Route Via Intermediate Waypoint - 通过参数传递坐标列表

Question

我需要通过参数在中传递参数内的坐标列表，但我找不到方法。这是一个只有一对坐标（纬度，经度）的例子：

function calculateRoute (platform) { var router = platform.getRoutingService(null, 8), routeRequestParams = { routingMode: 'fast', transportMode: 'truck', origin: '36.87689,-2.44138', destination: '36.69630,-4.47968', via: '38.99112,-1.86902', //LIST HERE!!! return: 'polyline' }; router.calculateRoute( routeRequestParams, onSuccessRoute, onError ); }

我希望得到的url是这样的：

https://router.hereapi.com/v8/routes?apikey= {API_KEY}&routingMode=fast&transportMode=truck&origin=36.87689,-2.44138&via=38.99112,-1.86902&via=37.95862,-1.15538&destination=36.69630,-4.47968&return=polyline

如您所见，via 在 URL 中重复。

非常感谢！

不知道对你有没有帮助，但是

function calculateRouteFromAtoB (platform) {
  var router = platform.getRoutingService(),
      routeRequestParams = {
      mode: 'fastest;car',
      representation: 'display',
      routeattributes : 'waypoints,summary,shape,legs',
      maneuverattributes: 'direction,action',
      waypoint0: '55.7520,37.6175',
      waypoint1: '55.8941,37.4439',
      waypoint2: '55.7982,37.9680'
      };
  router.calculateRoute(
      routeRequestParams,
      onSuccess,
      onError
  );
}

适合我。

关于 Routing v8 API，JavaScript API（还）不支持多路由 waypoints，也就是说，它不支持传递列表via 参数的坐标。

所以最好的办法是直接以 Routing v8 REST API 为目标，就像关注一样，并从响应中构建折线：

# Note: line breaks and spaces are for readability only (they need to be removed)

https://router.hereapi.com/v8/routes?
  origin=52.550464,13.384223
  &transportMode=car
  &destination=52.477545,13.447395
  &via=52.529791,13.401389
  &via=52.513079,13.424392
  &via=52.487581,13.425079
  &apikey={YOUR_API_KEY}
