依赖：
树莓派3b 万网域名（需要申请APIkey）
python3 模块:
requests aliyun-python-sdk-core-v3 aliyun-python-sdk-alidns
脚本如下：
import requests import json from aliyunsdkcore.client import AcsClient from aliyunsdkcore.acs_exception.exceptions import ClientException from aliyunsdkcore.acs_exception.exceptions import ServerException from aliyunsdkalidns.request.v20150109 import UpdateDomainRecordRequest, DescribeDomainRecordInfoRequest DOMAIN = \\\’*.com\\\’ RID = \\\’该域名的rid\\\’ client = AcsClient( "appkey", "appsecret", "cn-hangzhou" ) def ip(): #自己写的获取源 IP服务 r = requests.get(\\\’http://*.*.com/get/ip\\\’) if r.status_code == 200: return r.text else: return None def update_record(cip, old): update_pi(cip) req = UpdateDomainRecordRequest.UpdateDomainRecordRequest() req.set_RecordId(RID) req.set_RR(old[\\\’RR\\\’]) req.set_Type(old[\\\’Type\\\’]) req.set_Value(cip) resp = client.do_action_with_exception(req) print(resp) return True def update_pi(cip): postdata = {\\\’ip\\\’: ip} #自己写的记录IP变化的web服务 r = requests.post(\\\’http://*.*.com/pi/ip\\\’, data=postdata) return r.text == \\\’ok\\\’ def connect_dns(): cip = ip() if not cip: return False req = DescribeDomainRecordInfoRequest.DescribeDomainRecordInfoRequest() req.set_RecordId(RID) resp = client.do_action_with_exception(req).decode(\\\’utf-8\\\’) old = json.loads(resp) if cip == old[\\\’Value\\\’]: return True else: return update_record(cip, old) if __name__ == \\\’__main__\\\’: connect_dns()
然后放置在crontab 每半个小时执行一次，用来自动检测和更新
