我有一个Node.js程序,它使用root帐户连接到本地MySQL数据库(这不是生产设置).

这是创建连接的代码：

const mysql = require('mysql');

const dbConn = mysql.createConnection({

host: 'localhost',

port: 3306,

user: 'root',

password: 'myRootPassword',

database: 'decldb'

});

dbConn.connect(err => {

if (err) throw err;

console.log('Connected!');

});

它适用于MySQL 5.7,但自从安装MySQL 8.0后,我在启动Node.js应用程序时遇到此错误：

> node .\api-server\main.js

[2018-05-16T13:53:53.153Z] Server launched on port 3000!

似乎root帐户使用新密码哈希方法：

> select User,Host,plugin from user where User="root";

+------+-----------+-----------------------+

| User | Host | plugin |

+------+-----------+-----------------------+

| root | localhost | caching_sha2_password |

+------+-----------+-----------------------+

…但我不知道为什么Node.js无法连接到它.我已经更新了所有的npm软件包,但仍然存在问题.

我想保留新密码哈希方法.我还可以使这个连接工作吗？我是否必须等待更新MySQL Node.js包,或更改我的设置？
