smtp发送邮件

使用python发送邮件的流程：

1、获得smtp服务

2、连接服务器

3、模拟客户端登录

4、实现邮件发送

5、退出登录

发送不带附件邮件

from email.mime.text import MIMEText

import smtplib

msg = MIMEText(‘hello,this is a mail...’,’plain’,’utf-8’)

参数：邮件正文、‘plain’表示纯文本、utf-8编码

msg[‘From’] = _formate_addr(‘发送者’)

msg[‘To’] = _format_addr(‘接收者’)

msg[‘Subject’] = ‘邮件主题’

server = smtplib.SMTP()

server.set_debuglevel(1)

server.connect(smtp_server,25)

server.login(发送者帐号，发送者密码)

server.sendmail(发送者帐号，接收地址，str(msg))

server.quit()

发送带附件邮件

import smtplib

from email.mime.text import MIMEText

from email.mime.multipart import

MIMEMultipart

from email.mime.application import

MIMEApplication

msg = MIMEMultipart()

msg[‘From’] = _formate_addr(‘发送者’)

msg[‘To’] = _format_addr(‘接收者’)

msg[‘Subject’] = ‘邮件主题’

#纯文本部分

msg.attach(MIMEText(‘hello,this is a mail...’,’plain’,’utf-8’)

#首先是xlsx类型的附件

xlsxpart =MIMEApplication(open('test.xlsx', 'rb').read())

xlsxpart.add_header('Content-Disposition','attachment', filename='test.xlsx')

msg.attach(xlsxpart)

# jpg类型的附件

jpgpart = MIMEApplication(open('beauty.jpg','rb').read())

jpgpart.add_header('Content-Disposition','attachment', filename='beauty.jpg')

msg.attach(jpgpart)

# mp3类型的附件

mp3part = MIMEApplication(open('kenny.mp3','rb').read())

mp3part.add_header('Content-Disposition','attachment', filename='benny.mp3')

msg.attach(mp3part)
