Python实现阿里云域名DDNS

时间：2024-01-31 16:40:46

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

    from aliyunsdkcore.client import AcsClient
from aliyunsdkcore.acs_exception.exceptions import ClientException
from aliyunsdkcore.acs_exception.exceptions import ServerException
from aliyunsdkalidns.request.v20150109.DescribeSubDomainRecordsRequest import DescribeSubDomainRecordsRequest

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

           复制代码,然后使用编辑器打开，按照注释提示修改并保存。

  • 运行代码  

     　　运行代码

     

  • 设置定时运行代码  

     　设置定时运行,方法自行百度（主要是自己百度出来的没有成功）
         本人安装了宝塔面板于是直接在宝塔面板设置定时即可
