我查了一些资料，一开始我没有加_openid，有大佬说表中没有这个无法判断是不是开发者操作，我加上了我自己的openid还是不行；
然后还有人说权限问题，我把权限都改成了true，还是不行，怎么改都返回null并且数据也没有更新，困扰了很久，希望大佬指点一下！

I checked some information, but I didn't add it at first_ Openid, some bosses said that it was impossible to judge whether it was operated by developers without this in the table. I still couldn't add my own openid; Then someone said about the permission problem. I changed the permission to true, but it still didn't work. How to change it, it returned null and the data was not updated. It has been bothered for a long time. I hope the boss can give me some advice!
回答：
云函数的结构贴下？
你可以先检查下，主函数有return吗？
无论fail还是success的情况
自己看下云函数日志
