应用自带JSONObject解析JSON数据

使用自带JSONObject解析JSON数据

import org.json.JSONArray;import org.json.JSONException;import org.json.JSONObject;//获取解析的串，如下json串public static String getJsonString(String urlPath) throws Exception {  StringBuffer sb = new StringBuffer();  try {URL url = new URL(urlPath);          HttpURLConnection connection = (HttpURLConnection) url.openConnection();          connection.setConnectTimeout(50000);        connection.connect();          InputStream inputStream = connection.getInputStream();          //对应的字符编码转换          Reader reader = new InputStreamReader(inputStream, "UTF-8");          BufferedReader bufferedReader = new BufferedReader(reader);          String str = null;          while ((str = bufferedReader.readLine()) != null) {              sb.append(str);          }          reader.close();          connection.disconnect();  } catch (Exception e) {// TODO: handle exceptione.printStackTrace();System.out.println("连接超时。。。");return "timeout";}               return sb.toString();      }  

json字串 :

{"response":"ok","result":{"userList":[{"name":"9S7B_music_user","id":162,"type":2,"date":1375780379000,"pwd":"e10adc3949ba59abbe56e057f20f883e","cyCount":1,"ctCount":1,"myCount":1,"cgCount":21,"gold":11},{"name":"fred26","id":129,"type":2,"date":1375781355000,"pwd":"e10adc3949ba59abbe56e057f20f883e","cyCount":3,"ctCount":1,"myCount":1,"cgCount":7,"gold":3},{"name":"2VPL_music_user","id":170,"type":2,"date":1376032147000,"pwd":"e10adc3949ba59abbe56e057f20f883e","cyCount":1,"ctCount":1,"myCount":1,"cgCount":6,"gold":1},{"name":"T8D8_music_user","id":167,"type":2,"date":1375844980000,"pwd":"e10adc3949ba59abbe56e057f20f883e","cyCount":1,"ctCount":1,"myCount":1,"cgCount":6,"gold":15},{"name":"VFWR_music_user","id":159,"type":2,"date":1375777245000,"pwd":"e10adc3949ba59abbe56e057f20f883e","cyCount":1,"ctCount":1,"myCount":1,"cgCount":5,"gold":5},{"name":"dadaf","id":171,"type":2,"date":1376034139000,"pwd":"e10adc3949ba59abbe56e057f20f883e","cyCount":1,"ctCount":1,"myCount":1,"cgCount":4,"gold":2},{"name":"WGOL_music_user","id":166,"type":2,"date":1375843886000,"pwd":"e10adc3949ba59abbe56e057f20f883e","cyCount":1,"ctCount":1,"myCount":1,"cgCount":4,"gold":2}}]}}
