python实现带附件的邮件发送基于smtp协议

#python实现发送邮件带附件
from email.mime.text import MIMEText
from email.mime.multipart import MIMEMultipart
import smtplib
#创建一个带附件的实例
msg = MIMEMultipart()
#构造附件1
file1 = MIMEText(open('E:\\桌面存储位置\\计算18-9班冯磊 实验2.zip','rb').read(), 'base64', 'utf-8')
file1["Content-Type"] = 'application/octet-stream'
file1["Content-Disposition"] = 'attachment; filename="a.zip"' #这里的filename可以任意写，写什么名字，邮件中显示什么名字
msg.attach(file1)
#加邮件头
msg['To'] = '***@qq.com'
msg['From'] = '**@qq.com'
msg['subject'] = 'python'
#发送邮件
server = smtplib.SMTP_SSL('pop.qq.com',465)
server.login('****@qq.com','*****')#XXX为用户名，XXXXX为密码
server.sendmail(msg['From'], msg['To'],msg.as_string())
server.quit()
