Question

我试图用Django，sendmail发送电子邮件，但出于某种原因，它抛出了这个错误，并显示问题是我的电子邮件，即这条['abrarshahriar360@gmail.com'],行。它在开发服务器上运行良好，在我使用heroku部署它之后，一切都很好，就在我试图发送电子邮件时，它显示了这一点。我的双因素身份验证使关闭了，而安全性较低的应用程序使关闭了。为什么这个错误是SHown呢？提前感谢！

我的views.py：

def appointment(request):
    if request.method == "POST":
        your_name = request.POST['your-name']
        your_phone = request.POST['your-phone']
        your_email = request.POST['your-email']
        your_address = request.POST['your-address']
        your_schedule = request.POST['your-schedule']
        your_date = request.POST['your-date']
        your_message = request.POST['your-message']

        appointment = "Name: " + your_name + "  " + "Phone: " + your_phone + "  " + "Email: " + your_email + "  " + "Address: " + your_address + "  " + "Schedule: " + your_schedule + "  " + "Appointment Date: " + your_date + "  " + "Message: " + your_message 

        send_mail(
            'Appointment request form ' + your_name,
            appointment,
            your_email,
            ['abrarshahriar360@gmail.com'],
            )

        return render(request, 'appointment.html', {
            'your_name' : your_name,
            'your_phone' : your_phone,
            'your_email' : your_email,
            'your_address' : your_address,
            'your_schedule' : your_schedule,
            'your_date' : your_date,
            'your_message' : your_message
            })
    else:
        return render(request, 'home.html', {})

我的settings.py：

STATICFILES_STORAGE = 'whitenoise.storage.CompressedManifestStaticFilesStorage'

# Email Settings

EMAIL_HOST = 'smtp.gmail.com'
EMAIL_PORT = 587
EMAIL_HOST_USER = 'abrarshahriar360@gmail.com'
EMAIL_HOST_PASSWORD = os.environ.get('Email_PASS')
EMAIL_USE_TLS = True


django_heroku.settings(locals())

Answer 1

其实是我的问题。我传递了错误的上下文变量。所以它抛出了那个错误
