前言

由于自己用了多WAN,一直没找到合适的ddns插件,所以用cloudflare api^[1]实现了一个ddns功能

代码

#!/bin/sh
[ $ACTION = "ifup" -a $INTERFACE = "WAN" ]
ip=`ubus call network.interface.WAN status | grep \"address\" | grep -oE '[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}'`
curl -X PUT "https://api.cloudflare.com/client/v4/zones/xxxxxxxxx/dns_records/xxxxxxxx" -H "Authorization: Bearer XXXXXXXXXXX"  -H "Content-Type: application/json" --data '{"type":"A","name":"domian.test","content":"'$ip'","ttl":120,"priority":10,"proxied":false}' > /dev/null                                               

将以上文件保存为30-cloudflare 放置在/etc/hotplug.d/iface目录下

注:xxx替换为自己的设置,token长期有效^[2],可以固定写死.
