Event
Description
When the flight request is completed
After data of the flying routes layer is returned by the API and processed by filters, this event is triggered to pass JSON-format data. For more information about specific data examples, see the Data Response Result section of the Data Source tab in the right-side configuration panel of the canvas editor.
Action
Action
Description
Request Flight
This action is performed to request the server data again. The data sent by an upstream data processing node or layer node is used as a parameter. For example, in the arc layer, the API data source is set to
https://api.test, and the data sent to the action of requesting a flying line is set to{ id: '1'}. In this case, the final request interface ishttps://api.test?id=1.Import flying lines
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 Source tab in the right-side configuration panel of the canvas editor.
