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

由于某种原因，我无法建立到服务器的简单连接。我安装了最新的MySQL Community 8.0数据库以及默认设置的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
            ^

我读过一些东西，比如: 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。任何帮助都将不胜感激

如果你有权限创建一个新的用户权限，然后这样做，以正常连接node.js，这对我来说是有效的

其他回答

您可以在这里找到原始文档:https://dev.mysql.com/doc/dev/connector-nodejs/8.0/

'use strict';

const mysqlx = require('@mysql/xdevapi');

const options = {
  host: 'localhost',
  port: 33060,
  password: '******',
  user: 'root',
  schema: 'yourconference'
};

mysqlx.getSession(options)
  .then(session => {
          console.log(session.inspect());
           session.close();
  }).catch(err => {
    console.error(err.stack);
    process.exit(1);
  });

MySQL 8的完整步骤

连接MySQL

$ mysql -u root -p
Enter password: (enter your root password)

重置密码

(将your_new_password替换为您想要使用的密码)

mysql> ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY 'your_new_password';
mysql> FLUSH PRIVILEGES;
mysql> quit

然后尝试使用node连接

我有同样的问题与MySQL和我解决使用XAMPP连接MySQL和停止服务在窗口MySQL(控制面板-管理工具-服务)，并在文件夹db.js(负责数据库)，我使密码为空(在这里你可以看到:)

const mysql = require('mysql');
const connection = mysql.createConnection({
  host: 'localhost',
  user: 'root',
  password: ''
});

简单的我卸载mysql并安装mysql2来解决这个问题问题解决了。

npm uninstall mysql && npm i mysql2

检查MySQL用户的权限和用户名/密码。

对于捕捉错误，使用覆盖的_delegateError方法总是有用的。在你的情况下，这必须看起来像:

var mysql = require('mysql');

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

var _delegateError = con._protocol._delegateError;

con._protocol._delegateError = function(err, sequence) {
    if (err.fatal)
        console.trace('MySQL fatal error: ' + err.message);

    return _delegateError.call(this, err, sequence);
};

con.connect(function(err) {
  if (err) throw err;

  console.log("Connected!");
});

这个构造将帮助您跟踪致命错误。
