cesium 加载geoJson格式的图斑

Cesium加载geoJson 格式的图斑方法：

// 首次进来判断是否存在图斑 
if(this.geoSource) {
    this.Global.viewer.dataSources.remove(this.Global.viewer.dataSources.getByName('图斑')[0])
 }
let geoData = {
  "type": "FeatureCollection", "features": [
      { "type": "Feature", "geometry": { "type": "Polygon", "coordinates": this.coordinates}, "properties": { "Id": 0 } }
  ]}
this.geoSource = Cesium.GeoJsonDataSource.load(geoData,{
  stroke:Cesium.Color.YELLOW,
  fill:Cesium.Color.YELLOW.withAlpha(0.5),
  strokeWidth: 8,
  clampToGround: true //是否贴地
  })
  this.geoSource.then((res) => {
  this.Global.viewer.dataSources.add(res);
  res.name = '图斑'
})

补充geoJson 可是作为示例

{type": "FeatureCollection", "features": [
      { "type": "Feature", "geometry": { "type": "Polygon", "coordinates": [
