与 send_mail：

Answer 1

由于错误是由 built-in smtp python 库引发的，这意味着您传递了错误的编码类型。根据文档和错误消息，它需要二进制，但如果收到字符串，它会尝试转换为 ASCII。

似乎在某个地方你传递了一个 int ，而不是追逐编码，因为你没有使用 EmailMessage 的任何高级功能，你应该能够只使用实用程序Django提供的方法send_email

所以，这应该做到了

    mail.send_mail(subject = email_subject, message = message, 
                   from_email = settings.EMAIL_HOST_USER, [email_to], 
                   html_message=html_message)

应该不需要编码，您可以像往常一样在模板中使用上下文值，然后通过条带化生成 text/plain 消息 HTML 与 strip_tags ，即 message = strip_tags(html_message)
