在这里，使用 api 密钥无法访问 Fleet Telematics CalculateRoute 服务。

Question

我试图使用Here Fleet Telematics CalculateRoute.json服务来计算行程成本（收费等）。示例页面使用api_id和api_key进行验证。在我的(Freemium)账户中，我没有看到可以生成这些的方法。

我所做的是复制样本网站的请求，并将app_id和app_key参数替换为 apikey=**key**. 我还去掉了jsoncallback参数.我得到了后面的JSON。

{
  "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."
}

Update:我希望实现的，是使用POST的http方法。根据 https:/developer.here.comdocumentationfleet-telematicsapi-reference.html。在 "计算具有附加车队远程信息处理功能的路线 "一节中，应该可以做到这一点。

确切的请求信息是（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",
    "trailerType": "2",
    "trailersCount": "1",
    "vehicleNumberAxles": "3",
    "trailerNumberAxles": "2",
    "hybrid": "0",
    "emissionType": "5",
    "fuelType": "diesel",
    "height": "4m",
    "trailerHeight": "400",
    "vehicleWeight": "12000",
    "limitedWeight": "40t",
    "disabledEquipped": "0",
    "minimalPollution": "0",
    "hov": "0",
    "passengersCount": "1",
    "tiresCount": "14",
    "commercial": "1",
    "heightAbove1stAxle": "1m",
    "width": "2.55",
    "length": "16.5",
    "mode": "fastest;truck;traffic:disabled",
    "rollups": "none,country;tollsys",
    "alternatives": "1"
}

这将返回以下内容。

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

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

而在GET请求中传递所有相同的值作为url参数则是可行的。

你需要使用以下终端。

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

请看 发送请求 和 计算收费成本 文件页。
