     前天无意间在网上看到百度ApiStore,然后好奇就进去看了看。正好最近在某博培训Android,刚学到java基础。抱着锻炼的心态选择手机号码归属地查询api进行练手。api地址 (http://apis.baidu.com/apistore/mobilephoneservice/mobilephone)。百度官方已经给出请求示例 。我们只需要对请求结果json进行解析就可以。

 Java请求示例:

 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  *            :请求接口
 9  * @param httpArg
10  *            :参数
11  * @return 返回结果
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",  "您自己的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 }

      我们要做的是进行对请求返回结果result处理,百度给出了返回结果为json,那么就要对json进行解析输出。

      百度给出的json返回示例:

1 {
2 errNum: 0,
3 errMsg: "success",
4 retData: {
5    telString: "15846530170", //手机号码
6    province: "黑龙江",    //省份
7    carrier: "黑龙江移动"  //运营商
8   }
9 }

     对json解析需要用到json-lib.jar包,网上可以百度到。

     json解析核心代码:

  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;
 9 
10 public class Test11 {
11 
12     /**
13      * 查询手机号码归属地
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("你查询号码:"+telString+"\n"+"归属地:"+province+"\n"+"运营商:"+carrier);
34 
35     }
36 
37     /**
38      * @param urlAll
39      *            :请求接口
40      * @param httpArg
41      *            :参数
42      * @return 返回结果
43      */
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秘钥");
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 + " ");
65             }
66             reader.close();
67             result = sbf.toString();
68         } catch (Exception e) {
69             e.printStackTrace();
70         }
71         return result;
72     }
73 
74 }

 

 输出结果:

 

 

1 {"errNum":0,"errMsg":"success","retData":{"telString":"15737954118","province":"\u6cb3\u5357","carrier":"\u6cb3\u5357\u79fb\u52a8"}}{"errNum":0,"errMsg":"success","retData":{"telString":"15737954118","province":"\u6cb3\u5357","carrier":"\u6cb3\u5357\u79fb\u52a8"}} 
2 错误码:0
3 错误码返回:success
4 你查询号码:15737954118
5 归属地:河南
6 运营商:河南移动

 

自此百度手机号码归属地api体验成功结束,也是实训期间的练手。
