Retrofit2：如何在android中使用JSONObject上传图像

Question

我正在尝试用相机运行时拍摄的一张图像发布JSONObject。如何在android中使用改造发布图像。这是我的界面

 @Multipart
@POST("/upload")
Call<Response> getDetails(@Part("empsno") String  empsno,
                                @Part("time")String deliveryTime,
                                @Part("uploadFile") MultipartBody.Part part,
                                @Part("remarks")String remarks,
                                @Part("receiver")String receivedBy,
                                @Part("Address")String ipAddress
                                );

我用来上传图片和其他细节的代码

 JSONObject oJSONObject = new JSONObject();
        oJSONObject.put("empsno", strEmpsno);
        oJSONObject.put("time", strtime);
        oJSONObject.put("remarks", strRemarks);
        oJSONObject.put("receiver", strReceiver);
        oJSONObject.put("Address", straddress);
        oJSONObject.put("uploadFile", imageFolderPath + "/" + imageName);

RequestBody requestFile = RequestBody.create(MediaType.parse("multipart/form-data"), file);
MultipartBody.Part body = MultipartBody.Part.createFormData("uploadFile", file.getName(), requestFile);

xInterface interface = retrofit.create(xInterface.class);
Call<Response> podResponsecall = interface.getDetails(strEmpsno, strtime,
                body, strRemarks, strReceiver, straddress);


  podResponsecall.enqueue(new Callback<Response>() {
            @Override
            public void onResponse(Response<Response> response) {
                String val = response.body() + "";
                Log.e(TAG, "onResponse: " + val);
            }

            @Override
            public void onFailure(Throwable t) {
                Log.e(TAG, "onFailure: " + t.getLocalizedMessage());
            }
        });

输出-onFailure：JSON必须以数组或对象开头。

我不知道这是对还是错。请帮助我发布一些图片以及使用Reformat2 beta 3的其他详细信息。

代替

@Multipart
@POST("/upload")
Call<ResponseBody> getDetails(@Part("empsno") RequestBody empsno,
                                @Part("time")RequestBody deliveryTime,
                                @Part("uploadFile") MultipartBody.Part part,
                                @Part("remarks")RequestBody remarks,
                                @Part("receiver")RequestBody receivedBy,
                                @Part("Address")RequestBody ipAddress
                                );

而且在

Call<ResponseBody> podResponsecall = interface.getDetails(strEmpsno, strtime,
                body, strRemarks, strReceiver, straddress);

服务类别：

    @Multipart
    @POST("upload")
    Call<Void> upload(@Part("model") RequestBody model,  @Part MultipartBody.Part file); 

改装2部分：

    Gson gson = new GsonBuilder().setLenient().create();
    RequestBody modelBody = RequestBody.create(MediaType.parse("application/json"), gson.toJson(modelPojo));
    RequestBody reqFileBody = RequestBody.create(MediaType.parse("multipart/form-data"), file);
    MultipartBody.Part mPart1 = MultipartBody.Part.createFormData("file","name",reqFileBody);

JavaSpring：

   @PostMapping(value="/upload" ,consumes = {"multipart/form-data","application/json"})
    public ResponseEntity<Object> uploadImagebyEmail(@RequestPart("model") Object model,@RequestPart("file") MultipartFile uploadfile  ) throws IOException {
    return //codes here...   
    }
