百度手機號碼歸屬地查詢api與返回json處理

     前天無心間在網上看到百度ApiStore，而後好奇就進去看了看。正好最近在學習Android，剛學到java基礎。抱着鍛鍊的心態選擇手機號碼歸屬地查詢api進行練手。api地址 （http://apis.baidu.com/apistore/mobilephoneservice/mobilephone）。百度官方已經給出請求示例 。咱們只須要對請求結果json進行解析就能夠。

 Java請求示例：

 1 String httpUrl = "http://apis.baidu.com/apistore/mobilephoneservice/mobilephone";
 2 String httpArg = "tel=15846530170";
 3 String jsonResult = request(httpUrl, httpArg);
 4 System.out.println(jsonResult);
 5 
 6 /**
 7  * @param urlAll
 8  *            :請求接口
 9  * @param httpArg
10  *            :參數
11  * @return 返回結果
12  */
13 public static String request(String httpUrl, String httpArg) {
14     BufferedReader reader = null;
15     String result = null;
16     StringBuffer sbf = new StringBuffer();
17     httpUrl = httpUrl + "?" + httpArg;
18 
19     try {
20         URL url = new URL(httpUrl);
21         HttpURLConnection connection = (HttpURLConnection) url
22                 .openConnection();
23         connection.setRequestMethod("GET");
24         // 填入apikey到HTTP header
25         connection.setRequestProperty("apikey",  "您本身的apikey");
26         connection.connect();
27         InputStream is = connection.getInputStream();
28         reader = new BufferedReader(new InputStreamReader(is, "UTF-8"));
29         String strRead = null;
30         while ((strRead = reader.readLine()) != null) {
31             sbf.append(strRead);
32             sbf.append("\r\n");
33         }
34         reader.close();
35         result = sbf.toString();
36     } catch (Exception e) {
37         e.printStackTrace();
38     }
39     return result;
40 }

      咱們要作的是進行對請求返回結果result處理，百度給出了返回結果爲json，那麼就要對json進行解析輸出。

      百度給出的json返回示例：

1 {
2 errNum: 0,
3 errMsg: "success",
4 retData: {
5    telString: "15846530170", //手機號碼
6    province: "黑龍江",    //省份
7    carrier: "黑龍江移動"  //運營商
8   }
9 }

     對json解析須要用到json-lib.jar包，網上能夠百度到。

     json解析核心代碼:

  1 JSONObject obj = JSONObject.fromObject(jsonResult1); 2 String errNum = obj.getString("errNum"); 

     演示示例：

 

 1 package day02;
 2 
 3 import java.io.BufferedReader;
 4 import java.io.InputStream;
 5 import java.io.InputStreamReader;
 6 import java.net.HttpURLConnection;
 7 import java.net.URL;
 8 import net.sf.json.JSONObject;

10 public class Test11 {

12     /**
13      * 查詢手機號碼歸屬地
14      * @param args
15      */
16     public static void main(String[] args) {
17         // TODO Auto-generated method stub
18 
19         String httpUrl = "http://apis.baidu.com/apistore/mobilephoneservice/mobilephone";
20         String httpArg = "tel=15768798455";
21         String jsonResult1 = request(httpUrl, httpArg);
22         System.out.println(jsonResult1);
23         JSONObject obj = JSONObject.fromObject(jsonResult1);
24          String errNum = obj.getString("errNum");
25          System.out.println(errNum);
26          String errMsg = obj.getString("errMsg");
27          System.out.println(errMsg);
28          String retData = obj.getString("retData");
29          JSONObject obj2 = JSONObject.fromObject(retData);
30          String telString = obj2.getString("telString");
31          String province = obj2.getString("province");
32          String carrier = obj2.getString("carrier");
33          System.out.println("你查詢號碼："+telString+"\n"+"歸屬地："+province+"\n"+"運營商："+carrier);

35     }

44     public static String request(String httpUrl, String httpArg) {
45         BufferedReader reader = null;
46         String result = null;
47         StringBuffer sbf = new StringBuffer();
48         httpUrl = httpUrl + "?" + httpArg;
49 
50         try {
51             URL url = new URL(httpUrl);
52             HttpURLConnection connection = (HttpURLConnection) url
53                     .openConnection();
54             connection.setRequestMethod("GET");
55             // 填入apikey到HTTP header
56             connection.setRequestProperty("apikey",
57                     "你的百度api祕鑰");
58             connection.connect();
59             InputStream is = connection.getInputStream();
60             reader = new BufferedReader(new InputStreamReader(is, "UTF-8"));
61             String strRead = null;
62             while ((strRead = reader.readLine()) != null) {
63                 sbf.append(strRead);
64                 sbf.append(strRead + " ");

70         }
71         return result;

 輸出結果：

2 錯誤碼：0
3 錯誤碼返回：success
4 你查詢號碼：15737954118
5 歸屬地：河南
6 運營商：河南移動

 

自此百度手機號碼歸屬地api體驗成功結束，也是實訓期間的練手。
