关于arcgis:arcgis加载wtms数据

这是wtms服务地址，肯定要记得加tile

export const CustomWMTS = async (val) => {  let BaseTileLayer = await arcgisPackage.BaseTileLayer;  let Request = await arcgisPackage.Request;  let TDT = await BaseTileLayer.createSubclass({    properties: {      urlTemplate: null,      layerType:'wmts'    },    getTileUrl: function (level, row, col) {      let url =val + level + '/' + row + '/' + col      return url;    },    fetchTile: function (level, row, col) {      let url = this.getTileUrl(level, row, col);      return Request(url, {        responseType: "image",      }).then((response) =>{        let image = response.data;        let width = this.tileInfo.size[0];        let height = this.tileInfo.size[0];        let canvas = document.createElement("canvas");        let context = canvas.getContext("2d");        canvas.width = width;        canvas.height = height;        context.drawImage(image, 0, 0, width, height);        return canvas;      })    },  });  let layer = await new TDT();  return layer}
