node.js - How to find a session from MongoDB collection using Express and MongoStore -

i implementing session store using node/express/mongo. problem cannot retrieve sessions sessions collection, unable determine whether user has logged in.

i using mongoskin, mongostore, , mongo-connect, although don't mind using mongoose , other tools.

here debug output:

// check whether current user has session. // if so, adds "currentuser" request. // else, redirect login page. function loaduser(req, res, next) {     console.log("loaduser: checking loaduser...");     var db = req.db;     console.log("current req.session.token:");     console.log(req.session.token);     console.log("current req.session:");     console.log(req.session);     if (req.session.token) {         // session id in database 'sessions' collection.         db.collection('sessions').findone({token : req.session.token}, function(err, user) {             console.log("found user looking token:");             console.log(user);             if (user) {                 req.currentuser = user;                 next();             } else {                 console.log("token not in 'sessions', redirecting...");                 res.redirect('/login/webapp_login.html');             }         });     } else {         console.log("no token, redirecting...");         res.redirect('/login/webapp_login.html');     } } 

and here console output:

loaduser: checking loaduser... current req.session._id: 53acb8e1b7b297dc29681def current req.session: { cookie:     { path: '/',      _expires: null,      originalmaxage: null,      httponly: true },   islogged: 21,   username: 'sessiontest1',   token: '57a6dfe0bea9150bd4e2d1f76974e88b', } found user looking token: null token not in 'sessions', redirecting... 

along with:

        db.collection('sessions').find(req.session._id, function(user) { 

i tried:

db.collection('sessions').findone({session:{token:req.session.token}}, function(err, user) { 

but still null , function redirects. missing something? suggestions helpful. using mongoskin, although open solutions in mongoose well.

additionally, know database configured correctly because checked command line:

> db.sessions.find().pretty() {         "_id" : "vnftbgnfvq3s4lhiib_omoxwdu01kfuh",         "session" : "{\"cookie\":{\"originalmaxage\":null,\"expires\":null,\"httponly\":t rue,\"path\":\"/\"},\"islogged\":6}",         "expires" : isodate("2014-07-09t03:44:54.863z") } {         "_id" : "-amkc_kizooan_eqj6rjpvtgwoarglaj",         "session" : "{\"cookie\":{\"originalmaxage\":null,\"expires\":null,\"httponly\":t rue,\"path\":\"/\"},\"islogged\":20,\"username\":\"sessiontest1\",\"token\":\"57a6dfe0bea 9150bd4e2d1f76974e88b\"}",         "expires" : isodate("2014-07-11t06:35:14.835z") } 

what going wrong, , why can't retrieve session sessions collection?

update running

db.collection('sessions').find({"session" : /./}, function(err, user) {

gives me output, believe problem matching record field within session field's string. session field, shown in database output above, problematic because 1 long string , not nested json.

also, sessions records inserted automatically after adding app.js:

app.use(expresssession({     secret: 's3cretc0de',           store: new mongostore({         url: mongourl           }, function () {         console.log("db session connection open");     }) })); 

and added token , username fields within router, shown below:

router.get('/verify', function(req, res) {     req.session.username = username;     req.session.token = req.query.token; } 

am missing something? appreciated.

when use mongostore storing session data don't need query mongodb directly. module you.

you can use req.session session data.

so in routes can like:

app.get('/', function(req, res){   // check if username set in session   if (!req.session.username) {     // redirect login page     res.redirect('/login');   } else {     //   } });  app.post('/login', function(req, res) {     // check check username & password here     // if (username == '...' /&& password ...)      // set username in session session      req.session.username = username;  });
