用法說明

例子：

// Routing with the RouteLayer's default route service requires an apikey.
const apiKey = "<your api key>";

// A minimum of two stops is required for routing.
const stops = [
  new Stop({ geometry: { x: -117.1825, y: 34.054722 }}),
  new Stop({ geometry: { x: -116.545278, y: 33.830278 }})
];

// Create route layer and assign the stops. Only solved routelayers will be rendered.
const routeLayer = new RouteLayer({
  stops
});

// Create a view and add the routelayer to the view's map.
const view = new MapView({
  container: "viewDiv",
  map: new Map({
    basemap: "dark-gray-vector",
    layers: [ routeLayer ]
  })
});

// Wait for the view to load since we'll be zooming to the extent of the zoomed solution.
view.when().then(async () => {
  // Solve the route using routelayer stops and barries and additional properties from the parsed RouteParameters
  // object. Use the RouteParameters to provide the apiKey and other setting like directions language and travel
  // mode.
  const results = await routeLayer.solve({ apiKey });

  // Use the returned result to update the RouteLayer. This method will overwrite the stops, barriers, directions and
  // routeInfo properties.
  routeLayer.update(results);

  // Zoom to the extent of the solve route.
  view.goTo(routeLayer.routeInfo.geometry);
});
