大家好，我是新来的，今天分享一个基于Cloudflare自带的IP地理位置库，实现类似ip.sb功能的脚本。
功能：显示IP地址、定位、ASN信息、你的User Agent和CF数据中心；
声明：借鉴了ip.sb与ip.p3terx.com
测试： 因害怕被刷不提供测试
先上效果：
curl:
root@OVH:~# curl ip.YOUR_DOMAIN2607:5300:60:x:x:x:791e:a3bf # IP地址Beauharnois, Quebec, CA # 定位AS16276 / OVH Hosting # 运营商curl/7.88.1 # 你的User AgentYUL # CF 数据中心root@OVH:~# curl ip.YOUR_DOMAIN -4192.99.x.yL**al, Quebec, CAAS16276 / OVHcloudcurl/7.88.1YYZ使用方法：在Workers & Pages中新建一个"Hello world"的Workers，然后复制粘贴进去替换即可.
上代码：
