We must make the necessary resource routing configurations to call the appropriate methods and pass them all the necessary arguments by defining URL rules. The following lines create the main entry point for the application, initialize it with a Flask application and configure the resource routing for the api. Open the previously created api/api.py file and add the following lines. The code file for the sample is included in the restful_python_chapter_05_01 folder:
app = Flask(__name__)
api = Api(app)
api.add_resource(MessageList, '/api/messages/')
api.add_resource(Message, '/api/messages/<int:id>', endpoint='message_endpoint')
if __name__ == '__main__':
app.run(debug=True)
The code creates an instance of the flask_restful.Api class and saves it in the api variable. Each call to the api.add_resource method routes a URL to a resource, specifically to one of the previously declared subclasses of the flask_restful.Resource class...
