1、开发环境
- Python 3.7.9
- Windows 10
2、开发准备
- pip3 install aliyun-python-sdk-core
- pip3 install aliyun-python-sdk-alidns
3、具体实现
''' # 思想思路： # 1、从www.jsonip.com上获取外网IP地址； # 2、从保持的Record文件中或阿里云上获取记录的Record； # 3、判断1中的IP和2中的IP是否相同，不同则更新Record； # 4、不管是否更新了DDNS都从新记录Record到文件； ''' import os; import sys; import json; import datetime;
