1. 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

3. 测试方法
下面采用单元测试
[java] view plain copy
@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);
}
4. 打印结果
下面是eclipse控制台的打印结果
[plain] view plain copy
(1) unicode转换成中文前的returnStr : {"code":0,"data":{"country":"\u4e2d\u56fd","country_id":"CN","area":"\u534e\u5357","area_id":"800000","region":"\u5e7f\u4e1c\u7701","region_id":"440000","city":"\u5e7f\u5dde\u5e02","city_id":"440100","county":"\u8d8a\u79c0\u533a","county_id":"440104","isp":"\u7535\u4fe1","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"}}
