function geoIntersects(IOptions): Command

interface IOptions {
  geometry: Point | LineString | MultiPoint | MultiLineString | Polygon | MultiPolygon // 地理位置
}

示例代码:找出和一个多边形相交的记录

const db = wx.cloud.database()
const _ = db.command
const { Point, LineString, Polygon } = db.Geo
db.collection('restaurants').where({
  location: _.geoIntersects({
    geometry: Polygon([
      LineString([
        Point(0, 0),
        Point(3, 2),
        Point(2, 3),
        Point(0, 0)
      ])
    ]),
  })
})
