Node.js，连接到phpMyAdmin中的数据库

Question

I am trying to query a database on my website's hosting service (HostWinds). However, when I run the following code nothing happens. No error, no console logs, nothing.

I found this code from W3 schools guide on MySQL and Node.js.

var mysql = require('mysql');

var con = mysql.createConnection({
  host: "webmaxlabs.com",
  user: "abc",
  password: "123",
  database: "USER_wp4"
});

con.connect(function(err) {
  if (err) throw err;
  con.query("SELECT * FROM wp_posts", function (err, result, fields) {
    if (err) throw err;
    console.log(result);
  });
});

I have MySQL installed, and I'm using the same username and password I use to login to HostWinds. I am also pretty sure I have the right database name. Is my host misnamed? I am not really sure what to use since 'localhost' can't be correct, right? WebMaxLabs.com is listed as my 'Main Domain' in my cPanel. So I figured it might be my host, but I am really not sure. My

Any feedback or information would be very much appreciated. Thank you!

 const express = require('express'); const mysql = require("mysql"); const app = express() var con = mysql.createConnection({ host: 'localhost', user: 'root', password: '', database: 'test' }); con.connect(function (err) { if (err) { console.log('Error connecting to Db'); return; } console.log('Connection established'); }); app.get("/", (req, res) => { const sqlInsert = "INSERT INTO movie (movie_name,movie_review) VALUES ('inception','good movie')"; con.query(sqlInsert, (error, result) => { res.send("Data send to the Database") }) }) app.listen(3001, () => { console.log("running on port 3001") })
