Passport-init.js身份驗證在nodejs中不起作用

Question

我是nodejs的新手，嘗試開發nodejs演示應用程序this article。我遵循了所有步驟 ，其第一階段對我來說工作得很好。但添加Passport身份驗證後，它不工作

這裏是我的app.js

var express = require('express'); 
var path = require('path'); 
var favicon = require('serve-favicon'); 
var logger = require('morgan'); 
var cookieParser = require('cookie-parser'); 
var bodyParser = require('body-parser'); 
var session = require('express-session'); 
var passport = require('passport'); 
//add for Mongo support 
//var mongoose = require('mongoose'); 


var api = require('./routes/api'); 
var authenticate = require('./routes/authenticate')(passport); 

//connect to Mongo 
// mongoose.connect('mongodb://localhost:27017/MEAN_Stack'); 
// require('./models/models.js'); 

var app = express(); 

// view engine setup 
app.set('views', path.join(__dirname, 'views')); 
app.set('view engine', 'ejs'); 

// uncomment after placing your favicon in /public 
//app.use(favicon(path.join(__dirname, 'public', 'favicon.ico'))); 
app.use(logger('dev')); 
app.use(session({ 
    secret: 'keyboard cat' 
})); 
//app.use(bodyParser.json()); 
//app.use(bodyParser.urlencoded({ extended: false })); 
app.use(cookieParser()); 
app.use(express.static(path.join(__dirname, 'public'))); 
app.use(passport.initialize()); 
app.use(passport.session()); 


//// Initialize Passport 
var initPassport = require('./passport-init'); 
initPassport(passport); 

app.use('/api', api); 
app.use('/auth', authenticate); 

// catch 404 and forward to error handler 
app.use(function(req, res, next) { 
    var err = new Error('Not Found'); 
    err.status = 404; 
    next(err); 
}); 

// error handlers 

// development error handler 
// will print stacktrace 
if (app.get('env') === 'development') { 
    app.use(function(err, req, res, next) { 
    res.status(err.status || 500); 
    res.render('error', { 
     message: err.message, 
     error: err 
    }); 
    }); 
} 

// production error handler 
// no stacktraces leaked to user 
app.use(function(err, req, res, next) { 
    res.status(err.status || 500); 
    res.render('error', { 
    message: err.message, 
    error: {} 
    }); 
}); 


module.exports = app; 

這裏是我的api.js

var express = require('express'); 
var router = express.Router(); 


//Register the authentication middleware 
//router.use('/posts'); 

//api for all posts 
router.route('/posts') 

    //create a new post 
    .post(function(req, res){ 

     //TODO create a new post in the database 
     res.send({message:"TODO create a new post in the database rhushikesh"}); 
    }) 

    .get(function(req, res){ 

     //TODO get all the posts in the database 
     res.send({message:"TODO get all the posts in the database"}); 
    }) 

//api for a specfic post 
router.route('/posts/:id') 

    //create 
    .put(function(req,res){ 
     return res.send({message:'TODO modify an existing post by using param ' + req.param.id}); 
    }) 

    .get(function(req,res){ 
     return res.send({message:'TODO get an existing post by using param ' + req.param.id}); 
    }) 

    .delete(function(req,res){ 
     return res.send({message:'TODO delete an existing post by using param ' + req.param.id}) 
    }); 

module.exports = router; 

這裏是我的authenticate.js

var express = require('express'); 
var router = express.Router(); 

module.exports = function(passport){ 

    //sends successful login state back to angular 
    router.get('/success', function(req, res){ 
     res.send({state: 'success', user: req.user ? req.user : null}); 
    }); 

    //sends failure login state back to angular 
    router.get('/failure', function(req, res){ 
     res.send({state: 'failure', user: null, message: "Invalid username or password1111"}); 
    }); 

    //log in 
    router.post('/login', passport.authenticate('login', { 
     successRedirect: '/auth/success', 
     failureRedirect: '/auth/failure' 
    })); 

    //sign up 
    router.post('/signup', passport.authenticate('signup', { 
     successRedirect: '/auth/success', 
     failureRedirect: '/auth/failure' 
    })); 

    //log out 
    router.get('/signout', function(req, res) { 
     req.logout(); 
     res.redirect('/'); 
    }); 

    return router; 

} 

這是我的passport-init.js

var LocalStrategy = require('passport-local').Strategy; 
var bCrypt = require('bcrypt-nodejs'); 
//temporary data store 
var users = {}; 
module.exports = function(passport){ 

    // Passport needs to be able to serialize and deserialize users to support persistent login sessions 
    passport.serializeUser(function(user, done) { 
     console.log('serializing user:',user.username); 
     return done(null, user.username); 
    }); 

    passport.deserializeUser(function(username, done) { 

     return done('we have not implemented this', false); 

    }); 

    passport.use('login', new LocalStrategy({ 
      passReqToCallback : true 
     }, 
     function(req, username, password, done) { 

      if(!users[username]){ 
       console.log('User Not Found with username '+username); 
       return done(null, false); 
      } 

      if(isValidPassword(users[username], password)){ 
       //sucessfully authenticated 
       return done(null, users[username]); 
      } 
      else{ 
       console.log('Invalid password '+username); 
       return done(null, false) 
      } 
     } 
    )); 

    passport.use('signup', new LocalStrategy({ 
      passReqToCallback : true // allows us to pass back the entire request to the callback 
     }, 
     function(req, username, password, done) { 

     // if (users[username]){ 
     //   console.log('User already exists with username: ' + username); 
     //   return done(null, false); 
     //  } 

      //store user in memory 
      users[username] = { 
       username: username, 
       password: createHash(password) 
      } 

      console.log(users[username].username + ' Registration successful'); 
      return done(null, users[username]); 

     }) 
    ); 

    var isValidPassword = function(user, password){ 
     return bCrypt.compareSync(password, user.password); 
    }; 
    // Generates hash using bCrypt 
    var createHash = function(password){ 
     return bCrypt.hashSync(password, bCrypt.genSaltSync(10), null); 
    }; 

}; 

當我嘗試點擊郵遞員註冊api時，它總是重定向到失敗api。我也試過用調試器，但我沒有得到那裏的控制器。

只是取消註釋以下在app.js

//app.use(bodyParser.json()); 
//app.use(bodyParser.urlencoded({ extended: false })); 

和更新線路護照init.js

passport.deserializeUser(function(username, done) { 

     return done('we have not implemented this', false); 

    }); 

到

passport.deserializeUser(function(username, done) { 

     return done(null, users[username]); 

    });
