python2.7实现邮件发送功能

时间:2021-04-28 01:03     来源/作者:Lockeyi

要想实现一个能够发送带有文本、图片、附件的python程序,首先要熟悉两大模块:

email以及smtplib

然后对于MIME(邮件扩展)要有一定认知,因为有了扩展才能发送附件以及图片这些媒体或者非文本信息

最后一个比较细节的方法就是MIMEMultipart,要理解其用法以及对应参数所实现的功能区别

发送邮件三部曲:

创建协议对象
连接邮件服务器
登陆并发送邮件

  smtp.connect(smtp_server)
  smtp.sendmail(from_addr=self.from_addr, to_addrs=self.to_addr + self.cc_addr, msg=self.__to_mime_message().as_string())
  smtp.close()

对于实际发送程序,要注意个参数的类型,比如from_addr是字符串,to_addr和cc_addr以及attachment都是列表
