When the two modules Socket. io and Express in Node. js are integrated, the following error occurs:

var express = require('express');var app = module.exports = express.createServer(),    io = require('socket.io').listen(app); app.listen(3000); app.get('/', function(req, res){    res.sendfile(__dirname + '/index.html');}); io.sockets.on('connection', function(socket){    socket.emit('welcome', {text: 'OH HAI! U R CONNECTED!'});});

Error cause:

The main cause of the error is that the above Code is 8th lines. You can simply change the code to the following format.

var express = require('express');var app = module.exports = express.createServer(),    io = require('socket.io').listen(app);app.listen(3000);app.get('/', function(req, res){res.sendfile('/index.html', {root: __dirname});});io.sockets.on('connection', function(socket){socket.emit('welcome', {text: 'OH HAI! U R CONNECTED'});});

Upload under win

_ Dirname + '/index.html'-> E: \ nodejs \ demo/index.html

It seems that the url parsing module is used there. The final parsing result is not like the path in windows ..

The path is incorrect when the stream is created ..
