经过多次测试发现是需要设置 offset=0 除非券数量超过limit，否则无值。 这个坑怨自己没领会offset的含义，汗。。。

请问解决了吗？ 我使用条件查询批次列表API https://api.mch.weixin.qq.com/v3/marketing/favor/stocks 也出现类似问题，data无值 {     "data": [],     "limit": 10,     "offset": 1,     "total_count": 3 }

重复调用wx.hideLoading()了。

请问会员卡上lever（等级）下面显示“铜牌会员”是如何实现的？（默认显示“查看”） 谢谢！

楼主，你这个图长按在安卓系统下可以识别小程序二维码，但在ios（12.4）系统（iPhone6）下识别不出。我做的图也存在这样的问题，困扰很久了。。。
