定时获取公网ip并发送邮件提醒

前一段时间路由器刷的老毛子固件“穿透服务”中定时更新阿里DDNS失败了，用了很久第一次遇到。所以需要做个备用的措施用来实时获取公网ip信息

1、基于python实现

开启邮箱的SMTP功能
拿到授权码(不是登录密码)

2、创建bat文件启动脚本

"D:\Program Files\Python310\python.exe" D:\Code\Code\sendWANIP\sendWANIP.py

3、Windows任务计划

添加windows任务计划，每隔10分钟执行bat文件获取公网ip
注意：

“程序或脚本”中写的可执行文件不要被引号包裹
起始位置必填，为可执行文件所在的目录否则无法执行

4、shell脚本

路由器上跑的shell脚本，百度得来的出处忘记了，有需要的可以参考

#!/bin/bash
 
#SMTP配置   #（例子）
#SMTP服务器#smtpserver=smtp.126.com
#邮箱账号#fromaddress=xxxxxx@126.com
#邮箱密码fromaddresspwd=xxxxxxxxxxxxx
#收件人信息#toaddress=xxxxxx@qq.com 英文逗号分隔
 
 
 
#SMTP配置
smtpserver=smtp.163.com
fromaddress=xxxx@163.com
fromaddresspwd=xxxxxxxxxxxxx
toaddress=xxxxx@163.com
 
 
 
#文件路径，最新ip写入lastwanip.txt
