方法详细信息

solve(url, params, requestOptions){Promise<RouteSolveResult>}

使用路径参数求解针对路径图层的路径。

参数：

url String 表示网络分析服务的 GeoScene Server REST 资源的 URL。

params RouteParameters 用作输入以生成路径的路径参数。

requestOptions Object optional 用于数据请求的其他选项（将覆盖在构造期间定义的 requestOptions）。

返回：

类型	说明
Promise<RouteSolveResult>	解析后，返回 RouteSolveResult 的实例。

示例：

require([
  "geoscene/rest/route",
  "geoscene/core/Collection",
  "geoscene/rest/support/RouteParameters",
  "geoscene/rest/support/Stop",
  ...
], function(route, Collection, RouteParameters, Stop, ... ) {

  // point the URL to a valid routing service
  const routeUrl =
    "https://route-api.geoscene.cn/arcgis/rest/services/World/Route/NAServer/Route_World";

  // create a Collection of new Stops
  const stops = new Collection([
    new Stop({
      geometry: { x: -117.59275, y: 34.06200 },
      name: "Ontario Airport"
    }),
    new Stop({
      geometry: { x: -117.19570, y: 34.05609 },
      name: "Esri Campus"
    })
  ]);

  // setup the RouteParameters with API key and Stops
  const routeParams = new RouteParameters({
    // An authorization string used to access the routing service
    apiKey: "YOUR_API_KEY",
    stops
  });

  // solve the route with the RouteParameters
  function solveRoute() {
    route.solve(routeUrl, routeParams).then(showRouteInfo);
  }

  // do something useful with the results
  // like display them to the console
  function showRouteInfo(routeSolveResult) {
    console.log("Show all results: ", routeSolveResult);
    console.log("Show the route information: ", routeSolveResult.routeResults[0].route);
  }

  solveRoute();
});
