我是使用 OpenLayers 的新手(一个开源 JavaScript 库，用于在 Web 浏览器中将 map 数据显示为滑动 map )。我将它与 Thymeleaf(一种 Java XML/XHTML/HTML5 模板引擎，可以在 Web 和非 Web 环境中工作)一起使用。
我试图重现此示例，但从服务器获取资源 https://openlayers.org/en/latest/examples/reprojection-wgs84.html
我有这个页面:
<!doctype html>
<html lang="en" xmlns:th="http://www.thymeleaf.org">

<script src="https://cdn.jsdelivr.net/gh/openlayers/openlayers.github.io@master/en/v6.3.1/build/ol.js"></script>

/*<![CDATA[*/
import Map from '/css/Map';
import View from '/css/View';
import TileLayer from '/css/layer/Tile';
import OSM from '/css/source/OSM';
var map = new Map({
layers: [
new TileLayer({
source: new OSM()
})
],
target: 'map',
view: new View({
projection: 'EPSG:4326',
center: [0, 0],
zoom: 2
})
});
/*]]>*/
</script>
</div>
</div>

</div>
</div>
</div>

</div>
</body>
</html>
我想知道如何从服务器获取这些对象:
import Map from '/css/Map';
import View from '/css/View';
import TileLayer from '/css/layer/Tile';
import OSM from '/css/source/OSM';
最佳答案
不知道是什么意思，但如果“从服务器获取”意味着直接从编译源访问导入(无论是在您的服务器上还是在其他地方)，这是如何做到的:
const Map = window.ol.Map;
const View = window.ol.View;
const TileLayer = window.ol.layer.Tile;
const OSM = window.ol.source.OSM;
var map = new Map({
layers: [
new TileLayer({
source: new OSM()
})
],
target: 'map',
view: new View({
projection: 'EPSG:4326',
center: [0, 0],
zoom: 2
})
});<link href="https://cdn.jsdelivr.net/gh/openlayers/openlayers.github.io@master/en/v6.3.1/css/ol.css" rel="stylesheet"/>
<script src="https://cdn.jsdelivr.net/gh/openlayers/openlayers.github.io@master/en/v6.3.1/build/ol.js"></script>
<style>
.map {
width: 100%;
height: 400px;
}
</style>
<div id="layout">
