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。

应用
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"}}
