第一步：拥有阿里云域名，设置阿里云域名管理账号

转载自：https://www.jianshu.com/p/b8e01206f58c
1.1 登录阿里云控制台
1.2 在产品与服务中搜“访问控制”

1.3 创建新用户，只勾选编程访问。
这里要记住AccessKeyID和AccessKey Secret，后面需要用到。

1.4 添加DNS管理权限
找到AliyunDNSFullAccess权限，并添加。

第二步：新建加载运行python文件

参考：https://blog.zeruns.tech/archives/507.html
实际使用时会遇到请求超时等情况.
作出了一些代码的修改：（目前只修改了ipv4，ipv6自行参考修改~）
1.在超时时不再请求。
2.断网重连
1.环境安装：
python环境

2.需要安装的库：

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

3.新建aliddns.py文件，修改配置：

accessKeyId = "xxx"  # 将accessKeyId改成自己的accessKeyId
accessSecret = "xxx"  # 将accessSecret改成自己的accessSecret
domain = "xxx.cn"  # 你的主域名
name_ipv4 = "xxx"  # 要进行ipv4 ddns解析的子域名
name_ipv6 = ""  # 要进行ipv6 ddns解析的子域名

4.用cmd运行aliddns.py文件
改进后的aliddns.py文件
添加了ping IP的方法get_external_ip()，用来防止ip检测的网站挂掉。
