阿里云域名 动态ip绑定 python方案

一、配置config.json二、代码三、打包执行
思路：阿里云提供dns域名解析api，查出外网ip，定时更新域名解析。

用配置文件，动态配置二级域名，ip，accessKey等。

{
  "ip": "223.76.234.68",
  "accessKeyId": "", //阿里云控制台生成
  "accessSecret": "",
  "domain": "xxx.com.cn", //一级域名
  "subDomain": "test",    //二级域名前缀，多个用英文逗号隔开
  "time": "6"  //定时更新，秒
}

python3依赖：

pip install requests
pip install aliyun-python-sdk-alidns
pip install aliyun-python-sdk-core
pip install aliyun-python-sdk-domain

代码：

import json
import time

import requests
from aliyunsdkalidns.request.v20150109.AddDomainRecordRequest import AddDomainRecordRequest
from aliyunsdkalidns.request.v20150109.DescribeSubDomainRecordsRequest import DescribeSubDomainRecordsRequest
from aliyunsdkalidns.request.v20150109.UpdateDomainRecordRequest import UpdateDomainRecordRequest
from aliyunsdkcore.client import AcsClient

window服务器
安装Pyinstaller，在项目目录中执行

Pyinstaller -D -w main.py 

并将配置文件放到dist/main目录中，单击mian.exe即可（可能会被杀毒 软件杀掉），
