Question

我正在为Django REST API设置注册过程。我在SignUpView中使用“ email.send（）”功能。当我创建新用户时，它应该向他发送激活链接。不幸的是，我收到“ OSError：[Errno 99]无法分配请求的地址”。

我一直在寻找一些解决方案，但是所有解决方案都仅限于套接字的一些问题。尽管如此，我还是尝试在设置中更改端口。

settings.py中的我的电子邮件设置：

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

我曾经注册过的视图：

class SignUp(APIView):

    def post(self, request, format=None):
        serializer = SignUpSerializer(data=request.data)
        if serializer.is_valid():
            user = serializer.save(is_active=False)
            current_site = get_current_site(request)
            mail_subject = 'Aktywuj swoje konto w serwisie Podwoozka.'
            message =  'user: ', user.username,'domain', current_site.domain,'uid',urlsafe_base64_encode(force_bytes(user.pk)).decode(),'token', account_activation_token.make_token(user), 
            to_email = user.email
            email = EmailMessage(
                mail_subject, message, to=[to_email]
            )
            email.send()
            return HttpResponse('Potwierdz email aby zakonczyc rejestracje.')
        return Response(serializer.errors, status=status.HTTP_400_BAD_REQUEST)

最后，当我使用此功能时，整个回溯：

我不知道它是否重要，但是我在这个项目中使用了docker。我听说有时容器的传出连接存在一些问题。

编辑：我试图在pipenv而不是docker中运行它，仍然无法正常工作。这次是“ ConnectionRefusedError：[WinError 10061]无法建立连接，因为目标计算机主动拒绝了它”
