錯誤：passport.initialize（）中間件未使用什麼命令調用？

Question

我有後續 - 由Visual Studio的節點工具最初產生，使用Express和玉石爲客戶

/** 
* Module dependencies. 
*/ 

var express   = require('express'); 
var fs    = require('fs'); 
var routes   = require('./routes'); 
var user   = require('./routes/user'); 
var http   = require('http'); 
var https   = require('https'); 
var path   = require('path'); 
var passport  = require('passport'); 
var googleStrategy = require('passport-google-oauth').OAuth2Strategy; 
var loginHandler = require('./routes/Login.js'); 
var auth   = require('./config/auth.js'); 
var googleSupport = require('./googleSupport.js'); 

var googleAuthority = auth.googleAuth; 
var googleScopes = ''; 


// retrieve google scopes 
googleScopes = googleSupport.discoverServiceScopes(auth.googleAuth); 

// set up passport 
passport.serializeUser(function (user,done) { 
    done(null, user); 
}); 

passport.deserializeUser(function (obj, done) { 
    done(null, obj); 
}); 

passport.use(new googleStrategy({ 
    clientID: googleAuthority.clientId, 
    clientSecret: googleAuthority.clientSecret, 
    callbackURL: googleAuthority.callbackUrl 
}, 
function (accessToken, refreshToken, profile, done) { 
    return done(null, profile); 
} 
)); 
var request = require('request'); 

var app = express(); 

// all environments 
app.set('port', process.env.PORT || 3000); 
app.set('views', path.join(__dirname, 'views')); 
app.set('view engine', 'jade'); 
app.use(express.favicon()); 
app.use(express.logger('dev')); 
app.use(express.json()); 
app.use(express.urlencoded()); 
app.use(express.methodOverride()); 
app.use(app.router); 
app.use(require('stylus').middleware(path.join(__dirname, 'public'))); 
app.use(express.static(path.join(__dirname, 'public'))); 

// development only 
if ('development' == app.get('env')) { 
    app.use(express.errorHandler()); 
} 

console.log('extracting service scopes'); 

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

app.get('/', routes.index); 
app.get('/index', routes.index); 

// google login support 

// go to login page. 
app.get('/googleLogin', passport.authenticate('google', { scope: [googleScopes] }), 
    function (req, res) { 
     res.redirect('/'); 
    } 
); 

app.get('/AuthorizeGoogle', passport.authenticate('google', { failureRedirect: '/'}), 
    function (req, res) { 
     res.redirect('/'); 
    }); 


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

的事情是，當它驗證用戶得到以下

500 Error: passport.initialize() middleware not in use 
at IncomingMessage.req.login.req.logIn (C:\Node\YourLivesN\YourLivesN\node_modules\passport\lib\http\request.js:44:34)

at IncomingMessage.emit (events.js:129:20) 
at _stream_readable.js:908:16 

現在我認爲這與passport.js passport.initialize() middleware not in use這個問題的原因是一樣的，但是看不到我的代碼中應該有哪些命令。

所以任何人都可以告訴我以什麼順序放置代碼的各個部分。

感謝

嘗試修改此部分

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

到

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

進一步閱讀主題：Difference between app.use and app.get in express.js ，我會建議你在一個獨立的文件中分離護照的配置和需要在需要認證的路徑上。實例教程：https://www.youtube.com/watch?v=zbfet_-Z5UQ&index=12&list=PLZm85UZQLd2Q946FgnllFFMa0mfQLrYDL
