-
Copy the following into
~/your_projects/tutorial/app.py:from waitress import serve from pyramid.config import Configurator from pyramid.response import Response import pyramid_default_cors def hello_world(request): print('Incoming request') return Response('<body><h1>Hello World!</h1></body>') if __name__ == '__main__': with Configurator() as config: # This should be included before any other route definitions config.include('pyramid_default_cors') config.add_route('hello', '/') config.add_view(hello_world, route_name='hello') app = config.make_wsgi_app() serve(app, host='0.0.0.0', port=6543)
-
Run the application
# You can run this app using the local dev environment outlined above
python app.pyYour App should now be ready to handle CORS preflight requests via OPTIONS verb
curl -H "Origin: http://foobar.xyz" \
-H "Access-Control-Request-Method: POST" \
-H "Access-Control-Request-Headers: X-Requested-With" \
-X OPTIONS --verbose http://localhost:6543/
