python通过微信发送邮件实现电脑关机

Python 通过微信邮件实现电脑关机，供大家参考，具体内容如下

通过手机微信发送QQ邮件给sina邮箱，然后利用python的pop3定时检查sina邮箱的邮件主题以及邮件来源，并在电脑执行相应的命令行实现关机。

Email_test【V1.0】

import poplib
import os
import time
from email.parser import Parser
from email.header import decode_header
from email.utils import parseaddr 

#编码转换函数
def decode_str(s):
  value, charset = decode_header(s)[0]
  if charset:
    value = value.decode(charset)
  return value 

#获取email主题
def get_Subject(msg):
  #提取Subject信息
  Subject = msg.get('Subject')
  #编码转换
  Subject = decode_str(Subject)
  return Subject 

def judge(Subject, e_addr):
  if (Subject == '关机' and e_addr == '532101629@qq.com'):
    return 1
  else:
    return 0 

#检索邮件主题
def Check_Subject(host, user, password):
  result = 0
  try:
    pop_connect = poplib.POP3(host=host, timeout=3)
    print(pop_connect.getwelcome()) 

    pop_connect.user(user)
    pop_connect.pass_(password)
    print('Messages: %s. Size: %s' % pop_connect.stat()) 

    #服务器返回信息，消息列表，返回信息的大小。
    number = len(pop_connect.list()[1])
    print('消息列表长度：', number) 

    #检索所有邮件
    for index in range(1, number+1):
      #获取第一封邮件信息
      msglines = pop_connect.retr(index)[1]
      # 可以获得整个邮件的原始文本(重新排版后的):
      str = b'\r\n'
      msg_content = str.join(msglines).decode('utf-8')
      print('\n', msg_content)
      #将原始邮件转换为email实例:
      msg = Parser().parsestr(msg_content) 

      # 获取email主题
      Subject = get_Subject(msg)
      print(Subject)
      # 获取email地址
      email_addr = parseaddr(msg.get('From'))[1]
      #信息判断
      result = judge(Subject, email_addr)
      print(result)
      #根据判断结果，执行操作
      if result == 1:
        pop_connect.dele(index)
        break
    # 登出email
    pop_connect.quit()
    return result 

  except Exception as e:
      print('login fail! ' + str(e))
      quit() 

def main():
  host = 'pop.sina.com'
  user = '********@sina.com'
  password = '********'
  while 1:
    result = Check_Subject(host, user, password)
    if result == 1:
      cmd = 'cmd /k shutdown -l'
      os.system(cmd)
      break
    time.sleep(60) # 两次检索邮件的时间间隔60s 

main()
