宿命论是那些缺乏意志力的弱者的借口。——罗曼·罗兰

今天试了试使用js连接数据库，发现报错Client does not support authentication protocol requested by server; consider upgrading MySQL client

乍一看，代码好像没问题

var mysql = require("mysql");

let connection = mysql.createConnection({
    host: "127.0.0.1",
    port: 3306,
    user: "root",
    password: "789456",
    database: "ruben"
});

connection.connect();

connection.query("select * from user", function (error, results, fields) {
    if (error) throw error;
    console.log(results);
    console.log(fields);
});


connection.end();

但我的mysql版本是8.0.22

所以需要执行以下sql

alter user 'root'@'localhost' identified with mysql_native_password by '789456';
flush privileges;

然后就可以正常执行了
