NodeJS中的MySQL错误：无法以root身份连接

我正在使用NodeJS（8.9.0 for Windows）和MySQL（5.7.0 for Windows）的小型项目。操作系统是Windows 10 64位。NodeJS中的MySQL错误：无法以root身份连接

我的问题非常简单（在缺乏细节方面），由于我与节点缺乏经验：
这是例外的在我的MySQL安装或的NodeJS应用的MySQL的模块中的原因或者甚至在MySQL工作台的设置中？
我想设置（使用密码：YES）（在错误日志中可以看到）为NO，Node应用程序可以连接而不需要密码。 WH，但我不知道在哪里有异常禁用此

这里控制台日志：

回答：

“使用密码：YES”只意味着你的节点应用并提供密码。

“使用密码：否”表示您的Node应用程序未提供密码（或指定''作为空密码）。这是否会起作用取决于您是否在MySQL服务器中创建了没有密码的用户。

为安全起见，建议不要使用空密码创建MySQL用户 - 更不用说root用户。除非您使用TLS证书而不是密码。
