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

• 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
