按照如下代码接入天地图，地图一片空白，如何解决

Answer 1

您好，看一下控制台有什么报错么，我试了一下能出图，以下是我测试的代码，可供参考

proj4.defs("EPSG:4490","+proj=longlat +ellps=GRS80 +no_defs");
    var crs =new L.Proj.CRS("EPSG:4490",{
        bounds: L.bounds([-180,-90], [180,90]),
        origin:[-180,90],
    });
      var map = L.map('map', {
        center: [0, 0],
        zoom: 0,
       crs: crs,
      });
      L.supermap
        .tiandituTileLayer({
          key: '1d109683f4d84198e37a38c442d68311'
        })
        .addTo(map);
