认识达内从这里开始

昆明达内培训的小编这一期给大家讲json两层解析。

1 public class Demo {

3    public static void main(String[] args) {

4        try {

5            //创建连接                             服务器的连接地址

6            URL url = new URL(

7                    "#/v1/mobile/address/query?phone=13026610069&key=1b2e046d45634");

8            try {

9                //创建输入流

10                BufferedReader br = new BufferedReader(new InputStreamReader(url.openStream()));

11                //创建一个StringBuffer对象

12                StringBuffer sb = new StringBuffer();

13                //定义一个字符串变量

14                String st ;

15                //不等于null的时候一直读

16                while ((st = br.readLine()) != ull) {

17                    //读取的所有字符串添加到sb

18                    sb.append(st);

19                }

20                //创建第一个解析                                 需要解析的字符串

21                JSONObject first = JSONObject.fromObject(sb.toString());

22                //打印需要解析的字符串

23                System.out.println(sb.toString());

24                System.out.println("===============json第一层解析============");

25                System.out.println("msg:"+first.get("msg"));

26                System.out.println("retCode:"+first.get("retCode"));

27                System.out.println("result:"+first.get("result"));

28                

29                //创建第二个解析                               需要解析的字符串

30                JSONObject second = JSONObject.fromObject(first.get("result"));

31                System.out.println("==============json第二层解析==============");

32                System.out.println("city:"+second.get("city"));

33                System.out.println("cityCode:"+second.get("cityCode"));

34                System.out.println("mobileNumber:"+second.get("mobileNumber"));

35                System.out.println("operator:"+second.get("operator"));

36                System.out.println("province:"+second.get("province"));

37                System.out.println("zipCode:"+second.get("zipCode"));

38            } catch (IOException e) {

39                e.printStackTrace();
