Ошибка HTTP 401: неавторизованный SendGrid django

0 голосов
/ 09 апреля 2020

Я пытаюсь сделать почтовую подписку на своем django веб-сайте. Я следовал инструкциям в Интернете о том, как этого добиться. Я прошел через это тщательно, но всякий раз, когда я вхожу и пишу по электронной почте, появляется сообщение об ошибке HTTP 401: не авторизовано. Я перебрал инструкции и не смог найти, где ошибся.

Код настроек FROM_EMAIL = 'newsletter@example.com' # замените своим адресом SENDGRID_API_KEY = os.environ.get ('SENDGRID_API_KEY')

Код модели: 

class Subscriber(models.Model):
    email = models.EmailField(unique=True)
    conf_num = models.CharField(max_length=15)
    confirmed = models.BooleanField(default=False)

    def __str__(self):
        return self.email + " (" + ("not " if not self.confirmed else "") + "confirmed)"


class Newsletter(models.Model):
    created_at = models.DateTimeField(auto_now_add=True)
    updated_at = models.DateTimeField(auto_now=True)
    subject = models.CharField(max_length=150)
    contents = models.FileField(upload_to='uploaded_newsletters/')

    def __str__(self):
        return self.subject + " " + self.created_at.strftime("%B %d, %Y")

    def send(self, request):
        contents = self.contents.read().decode('utf-8')
        subscribers = Subscriber.objects.filter(confirmed=True)
        sg = SendGridAPIClient(settings.SENDGRID_API_KEY)
        for sub in subscribers:
            message = Mail(
                    from_email=settings.FROM_EMAIL,
                    to_emails=sub.email,
                    subject=self.subject,
                    html_content=contents + (

замените SENDGRID_API_KEY = os.environ.get ('SENDGRID_API_KEY') на SENDGRID_API_KEY = ('SENDGRID_API_KEY') и проверьте пользователей в sendgrid https://sendgrid.com/docs/ui/account-and-settings/how-to-set-up-domain-authentication/
