MySQL 8.0 - 客户端不支持服务器请求的认证协议(protocol)；考虑升级 MySQL 客户端

Question

由于某种原因，我无法与服务器建立简单的连接。我使用默认设置安装了最新的 MySQL Community 8.0 数据库和 Node.JS。

这是我的 node.js 代码

    var mysql = require('mysql');

    var con = mysql.createConnection({
      host: "localhost",
      user: "root",
      password: "password",
      insecureAuth : true
    });

    con.connect(function(err) {
      if (err) throw err;
      console.log("Connected!");
    });

以下是在命令提示符中发现的错误:

C:\Users\mysql-test>node app.js
    C:\Users\mysql-test\node_modules\mysql\lib\protocol\Parse
    r.js:80
            throw err; // Rethrow non-MySQL errors
            ^

我已经阅读了一些内容，例如: https://dev.mysql.com/doc/refman/5.5/en/old-client.html https://github.com/mysqljs/mysql/issues/1507

但我仍然不确定如何解决我的问题。任何帮助将不胜感激:D

在MYSQL Workbench中执行以下查询

ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY 'password';

其中 root 作为您的用户localhost 作为你的 URL和 password 作为您的密码

然后运行此查询以刷新权限:

刷新权限；

完成后尝试使用 Node 连接。

如果这不起作用，请尝试不使用 @'localhost' 部分。
