• 　小程序端获取二维码中带的参数

/**
     * 生命周期函数--监听页面加载
     */
    onLoad: function(option) {
        console.log(option)
        if(option.id){
          this.setData({ id: option.id });
          this.data.business_id = option.id;
          this.loadData(option.id);
        }

        //接受二维码扫码并获取二维码中的参数
        if (option.scene){
          const ids = decodeURIComponent(option.scene).split('=')[1];
          console.log("ids", ids);
          this.setData({ id: ids });
          this.data.business_id = ids;
          this.loadData(ids);
