Python实现阿里云域名DDNS

前言

  • 通过阿里云的SDK来添加修改域名解析,检查本机IP与解析的IP是否一致,若不同则自动修改解析,达到动态解析的目的,主要用于家庭宽带这些动态IP的地方。

首先

  • IP必须为公网ip

  • 阿里域名

详细步骤

  • 获取accessKeyId和accessSecret

                  可以在阿里云控制台个人中心直接获取。建议使用RAM角色来进行权限控制,这样的话安全风险较小。

  •  安装对应的依赖包

    pip3 install aliyun-python-sdk-core-v3 
    pip3 install aliyun-python-sdk-domain
    pip3 install aliyun-python-sdk-alidns
    pip3 install requests
    //本人使用的是Python3
  • 使用脚本

           复制代码,然后使用编辑器打开,按照注释提示修改并保存。

  • 运行代码  

       运行代码

     

  • 设置定时运行代码  

      设置定时运行,方法自行百度(主要是自己百度出来的没有成功)
         本人安装了宝塔面板于是直接在宝塔面板设置定时即可
