Cesium

// 非百度地图
viewer.imageryLayers.addImageryProvider(new Cesium.UrlTemplateImageryProvider({
  url: 'http://localhost:7099/{z}/{x}/{y}.png'
}))
// 百度地图（需自定义BaiduImageryProvider），可参考cesium-helper目录下代码
import BaiduImageryProvider from './cesium-helper/BaiduImageryProvider/BaiduImageryProvider.js'
viewer.imageryLayers.addImageryProvider(new BaiduImageryProvider({
  url: 'http://localhost:7099/{z}/{x}/{y}.png'
}))
