为什么Django发送电子邮件功能会发送两次电子邮件？

如何解决为什么Django发送电子邮件功能会发送两次电子邮件？

我已经使用了Django EmailMessage函数。
这是views.py文件。

def send_bill_mail(request):
    context_dict={
                "name": "abc"
                }
    html_message = render_to_string('home/email_templates/bill_generation.html',context_dict)
    try:
        email = EmailMessage(
            ' Welcome to store',html_message,to=['abc@gmail.com']
            )
        email.content_subtype = "html" 
        email.send()
    except Exception as e:
        messages.error(request,"Something Went Wrong !")
    return redirect('home:dashboard')

这里是settings.py

EMAIL_BACKEND = 'django.core.mail.backends.smtp.EmailBackend'
EMAIL_USE_TLS = True
EMAIL_HOST = 'smtp.gmail.com'
EMAIL_HOST_USER = 'xyz@gmail.com'
EMAIL_HOST_PASSWORD = 'xyz'
EMAIL_PORT = 587

在处理视图期间发生以下异常。

    Exception happened during processing of request from ('127.0.0.1',50522)
Traceback (most recent call last):

解决方法

当您在本地运行项目时，通常会发生此问题，也许您应该尝试将其托管在Internet上的某个地方

或

使用连接可以解决以下问题

  def send_bill_mail(request):
        context_dict={
                    "name": "abc"
                    }
        html_message = render_to_string('home/email_templates/bill_generation.html',context_dict)
        email_list = []
        try:
            email = EmailMessage(
                ' Welcome to store',html_message,to=['abc@gmail.com']
                )
            email.content_subtype = "html" 
            email_list.append(email)
            connection = mail.get_connection() 
            connection.send_messages(email_list)
        except Exception as e:
            messages.error(request,"Something Went Wrong !")
        return redirect('home:dashboard')
