Java ip地址查询,根据ip接口获得ip所在省市区,邮编,运营商等

互联网有很多接口可以实现通过ip查询到具体的位置，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":"u4e2du56fd","area":"u534eu5317",

"region":"u5317u4eacu5e02","city":"u5317u4eacu5e02","county":"","isp":"u7535u4fe1",

"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":"u4e2du56fd","province":"u5e7fu4e1c","city":"u5e7fu5dde","district":"","isp":"u6559u80b2u7f51","type":"u5b66u6821","desc":"u5e7fu5ddeu5927u5b66u7ebau7ec7u670du88c5u5b66u9662"};

通过jqry 获取相应的数据

$.getScript('数据接口',function(){

//新浪：remote_ip_info.country

}) 

腾讯IP分享计划的地址获取IP所在地：

用java调用淘宝ip查询接口查询地域的一个java实例：
