我这样获取scene有不对的地方吗？打印query为空

onLoad:function(query) {

    let that = this;

    if (query.scene){

      const scene = decodeURIComponent(query.scene)

      var id = scene.split(’&’)[0].split(’=’)[1]

      var shopName = scene.split(’&’)[1].split(’=’)[1]

      that.setData({

        sid: id,

        shopName: shopName

      })

    }

}
