/**
 * @params sumary  Map() 所有数据的集合
 * @params bundling  Map() 套装数据的集合
 * @params goods_list  需要遍历的数据 array, 每个item是object, goods_id, goods_num, bl_id // bl_id > 0,查bundling 反之goods_id查sumary
 */
// bl_id: 12, bl_name: "222", bl_price: 122, goods: Array(4), goods_num: 3 有套餐返回的数据样式， 渲染时判断bl_id 再循环goods即可。。。 goods_num通用
