我想检查上传文件的进度HttpUrlConnection.我怎么能这样做？我曾尝试在写入数据时计算字节数,OutputStream但这是错误的,因为只有在我调用时才会发生真正的上传conn.getInputStream(),因此我需要以某种方式检查inputStream.这是我的代码:

public static void uploadMovie(final HashMap<String, String> dataSource, final OnLoadFinishedListener finishedListener, final ProgressListener progressListener) {
  if (finishedListener != null) {
    new Thread(new Runnable() {
       public void run() {
         try {

              String boundary = getMD5(dataSource.size()+String.valueOf(System.currentTimeMillis()));
              MultipartEntityBuilder multipartEntity = MultipartEntityBuilder.create();
              multipartEntity.setMode(HttpMultipartMode.BROWSER_COMPATIBLE);    
              multipartEntity.setCharset(Charset.forName("UTF-8"));

              for (String key : dataSource.keySet()) {
                 if (key.equals(MoviesFragmentAdd.USERFILE)) {
                    FileBody  userFile = new FileBody(new File(dataSource.get(key)));
                    multipartEntity.addPart(key, userFile);
                    continue;
                 }
                 multipartEntity.addPart(key, new StringBody(dataSource.get(key),ContentType.APPLICATION_JSON));
              }

              HttpEntity entity = multipartEntity.build();
              HttpURLConnection conn = (HttpsURLConnection) new URL(URL_API + …
