摘要
获取客户端ip地址，而后应用这个ip地址获取所在的国家、省份、城市，能够在网站中实现IP属地，公布地等性能。
本文的获取IP地址信息均采自网络上收费的IP查问网站，通过其API或者网页HTML解析出的ip地址信息。
代码
<?php // 编码 header('Content-type:application/json'); $ip = $_GET['ip']; // 过滤空数据 if(!$ip) { $ipinfo = array( 'code' => 201, 'msg' => '未传入ip地址' ); echo json_encode($ipinfo,JSON_UNESCAPED_UNICODE); exit;

https://域名/getipInfo.php?ip=须要查问的IP地址
一共有5个接口，接口生效会应用下一个接口，直到接口胜利，最终输入数据格式如下：
{"code":200,"msg":"获取胜利","ipinfo":{"country":"中国","province":"广东省","city":"广州市","district":"番禺区","ip":"xx.xx.xxx.xx"}}作者
