設定パスポート・準急

Question

イムと明示してpassport-localを使用しようとしているが、これは私の設定です：

App.js

var app = express(); 

app.use(require('morgan')('combined')); 
app.use(require('cookie-parser')()); 
app.use(require('body-parser').urlencoded({ extended: true })); 
app.use(require('express-session')({ secret: 'keyboard cat', resave: false, saveUninitialized: false })); 

app.use(passport.initialize()); 
app.use(passport.session()); 

app.use(logger('dev')); 
app.use(bodyParser.json()); 
app.use(bodyParser.urlencoded({ extended: false })); 
app.use(cookieParser()); 
app.use(session({ 
    secret: 'my super secret', 
    resave: false, 
    saveUninitialized: true 
})); 

index.js

var MongoClient = require('mongodb').MongoClient, assert = require('assert'); 
var session = require('express-session'); 
var passport = require('passport'); 
var localPassport = require('passport-local').Strategy; 

var url = 'mongodb://localhost:27017/mydb'; 

var router = express.Router(); 

passport.use(new localPassport(
    function(username, password, cb) { 
    console.log(">>>To evaluate : " + username); 
    console.log(">>>To evaluate : " + password); 
    MongoClient.connect(url, function(err, db) { 
     db.collection('users').find({email: username, password: password, verified: true }, {_id=0, email=1, name = 1}).toArray(function(err, results){ 
     console.log("Fetching results!!!!"); 
     console.log(results); 
     if(results.length >= 1){ 
      console.log("<<<returning true"); 
      return cb(null, results[0]); 
     }else{ 
      console.log("<<<returning 00000"); 
      return cb(null, false); 
     } 
     }); 
    }); 
    } 
)); 

passport.serializeUser(function(user, cb) { 
    cb(null, user.id); 
}); 

passport.deserializeUser(function(id, cb) { 
    db.users.findById(id, function (err, user) { 
    if (err) { return cb(err); } 
    cb(null, user); 
    }); 
}); 


router.get('/invites', function(req, res, next) { 
    require('connect-ensure-login').ensureLoggedIn(), 
    console.log("~~~~~~ ~ ~~~~~ ~~~~~~~~Fetched!"); 
    console.log(req); 
    res.render('invites.html'); 
}); 


router.post('/login', function(req, res, next) { 
    //res.render('invites.html'); 
    //var auth = passport.authenticate('local', { failureRedirect: '/login' }); 
    passport.authenticate('local')(req, res, function() { 
    console.log(">>>Auth: "); 
    console.log(req); 
      res.redirect('/invites'); 
     }); 

}); 

さて、コードの詳細を説明しましょう： コードはprなしで実行されますoblemsと方法：その後、私は方法がOKであることを前提としてい passport.use(new localPassportが正しく呼び出されたが（私は、変数をデバッグ）し、それらのラインは、ターミナル（とない他）に表示されている

console.log("<<<returning true"); 
return cb(null, results[0]); 

結果はOKです。

私が使用しようとしているとき：req.user変数はundefinedです。 ユーザーセッションが要求に格納されていない理由がわかりません。

いくつかのアイデア？

Answer 1

私はついにこれを解決しました。これは非常に素朴なコードですが、例として機能します。

var express = require('express'); 
var passport = require('passport'); 
var Strategy = require('passport-local').Strategy; 

var nodemailer = require('nodemailer'); 
const uuidV1 = require('uuid/v1'); 
var MongoClient = require('mongodb').MongoClient, assert = require('assert'); 
var moment = require('moment'); 
var session = require('express-session'); 
var passport = require('passport'); 
var localPassport = require('passport-local').Strategy; 
var path = require('path'); 

var url = 'mongodb://localhost:27017/viraldb'; 


// Configure the local strategy for use by Passport. 
// 
// The local strategy require a `verify` function which receives the credentials 
// (`username` and `password`) submitted by the user. The function must verify 
// that the password is correct and then invoke `cb` with a user object, which 
// will be set at `req.user` in route handlers after authentication. 
passport.use(new Strategy(
    function(username, password, cb) { 
    username = username.toLowerCase(); 
    MongoClient.connect(url, function(err, db) { 
     db.collection('users').find({email: username, password: password, verified: true }, {_id:0, email: 1, name:1, id: 1}).toArray(function(err, results){ 
     if(results.length >= 1){ 
      return cb(null, results[0]); 
     }else { 
      return cb(null, false); 
     } 
     }); 
    }); 


    })); 



// Configure Passport authenticated session persistence. 
// 
// In order to restore authentication state across HTTP requests, Passport needs 
// to serialize users into and deserialize users out of the session. The 
// typical implementation of this is as simple as supplying the user ID when 
// serializing, and querying the user record by ID from the database when 
// deserializing. 
passport.serializeUser(function(user, cb) { 
    cb(null, user.id); 
}); 

passport.deserializeUser(function(id, cb) { 
    MongoClient.connect(url, function(err, db) { 
    db.collection('users').find({id: id, verified: true }, {_id:0, email: 1, name:1, id: 1}).toArray(function(err, results){ 
     if(results.length >= 1){ 
     return cb(null, results[0]); 
     }else{ 
     return cb(null, false); 
     } 
    }); 
    }); 

}); 




// Create a new Express application. 
var app = express(); 
app.use(express.static(path.join(__dirname, 'public'))); 

// Configure view engine to render EJS templates. 
app.set('views', __dirname + '/views'); 
app.engine('html', require('ejs').renderFile); 
app.set('view engine', 'ejs'); 

// Use application-level middleware for common functionality, including 
// logging, parsing, and session handling. 
app.use(require('morgan')('combined')); 
app.use(require('cookie-parser')()); 
app.use(require('body-parser').urlencoded({ extended: true })); 
app.use(require('express-session')({ secret: 'keyboard cat', resave: false, saveUninitialized: false })); 

// Initialize Passport and restore authentication state, if any, from the 
// session. 
app.use(passport.initialize()); 
app.use(passport.session()); 

// Define routes. 
app.get('/', function(req, res) { 
    res.render('index.html');
