使用阿里云域名作为DDNS解析

1、安装SDK

pip install aliyun-python-sdk-alidns

2、实现代码

#!/usr/bin/env python
# -*- coding: UTF-8 -*-

from aliyunsdkcore import client
from aliyunsdkalidns.request.v20150109 import DescribeDomainsRequest,DescribeDomainRecordsRequest,UpdateDomainRecordRequest
from aliyunsdkalidns.request.v20150109 import DescribeDomainRecordInfoRequest
import json,urllib,re

# 替换以下参数
access_id ="yourid"
access_key ="yourkey"
# 如果没有ECS可不用改
RegionId="cn-hangzhou"
# 一级域名,如 guoziweb.com
DomainName="guoziweb.com"
# 想要自动修改的主机名和域名类型,列表中可写多个
HostNameList = ['pub']
# A记录
Types = "A"
# 参数替换完毕

clt = client.AcsClient(access_id,access_key,RegionId)

#获取公网ip
