So I am using nodejs and mongodb and trying to set a cookie on one of the pages.

In the app.js file, it is pretty standard using this

var express = require('express')
  , app = express()
  , dbUserModel = require('./models/user')
  , db = require('./db')
  , pass = require('./config/passport')
  , passport = require('passport')
  , routes = require('./routes/index')
  , user = require('./routes/user')
  , path = require('path')
  , http = require('http')
  , connect = require('connect')
  , mongoose = require('mongoose')
  , mongoConnect = mongoose.connect('mongodb://localhost/test5');

// all environments

app.configure(function(){
    app.set('port', process.env.PORT || 3000);
    app.set('views', __dirname + '/views');
    app.set('view engine', 'jade');


    app.use(express.favicon());
    app.use(express.logger('dev'));
    app.use(express.bodyParser());
  app.use(express.cookieParser('secret'));
  ///app.use(express.cookieSession());
  app.use(express.methodOverride());
    app.use(passport.initialize());
    app.use(passport.session());
    app.use(app.router);
    app.use(express.static(path.join(__dirname, 'public')));    
});
  app.get('/', routes.index)
  app.get('/register', user.register);
  app.post('/register', user.registerPost);
  app.get('/registerError', user.registerError);
  app.get('/registerThanks', user.registerThanks);
  app.get('/login', user.login);
  app.post('/login', user.loginPost);
  app.get('/loginError', user.loginError);
  app.get('/userProfile', user.userProfile);

http.createServer(app).listen(app.get('port'), function(){
  console.log('Express server listening on port ' + app.get('port'));
  console.log('Users: ' + db.collections.users);
});

Then I am calling my route file.

This is my code: 

exports.login = function(req, res) {
    res.render('login', {user: req.user, title: 'Weblio'});
};

exports.loginPost = function(req, res, next) {
    passport.authenticate('local', function(err, user, info) {
        if (err) { return next(err) }
        if (!user) { return res.redirect('loginError'); }
        req.logIn(user, function(err) {
            if (err) { return next(err); }
            return res.redirect('userProfile');
        });
  })(req, res, next);
};

exports.loginError = function (req, res) {
    res.render('loginError', {title: 'Weblio'});
};

exports.userProfile = function(req, res) {      
    res.render('userProfile', {user: req.user, title: 'Weblio'});
    res.cookie('name', 'test', { maxAge: 900000, httpOnly: true }); 

};

When I go to the userProfile page and in the console I type in document.cookie it shows an empty string as the result.

I also tried moving the res.cookie into the login post and it was not working...

Please help!

无论您使用哪种编程语言，在将响应标头发送到客户端后，您都无法修改 cookie。当调用res.render()它时，它会与实际视图一起发送标题。

HTTP cookie 是发送到客户端的标头的一部分。

尝试在您向客户端发送响应res.cookie()之前调用。res.render()

此外，在调用时，app.use(express.cookieParser('secret'));您正在创建一个“签名”cookie，方法是提供“秘密”参数。
因此，在更改 cookie 时，您必须告诉 express 您正在处理这样的签名 cookie：
res.cookie('name', 'test', {maxAge: 900000, httpOnly: true, signed: true});
