POST data using node.js
Question
I'm trying to get form data to node server using POST method. This is my HTML code,
<html>
<head>
<title>
Node Architecture
</title>
</head>
<body>
<h1>Node Architecture</h1>
<h3>Enter Your name.</h3>
<form action="/" method="POST">
<input type="text" name="eventname" />
<input type="submit" value="Go" />
</form>
</body>
</html>
This is my node app, index.js
var app = require('express')();
var http = require('http').Server(app);
//var io = require('socket.io')(http);
//var qs = require('querystring');
app.get('/', function(req, res){
res.sendfile('index.html');
});
app.get('/events', function(req, res){
res.sendfile('events.html');
});
app.get('/movie', function(req, res){
res.sendfile('movie.html');
});
app.post('/', function(req, res) {
var name = req.body.eventname;
console.log(name);
});
http.listen(3000, function(){
console.log('listening on *:3000');
});
Now when I click submit I get an error message which is as follows,
TypeError: Cannot read property 'eventname' of undefined at Object.handle
How do I print the entered name to my console?

Add these lines into your app.js.
require body-parser.
var bodyParser = require('body-parser');
put before your first app.get that will be better.
app.use(bodyParser.json());
app.use(bodyParser.urlencoded());
good luck.

Express doesn't parse request body by default, you will have to use a middleware to do that.
Try this.
var express = require('express');
var app = express()
.use(express.bodyParser());
...

Also, you should read this article . It explains some of the problems (and their solutions) related to common body parsing approach.
