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 :
