection.setRequestMethod(HttpConnection.POST); //setupPost method for this conn 
       DataOutputStream dos = new DataOutputStream(httpConnection.openOutputStream()); 
       dos.write(bytes); 
       dos.flush(); 
       dos.close(); 
      }
