1.获取服务器接口数据方法：记得导入httpclient包

 public static String getdata(String url, List params) {
         String tag = "";
         HttpClient httpClient = new DefaultHttpClient();
         HttpPost post = new HttpPost(url);


         try {
             UrlEncodedFormEntity entity = new UrlEncodedFormEntity(params,"utf-8");
             post.setEntity(entity);
             try {
                 HttpResponse httpResponse = httpClient.execute(post);
                 tag = "get string false";
                 if (httpResponse.getStatusLine().getStatusCode() == 200) {
                     HttpEntity entity2 = httpResponse.getEntity();
                     tag=EntityUtils.toString(entity2);
                     //tag = Decodtool.decodeUnicode(URLDecoder.decode(EntityUtils.toString(entity2, "uft-8"), "utf-8"));
                 }
             } catch (ClientProtocolException e) {
                 e.printStackTrace();
             } catch (IOException e) {
                 e.printStackTrace();
             }
         } catch (UnsupportedEncodingException e) {
             e.printStackTrace();
         }
         return tag;

     }

2.通过Gson解析：记得导入Gson包

 public static void main(String[] args) {

         String data = getdata();
         System.out.println(parase(data).toString());
     }

     private static String getdata() {
         String url = "http://192.168.2.171:9898/Service_Resource.ashx";
         ArrayList params = new ArrayList();
         params.add(new BasicNameValuePair("method", "GetAll"));
         return NetworkUtil.getdata(url, params);
     }

     private static ArrayList parase(String data) {
         Gson gson = new Gson();
         JSONObject jsonObject = JSONObject.fromObject(data);
         String datapart = jsonObject.getString("data");
         Type type = new TypeToken>() {}.getType();
         ArrayList resourcebeans = gson.fromJson(datapart, type);
         return resourcebeans;
     }
