安卓端同时上传图片和文字，服务器端接收（二）

安卓端同时上传图片和文字，服务器端接收（二）

之前写过一篇（一），代码过于复杂，这次用新的方式实现同样的功能。

Android端主要通过OkHttp3实现上传

    private static final MediaType MEDIA_TYPE_PNG = MediaType.parse("image/png");  private final OkHttpClient client = new OkHttpClient();  public String upload(String imageType,String userPhone,File file) throws NetworkException{  RequestBody fileBody = ate(MediaType.parse("image/png"), file);  RequestBody requestBody = new MultipartBody.Builder()  .setType(MultipartBody.FORM)  .addFormDataPart("file", "head_image", fileBody)  .addFormDataPart("name", "name")  .addFormDataPart("email", "email")  .build();  Request request = new Request.Builder()  .url("xxxxx")  .post(requestBody)  .build();  Response response;  try {  response = wCall(request).execute();  String json = response.body().string();System.out.println(json);if (response.isSuccessful()) {System.out.println("上传成功");} else {System.out.println("上传失败");}} catch (IOException e) {  e.printStackTrace();}return null;  }  

服务器端代码:

	/*** 移动端上传数据和图片* @param request* @return*/@PostMapping(value = "upload")@ResponseBodypublic String mobileUpload(HttpServletRequest request){JSONObject jsonObject = new JSONObject();//创建一个通用的多部分解析器CommonsMultipartResolver multipartResolver = new Session().getServletContext());Upload upload = new Upload();try{String name = Parameter("name");String email = Parameter("email");logger.info(name);logger.info(email);}catch (Exception e){e.printStackTrace();String();}try{//上传图片部分
//            List<String> imgs = new ArrayList<String>();if(multipartResolver.isMultipart(request)) {//转换成多部分requestMultipartHttpServletRequest multiRequest = (MultipartHttpServletRequest) request;Map<String, MultipartFile> fileMap = FileMap();Iterator<String> fileNameIterator = fileMap.keySet().iterator();//上传路径File filedir = new File(UploadFileUtil.MOBILE_IMAGE_DIR);if (!ists() && !filedir.isDirectory()){filedir.mkdirs();}//获取到图片且必须一张if (fileNameIterator.hasNext()) {MultipartFile file = (());if (file.isEmpty() || Size() == 0) {}String [] strings = ContentType().split("/");String type = strings[1];logger.info("图片类型:" + type);//重命名上传后的文件名Date date = new Date();SimpleDateFormat sdf = new SimpleDateFormat("yyyyMMddHHmmss");String fileName = sdf.format(date) + "." + type;logger.info("文件名称为:"+fileName);//定义上传路径File localFile = new File(UploadFileUtil.MOBILE_IMAGE_DIR + fileName);ansferTo(localFile);System.out.println("上传路径为:" &#Path());//设置图片路径upload.Path());} else {//没有上传图片的话，则抛出异常throw new Exception("未上传图片");}        }} catch (Exception e){jsonObject.put("result",false);jsonObject.put("msg",e.getMessage());String();}jsonObject.put("result",true);jsonObject.put("msg","success");String();}
