Question

我正在尝试通过android将其工作文件在邮递员上上传到我的nodejs服务器上的图像，但在android中失败。我正在使用okhttp和改造库。我已经搜索了很多关于堆栈溢出的解决方案和一些博客，但是在我的情况下它们都没有起作用。Retrofit调用什么都不会返回。

我的节点js上传代码：

const express = require('express');
const bodyParser = require('body-parser');
const authenticate = require('../authenticate');
const multer = require('multer');
const cors = require('./cors');
const crypto = require("crypto");



const storage = multer.diskStorage({
    destination:(req,file,cb) => {
        cb(null,'/mnt/images');
    },

    filename : (req,file,cb) => {
        cb(null,/*file.originalname*/crypto.randomBytes(16).toString("hex"))
    }
});

const imageFileFilter = (req,file,cb) => {

    if(!file.originalname.match(/\.(jpg|jpeg|png)$/)){
        return cb(new Error('You can upload image files!'),false);
    }else{
        cb(null,true);
    }



};

const upload = multer({storage : storage,fileFilter:imageFileFilter});


const uploadRouter = express.Router();

uploadRouter.use(bodyParser.json());

uploadRouter.route('/')
.options(cors.corsWithOptions, (req, res) => { res.sendStatus(200) })
.get(cors.cors,authenticate.verifyUser, authenticate.verifyAdmin, (req, res, next) => {
    res.statusCode = 403;
    res.end('PUT operation not supported on /imageUpload');
})
.get(cors.corsWithOptions,authenticate.verifyUser,authenticate.verifyUser, authenticate.verifyAdmin, (req, res, next) => {
    res.statusCode = 403;
    res.end('GET operation not supported on /imageUpload');
})
.delete(cors.corsWithOptions,authenticate.verifyUser,authenticate.verifyUser, authenticate.verifyAdmin, (req, res, next) => {
    res.statusCode = 403;
    res.end('DELTE operation not supported on /imageUpload');
})
.post(cors.cors,authenticate.verifyUser,
    upload.single('imageFile'), (req, res) => {
        res.statusCode = 200;
        res.setHeader('Content-Type','application/json');
        res.json(req.file);   
});


module.exports = uploadRouter;

我想按键上传图像，并按值上传图像，如带帖子的图像所示。在邮递员上工作正常。

我的Android代码：上传功能：

private void upload(){

        ServiceGenerator serviceGenerator = new ServiceGenerator();
        ApiInterface apiInterface = serviceGenerator.createImageUploadService(ApiInterface.class,getContext());
        File file = new File(filePath.getPath());
        RequestBody reqFile = RequestBody.create(MediaType.parse("image/*"), file);
        MultipartBody.Part body = MultipartBody.Part.createFormData("imageFile", file.getName(), reqFile);
        RequestBody name = RequestBody.create(MediaType.parse("text/plain"), "imageFile");
        Call<ResponseBody> call = apiInterface.postImage("bearer "+sharedPreferences.getString(Constants.JWT,""),body,name);
        call.enqueue(new Callback<ResponseBody>() {
            @Override
            public void onResponse(Call<ResponseBody> call, Response<ResponseBody> response) {
                Log.i("RESPONSE","1");
            }

            @Override
            public void onFailure(Call<ResponseBody> call, Throwable t) {
                Log.i("RESPONSE","0");
                Log.i("RESPONSE",t.getCause().toString());

            }
        });

    }

服务生成器CreateUploadService函数：

public <T> T createImageUploadService(Class<T> serviceClass, final Context context){

        HttpLoggingInterceptor interceptor = new HttpLoggingInterceptor();

        interceptor.setLevel(HttpLoggingInterceptor.Level.BODY);

        OkHttpClient client = new OkHttpClient.Builder().addInterceptor(interceptor).build();


        if(retrofit == null){
            retrofit = new Retrofit.Builder()
                    .client(client)
                    .baseUrl(Constants.BASE_API_URL)
                    /*.addConverterFactory(GsonConverterFactory.create(gson))*/
                    .build();
        }
        return retrofit.create(serviceClass);
    }

API接口：

@Multipart
    @POST("imageUpload")
    Call<ResponseBody> postImage(@Header("Authorization") String authHeader,@Part MultipartBody.Part image, @Part("name") RequestBody name);

在节点js服务器android上上传图像（多部分数据）
