1.vite-plugin-cesium

// vite-plugin-cesium 是一个 Vite 插件，用于在 Vite 项目中轻松集成和使用 Cesium 地图引擎。它简化了在 Vite 项目中使用 Cesium 的配置和引入过程。

// 具体来说，vite-plugin-cesium 主要提供了以下功能：

// 自动引入 Cesium：通过 vite-plugin-cesium 插件，在 Vite 项目中可以直接引入 Cesium，无需手动配置复杂的路径等信息。

// 处理 Cesium 的依赖关系：Cesium 本身有一些依赖关系需要处理，vite-plugin-cesium 可以帮助自动处理这些依赖，确保 Cesium 在 Vite 项目中正常运行。

// 优化加载：vite-plugin-cesium 可以优化 Cesium 的加载方式，避免不必要的网络请求和加载时间，提高项目性能。

// 总的来说，vite-plugin-cesium 简化了在 Vite 项目中使用 Cesium 的流程，使得开发者更容易地集成 Cesium 地图引擎到他们的项目中，并且提供了一些优化功能来改善用户体验。

根据屏幕点击获取经纬度，进行arcgis服务查询

let _this = this
let handler = new Cesium.ScreenSpaceEventHandler(viewer.scene.canvas);
handler.setInputAction(function (event) {
let pick = viewer.scene.pick(event.position);
let ray = viewer.camera.getPickRay(event.position);
```
   const position = event.position;
   let cartesian = viewer.camera.pickEllipsoid(position, viewer.scene.globe.ellipsoid);
   // 将世界坐标转换为地理坐标（经度和纬度）
   let cartographic = Cesium.Cartographic.fromCartesian(cartesian);
   let longitude = Cesium.Math.toDegrees(cartographic.longitude);
   let latitude = Cesium.Math.toDegrees(cartographic.latitude);
   if (pick && pick.id._type) {
     let obj = pick.id;
   } else {
     _this.$emit('getPointHandle', [longitude, latitude])
   }
 }, Cesium.ScreenSpaceEventType.LEFT_CLICK)
```
// 获取点击点位信息
getPointHandle (coordinate) {
this.coordinate = coordinate
let allLayers = viewer.imageryLayers._layers
this.queryLayers = allLayers.filter(item => item.show && (item.imageryProvider.layerName === '公益林优化调整数据' || item.imageryProvider.layerName === '管护小班'))
