Question

我正在尝试从我的Android应用程序向服务器发送一个mp3文件。我使用这种方法android async http来发送mp3文件。

这是我的代码。

            try {
                params1.put("file", new ByteArrayInputStream(MeetingFragment.mediafile));
            } catch (FileNotFoundException e1) {
                // TODO Auto-generated catch block
                e1.printStackTrace();
            }

            AsyncClientHandler.post("events/Uploadrecording/5", params1,
                    new AsyncHttpResponseHandler() {

                        @Override
                        public void onFailure(int statusCode,
                                Throwable error, String content) {
                            // TODO Auto-generated method stub
                            super.onFailure(statusCode, error, content);
                            Log.i("filename",myFile.toString());
                            Toast.makeText(_context, "failiure push"+ProjectEventFragment.event.eve_id, Toast.LENGTH_SHORT).show();
                        }

                        @SuppressWarnings("deprecation")
                        @Override
                        public void onSuccess(int statusCode,
                                Header[] headers, String content) {
                            // TODO Auto-generated method stub
                            super.onSuccess(statusCode, headers, content);
                            Toast.makeText(_context, "success push"+ProjectEventFragment.event.eve_id, Toast.LENGTH_SHORT).show();
                            Log.i("Successpush",content.toString());
                        }                   

                    });

我已经给出了正确的URL，我也获得了该文件的价值。但这是成功的一部分。任何人都可以帮我解决这个问题吗？如果您知道任何其他方式，请建议我。提前谢谢。

public static byte[] mediafile;
public static String record_file=null
 myAudioRecorder = new MediaRecorder();
      myAudioRecorder.setAudioSource(MediaRecorder.AudioSource.MIC);
      myAudioRecorder.setOutputFormat(MediaRecorder.OutputFormat.THREE_GPP);
      myAudioRecorder.setAudioEncoder(MediaRecorder.OutputFormat.AMR_NB);
      myAudioRecorder.setOutputFile(record_file);
      mediafile = record_file.getBytes();

    }

    /**
     * After completing background task Dismiss the progress dialog

    protected void onPostExecute(String file_url) {
    }

}

php code（fileupload.php）

 <?php
  $uploads_dir = './';
  $tmp_name = $_FILES['bill']['tmp_name'];
  $pic_name = $_FILES['bill']['name'];

  if (move_uploaded_file($tmp_name, $uploads_dir.$pic_name )) {
  }           
 ?>
