How can I fix authentication function in passport.js - node.js

Question

I want to make authentication function with Passport.js+Express.
But If I run this code, I receive failure result and null in 'req.user'.
I want to find the problem, but console.log() in localStrategy is not called when I was using passport.authenticate(). I don't know where I have to fix.
How can I fix this code to get proper function?
-app.js
var express = require('express');
var bodyparser=require('body-parser');
var path = require('path');
var cookieParser = require('cookie-parser');
var passport = require('passport'); //passport module add
var localStrategy = require('passport-local').Strategy;
var cookieSession=require('cookie-session');
var index = require('./index.js');
var app=express();
app.use(cookieParser());
app.use(express.static(__dirname+'/views'));
app.use(cookieSession({
keys : ['login'],
cookie : {maxAge:1000*60*60}
}));
app.set('views',__dirname+'/views');
app.set('view engine','html');
app.engine('html',require('ejs').renderFile);
app.use('/',index);
app.listen(8000,function(){
console.log('server started');
});
module.exports=app;

You should check the "req" param inside
function(req,username,password,done)
may be this function takes only three parameters
**http://www.passportjs.org/packages/passport-local/**
you should check what you get on post request through this `req` using this function
