在GoogleMap中导入和解析KML文件

Question

我正在尝试将Google Maps API与直接在Google Maps平台中创建的新图层一起使用，并导出为.kml文件。使用的指南是Google Developer's门户网站上的主要指南。

但是，似乎KML文件无法正确加载。 http://1c.1contact.ch/mandats/map1.html

连接和加载地图的代码如下（它改编自https://developers.google.com/maps/documentation/javascript/kmllayer）：

<script>
  var map;
  var src = 'http://1c.1contact.ch/file/2573/GE.kml';

  /**
  * Initializes the map and calls the function that loads the KML layer.
  */
  function initMap() {
  map = new google.maps.Map(document.getElementById('map'), {
  center: new google.maps.LatLng(-19.257753, 146.823688),
  zoom: 2,
  mapTypeId: 'terrain'
  });
  loadKmlLayer(src, map);
  }

  /**
  * Adds a KMLLayer based on the URL passed. Clicking on a marker
  * results in the balloon content being loaded into the right-hand div.
  * @param {string} src A URL for a KML file.
  */
  function loadKmlLayer(src, map) {
  var kmlLayer = new google.maps.KmlLayer(src, {
  suppressInfoWindows: true,
  preserveViewport: false,
  map: map
  });
  google.maps.event.addListener(kmlLayer, 'click', function(event) {
  var content = event.featureData.infoWindowHtml;
  var testimonial = document.getElementById('capture');
  testimonial.innerHTML = content;
  });
  }
</script>

实现这个.KML用法的正确方法是什么？

祝福，
