如何使用护照举行会议？

Question

因此，我希望我的用户会话在登录/注册时保持不变，但它没有。

官方文档说要从以下几点开始：

  app.use(express.session({ secret: 'keyboard cat' }));
  app.use(passport.initialize());
  app.use(passport.session());

我做了。然后它继续指定：

passport.serializeUser(function(user, done) {
  console.log("serialize user: ", user);
  done(null, user[0]._id);
});

passport.deserializeUser(function(id, done) {
  User.findById(id, function(err, user) {
    done(err, user);
  });
});

res.cookie('userid', user.id, { maxAge: 2592000000 });

//npm modules
const express = require('express');
const uuid = require('uuid/v4')
const session = require('express-session')
const FileStore = require('session-file-store')(session);
const bodyParser = require('body-parser');
const passport = require('passport');
const LocalStrategy = require('passport-local').Strategy;

const users = [
  {id: '2f24vvg', email: '[e-mail]', password: 'password'}
]

// configure passport.js to use the local strategy
passport.use(new LocalStrategy(
  { usernameField: 'email' },
  (email, password, done) => {
    console.log('Inside local strategy callback')
    // here is where you make a call to the database
    // to find the user based on their username or email address
    // for now, we'll just pretend we found that it was users[0]
    const user = users[0] 
    if(email === user.email && password === user.password) {
      console.log('Local strategy returned true')
      return done(null, user)
    }
  }
));

// tell passport how to serialize the user
passport.serializeUser((user, done) => {
  console.log('Inside serializeUser callback. User id is save to the session file store here')
  done(null, user.id);
});

// create the server
const app = express();

// add & configure middleware
app.use(bodyParser.urlencoded({ extended: false }))
app.use(bodyParser.json())
app.use(session({
  genid: (req) => {
    console.log('Inside session middleware genid function')
    console.log(`Request object sessionID from client: ${req.sessionID}`)
    return uuid() // use UUIDs for session IDs
  },
  store: new FileStore(),
  secret: 'keyboard cat',
  resave: false,
  saveUninitialized: true
}))
app.use(passport.initialize());
app.use(passport.session());

// create the homepage route at '/'
app.get('/', (req, res) => {
  console.log('Inside the homepage callback')
  console.log(req.sessionID)
  res.send(`You got home page!\n`)
})

// create the login get and post routes
app.get('/login', (req, res) => {
  console.log('Inside GET /login callback')
  console.log(req.sessionID)
  res.send(`You got the login page!\n`)
})

app.post('/login', (req, res, next) => {
  console.log('Inside POST /login callback')
  passport.authenticate('local', (err, user, info) => {
    console.log('Inside passport.authenticate() callback');
    console.log(`req.session.passport: ${JSON.stringify(req.session.passport)}`)
    console.log(`req.user: ${JSON.stringify(req.user)}`)
    req.login(user, (err) => {
      console.log('Inside req.login() callback')
      console.log(`req.session.passport: ${JSON.stringify(req.session.passport)}`)
      console.log(`req.user: ${JSON.stringify(req.user)}`)
      return res.send('You were authenticated & logged in!\n');
    })
  })(req, res, next);
})

// tell the server what port to listen on
app.listen(3000, () => {
  console.log('Listening on localhost:3000')
})
