Access Session Object In Express Middleware

This is my Express middleware stack: var server = express() .use(express.cookieParser()) .use(express.session({secret: 'Secret'})) .use(express.bodyParser()) .use(f

Solution 1:

This program works fine. Before I access /setSession, the middleware prints after session: undefined. Once I GET /setSession, it prints after session: admin. As long as the browser you are testing with (not curl) stores and sends the session cookies, this will work as expected.

var express = require('express');
var server = express();
server.use(express.cookieParser());
server.use(express.session({secret: 'SEKRET'}));
server.use(function (q,r,n) {console.log('after session:', q.session.user);n();});
server.get('/', function (q,r,n) {r.send("you got slashed");});
server.get('/setSession', function (req, res) {
  console.log("logging admin in via /setSession");
  req.session.user = 'admin';
  res.send("admin logged in");
});
server.listen(3000);

Solution 2:

There must be something wrong with your settings. The following example, that is very similar to your code but uses GET instead POST, works fine for me

app.configure(function(){
  // ...
  app.use(express.cookieParser('your secret here'));
  app.use(express.session());

  app.use(function(req, res, next) {
    console.log(req.session.user + ' from middleware');
    next();
  });

  app.use(app.router);
  app.use(express.static(path.join(__dirname, 'public')));
});

and

app.get('/getSession', function(req, res) {
  console.log(req.session.user);
  res.send('awesome');
});

app.get('/setSession', function(req, res) {
  req.session.user = 'admin';
  res.send('done');
});

Now when you do the following everything works as expected

1. GET /getSession => undefined from middleware, undefined
2. GET /setSession => undefined from middleware
3. GET /getSession => admin from middleware, admin
