Question

我使用api v3.1，正在尝试计算2个点之间的距离

这就是我所拥有的

<script src="https://js.api.here.com/v3/3.1/mapsjs-core.js"
            type="text/javascript" charset="utf-8"></script>
<script src="https://js.api.here.com/v3/3.1/mapsjs-service.js"
            type="text/javascript" charset="utf-8"></script>

var platform = new H.service.Platform({
        'apikey': 'key'
      })
 const params = {
            mode: 'car;',
            waypoint0: lat1 + ',' + lon1,
            waypoint1: lat2 + ',' + lon2,
            representation: 'display',
            routeAttributes: 'summary'
          }

var routingService = platform.getRoutingService()
          routingService.calculateRoute(params, success => {
            console.log(success.response.route[0].summary)
          }, error => {
            console.log(error)
          })

但是我得到这个错误：

{
_type: "ns2:RoutingServiceErrorType",
type: "PermissionError",
subtype: "InvalidCredentials",
details: "Unauthorized. The request is not from an authorized source.",
metaInfo: {
timestamp: "2019-12-04T16:02:45Z",
mapVersion: "8.30.103.150",
moduleVersion: "7.2.201948-5874",
interfaceVersion: "2.6.74",
availableMapVersion: [
"8.30.103.150"
]
}
}

我尝试使用域白名单，而没有

您可以尝试执行此代码吗？

var platform = new H.service.Platform({
'apikey': 'api_key'
});
//you can remove this if you dont want to see the map.
var maptypes = platform.createDefaultLayers();

var map = new H.Map(
document.getElementById('mapContainer'),
maptypes.vector.normal.map,
{
  zoom: 10,
  center: { lng: 13.4, lat: 52.51 }
});
 // Till here

const params = {
           mode: 'fastest;car',
           waypoint0: '52.5160,13.3779',
           waypoint1: '52.5206,13.3862',
           representation: 'display',
           routeAttributes: 'summary'
         }
        function calcuateRouteFromAtoB(platform){

       var routingService = platform.getRoutingService()
        routingService.calculateRoute(params, success => {
      console.log(success.response.route[0].summary);
         }, error => {
      console.log(error);
         })
}
   calcuateRouteFromAtoB(platform);

希望这对您有帮助！

您的apikey肯定有问题。要么无效，要么它们插入方式不正确。

我用apikey尝试了您的代码，它看起来不错（只需用您自己的apikey值替换'your_apikey_string'）：

const apikey = 'your_apikey_string';

var platform = new H.service.Platform({
  'apikey': apikey
})

var params = {
  mode: 'fastest;car',
  waypoint0: 49 + ',' + 19,
  waypoint1: 49 + ',' + 19.5,
  representation: 'display',
  routeAttributes: 'summary'
}

var routingService = platform.getRoutingService()

routingService.calculateRoute(params, success => {
  console.log(success.response.route[0].summary)
}, error => {
  console.log(error)
})

尝试在此处使用地图路由服务时收到一个未经授权的错误
