我对 Here Maps Routing API v8 非常陌生。
我已经尝试过这里提供的示例:https://developer.here.com/documentation/maps/3.1.15.1/dev_guide/topics/routing.html https://developer.here.com/documentation/maps/3.1.15.1/dev_guide/topics/routing.html
我使用的路由参数如下所示:
var routingParameters = {
'routingMode': 'fast',
'transportMode': 'car',
'origin': '50.1120,8.6834',
'destination': '52.5309,13.3846',
'return': 'polyline'
};
现在我想在路由参数中添加多个航路点,并且我尝试了以下格式:
'via' : ['50.1234,8.7654', '51.2234,9.1123']
但是当我在路由参数中使用上述行时,请求失败。
您能否建议具有多个航点的请求的正确格式?
检查您正在使用的 HERE Maps JS API 的版本。从版本 3.1.19.0 开始支持此功能。
因此,计算具有多个航点的路线的方法是:
// departure point (origin)
var start = '52.550464,13.384223';
// collection of waypoints
var waypoints = [
'52.529791,13.401389'
'52.513079,13.424392'
'52.487581,13.425079'
];
// end point (destination)
var end = '52.477545,13.447395'
// routing parameters
var routingParameters = {
'origin': start,
'destination': end,
'via': new H.service.Url.MultiValueQueryParameter( waypoints ),
'routingMode': 'fast',
'transportMode': 'car',
'return': 'polyline'
};
// Get an instance of the routing service version 8:
var router = platform.getRoutingService(null, 8);
// Call `calculateRoute` with the routing parameters,
// the success callback and an error callback function
// The implementation of the two callback functions is left out for brevity
// see documentation link below for callback examples
router.calculateRoute(routingParameters, onResultCallback, onErrorCallback)
