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.BufferedReader;
import java.io.DataOutputStream;
import java.io.IOException;
import java.io.InputStreamReader;
import java.io.UnsupportedEncodingException;
import java.net.HttpURLConnection;
import java.net.URL;

// 测试

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\"}}
