MySQL 8.0-客户端不支持服务器请求的身份验证协议；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连接。我使用默认设置安装了最新的MySQL Community 8.0数据库以及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

但是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'

当root作为用户 localhost的您的网址，并password为您的密码

然后运行以下查询以刷新特权：

flush privileges;

完成后尝试使用节点连接。

如果那行不通，请尝试一下@'localhost'。
