java 根据IP地址获取地理位置
一、第三方API
ps:下面参数ip: 218.192.3.42 用于测试
- 淘宝API:http://ip.taobao.com/service/getIpInfo.php?ip=218.192.3.42
- 新浪API:http://int.dpool.sina.com.cn/iplookup/iplookup.php?format=json&ip=218.192.3.42
- pconline API:http://whois.pconline.com.cn/
- 百度API:http://api.map.baidu.com/location/ip?ip=218.192.3.42
二、工具类
AddressUtils.java

- import java.io.DataOutputStream;
- import java.io.IOException;
- import java.io.InputStreamReader;
- import java.io.UnsupportedEncodingException;
- import java.net.HttpURLConnection;

- e.printStackTrace();
- }
- System.out.println(address);
- // 输出结果为:广东省,广州市,越秀区

- }
三、 测试方法
下面采用单元测试
- @Test
- public void getAddressByIp() throws Exception {
- // 参数ip
- String ip = "219.136.134.157";
- // json_result用于接收返回的json数据
- String json_result = null;
- try {
- json_result = AddressUtils.getAddresses("ip=" + ip, "utf-8");
- } catch (UnsupportedEncodingException e) {
- e.printStackTrace();
- }
- JSONObject json = JSONObject.fromObject(json_result);
- System.out.println("json数据: " + json);
- String country = JSONObject.fromObject(json.get("data")).get("country").toString();
- String region = JSONObject.fromObject(json.get("data")).get("region").toString();
- String city = JSONObject.fromObject(json.get("data")).get("city").toString();
- String county = JSONObject.fromObject(json.get("data")).get("county").toString();
- String isp = JSONObject.fromObject(json.get("data")).get("isp").toString();
- String area = JSONObject.fromObject(json.get("data")).get("area").toString();
- System.out.println("国家: " + country);
- System.out.println("地区: " + area);
- System.out.println("省份: " + region);
- System.out.println("城市: " + city);
- System.out.println("区/县: " + county);
- System.out.println("互联网服务提供商: " + isp);
- String address = country + "/";
- address += region + "/";
- address += city + "/";
- address += county;
- System.out.println(address);
- }
四、 打印结果
下面是eclipse控制台的打印结果
(1) unicode转换成中文前的
- returnStr : {"code":0,"data":{"country":"u4e2du56fd","country_id":"CN","area":"u534eu5357","area_id":"800000","region":"u5e7fu4e1cu7701","region_id":"440000","city":"u5e7fu5ddeu5e02","city_id":"440100","county":"u8d8au79c0u533a","county_id":"440104","isp":"u7535u4fe1","isp_id":"100017","ip":"219.136.134.157"}}
(2) unicode转换成中文后的
- returnStr : {"code":0,"data":{"country":"中国","country_id":"CN","area":"华南","area_id":"800000","region":"广东省","region_id":"440000","city":"广州市","city_id":"440100","county":"越秀区","county_id":"440104","isp":"电信","isp_id":"100017","ip":"219.136.134.157"}}
- json数据: {"code":0,"data":{"country":"中国","country_id":"CN","area":"华南","area_id":"800000","region":"广东省","region_id":"440000","city":"广州市","city_id":"440100","county":"越秀区","county_id":"440104","isp":"电信","isp_id":"100017","ip":"219.136.134.157"}}
