问题描述

我无法在 python 中发送带有正文的电子邮件作为多部分电子邮件.我所做的一切都导致所有内容都作为附件，我无法让文本或 html 显示在正文中.

I can't send an e-mail in python with a body as a multipart email. Everything I've tried has resulted in all of the content as attachments, and I can't get the text or html to show up in the body.

msg = MIMEMultipart()
if msg_mime_type == 'text' or not msg_mime_type:
    new_body = MIMEText(body, 'text')
elif msg_mime_type == 'image':
    new_body = MIMEImage(body)
elif msg_mime_type == 'html':
    new_body = MIMEText(body, 'html')
new_body.add_header('Content-Disposition', 'inline', filename='body')
msg.set_payload(new_body) #also tried msg.attach(new_body)

我需要使用 Multipart 以便我还可以添加附件，但为了简单起见，我保留了该代码.

I need to use a Multipart so that i can also add attachments, but I kept that code out for simplicity.

解决方案

您需要指定零件是彼此的替代品，例如multipart/alternative mime 类型:

You need to specify that the parts are alternatives of one another, e.g. the multipart/alternative mime type:

msg = MIMEMultipart('alternative')

默认为混合；请参阅电子邮件库示例.

请注意，要创建包含附件和替代 (HTML/CSS) 选项的电子邮件，您需要有一个包含 alternative<的顶级 multipart/related 容器/code> 部分作为第一个条目.

Note that to create an email with both attachments and an alternative (HTML / CSS) option you'll need to have a top-level multipart/related container that contains the alternative parts as the first entry.
