节点不能调用未定义的方法'serializeUser'

我使用Passport与Googlebuild立authentication系统。 我正在学习这个教程。 但是，在我的passport.js文件中，我一直得到这个错误：

D:\Programming\weebly-site\config\passport.js:11 passport.serializeUser(function(user, done){ ^ TypeError: Cannot call method 'serializeUser' of undefined at module.exports (D:\Programming\weebly-site\config\passport.js:11:11) at Object.<anonymous> (D:\Programming\weebly-site\routes\admin.js:9:46) at Object.<anonymous> (D:\Programming\weebly-site\routes\admin.js:39:4) at Module._compile (module.js:456:26) at Object.Module._extensions..js (module.js:474:10) at Module.load (module.js:356:32) at Function.Module._load (module.js:312:12) at Module.require (module.js:364:17) at require (module.js:380:17) at Object.<anonymous> (D:\Programming\weebly-site\app.js:18:19) at Module._compile (module.js:456:26) at Object.Module._extensions..js (module.js:474:10) at Module.load (module.js:356:32) at Function.Module._load (module.js:312:12) at Module.require (module.js:364:17) at require (module.js:380:17) at Object.<anonymous> (D:\Programming\weebly-site\bin\www:3:11) at Module._compile (module.js:456:26) at Object.Module._extensions..js (module.js:474:10) at Module.load (module.js:356:32) at Function.Module._load (module.js:312:12) at Function.Module.runMain (module.js:497:10) at startup (node.js:119:16) at node.js:906:3 

这是我的passport.js文件：

 var GoogleStrategy = require('passport-google-oauth').OAuth2Strategy; var User = require('../models/users.js'); var configAuth = require('./auth.js'); module.exports = function(passport) { passport.serializeUser(function(user, done){ done(null, user.id); }); passport.deserializeUser(function(id, done) { User.findById(id, function(err, user) { done(err, user); }); }); passport.use(new GoogleStrategy({ clientID : configAuth.googleAuth.clientID, clientSecret : configAuth.googleAuth.clientSecret, callbackURL : configAuth.googleAuth.callbackURL, }, function(token, refreshToken, profile, done) { process.nextTick(function() { User.findOne({ 'google.id' : profile.id}, function(err, user) { if(err) return done(err); if(user) { return done(null, user); } else { var newUser = new User(); newUser.google.id = profile.id; newUser.google.token = token; newUser.google.name = profile.displayName; newUser.google.email = profile.emails[0].value; newUser.save(function(err){ if(err) throw err; return done(null, newUser); }); } }); }); })); }; 

App.js文件：

 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 coffeeScript = require('coffee-script'); var mongoose = require('mongoose'); var passport = require('passport'); var flash = require('connect-flash'); var session = require('express-session'); var configDB = require('./config/database.js'); mongoose.connect(configDB.url); require('./config/passport.js')(passport); var routes = require('./routes/index'); var adminRoutes = require('./routes/admin') var users = require('./routes/users'); var app = express(); app.use('/', routes); app.use('/admin',adminRoutes); app.use('/users', users); .... app.use(session({secret: 'lotsofwords', saveUninitialized: true, resave: true})); app.use(passport.initialize()); app.use(passport.session()); .... module.exports = app; 

Admin.js

 // Generated by CoffeeScript 1.8.0 (function() { var express, isLoggedIn, pasport, passport, router; express = require('express'); passport = require('passport'); require('../config/passport.js')(passport); router = express.Router(); isLoggedIn = function(req, res, next) { if (req.isAuthenticated()) { return next(); } res.redirect("/admin"); }; router.get('/', function(req, res) { return res.render('admin/admin_index.jade'); }); router.get('/editor', function(req, res) { return res.render('admin/admin_editor.jade'); }); router.get('/auth/google', passport.authenticate('google', { scope: ['profile', 'email'] })); router.get('/auth/google/callback', passport.authenticate('google', { successRedirect: '/editor', failureRedirect: '/' })); module.exports = router; }).call(this); 

我不知道如何解决这个问题 – 我search了SO和谷歌无济于事。 任何帮助将不胜感激，谢谢！

Answer 1

您正在查看错误的文件。 错误在D:\Programming\weebly-site\routes\admin.js:9:46 。 您正在调用config/passport.js导出的函数，而不传入护照模块。

Answer 2

你在哪里放置了要求声明？ require（'./ config / passport'）（ passport ）;

注意加粗的护照。

你是否在上面或下面build立护照variables？

这工作：

1. var passport = require（'passport'）;
2. 要求（ './configuration/护照'）（护照）; / /通过护照configuration

其他（这失败）：

1. 要求（ './configuration/护照'）（护照）; / /通过护照configuration
2. var passport = require（'passport'）;
