Session is not correctly obtained from a storage,

问题:

I'm using passport, express-session and connect-pg-simple.

The problem is that session is not correctly obtained from a storage, where it gets properly (i hope, but doubt) saved.

My setup is the same, as in many tutorials, I've found around.

server.js:

import express from 'express';
import next from 'next';
import bodyParser from 'body-parser';
import session from 'express-session';
import connectPgSimple from 'connect-pg-simple';
const sessionStorage = connectPgSimple(session);
import initAuthentication from '!/server/authentication';

const dev = process.env.NODE_ENV !== 'production'; // eslint-disable-line
const port = process.env.PORT || 3000; // eslint-disable-line
const app = next({ dev });

app.prepare()
.then(() => {
  const server = express();

  server.use(express.static('public'));

  /* Note Since version 1.5.0, the cookie-parser middleware no longer needs
     to be used for this module to work. This module now directly reads and writes
     cookies on req/res. Using cookie-parser may result in issues
     if the secret is not the same between this module and cookie-parser.
     https://www.npmjs.com/package/express-session */
  // server.use(cookieParser());

  server.use(bodyParser.json()); // for parsing application/json
  server.use(bodyParser.urlencoded({ extended: true })); // for parsing application/x-www-form-urlencoded
  server.use(session({
    secret: 'keyboard cat',
    store: new sessionStorage(),
    resave: false,
    saveUninitialized: false,
    cookie: {
      secure: false,
      maxAge: 30 * 24 * 60 * 60 * 1000
    }})
  );

  initAuthentication(server);
});

authentication.js:

import passport from 'passport';
import LocalStrategy from 'passport-local';
import bcrypt from 'bcrypt';
import {User} from '!/server/db';
import util from 'util';

User.prototype.validPassword = function(password) {
  return bcrypt.compareSync(password, this.passwordHash);
};

User.authenticate = (username, password, done) => {
  User.findOne({where: {nickname: username}}).then(user => {
    if (!user) {
      return done(null, false, { message: 'Неверное имя пользователя.' });
    }
    if (!user.validPassword(password)) {
      return done(null, false, { message: 'Неверный пароль.' });
    }
    return done(null, user);
  }).catch(err => {
    return done(err);
  });
};

export default function initAuthentication(server) {
  server.use(passport.initialize());
  server.use(passport.session());

  passport.use('local-signIn', new LocalStrategy(User.authenticate));

  passport.serializeUser((user, done) => {
    console.log('> serializeUser "'+user.nickname+'" ('+user.id+')');
    done(null, user.id);
  });
  passport.deserializeUser((id, done) => {
    console.log('> deserializeUser with id: ' + id)
    User.findById(id).then(user => {
      done(null, user);
    }).catch(error => {
      console.log('Error in passport.deserializeUser: ' + error);
      done(error, null);
    });
  });

  server.post('/user/login',
    passport.authenticate('local-signIn'),
    (req, res) => {
      // If this function gets called, authentication was successful.
      // `req.user` contains the authenticated user.
      console.log('Authenticated user "'+req.user.nickname+'"');
      req.login(req.user, (err)=> {
        if (err) console.log(err);
        console.log('\t Session established for user "'+req.user.nickname+'"');
        res.json(req.user);
      });
    }
  );

  function logAuthenticationStatus(req, res, next) {
    console.log('Authentication status:')
    console.log('\treq.cookies: ' + util.inspect(req.cookies));
    console.log('\treq.isAuthenticated: ', req.isAuthenticated());
    console.log('\treq.session: ', req.session);
    if (req.user) {
      console.log('\tLogged in as "'+req.user.nickname+'"');
    } else {
      console.log('\tNot logged in');
    }
    next();
  }

  server.use(logAuthenticationStatus);

  server.get('/logout', function(req, res){
    req.logout();
    res.redirect('/');
  });
}

The interesting part is debug output of 'express-session', thanks to amazing npm-package debug.

So, when a request to /user/login comes, with username=AntonAL, following happens:

Executing (default): SELECT "id", "nickname", "email", "password", "passwordHash", "lastLoggedIn", "createdAt", "updatedAt" FROM "users" AS "user" WHERE "user"."nickname" = 'AntonAL' LIMIT 1;
> serializeUser "AntonAL" (1)
Authenticated user "AntonAL"
> serializeUser "AntonAL" (1)
     Session established for user "AntonAL"

So, session is saved in db, let's check it:

SELECT * FROM session WHERE sid='qiQfhyAvDDPD7muJLtGdZudKqMug0aAC';`

sid                |                                                                     sess                                                                      |       expire

So far, so good.

Now, I'm requesting a home page of a website and getting following:

         httpOnly: true,
         secure: false } }

I see, that 'express-session' tries to fetch session with another SID O6rS2cPlQ6JDaUUxxYRAg-VI5MmldaRE, that does't exist in database.

Why it happens?

AFAIK, it should fetch by SID = qiQfhyAvDDPD7muJLtGdZudKqMug0aAC…

What issues can be with my setup?

One secret key, 'cookie-parser' is not used, according to recomentation 'Note Since version 1.5.0, the cookie-parser middleware no longer needs'…

I'm completely stuck with this.

Please, help.

Something is wrong with sid generation

When I manually change stored session's sid to make it match to what express-session is requesting,

UPDATE session SET sid='O6rS2cPlQ6JDaUUxxYRAg-VI5MmldaRE' WHERE sid='qiQfhyAvDDPD7muJLtGdZudKqMug0aAC';

session is fetched correctly and user is persisted:

  express-session session found +2ms

     httpOnly: true,
     secure: false },

So, now it's clear – sid parameter is different, when generating session and fetching it.

回答1:

Figured it out.

In client code, I was using fetch function with following code:

fetch('/user/login', {
  method: 'POST',
  headers: {
    'Content-Type': 'application/json',
  },
  body: JSON.stringify(values)
});

This approach gave me the problem in question.

When I changed request method to 'GET' in routes and used plain redirect, everything I got it to work.

window.location.href = "/login?"+querystring.stringify(values);

Why this happens?
