KML 图层未加载

Question

我正在尝试在 Google 地图上加载一个简单的 KML 图层。我无法使其适用于特定图层，同时其他类似的 KML 图层加载正常。这是代码的最小版本：https://jsfiddle.net/eundas/0fhqmocv/4/ 为什么这不起作用？它与我的代码有关还是与 KML 的结构有关？我将不胜感激。

var map;
var options = {
  zoom: 5,
  center: new google.maps.LatLng(-33.5, -70),
  mapTypeId: google.maps.MapTypeId.ROADMAP,
  scaleControl: true
};
map = new google.maps.Map(document.getElementById("mapcanvas"), options);

var Coquimbo4204Layer = new google.maps.KmlLayer({
    url: 'https://drive.google.com/uc?export=download&id=1bCBH784phTY_wK0WZiAbbDRlXb1dJsv7'
});
google.maps.event.addListener(Coquimbo4204Layer, 'status_changed', function() {
console.log(Coquimbo4204Layer.getStatus());
})
Coquimbo4204Layer.setMap(map);

Answer 1

使用发布的代码，我得到 FETCH_ERROR，根据文档，这意味着：The document could not be fetched.

如果 url 是 http: 而不是 https:（这似乎是 Google 驱动器的问题）。

console.log(Coquimbo4204Layer.getStatus());
})
Coquimbo4204Layer.setMap(map);

#mapcanvas {
  height: 500px;
  width: 500px;
  background: blue;
  margin: 0px;
  padding: 0px;
}
