Question

我正在构建 nodejs短信应用 。这个应用程序将在cPanel中拥有的另一个网站的MySQL数据库中获取数据（电话号码）（例如 example.org ） strong>手机，值手机。这是我到目前为止所得到的错误。请帮助说明下面任何可能的错误原因。我是初学者，正在做我的第一个项目，我将在heroku中主持。

var express  = require("express");
var mysql = require("mysql");
var app = express();

//Establishing connection
var con = mysql.createConnection({
	host:"example.org",
	user:"example_admin",
	password:"*********",
	database:"example_registerdb"
});

//Fetching the phone numbers from the phone column
con.connect(function(err){
	if(err) throw err;
	con.query("SELECT phone FROM phone", function(err, results, fields){
		if(err) throw err;
		console.log(results);
	});
});

app.get('/', function(req, res){
	res.send('Hello World');
});

var server = app.listen(3306, function(){
	console.log('Listening on port 3306');
});
