Python實現阿里雲域名DDNS

阿新 • • 發佈：2020-10-22

前言

通過阿里雲的SDK來新增修改域名解析，檢查本機IP與解析的IP是否一致，若不同則自動修改解析，達到動態解析的目的，主要用於家庭寬頻這些動態IP的地方。

首先

IP必須為公網ip
阿里域名

詳細步驟

獲取accessKeyId和accessSecret

可以在阿里雲控制檯個人中心直接獲取。建議使用RAM角色來進行許可權控制，這樣的話安全風險較小。

安裝對應的依賴包

pip3 install aliyun-python-sdk-core-v3 
pip3 install aliyun-python-sdk-domain 
pip3 install aliyun-python-sdk-alidns 
pip3 install requests
//本人使用的是Python3

使用指令碼
