Question

我对node-mysql很陌生，想连接到外部数据库。数据库已启动并正在运行，因为我能够使用相同的凭据（甚至通过MySQL Administrator工具）通过mysql CLI连接到它。服务器的MySQL版本是“ 5.1.60-log MySQL Community Server”。但是，使用mysql-node-module时，出现以下错误：

C:\Users\JohnDoe\databaseIntegration\node_modules\mysql\lib\protocol\Parser.js:437
      throw err; // Rethrow non-MySQL errors
      ^

Error: ER_HANDSHAKE_ERROR: Bad handshake

即使使用数据库的本地1：1副本，我也可以连接，进行查询和console.log结果。因此，我猜测node-mysql数据库兼容性肯定有问题。这是“我写的”代码：

const mysql = require('mysql');

var con = mysql.createConnection({
    user: 'myuser',
    password: 'mypw',
    database: 'dbdb',
    host: 'dbip',
    port: 'dbport',
    insecureAuth: true
});

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

    con.query(`SELECT * FROM mytable;`, function (err, result) {
        if (err) throw err;
        console.log("Result: " + JSON.stringify(result));
    });
});

这里可能是什么问题，我该如何解决？谢谢！
