Python实现阿里云域名DDNS

前言

通过阿里云的SDK来添加修改域名解析，检查本机IP与解析的IP是否一致，若不同则自动修改解析，达到动态解析的目的，主要用于家庭宽带这些动态IP的地方。

首先：

IP必须为公网ip
阿里域名

详细步骤

获取accessKeyId和accessSecret

可以在阿里云控制台个人中心直接获取。建议使用RAM角色来进行权限控制，这样的话安全风险较小。

安装对应的依赖包

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

使用脚本

  1 from aliyunsdkcore.client import AcsClient
  2 from aliyunsdkcore.acs_exception.exceptions import ClientException
  3 from aliyunsdkcore.acs_exception.exceptions import ServerException
  4 from aliyunsdkalidns.request.v20150109.DescribeSubDomainRecordsRequest import DescribeSubDomainRecordsRequest

  6 import requests
  7 from urllib.request import urlopen
  8 import json

 10 ipv4_flag = 1  # 是否开启ipv4 ddns解析,1为开启，0为关闭
 11 ipv6_flag = 0  # 是否开启ipv6 ddns解析,1为开启，0为关闭
 12 accessKeyId = "accessKeyId"  # 将accessKeyId改成自己的accessKeyId
 13 accessSecret = "accessSecret"  # 将accessSecret改成自己的accessSecret
 14 domain = "baidu.com"  # 你的主域名
 15 name_ipv4 = "www"  # 要进行ipv4 ddns解析的子域名
 16 name_ipv6 = "ipv6.test"  # 要进行ipv6 ddns解析的子域名
