{"errcode":40029,"errmsg":"invalid code, rid: 64d4aebe-4b6d1523-243a35fa"}

根据引用中提到的情况，出现{"errcode":40029,"errmsg":"invalid code, rid: 64d4aebe-4b6d1523-243a35fa"}的错误是因为微信网页授权过程中，传给后端的code没有被正确消费。根据作者的经验，他们发现问题出在大小写的处理上。他们在拿链接上的code时，将其强制处理成小写导致了错误。建议检查一下自己拿链接上code的方法是否对大小写进行了正确的处理。这个小小的疏忽可能导致一整天的问题。<em>1</em>
