【中文标题】在 Python3 中使用 smtplib 发送多部分电子邮件,但未显示第二部分【英文标题】:Sending multi-part email using smtplib in Python3 but second part not displayed 【发布时间】:2018-11-28 03:07:32 【问题描述】:我正在使用以下演示代码在 Python3 中发送多部分 html 电子邮件。但奇怪的是,第一部分,即纯文本,并没有显示在收到的电子邮件中,而只显示第二部分,即 html 内容。任何人都可以帮忙吗?谢谢!
#!/usr/bin/env python
import smtplib
from email.mime.multipart import MIMEMultipart
from email.mime.text import MIMEText
# me == my email address
# you == recipient's email address
me = "my@email.com"
you = "your@email.com"
# Create message container - the correct MIME type is multipart/alternative.
msg = MIMEMultipart('alternative')
msg['Subject'] = "Link"
msg['From'] = me
msg['To'] = you
# Create the body of the message (a plain-text and an HTML version).
text = "Hi!\nHow are you?\nHere is the link you wanted:\nhttps://www.python.org"
html = """\
<html>
<head></head>
<body>
<p>Hi!<br>
How are you?<br>
Here is the <a href="https://www.python.org">link</a> you wanted.
</p>
</body>
</html>
"""
# 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)
# Send the message via local SMTP server.
s = smtplib.SMTP('localhost')
# sendmail function takes 3 arguments: sender's address, recipient's address
# and message to send - here it is sent as one string.
s.sendmail(me, you, msg.as_string())
s.quit()
【问题讨论】:
【参考方案1】:您已将Content-Type:
声明为multipart/alternative
。
电子邮件阅读器将决定显示哪个替代版本。
Mail multipart/alternative vs multipart/mixed
