在Activity中调用的方法

                File file = new File(PhotoFileName);                 String fileKey = "file"; //这个是关键，需要注意 在我的上一篇文章中有MVC上传文件的方法，需要和<input name="file">中name相同                UploadUtil1 uploadUtil = UploadUtil1.getInstance();                Map<String, String> params = new HashMap<String, String>();                params.put("barcode", "11111"); //这里是另外一个<input name="barcode">                uploadUtil.uploadFile(  file,fileKey, UploadImageURL,params);                 PhotoResult.setImageBitmap(null);
