【问题描述】:
参考这个 mapbox-gl-js 的例子... https://www.mapbox.com/mapbox-gl-js/example/3d-extrusion-floorplan/
当我使用我的 api 密钥运行此示例代码时,我只得到以“自然历史自然历史博物馆”为中心的地图,而没有突出任何墙壁。我在这里想念什么?其他示例似乎可以直接使用复制粘贴。

【问题讨论】:
-
它在jsbin.com/vevefalope/edit?html,output 为我工作,您在尝试时是否在控制台中看到错误?
-
我认为您的 geojson 加载有问题,请自己托管 geojson 或将 json 复制并粘贴到您的代码中。
-
改用
'data': 'https://cors-anywhere.herokuapp.com/https://www.mapbox.com/mapbox-gl-js/assets/data/indoor-3d-map.geojson'(即在URL前加上https://cors-anywhere.herokuapp.com/),有关说明,请参阅如何使用CORS代理绕过“无访问控制” -stackoverflow.com/questions/43871637/…stackoverflow.com/questions/43871637/…答案的“允许来源标题”问题部分
