Request scheduling When the program receives a request from the client, the view function to process the request is found. To complete this task, flask finds the requested URL in the URL map of the program. A URL mapping is a correspondence between a URL and a view function. Flask generates mappings using the App.route adorner or the App.add_url_rule () in the form of a non adorner. You can use App.url_map
