【Python】阿里云DDNS动态域名解析，无需SDK
本帖最后由 辣丝丝小白菜 于 2020-11-4 11:42 编辑阿里云DDNS动态域名解析-易语言版：https://www.52pojie.cn/thread-1294027-1-1.html
阿里云DDNS动态域名解析-PythonSDK版：https://www.52pojie.cn/thread-783673-1-1.html
此版本不需要专门下载阿里云的SDK，一个文件即可，已经集成了鉴权等操作。

这个是用来干嘛用的，是内网穿透吗 还是自己家里搭建服务 upnp DMZ
开了 公网IP后，可以把域名解析到自己的电脑/NAS。但是自己的网络IP地址不固定，经常换，这个就是检测公网IP 然后自动更新解析。 这个是用来干嘛用的，是内网穿透吗 还是自己家里搭建服务 upnp DMZ 这个有什么用呢，爬取淘宝数据吗？ 电信的打客服电话30分钟直接就开通了不懂就问，这个 要怎么说呢 …… 厉害的人物，来学习 小小欣 发表于 2020-11-4 17:50
电信的打客服电话30分钟直接就开通了不懂就问，这个 要怎么说呢
就说 要做监控 要开公网IP ，远程监控之类的 怎么用啊？没看明白
这个很厉害，收藏了
