Java ip地址查詢,根據ip接口獲得ip所在省市區,郵編,運營商等

互聯網有很多接口可以實現通過ip查詢到具體的位置，如下：

通過淘寶IP地址庫獲取IP位置

1. 請求接口（GET）：http://ip.taobao.com/service/getIpInfo.php?ip=[ip地址字串]

2. 響應信息：（json格式的）國家 、省（自治區或直轄市）、市（縣）、運營商

3. 返回數據格式：

{"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的值的含義為，0：成功，1：失敗。 

 

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"};

通過jqry 獲取相應的數據

$.getScript('數據接口',function(){

//新浪：remote_ip_info.country

}) 

騰訊IP分享計划的地址獲取IP所在地：

http://ip.qq.com/cgi-bin/searchip?searchip1=ip
