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 exception
			e.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}}]}}
