如何使用Android中的Retrofit将多个文件发布到服务器？

Question

我正在尝试使用Retrofit发布多个文件但总是得到 错误

failure  null 

在活动代码中：

MultipartTypedOutput multipartTypedOutput = new MultipartTypedOutput();

multipartTypedOutput.addPart("test_image",
                                new TypedFile("image/png",new File("/sdcard/test.png")));
multipartTypedOutput.addPart("test_audio",
                                new TypedFile("audio/mp3",new File("/sdcard/testaudio.mp3")));



RestAdapter restAdapter = new RestAdapter.Builder()
                 .setEndpoint("http://192.168.10.115/test.php")
                 .setClient(new OkClient(getClient()))
                 .build();

 GetData apiService =restAdapter.create(GetData.class);
 apiService.createPostWithAttachments(multipartTypedOutput, new Callback<Response>() {

                        @Override
                        public void failure(RetrofitError retrofitError) {
                            Log.v("", "failure "+retrofitError.getMessage());

                        }

                        @Override
                        public void success(Response s, Response response) {
                            BufferedReader reader = null;
                            StringBuilder sb = new StringBuilder();
                            try {

                                reader = new BufferedReader(new InputStreamReader(s.getBody().in()));

                                String line;

                                try {
                                    while ((line = reader.readLine()) != null) {
                                        sb.append(line);
                                    }
                                } catch (IOException e) {
                                    e.printStackTrace();
                                }
                            } catch (IOException e) {
                                e.printStackTrace();
                            }

                            String result = sb.toString();
                            Log.v("", "success "+result.toString());
                        }
                    });

OkClient是：

private OkHttpClient getClient() {
        OkHttpClient client = new OkHttpClient();
        client.setConnectTimeout(5, TimeUnit.MINUTES);
        client.setReadTimeout(5, TimeUnit.MINUTES);
        return client;
    }

界面是：

public interface GetData {
    @POST("/")
    void createPostWithAttachments(@Body MultipartTypedOutput attachments,Callback<Response> response);
}

我使用了以下的库：

okhttp-2.2.0.jar
okhttp-urlconnection-2.0.0.jar
okio-1.2.0.jar
retrofit-1.9.0.jar

PHP服务器代码：

$target_dir = "/images/";
    $target_dir = $target_dir . basename($_FILES["test_image"]["name"]);

    $atarget_dir = $target_dir . basename($_FILES["test_audio"]["name"]);
    if(move_uploaded_file($_FILES["test_image"]["tmp_name"], $target_dir))
      {
         $msg = "The file ". basename($result[0]). " has been uploaded.";
         $send_arr['success'] = 1;
         $send_arr['message'] = $msg;
         echo json_encode($send_arr);
      }
      else if(move_uploaded_file($_FILES["test_audio"]["tmp_name"], $atarget_dir))
      {
         $msg = "The file ". basename($result[0]). " has been uploaded.";
         $send_arr['success'] = 1;
         $send_arr['message'] = $msg;
         echo json_encode($send_arr);
      }
    else 
      {
         $msg = "Sorry, there was an error uploading your file.";
         $send_arr['success'] = 0;
         $send_arr['message'] = $msg;
         echo json_encode($send_arr);
      }

提供错误：

当我尝试发布多张图片时，请始终获得回复null或Timeout-exception或failure请告诉我如何使用Retrofit发布多张图片？< / p>
