前端开发可以做网站赚钱吗ip或域名查询网

摘要

获取客户端ip地址，然后使用这个ip地址获取所在的国家、省份、城市，可以在网站中实现IP属地，发布地等功能。

本文的获取IP地址信息均采自网络上免费的IP查询网站，通过其API或者网页HTML解析出的ip地址信息。

使用

https://域名/getipInfo.php?ip=需要查询的IP地址

一共有5个接口，接口失效会使用下一个接口，直到接口成功，最终输出数据格式如下：

{"code":200,"msg":"获取成功","ipinfo":{"country":"中国","province":"广东省","city":"广州市","district":"番禺区","ip":"xx.xx.xxx.xx"}}
