此处 Fleet Telematics CalculateRoute 服务无法使用 api 键访问

Question

我正在尝试使用 Here Fleet Telematics CalculateRoute.json 服务来计算行程费用（通行费等）。示例页面使用 api_id 和 api_key 进行身份验证。在我的（免费增值）帐户中，我看不到可以生成它的方法。

我所做的是复制示例站点发出的请求，并将 app_id 和 app_key 参数替换为 apikey=**key**。我还删除了 jsoncallback 参数。我得到了以下 JSON:

的支持

{
  "faultCode": "s14e781b4-b577-4b58-86bb-359ee5c8a979",
  "responseCode": "400",
  "message": "The request is missing the app_id and app_code parameters. They must both be passed as query parameters. If you do not have app_id and app_code, please obtain them through your customer representative or at http://developer.here.com/myapps."
}

更新：我希望实现的是使用 POST http 方法。根据 https://developer.here.com/documentation/fleet-telematics/api-reference.html 部分 "Calculates a route with additional fleet telematics features"，这应该是可能的。

确切的请求消息是（没有实际的 api 密钥）：

POST https://fleet.ls.hereapi.com/2/calculateroute.json
Content-Type: application/json

{
    "apiKey": "**SNIP**",
    "waypoint0": "38.72639,-9.14949",
    "waypoint1": "47.54881,7.58782",
    "detail": "1",
    "maneuverAttributes": "none",
    "linkAttributes": "none,sh",
    "legAttributes": "none,li",
    "currency": "EUR",
    "departure": "",
    "tollVehicleType": "3",

    "emissionType": "5",
    "fuelType": "diesel",
    "height": "4m",
    "trailerHeight": "400",
    "vehicleWeight": "12000",
    "limitedWeight": "40t",

    "heightAbove1stAxle": "1m",
    "width": "2.55",
    "length": "16.5",
    "mode": "fastest;truck;traffic:disabled",
    "rollups": "none,country;tollsys",
    "alternatives": "1"
}

这个 returns 以下:

HTTP/1.1 401 Unauthorized
Content-Type: application/json
Date: Mon, 01 Jun 2020 11:10:09 GMT
Server: nginx-clojure
Content-Length: 74
Connection: Close

{
  "error": "Unauthorized",
  "error_description": "Token or apiKey is missing."
}

而在 GET 请求中传递所有与 url 参数相同的值是可行的。

Answer 1

您需要使用以下端点：

https://fleet.ls.hereapi.com/2/calculateroute.json?apiKey={YOUR_API_KEY}&...

请参阅 Send a Request and Calculate Toll Cost 文档页面。
