关于arcgis:arcgis-for-js-缓冲分析

this.view.on('click', (evt) => {
        let layer = this.map.findLayerById('layerbjx')
        // 创立查问对象
        let query = layer.createQuery()
        // 将点击的点放入查问对象中
        query.geometry = {
          type: 'point',
          longitude: evt.mapPoint.longitude,
          latitude: evt.mapPoint.latitude
        }
        // 设置缓冲区
        query.distance = 6
        // 设置查问形式（相交）
        query.spatialRelationship = 'intersects'
        layer.queryFeatures(query).then((res) => {
          // 失去features对象
          console.log(res.features)
        })
      })
