facebook-node-sdk for node.js scope parameter? Used this sdk but of to get
parameters required from this?

https://github.com/amachang/facebook-node-sdk decided to use this module
to build my facebook integrated login for node.js following the example
with express:
enter code here
var express = require('express');
var Facebook = require('facebook-node-sdk');
var app = express();
app.configure(function () {
app.use(express.bodyParser());
app.use(express.cookieParser());
app.use(express.session({ secret: 'foo bar' }));
app.use(Facebook.middleware({ appId: '329202683882631',
secret:'1574ab6c7243aeb34c4162e80ca7eb22', scope: 'email', scope:
"user_photos" }));
});
app.get('/', Facebook.loginRequired(), function (req, res) {
req.facebook.api('/me', function(err, user) {
res.writeHead(200, {'Content-Type': 'text/plain'});
res.end('Hello, ' + user.name + user.email+" "+user.photos+'!');
console.log(user);
});
});
