如何集成Django的oAuth后端和google assistant的webhook意图？

django-admin startproject myproject
cd myproject
django-admin startapp myapp

pip install django-oauth-toolkit

INSTALLED_APPS = [
    ...
    'oauth2_provider',
    'myapp',
]

MIDDLEWARE = [
    ...
    'oauth2_provider.middleware.OAuth2TokenMiddleware',
]

OAUTH2_PROVIDER = {
    'SCOPES': {'read': 'Read scope', 'write': 'Write scope'},
}

from django.http import JsonResponse
from django.views.decorators.csrf import csrf_exempt
import json

@csrf_exempt
def webhook(request):
    if request.method == 'POST':
        data = json.loads(request.body)
        intent = data['queryResult']['intent']['displayName']
        
        if intent == 'HelloIntent':
            response_text = 'Hello, how can I help you?'
        else:
            response_text = 'Sorry, I did not understand that.'
        
        return JsonResponse({
            'fulfillmentText': response_text,
            'source': 'webhookdata'
        })
    else:
        return JsonResponse({'error': 'Invalid request'}, status=400)

from django.urls import path
from .views import webhook

urlpatterns = [
    path('webhook/', webhook, name='webhook'),
]

from django.contrib import admin
from django.urls import path, include

urlpatterns = [
    path('admin/', admin.site.urls),
    path('o/', include('oauth2_provider.urls', namespace='oauth2_provider')),
    path('', include('myapp.urls')),
]

python manage.py runserver
