javascript - 使用 html2canvas 捕获图像后无法加载谷歌地图

Question

我想使用 html2canvas 捕捉谷歌地图图像，但问题是当我捕捉图像时，除了方向之外我看不到谷歌地图。有人可以帮我解决这个问题吗？下面是引用图片，我也附上了代码。

function getScreenShot() {

      html2canvas(document.querySelector("#map")).then(canvas => {

      var img = canvas.toDataURL();
      window.open(img);
      height=height,
      width=width

  });
 }

Before capturing image.

After capturing image.

为什么不用google map的staticmap概念？使用 staticmap 您可以轻松创建图像。您可以在下面看到相同的功能。

  function getScreenShot() {
    //google static map url
    var staticM_URL = "https://maps.googleapis.com/maps/api/staticmap";

    //Set the Google Map Center.
    staticM_URL += "?center=" + mapOptions.center.lat() + "," + mapOptions.center.lng();

    staticM_URL  += "&size=520x650";  //Set the Google Map Size. 

    staticM_URL  += "&zoom=" + mapOptions.zoom;  //Set the Google Map Zoom. 

    staticM_URL  += "&maptype=" + mapOptions.mapTypeId;//Set the Google Map Type.

    //Loop and add Markers.
    for (var i = 0; i < markers.length; i++) {
        staticM_URL  += "&markers=color:red|" + markers[i].lat + "," + markers[i].lng;
    }

   window.open(staticM_URL);
}
