Leaflet使用vector tiles样式设置

    //point style
    var myIcon = L.icon({
        iconUrl: 'css/images/dian.svg',
//      shadowUrl: 'css/images/leaf-shadow.png',
        iconSize:     [50, 50], // size of the icon
//      shadowSize:   [50, 64], // size of the shadow
        iconAnchor:   [10, 50], // point of the icon which will correspond to marker's location
//      shadowAnchor: [4, 62],  // the same for the shadow
//      popupAnchor:  [-3, -76] // point from which the popup should open relative to the iconAnchor
    });
    //样式设定
    var vectorTileStyling = {
             //layer样式,line没有fill属性
            gj:{//layername
