我有一個(gè)Node.js程序,它使用root帳戶連接到本地MySQL數(shù)據(jù)庫(這不是生產(chǎn)設(shè)置).

這是創(chuàng)建連接的代碼：

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!');

});

它適用于MySQL 5.7,但自從安裝MySQL 8.0后,我在啟動(dòng)Node.js應(yīng)用程序時(shí)遇到此錯(cuò)誤：

> node .\api-server\main.js

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

C:\Users\me\project\node_server\node_modules\mysql\lib\protocol\Parser.js:80

throw err; // Rethrow non-MySQL errors

似乎root帳戶使用新密碼哈希方法：

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

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

| User | Host | plugin |

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

| root | localhost | caching_sha2_password |

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

…但我不知道為什么Node.js無法連接到它.我已經(jīng)更新了所有的npm軟件包,但仍然存在問題.

我想保留新密碼哈希方法.我還可以使這個(gè)連接工作嗎？我是否必須等待更新MySQL Node.js包,或更改我的設(shè)置？

總結(jié)
