是否可以通过mapbox gl访问mbtile中的元数据/层？

mapboxgl.accessToken = 'your-access-token';
var map = new mapboxgl.Map({
  container: 'map',
  style: 'mapbox://styles/mapbox/streets-v11',
  center: [-74.5, 40],
  zoom: 9
});

map.on('load', function() {
  map.addSource('mbtiles-source', {
    type: 'raster',
    tiles: ['mbtiles://path/to/your/mbtiles/file/{z}/{x}/{y}.png'],
    tileSize: 256
  });

  map.addLayer({
    id: 'mbtiles-layer',
    type: 'raster',
    source: 'mbtiles-source',
    minzoom: 0,
    maxzoom: 22
  });

  // 获取MBTiles的元数据
  var metadata = map.getSource('mbtiles-source').tiles[0].metadata;
  console.log(metadata);

  // 获取MBTiles的层
  var layers = map.getStyle().layers.filter(function(layer) {
    return layer.source === 'mbtiles-source';
  });
  console.log(layers);
});
