Question

我有一个项目，在这里使用带有标记的地图。我从旧项目中复制了代码，然后粘贴到了新项目上，但是它开始给我这个错误：

Failed to execute ‘postMessage’ on ‘DOMWindow’: The target origin provided (‘https://developer.here.com’) does not match the recipient window’s origin (‘http://127.0.0.1:5500’).

代码如下：

!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">

    <script type="text/javascript">window.ENV_VARIABLE = 'https://developer.here.com'</script>
    <script src='https://developer.here.com/javascript/src/iframeheight.js'></script>
    </head>
    <body>
        <div id="map"></div>
        
        <script>
      /**
 * Moves the map to display over Berlin
 *
 * @param  {H.Map} map      A HERE Map instance within the application
 */
function moveMapToBerlin(map){
  map.setCenter({lat:52.5159, lng:13.3777});
  map.setZoom(14);
}

/**
 * Boilerplate map initialization code starts below:
 */

//Step 1: initialize communication with the platform
// In your own code, replace variable window.apikey with your own apikey
var platform = new H.service.Platform({
  apikey: 'i put my api key here'
});
var defaultLayers = platform.createDefaultLayers();

//Step 2: initialize a map - this map is centered over Europe
var map = new H.Map(document.getElementById('map'),
  defaultLayers.vector.normal.map,{
  center: {lat:xxx, lng:xxx},
  zoom: 4,
  pixelRatio: window.devicePixelRatio || 1
});
// add a resize listener to make sure that the map occupies the whole container
window.addEventListener('resize', () => map.getViewPort().resize());

//Step 3: make the map interactive
// MapEvents enables the event system
// Behavior implements default interactions for pan/zoom (also on mobile touch environments)
var behavior = new H.mapevents.Behavior(new H.mapevents.MapEvents(map));

// Create the default UI components
var ui = H.ui.UI.createDefault(map, defaultLayers);

// Now use the map as required...
window.onload = function () {
  moveMapToBerlin(map);
}
  </script>
</body>
</html>

我很困惑。我尝试检查我的API密钥，更改经度和纬度，但似乎无济于事。

在第五个window.ENV_VARIABLE = 'https://developer.here.com'中将window.ENV_VARIABLE = 'http://127.0.0.1:5500'更改为<script>。
