For example, if the API data source is https://api.test and the data passed to the Request Mapping Data action is { id: '1'}, the final request interface is https://api.test?id=1.
     Import mapping data	After data of a widget is processed in accordance with its drawing format, the widget is imported for redrawing. You do not need to request server data again. For more information about specific data examples, see the Data Response Result section of the Data tab in the right-side configuration panel of the canvas editor.
