我收到带有 html 附件的电子邮件。我希望我的电子邮件包含 html 和纯文本，均不带任何附件
# Create the MIME multipart message
msg = MIMEMultipart("mixed")
plain_text = "This is the plain text version of the email."
plain_part = MIMEText(plain_text, 'plain')
msg.attach(plain_part)
html_text = """
<html>
<head></head>
<body>
<p>This is the <b>HTML</b> version of the email.</p>
</body>
</html>
"""
html_part = MIMEText(html_text, 'html')
msg.attach(html_part)
msg['From'] = sender_email
msg['To'] = receiver_email
msg['Subject'] = "subject"
with smtplib.SMTP(smtp_server, smtp_port) as server:
server.starttls()
server.login(smtp_username, smtp_password)
server.sendmail(sender_email, receive`your text`r_email, msg.as_string())
所做的更改： 将 MIMEMultipart("mixed") 更改为 MIMEMultipart("alternative")，因为您想要提供内容的替代版本（纯文本和 HTML），而不是混合它们。 从 server.sendmail() 调用中删除了不必要的反引号。 此更正后的代码应发送一封包含 HTML 和纯文本内容且不带任何附件的电子邮件。只需确保将占位符值替换为您的实际电子邮件发送配置即可。
