因为自己网站后台做了一个进站ip统计，之前只是获取了ip，这次优化了下，把ip的大致区域弄出来了
废话不多说，进正题
首先要用到几个网络大头的api
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=218.192.3.42pconline API：http://whois.pconline.com.cn/百度API：http://api.map.baidu.com/location/ip?ip=218.192.3.42接下来用json解析返回的数据就好下面直接上解析源码（不是网站的源码，是之前java测试的源码，原理一样）
package exe; import net.sf.json.JSONObject; import java.io.BufferedReader; import java.io.IOException; import java.io.InputStreamReader; import java.net.HttpURLConnection; import java.net.URL; import java.util.Scanner; /** * 通过淘宝的API来获取指定IP的定位 */ /** * 各种API接口 * 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 */ public class get_analyse_ip { /** * 涉及到解析json */ public static void main(String[] args) { HttpURLConnection connection ; String api = "http://ip.taobao.com/service/getIpInfo.php"; String connect_symbol = "?"; String front_name = "ip="; Scanner sc = new Scanner(System.in); String real_ip = sc.next(); URL url ; BufferedReader bf ; StringBuffer sb = new StringBuffer(); try { url = new URL(api+connect_symbol+front_name+real_ip); connection = (HttpURLConnection)url.openConnection(); bf = new BufferedReader(new InputStreamReader(connection.getInputStream(),"utf-8")); String line = ""; while(null!=(line = bf.readLine())){ sb.append(line); } } catch (IOException e) { e.printStackTrace(); } // System.out.println(sb); JSONObject dataObject = JSONObject.fromObject(sb.toString()); JSONObject jsonObject= dataObject.getJSONObject("data"); System.out.println(jsonObject.toString()); System.out.println("ip:"+jsonObject.get("ip")); System.out.println("country:"+jsonObject.get("country")); System.out.println("area:"+jsonObject.get("area")); System.out.println("region:"+jsonObject.get("region")); System.out.println("county:"+jsonObject.get("county")); System.out.println("isp:"+jsonObject.get("isp")); System.out.println("city:"+jsonObject.get("city")); System.out.println("country_id:"+jsonObject.get("country_id")); System.out.println("area_id:"+jsonObject.get("area_id")); System.out.println("region_id:"+jsonObject.get("region_id")); System.out.println("city_id:"+jsonObject.get("city_id")); System.out.println("county_id:"+jsonObject.get("county_id")); System.out.println("isp_id:"+jsonObject.get("isp_id")); } } 要导入json第三方jar包，方法自行百度，在此不赘述
希望对大家有所帮助
