【群晖】自动获取动态IPV4并解析到阿里云域名

首先需要你的域名是在阿里云进行解析使用的才行

获取阿里云的权限

登录控制台，在头像下面进入 “AccessKey管理” 页面
为了安全原因，建议在“用户”-“创建用户”中创建一个专用帐号（需要对子帐号设置单独的权限，否则无法正常操作API）
创建成功后会出现下面的页面，页面中右侧会显示 AccessKey ID 和 AccessKey Secret ，找地方保存值，后面会用到
返回用户管理页面，选择刚才创建的用户，选择添加权限
点击“域名”相关的权限添加到右侧中
点击“解析”相关的权限并添加
保存并退出权限页面

编写脚本

注意修改 if name == 'main' 方法中的各个参数值

根据实际需求修改 def __execute() 方法中的各项属性值

修改__execute方法中的your.domain为你自己的站点域名
