Python 发送带附件的邮件

发送带附件的邮件，首先要创建MIMEMultipart()实例，然后构造附件，如果有多个附件，可依次构造，最后利用smtplib.smtp发送。

实例

#!/usr/bin/python3

import smtplib

from email.mime.text import MIMEText

from email.mime.multipart import MIMEMultipart

from email.header import Header

sender = 'from@runoob.com'

receivers = ['429240967@qq.com']  # 接收邮件，可设置为你的QQ邮箱或者其他邮箱

#创建一个带附件的实例

message = MIMEMultipart()

message['From'] = Header("菜鸟教程", 'utf-8')

message['To'] =  Header("测试", 'utf-8')

subject = 'Python SMTP 邮件测试'

message['Subject'] = Header(subject, 'utf-8')

#邮件正文内容

message.attach(MIMEText('这是菜鸟教程Python 邮件发送测试……', 'plain', 'utf-8'))

# 构造附件1，传送当前目录下的 test.txt 文件

att1 = MIMEText(open('test.txt', 'rb').read(), 'base64', 'utf-8')

att1["Content-Type"] = 'application/octet-stream'

# 这里的filename可以任意写，写什么名字，邮件中显示什么名字

att1["Content-Disposition"] = 'attachment; filename="test.txt"'

message.attach(att1)

# 构造附件2，传送当前目录下的 runoob.txt 文件

att2 = MIMEText(open('runoob.txt', 'rb').read(), 'base64', 'utf-8')

att2["Content-Type"] = 'application/octet-stream'

att2["Content-Disposition"] = 'attachment; filename="runoob.txt"'

message.attach(att2)

try:

   smtpObj = smtplib.SMTP('localhost')

   smtpObj.sendmail(sender, receivers, message.as_string())

   print ("邮件发送成功")

except smtplib.SMTPException:

   print ("Error: 无法发送邮件")

$ python3 test.py  

邮件发送成功
