python脚本

参考：linux服务器开机发送本机ip地址到指定邮箱

import socket

from email.header import Header
from email.mime.multipart import MIMEMultipart
from email.mime.text import MIMEText
from time import asctime

# ipv4 = socket.gethostbyname(socket.gethostname())
# print(ipv4)

    mail_host = "smtp.qq.com" # 这个去邮箱找
    mail_user = "xxxxxx@qq.com" # 邮箱名
    mail_auth_code = "xxxxxxxxxxxxxxxx" # 授权码
    mail_sender = mail_user # 用mail_user 作为发送人
    mail_receivers = ["xxxxxx@qq.com"]
    message = MIMEMultipart()
    message['From'] = Header(mail_sender)  # 寄件人
    message['Subject'] = Header("笔记本当前ip地址")
    message.attach(MIMEText(asctime(), 'plain', 'utf-8'))
    message.attach(MIMEText(email_content, 'plain', 'utf-8'))
    print("message is {}".format(message.as_string())) # debug用
    smtpObj = smtplib.SMTP(mail_host)
    # smtpObj.set_debuglevel(1) # 同样是debug用的
    smtpObj.login(mail_user, mail_auth_code) # 登陆
    smtpObj.sendmail(mail_sender, mail_receivers, message.as_string()) # 真正发送邮件就是这里

# 判断ip是否有变化，仅在变化时发送

windows下自动执行

1. windows计划任务设置，windows定时任务设置，每5分钟，30分钟，1小时，每天执行一次，类似linux crontab
2. windows 10 如何设定计划任务自动执行 python 脚本？
3. Windows创建定时任务执行Python脚本
4.
