python smtplib模块实现发送邮件带附件sendmail

本文实例为大家分享了python smtplib实现发送邮件的具体代码，供大家参考，具体内容如下

#!/usr/bin/env python
# -*- coding: UTF-8 -*-

from email.mime.multipart import MIMEMultipart
from email.mime.base import MIMEBase
from email.mime.text import MIMEText

from email.utils import COMMASPACE,formatdate
from email import encoders

import os

def send_mail(server, fro, to, subject, text, files=[]):
  assert type(server) == dict
  assert type(to) == list
  assert type(files) == list

  msg = MIMEMultipart()
  msg['From'] = fro
  msg['Subject'] = subject
  msg['To'] = COMMASPACE.join(to) #COMMASPACE==', '
  msg['Date'] = formatdate(localtime=True)
  msg.attach(MIMEText(text))

  for f in files:
    part = MIMEBase('application', 'octet-stream') #'octet-stream': binary data
    part.set_payload(open(f, 'rb').read())
    encoders.encode_base64(part)
    part.add_header('Content-Disposition', 'attachment; filename="%s"' % os.path.basename(f))
    msg.attach(part)

  import smtplib
  smtp = smtplib.SMTP(server['name'], server['port'])
  smtp.ehlo()
  smtp.starttls()
  smtp.ehlo()
  smtp.login(server['user'], server['passwd'])
  smtp.sendmail(fro, to, msg.as_string())
  smtp.close()

if __name__=='__main__':
  server = {'name':'mail.server.com', 'user':'chenxiaowu', 'passwd':'xxxx', 'port':25}
  fro = '[e-mail]'
  to = ['[e-mail]']
  subject = '脚本运行提醒'
  text = 'mail content'
  files = ['top_category.txt']
  send_mail(server, fro, to, subject, text, files=files)

从网上找了些资料，不会有个别错误，上面代码经调试测试通过。
