The problem is when sending a post request from the client to the django server. Both the client and the server are deployed locally. I've double-checked where the problem might be many times, so I'm attaching the code from the views and settings file. javascript code fetch('http://127.0.0.1:8000/products/', { method: 'POST', headers: { 'Content-Type': 'application/json' }, body: JSON.stringify(userData) }) .then(response => response.json()) .then(data => console.log(data.basket)) .catch(error => console.error('Basket get error', error)); python code views: @csrf_exempt def get_all_products(request): if request.method == 'POST': try: data = json.loads(request.body) print(data) except Exception as e: return JsonResponse({'error': str(e)}, status=400) return JsonResponse({'error': 'Invalid request method'}, status=405) settings: ALLOWED_HOSTS = ['localhost', '127.0.0.1'] # Application definition INSTALLED_APPS = [ 'django.contrib.admin', 'django.contrib.auth', 'django.contrib.contenttypes', 'django.contrib.sessions', 'django.contrib.messages', 'django.contrib.staticfiles', 'mini_app', 'corsheaders' ] MIDDLEWARE = [ 'django.middleware.security.SecurityMiddleware', 'django.contrib.sessions.middleware.SessionMiddleware', 'django.middleware.common.CommonMiddleware', 'django.middleware.csrf.CsrfViewMiddleware', 'django.contrib.auth.middleware.AuthenticationMiddleware', 'django.contrib.messages.middleware.MessageMiddleware', 'django.middleware.clickjacking.XFrameOptionsMiddleware', 'corsheaders.middleware.CorsMiddleware', 'django.middleware.common.CommonMiddleware', ] CORS_ALLOW_METHODS = [ 'DELETE', 'GET', 'OPTIONS', 'PATCH', 'POST', 'PUT', 'DELETE' ] CORS_ALLOWED_ORIGINS = [ 'http://127.0.0.1:5500', 'http://localhost:5500' ] output in the python django console: Method Not Allowed: /products/ [05/Apr/2025 13:05:54] "POST /products/ HTTP/1.1" 405 35 output in the browser console POST http://127.0.0.1:8000/products/ 405 (Method Not Allowed) Continue reading...
