retrieve data from a post request nodeJS
Question
i have a super simple form
index.html:
<html>
<body>
PAGE
<form method = "post" action="/login">
pseudo: <input type="text" name="username"><br>
mdp: <input type="password" name="password">
<input type="submit" value="post">
</form>
</body>
</html>
and a server.js file:
/******** Chargement des Middleware *********/
const bodyParser = require('body-parser');
/******** Declaration des variables *********/
/******** Configuration du serveur NodeJS - Port : 30002 *********/
const express = require('express');
const app = express(); // appel a expressJS
const server= app.listen(3116,function(){
console.log('listening on port 3116');
});
app.use(bodyParser.urlencoded({ extended: true }));
app.use(bodyParser.json({limit: '10mb'}));
/******** Gestion des URI ********/
app.get('/', function(request, response) {
response.sendFile('CERIGame/index.html',{ root: __dirname });
});
app.post('/login', function(req, res) {
var username = req.body.username;
var password = req.body.password;
console.log("post received: %s %s", username, password);
});

I ran your code on my machine and found everything working except one issue, you have to return the response from the /login API. Please find the code for returning response from server below.
app.post('/login', function(req, res) {
var username = req.body.username;
var password = req.body.password;
console.log("post received: %s %s", username, password);
return res.json({"success": 1})
});
Just for your information when running on your local machine the web app should be at http://localhost:3116 .
