目的

远程控制家里的Windows系统电脑。

准备

阿里云域名

家里电脑所在网络有公网IP

Python环境（我安装的为版本为3.6.8）

内容

在阿里云后台https://ram.console.aliyun.com/manage/ak 获取AccessKey ID和AccessKey Secret。

安装依赖包

pip3 install aliyun-python-sdk-core-v3 
pip3 install aliyun-python-sdk-domain 
pip3 install aliyun-python-sdk-alidns 
pip3 install requests

    time.sleep(5) #5秒后

我用的是ipv6，保存文件 aliyunddns.py。

添加到任务计划，设定每X分钟执行一次。

运行效果：
