使用httputils上传图片到服务器

 //创建httpUtils对象
 HttpUtils mRegHttpUtils = new HttpUtils();
 //图片路径
 String path = "/sdcard/Download/zxing.jpg";
 //param
 RequestParams params = new RequestParams();
 //将图片封装为file
 params.addBodyParameter("f_img",new File(path));
 //以post方式发送到urlstring服务器
 mRegHttpUtils.send(HttpMethod.POST,
                         urlstring, params,
                         new RequestCallBack<String>() {

                             @Override
                             public void onFailure(HttpException arg0,
                                     String arg1) {
                                 // TODO Auto-generated method stub
                                 Log.i("tag", "failed" + arg0.toString());
                             }

                             @Override
                             public void onStart() {
                                 // TODO Auto-generated method stub
                                 super.onStart();
                             }

                             @Override
                             public void onSuccess(ResponseInfo<String> arg0) {
                                 // TODO Auto-generated method stub
                                  //返回结果       
                             Log.i("tag","success"+arg0.result);

                             }
                         });
