cloudflare 域名脚本

脚本功能介绍

一键添加域名解析
一键修改域名解析
一键删除域名解析

申请 CloudFlare API

前往 https://dash.cloudflare.com/profile/api-tokens 登陆后,右上角选择个人资料,点击创建令牌

为了安全,用自定义令牌,没有用全局令牌。如你非要用全局令牌,请修改脚本 Authorization 全部替换为 X-Auth-Key

获取脚本

wget https://blog.wxlost.com/wp-content/uploads/2022/05/cloudFlare.sh && chmod +x cloudFlare.sh

编辑 cloudFlare.sh 内的参数(API与Email)后.运行脚本添加/更新域名的解析

bash cloudFlare.sh 域名

如需删除域名解析,使用参数1即可

bash cloudFlare.sh 域名 1

其他问题

2024年04月13日更新,添加了新的IP4和6的区分与解析过程
