前端学习openLayers配合vue3（加载线上数据源）

现在我们学习一下加载网上的线上数据再加上点矢量图层，紧接着上一步

关键代码

 layers: [
        //瓦片图层source第三方，或者自带的,地图的底层
        new TileLayer({
          // source: new OSM(),//内置的国外地址，需要代理
          source: new XYZ({
            url: "http://wprd0{1-4}.is.autonavi.com/appmaptile?x={x}&y={y}&z={z}&lang=zh_cn&size=1&scl=1&style=7",
          }), //国内第三方数据源
        }),
        // 矢量图层
        new VectorLayer({
          source: new VectorSource({
            url: "https://geo.datav.aliyun.com/areas_v3/bound/100000_full.json",
            format: new GeoJSON(),
          }),
        }),
      ],
