为我工作，请尝试不同的网络，如wifi或移动数据
//拨打服务器
HttpResponse response = httpclient.execute（httppost）; HttpEntity r_entity = response.getEntity（）;

在你的android中尝试这个简单的代码，它适用于我，
String url = "";// URL where image has to be uploaded
String fileName = ""; //path of file to be uploaded
HttpClient httpclient = new DefaultHttpClient();
HttpPost httppost = new HttpPost(url);
FileBody fileContent = new FiSystem.out.println("hello");
StringBody comment = new StringBody("Filename: " + fileName);
MultipartEntity reqEntity = new MultipartEntity();
reqEntity.addPart("file", fileContent);
httppost.setEntity(reqEntity);
HttpResponse response = httpclient.execute(httppost);
HttpEntity resEntity = response.getEntity();
希望这可以帮助您解决问题... !!!!!
