Question

我正在使用Python email.mime lib来编写电子邮件，我创建了两个MIMEText对象，然后将它们作为文本（而不是附件）附加到Message上，结果我得到了如下的MIME文档，就像你一样可以看到有两个文本对象，一个是plain类型，另一个是html类型，我的问题是我只能看到一些邮件客户端中的后一个文本对象（这里是html），而我可以看到两个文本某些其他邮件客户端中的对象（例如，live.com），是什么导致了这个？

Content-Type: multipart/mixed; boundary="===============0542266593=="
MIME-Version: 1.0
FROM: john.smith@NYU.com
TO: john.smith@live.com, john.smith@gmail.com

您已将'multipart / mixed'指定为mime类型。如果您只想显示一个项目，请指定“multipart / alternative”，如下所示：

email.mime.multipart import MIMEMultipart
from email.mime.text import MIMEText
from email.encoders import encode_base64

# Note: 'alternative' means only display one of the items. 
msg = MIMEMultipart('alternative')
msg['Subject'] = "Hello"
msg['From'] = 'me@example.com'
msg['To'] = 'you@example.com'

msg.attach(MIMEText('Hello!', 'plain'))
msg.attach(MIMEText('<b>Hello!</b>', 'html'))

# Not required, but you had it in your example, so I kept it.
for i in msg.get_payload():
    encode_base64(i)

print msg.as_string()

并非所有MIME文本都显示在邮件服务器上
