HERE-API-如何创建app_id，app_code和api_key

问题描述

我正尝试从(https://tcs.ext.here.com/examples/v3.1/fleet_telematics_api )进入我的应用程序，但是身份验证需要app_id和app_code，我只有一个api_key.我希望能够创建truckOverlayProvider来显示和隐藏卡车限制.我需要什么，如何实现呢?该主题是否有逐步的教程?

I'm trying to replicate the examples from the fleet telematics examples at (https://tcs.ext.here.com/examples/v3.1/fleet_telematics_api) into my app, but the authentication need app_id and app_code, I have only an api_key.I want to be able to create the truckOverlayProvider to show and hide the truck restrictions.What do I need and how can I achieve that, is there any tutorial step by step for this subject?

推荐答案

查看您共享的示例的代码，这是他们如何呼吁使用卡车覆盖的方法:

Looking at the code for the example that you shared, here's how they are making the call for truck overlay:

var truckOverlayProvider = new H.map.provider.ImageTileProvider({
    label: "Tile Info Overlay",
    descr: "",
    min: 12,
    max: 20,
    getURL: function(col, row, level) {
        server_rr++;
        if (server_rr > 4) server_rr = 1;
        return ["https://",
            server_rr,
            ".base.maps.api.here.com/maptile/2.1/truckonlytile/newest/normal.day/",
            level,
            "/",
            col,
            "/",
            row,
            "/256/png8",
            "?style=fleet",
            "&app_code=",
            app_code,
            "&app_id=",
            app_id
        ].join("");
    }
});
var truckOverlayLayer = new H.map.layer.TileLayer(truckOverlayProvider);
map.addLayer(truckOverlayLayer);
