java根据ip地址获取详细地域信息的方法

java根据ip地址获取详细地域信息的⽅法
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
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。

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\u5b6通过jqry 获取相应的数据
$.getScript(‘数据接⼝',function(){
//新浪：remote_ip_info.country
})
