Python菜譜7：發(fā)送混合郵件

我們平時(shí)需要使用 Python 發(fā)送各類郵件，這個(gè)需求怎么來(lái)實(shí)現(xiàn)？答案其實(shí)很簡(jiǎn)單，smtplib 和 email庫(kù)可以幫忙實(shí)現(xiàn)這個(gè)需求。smtplib 和 email 的組合可以用來(lái)發(fā)送各類郵件：普通文本，HTML 形式，帶附件，群發(fā)郵件，帶圖片的郵件等等。我們這里將會(huì)分幾節(jié)把發(fā)送郵件功能解釋完成。

smtplib 是 Python 用來(lái)發(fā)送郵件的模塊，email 是用來(lái)處理郵件消息。

發(fā)送郵件系列最后一篇將會(huì)介紹發(fā)送混合郵件：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)
# 構(gòu)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：這里的代碼并沒(méi)有把異常處理加入，需要讀者自己處理異常。
