今天来分享一个“高大上”的技术——使用python编写一个可以用微信远程控制电脑的程序！

先来分析一下控制的具体流程：

我们使用微信给特定的邮箱发送一封邮件，其中包含了我们想要电脑执行的命令，然后电脑上的python程序获取到这封邮件，然后解析其中的命令，再交付给电脑执行。可以看出，这其中主要的技术难点就是获取邮件了！但是！这没有任何问题，大家看到我的上一篇博客《python 收发邮件》就可以了！

下面给出使用python收发邮件并执行邮件命令的代码。

# -*- coding:utf-8 -*- 
from email.mime.text import MIMEText 
import poplib 
import smtplib 
import os 
 
 
class MailManager(object): 
 
  def __init__(self): 
    self.popHost = 'pop.sina.com' 
    self.smtpHost = 'smtp.sina.com' 
    self.port = 25 
    self.userName = 'ivanzgj@sina.com' 
    self.passWord = 'zgj123' 
    self.bossMail = '475176416@qq.com' 
    self.login() 
    self.configMailBox() 
 
  # 登录邮箱 
  def login(self): 
    try: 
      self.mailLink = poplib.POP3_SSL(self.popHost) 
      self.mailLink.set_debuglevel(0) 
      self.mailLink.user(self.userName) 
      self.mailLink.pass_(self.passWord) 
      self.mailLink.list() 
      print u'login success!' 
    except Exception as e: 
      print u'login fail! ' + str(e) 
      quit() 
 
  # 获取邮件 
  def retrMail(self): 
    try: 
      mail_list = self.mailLink.list()[1] 
      if len(mail_list) == 0: 
        return None 
      mail_info = mail_list[0].split(' ') 
      number = mail_info[0] 
      mail = self.mailLink.retr(number)[1] 
      self.mailLink.dele(number) 
 
      subject = u'' 
      sender = u'' 
      for i in range(0, len(mail)): 
        if mail[i].startswith('Subject'): 
          subject = mail[i][9:] 
        if mail[i].startswith('X-Sender'): 
          sender = mail[i][10:] 
      content = {'subject': subject, 'sender': sender} 
      return content 
    except Exception as e: 
      print str(e) 
      return None 
 
  def configMailBox(self): 
    try: 
      self.mail_box = smtplib.SMTP(self.smtpHost, self.port) 
      self.mail_box.login(self.userName, self.passWord) 
      print u'config mailbox success!' 
    except Exception as e: 
      print u'config mailbox fail! ' + str(e) 
      quit() 
 
  # 发送邮件 
  def sendMsg(self, mail_body='Success!'): 
    try: 
      msg = MIMEText(mail_body, 'plain', 'utf-8') 
      msg['Subject'] = mail_body 
      msg['from'] = self.userName 
      self.mail_box.sendmail(self.userName, self.bossMail, msg.as_string()) 
      print u'send mail success!' 
    except Exception as e: 
      print u'send mail fail! ' + str(e) 
 
if __name__ == '__main__': 
  mailManager = MailManager() 
  mail = mailManager.retrMail() 
  if mail is not None: 
    cmd = mail['subject'] 
    os.system(cmd) 
    mailManager.sendMsg() 

上述代码的逻辑是：邮件的主题为要执行的命令，然后python获取邮箱的邮件，解析其主题，然后交到命令行执行。执行成功后发送一封success的邮件给我。

下面测试一下。我使用qq邮箱给我指定的邮箱发送了下面这样一封邮件。
