大二下学期团队项目（app端web请求与json解析）

今日使用xutils3请求web服务器得到json数据并解析，但是出现了分类查询无法显示图片的问题。

RequestParams params = new RequestParams("http://10.98.16.79:5000/query_tag");
        //params.setMultipart(true);
        params.addBodyParameter("type",str_s[0]);
        params.addBodyParameter("date",str_s[1]);
        params.addBodyParameter("area",str_s[2]);
        params.addBodyParameter("first",str_s[3]);
        params.addBodyParameter("num",str_s[4]);
        //params.addBodyParameter("File",new File(Environment.getExternalStorageDirectory()+"/test_download/YLY.jpg"),null,"YLY.jpg");
        x.http().get(params, new Callback.CacheCallback<String>() {
            List<ListData> list_data_flag=new ArrayList<>();
            @Override
            public boolean onCache(String result) {
                return false;
            }

            @Override
            public void onSuccess(String result) {
                try {
                    JSONObject object=new JSONObject(result);
                    JSONArray array=object.optJSONArray("data");
                    for(int i=0;i<array.length();i++){
