其实这一路看过来没发现啥问题，基本上是谁也不会觉得代码有问题

原因分析：

提示：Unable to connect to Redis

这意思是说无法连接到Redis

当时是看完代码觉得没问题又去F12检查页面，当然我还是没看出啥问题

Unable to connect to Redis无法连接到Redis解决的全过程

解决方案：

提示：缺少Redis环境

最后有幸得到一位大佬帮助，他告诉我是缺少环境

Unable to connect to Redis无法连接到Redis解决的全过程

最后运行成功！

Unable to connect to Redis无法连接到Redis解决的全过程

在管理员后台列表中也可以看到数据
