Python发送邮件，body是html（纯文本）的，收到后怎么变成了源码格式了？

Question

file = "AbstractCachingViewResolver.html"
content = open(file).read()
body = content
send_mail(mail, subject, body)
应该怎么解决？

Answer 1

from email.mime.text import MIMEText
...
body = MIMEText(content,_subtype='html',_charset='utf8')
...
send_mail(mail, subject, body.as_string())
