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GEThttp://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
