Pyhton发送邮件

Posted 2021-01-05

Python使用smtplib和email库发送邮件，发送html格式正文，插入图片，以及发送execl等文件。实例代码如下：

#/usr/bin/env python
#-*- coding:utf-8 -*-
#auther:yuanmuc
#email

import smtplib
from email.mime.multipart import MIMEMultipart
from email.mime.text import MIMEText
from email.mime.image import MIMEImage
from email.header import Header
from email.mime.application import MIMEApplication
import time

#收件人列表
mailto_list = [‘[email protected]‘,‘[email protected]‘]
#发件人用户名
mail_user = "monitor"
#邮件域后缀
mail_postfix = "localtest"

def Send_Mail(to_list,sendinfo):
    #邮件标题
    title = "网络质量告警" + time.strftime(‘%Y%m%d‘,time.localtime(time.time()))
    #增加图片附件
    def addimg(src,imgid):
        fd = open(src,‘rb‘)
        msgImage = MIMEImage(fd.read())
        fd.close()
        msgImage.add_header("Content-ID",imgid)
        return msgImage
    #发送execl附件
    def attachexecl(f):
        part = MIMEApplication(open(f,‘rb‘).read())
        part.add_header("Content-Disposition",‘attachment‘,filename=f)
        msg.attach(part)

        msg = MIMEMultipart(‘related‘)
        #html邮件正文
        msgtext = MIMEText(sendinfo,"html","utf-8")
        msg.attach(msgtext)
        #添加图片,imgid是html中的图片id
        imgfile = "a.png"
        imgid = "hello"
        msg.attach(addimg(imgfile,imgid))
        #添加execl附件
        execlfile = "test.xlsx"
        attachexecl(execlfile)

        #连接邮件服务器
        me = mail_user + "@" + mail_postfix
        msg["Subject"] = title
        msg["From"] = me
        msg["To"] = ";".join(to_list)
        send_to = to_list
        try:
                server = smtplib.SMTP("192.168.1.192")
                server.set_debuglevel(1)
                server.sendmail(me,send_to,msg.as_string())
                return True
        except Exception e:
                print str(e)

def Main(sendinfo):
      if Send_Mail(mailto_list,sendinfo):
           print "发送成功"
      else:
           print "发送失败"

if __name__ == ‘__main__‘:
    sendhtml = "<h1>这是一个测试</h1><img src="cid:hello" width=‘650‘ height=‘220‘/>"
    Main(sendhtml)
