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
