这篇文章主要介绍了java根据ip地址获取详细地域信息的方法，小编觉得挺不错的，现在分享给大家，也给大家做个参考。一起跟随小编过来看看吧
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
请求接口（GET）：http://www.php.cn/[ip地址字串]
响应信息：（json格式的）国家 、省（自治区或直辖市）、市（县）、运营商
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://www.php.cn/
返回值
复制代码 代码如下:
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
})腾讯IP分享计划的地址获取IP所在地： http://www.php.cn/
用Java调用淘宝ip查询接口查询地域的一个java实例：
