Question

我试图创建一个使用send_mass_email发送HTML电子邮件回复的联系表单，但我一直收到语法错误。

我在views.py中有以下代码

def email(request, template='marketing/email.html'):
    form = ContactForm(request.POST or None)
    if form.is_valid():
        subject = form.cleaned_data['subject']
        from_email = form.cleaned_data['from_email']
        message = form.cleaned_data['message']
        html_content = render_to_string(
            'marketing/welcome.html',
            {
                'message': message,
                'subject': subject,

            }
        )
        try:
            message1 = (subject, message, from_email, ['test@test.com'], html_message=html_content)
            message2 = (subject, message, from_email, ['test@test.com'], html_message=html_content)
            send_mass_mail((message1, message2), fail_silently=False)
        except BadHeaderError:
            return HttpResponse('Invalid header found.')
        return redirect('thanks')
    context = {
            "form": form,

        }
    return render(request, template, context)

def thanks(request):
    return HttpResponse('Thank you for your message.')

我一直收到以下错误。

    message1 = (subject, message, from_email, ['test@test.com'], html_message=html_content)
SyntaxError: invalid syntax

Answer 1

发送电子邮件的良好做法是附加HTML和纯文本版本：

msg = EmailMultiAlternatives(subject, message_plaintext, from_email, recipient_list)
msg.attach_alternative(message_html, "text/html")

然后，给定一堆EmailMultiAlternatives个实例，您可以通过connection.send_messages(messages)批量发送所有这些实例 - 请参阅this answer。

这是最终的工作版本。
