Question

my script is here
var mysql= require('mysql');
var connection = mysql.createConnection({
  host: 'localhost',
  user: 'root',
  password: '12345',
  database: 'mydb'
});

connection.connect(function(err) {
  if (err) {
    console.error('error connecting: ' + err.stack);
    return;
  }

 console.log('connected as id ' + connection.threadId);
});

当我运行此代码时，它显示此错误

用户名和密码以及所有其他详细信息都是正确的

我使用的导出功能与您的功能完全相同，而且运行正常。

var mysql = require("mysql");
var self = module.exports = {

    db:{},
    init: function(login, callback) {
        self.db = mysql.createConnection({
            host:'myHost',
            user:'myUser',
            password:'myPassword',
            database:'myDbName'
        });
        return self.db.connect(function(err) {
            if (err) {
                callback(null);
            }
            else {
                callback(self.db);
            }
        });
    },
    execute:function(login, request, callback) {
        return self.db.query(request, function(err, rows, fields) {
            if (err) {
                callback(null);
            }
            else {
                callback(rows);
            }
        });
    }
};
