创建win后台任务定时用Python代码发邮件

　　1、先根据自己的需求完成邮件发送python任务测试import docx from smtplib import SMTP_SSL from email.mime.text import MIMEText from email.mime.multipart import MIMEMultipart from email.header import Header from email.mime.application import MIMEApplication from apscheduler.schedulers.blocking import BlockingScheduler  from loguru import logger import yaml # 添加日志记录 logger.add(＂info.log＂, format=＂{time:YYYY-MM-DD at HH:mm:ss} | {level} | {message}＂, level=＂INFO＂, rotation=＂500 MB＂, encoding=＂utf-8＂) logger.add(＂error.log＂, format=＂{time:YYYY-MM-DD at HH:mm:ss} | {level} | {message}＂, level=＂ERROR＂, rotation=＂500 MB＂, encoding=＂utf-8＂)  def sz_task():     with open(r＂配置yaml文件路径＂, encoding=＂utf-8＂) as emailFile:         conf = yaml.load(emailFile)     # 邮箱stmp域名     host_server = conf[＂host_server＂]     # 发送者邮箱     sender_mail = conf[＂sender_mail＂]     # 授权码     pwd = conf[＂pwd＂]     # 接收者邮箱列表     receivers_mail = conf[＂receivers_mail＂]     # 抄送者邮箱列表     cc_mail = conf[＂cc_mail＂]        file = docx.Document(r＂附件文件路径＂)     title = 邮件标题     mail_content = 邮件正文拼接     msg = MIMEMultipart(＂mixed＂)     msg[＂Subject＂] = Header(title, ＂utf-8＂)     msg[＂From＂] = sender_mail     msg[＂To＂] = ＂;＂.join(receivers_mail)     msg[＂Cc＂] = ＂;＂.join(cc_mail)        body = MIMEText(mail_content, ＂plain＂)     msg.attach(body)     with open(r＂附件文件路径＂, ＂rb＂) as f:         attachment = MIMEApplication(f.read())     attachment.add_header(＂Content-Disposition＂, ＂attachment＂, filename=附件文件名)     msg.attach(attachment)      try:         smtp = SMTP_SSL(host_server, 465)         smtp.set_debuglevel(1)         smtp.login(sender_mail, pwd)         smtp.sendmail(sender_mail, receivers_mail + cc_mail, msg.as_string())          logger.info(＂发送成功＂)     except:              logger.error(＂发送失败＂)  # 定时任务 def shedu_task():     sheduler = BlockingScheduler()     sheduler.add_job(sz_task, ＂cron＂, hour=XX, minute=XX)     try:         sheduler.start()     except (KeyboardInterrupt, SystemExit):         pass  if __name__ == ＂__main__＂:     shedu_task()2、使用pyinstaller工具将py文件打包成exe文件pip install pyinstaller
　　然后打包exe文件 pyinstaller -F XX.py3、使用sc工具写成win服务，后台启动
　　打开powershell，输入以下 sc.exe create 服务名自定义 binPath=＂EXE文件路径＂ net start 服务名自定义 //启动服务或者在任务管理起启用 sc.exe delete 服务名自定义 //删除后台服务（选）
