NodeJS中的MySQL错误：无法以root身份连接

我正在开发一个使用NodeJS（Windows为8.9.0）和MySQL（Windows为5.7.0）的小项目。操作系统是WIndows 10 64位。

由于我缺乏Node的经验，我的问题相当简单（缺乏细节）： 在我的mysql安装或NodeJS应用程序的mysql模块中，甚至在MySQL工作台的设置中，是这个异常的原因吗？ 我想设置（使用密码：YES），可以在错误日志中看到NO，Node应用程序可以连接而不需要密码。 wh，但我不知道在哪里禁用它

这里的控制台日志有例外：

“使用密码：是”仅表示您的节点应用确实提供了密码。

“使用密码：否”表示您的节点应用程序未提供密码（或指定''作为空密码）。这是否有效取决于您是否在MySQL服务器中创建了没有密码的用户。

出于安全原因，不建议使用空密码创建MySQL用户 - 更不用说root用户。除非您使用TLS证书而不是密码。
