Django / Python POST API without Model/Serializer

I want to create a very simple API, with only one endpoint. I want to send to an API a json like : {"provider" : "com.facebook.orca", "code" : "1", "color" : "#FFFFF" }

Then, I want to use a python library to control a device in my room(python-yeelight). I want to use this with a Auth token or a username/password authenticate.

What I found on Django Rest Framework was way too complicated for what I need(which is accepting a POST and returning a "success" or "failure" message.

Thank you!

You can create a method decorator to implement basic authentication. Wrap all your django views using this decorator. 

def token_required(function):
    def wrap(request, *args, **kwargs):
        auth_token = request.META.get('HTTP_AUTHORIZATION_TOKEN')
        if auth_token:
            try:
                token = Tokens.objects.get(token=auth_token)
                user = token.user
            except Tokens.DoesNotExist:
                user=None
        else:
            r = {
                    'status': -1,
                    'message': 'Please provide a valid token.'
                }
            return HttpResponse(json.dumps(r), content_type="application/json")
        if user:
            request.user = user
            return function(request, *args, **kwargs)
        else:
            r = {
                        'status': -2,
                        'message': 'User not Authorised, Please login'
                }
            return HttpResponse(json.dumps(r), content_type="application/json")
    return wrap

Now all your requests must contain a header as shown below to views wrapped by this decorator to detect the user inside views.

AUTHORIZATION-TOKEN : some_token_value

Your tokens model will look something like as shown below.

class Tokens(models.Model):
    user = models.OneToOneField(User, related_name="tokens",null=False)
    token = models.CharField(max_length=255, unique=True)

    def save(self, *args, **kwargs):
        if self.token is None or self.token == "":
            import uuid
            self.token=uuid.uuid4().hex
        super(Tokens, self).save(*args, **kwargs)

Sample use of decorator:

@csrf_exempt
@token_required
def your_view(request):
    pass

I guess this should help you out.
