Python菜谱7:发送混合邮件

由 Little_Mo 创建,平台活动 最后一次修改 2016-02-24

我们平时需要使用 Python 发送各类邮件,这个需求怎么来实现?答案其实很简单,smtplib 和 email库可以帮忙实现这个需求。smtplib 和 email 的组合可以用来发送各类邮件:普通文本,HTML 形式,带附件,群发邮件,带图片的邮件等等。我们这里将会分几节把发送邮件功能解释完成。

smtplib 是 Python 用来发送邮件的模块,email 是用来处理邮件消息。

发送邮件系列最后一篇将会介绍发送混合邮件:里面包含附件,HTML 形式,不同文本:

import smtplib
from email.mime.multipart import MIMEMultipart
from email.mime.text import MIMEText

sender = '***'
receiver = '***'
subject = 'python email test'
smtpserver = 'smtp.163.com'
username = '***'
password = '***'

# Create message container - the correct MIME type is multipart/alternative.
msg = MIMEMultipart('mixed')
msg['Subject'] = "Link"

# Create the body of the message (a plain-text and an HTML version).
text = "Hi!\nHow are you?\nHere is the link you wanted:\nhttp://www.python.org"
html = """\

Hi!

 How are you?

 Here is the link you wanted.

"""

# Record the MIME types of both parts - text/plain and text/html.
part1 = MIMEText(text, 'plain')
part2 = MIMEText(html, 'html')

# Attach parts into message container.
# According to RFC 2046, the last part of a multipart message, in this case
# the HTML message, is best and preferred.
msg.attach(part1)
msg.attach(part2)
# 构造附件
att = MIMEText(open('/Users/1.jpg', 'rb').read(), 'base64', 'utf-8')
att["Content-Type"] = 'application/octet-stream'
att["Content-Disposition"] = 'attachment; filename="1.jpg"'
msg.attach(att)

smtp = smtplib.SMTP()
smtp.connect(smtpserver)
smtp.login(username, password)
smtp.sendmail(sender, receiver, msg.as_string())
smtp.quit()

注意:这里的代码并没有把异常处理加入,需要读者自己处理异常。
