Python发送Email方法实例

本文以实例形式展示了Python发送Email功能的实现方法，有不错的实用价值的技巧，且功能较为完善。具体实现方法如下：

主要功能代码如下：

    #/usr/bin/env python
    # -*- encoding=utf-8 -*-

    import base64
    import smtplib
    from email.mime.multipart import MIMEMultipart
    from email.mime.text import MIMEText

    class CCSendMail:
      def __init__(self,host="your.mailhost.com",username='fromuser@xxx.com',password='passwd'):
        self.__smtp=smtplib.SMTP(host)
        self.__subject=None
        self.__content=None
        self.__from=None
        self.__to=[]
        self.__style='html'
        self.__charset='gb2312'
        self.username = username
        self.password = password
        self.fromAlias='fromuser' #发件人别名
        self.from2=''

      def close(self):
        try:
          self.__smtp.quit()
        except Exception ,e:
          pass  
      def setFromAlias(self,alias):
        self.fromAlias=alias
      def setStyle(self,style):
        self.__style = style
      def setFrom2(self,from2):
        self.from2=from2

      def setSubject(self,subject):
        self.__subject=subject

      def setContent(self,content):
        self.__content=content

      def setFrom(self,address):
        self.__from=address

      def addTo(self,address):
        self.__to.append(address)

      def setCharset(self,charset):
        self.__charset=charset

      def send(self):
        try:
          self.__smtp.set_debuglevel(1)

          #login if necessary
          if self.username and self.password:
            self.__smtp.login(self.username,self.password)

          msgRoot = MIMEMultipart('related')
          msgRoot['Subject'] = self.__subject
          aliasB6=base64.encodestring(self.fromAlias.encode(self.__charset))
          if len(self.from2)==0:
            msgRoot['From'] = "=?%s?B?%s?=%s"%(self.__charset,aliasB6.strip(),self.__from)
          else:
            msgRoot['From'] = "%s"%(self.from2)
          msgRoot['To'] = ";".join(self.__to)

          msgAlternative = MIMEMultipart('alternative')
          msgRoot.attach(msgAlternative)

          msgText = MIMEText(self.__content, self.__style,self.__charset)
          msgAlternative.attach(msgText)

          self.__smtp.sendmail(self.__from,self.__to,msgRoot.as_string())
          return True
        except Exception,e:
          print "Error ",e
          return False

      def clearRecipient(self):
        self.__to = []

      #给单个人发送邮件
      def sendHtml(self,address,title,content):
        self.setStyle('html')
        self.setFrom("<%s>"%self.username)
        if not isinstance(content,str):
          content = content.encode('gb18030')
        self.addTo(address)
        self.setSubject(title)
        self.setContent(content)
        ret = self.send()
        self.close()
        return ret

      #群发邮件
      def sendMoreHtml(self,addressList,title,content):
        self.setStyle('html')
        self.setFrom("<%s>"%self.username)
        if not isinstance(content,str):
          content = content.encode('gb18030')
        for address in addressList:
          self.addTo(address)
        self.setSubject(title)
        self.setContent(content)
        ret = self.send()
        self.close()
        return ret

    #测试
    def main():
      send=CCSendMail()
      send.sendHtml('touser@xxx.com',u'邮件标题',u'邮件内容')
      #send.sendMoreHtml([touser1@xx.com,touser2@xx.com],u'邮件标题',u'邮件内容')

    if __name__=='__main__':
      main()
