# --------------------------------------------------------------
#	项目: 基于better-cloudflare-ip的 N1 自动更新 IP
#	版本: 1.4.0
#	更新日期：2022-4-13
#	作者: 鸿煊
#	项目: https://github.com/Lbingyi/cf-autoupdate
#	使用说明：加在openwrt上系统--计划任务里添加定时运行，如0 9 * * * bash /mnt/mmcblk2p4/cf-openwrt/cf-openwrt.sh
#	*解释：9点0分运行一次。
#	路由上的爬墙软件节点IP全部换成路由IP，如192.168.1.1:8443，端口全部8443
#	使用前请更换自己的推送token 注册地址下下方
