JAVA根据IP地址获取详细的地域信息

2014-01-11 15:19 381 查看
在系统中,网站的头部一般都有显示是哪个城市的,用户进入到网站的首页后,默认城市应该是用户本地的城市信息,例如:北京,网站就要根据你的IP地址的信息,查询数据,获取北京部分的数据,呵呵,当然我可能描述的不是很清楚,但是可以理解成,通过IP地址定位地理信息就行。很多人现在使用以QQ数据库为基础获取地址信息,但不完整、而且不规范。互联网提供很多其他接口可以完成这项功能.
接口如下:

通过淘宝IP地址库获取IP位置

1. 请求接口(GET):http://ip.taobao.com/service/getIpInfo.php?ip=[ip地址字串]
2. 响应信息:(json格式的)国家 、省(自治区或直辖市)、市(县)、运营商
3. 返回数据格式:
{"code":0,"data":{"ip":"210.75.225.254","country":"\u4e2d\u56fd","area":"\u534e\u5317",

"region":"\u5317\u4eac\u5e02","city":"\u5317\u4eac\u5e02","county":"","isp":"\u7535\u4fe1",

"country_id":"86","area_id":"100000","region_id":"110000","city_id":"110000",

"county_id":"-1","isp_id":"100017"}}
其中code的值的含义为,0:成功,1:失败。

新浪的接口 :http://int.dpool.sina.com.cn/iplookup/iplookup.php?format=json&ip=218.192.3.42

返回值
var remote_ip_info = {"ret":1,"start":"218.192.0.0","end":"218.192.7.255","country":"\u4e2d\u56fd","province":"\u5e7f\u4e1c","city":"\u5e7f\u5dde","district":"","isp":"\u6559\u80b2\u7f51","type":"\u5b66\u6821","desc":"\u5e7f\u5dde\u5927\u5b66\u7eba\u7ec7\u670d\u88c5\u5b66\u9662"};

通过jqry 获取相应的数据
$.getScript('数据接口',function(){
//新浪:remote_ip_info.country
})

根据腾讯IP分享计划的地址获取IP所在地

示例:

package com.gxy.weixin.util;

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