Question

我是MapHere的新手，我看到在REST API方面，我可以指定waipoint，但是我不能使用JavaScript，我尝试了一些参数，例如“ via”，但只承认了一点：

var routingParameters = {
  'routingMode': 'fast',
  'transportMode': 'car',
  // The start point of the route:
  'origin': '36.8414197,-2.4628135',
  'via': '37.9923795,-1.1305431',
  // The end point of the route:
  'destination': '40.4167047,-3.7035825',
  // Include the route shape in the response
  'return': 'polyline'
};

我在javascript网站的主页上看到了一个示例，但是我不能使用航点：

var router = platform.getRoutingService(),
  routeRequestParams = {
    mode: 'fastest;car',
    representation: 'display',
    routeattributes: 'waypoints,summary,shape,legs',
    maneuverattributes: 'direction,action',
    waypoint0: '52.5160,13.3779', // Brandenburg Gate
    waypoint1: '52.5206,13.3862'  // Friedrichstraße Railway Station
};

引发以下错误：

{"title":"Malformed request","status":400,"code":"E605001","cause":"Error while parsing request: 'origin' parameter is required\n","action":"","correlationId":"1c7bd525-b8af-4989-83a9-ab07f26a8c33"}

那么，如何发送使用航路点的请求？

我看到了问题，当.js创建url编码第二个&via=

时

https://router.hereapi.com/v8/routes?xnlp=CL_JSMv3.1.18.1&apikey=***&routingMode=fast&transportMode=car&origin=50.1120%2C8.6834&destination=52.5309%2C13.3846&via=50.1234%2C8.7654%26via%3D51.2234%2C9.1123&return=polyline

如果我解码&并且=正常工作

https://router.hereapi.com/v8/routes?xnlp=CL_JSMv3.1.18.1&apikey=***&routingMode=fast&transportMode=car&origin=50.1120%2C8.6834&destination=52.5309%2C13.3846&via=50.1234%2C8.7654&via=51.2234%2C9.1123&return=polyline

JavaScript API尚不支持（从库版本3.1.18.1开始）传递多个航路点，这意味着将点数组传递给via参数。关于这种缺乏支持的最佳选择是直接使用Routing REST API：

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}

尝试将航点与JavaScript API结合使用
