本文主要是介绍2021.12.19报错解决:UnhandledPromiseRejectionWarning: MongoError: command find requires authentication,希望对大家解决编程问题提供一定的参考价值,需要的开发者们随着小编来一起学习吧!
解决思路:
1.查看报错原因,翻译后了解原因
UnhandledPromiseRejectionWarning: MongoError: command find requires authentication
2.通过百度查询查看相似问题,通过博客:https://blog.csdn.net/w_hx10/article/details/109538770
知道是因为之前设置过mongodb的权限,所以访问时需要添加一些设置
3.按照博客进行修改,问题解决
总结:认真查看别人写的博客,要耐下性子去看别人的博客(之前看过几遍这个人的博客,但是忽视了这个博客)
