【问题讨论】：
【参考方案1】：在我看来，您根本没有调用require('./passport.js')(passport)（或任何路径），即。您没有配置护照。我的假设可能得到以下事实的进一步支持：如果您包含来自 passport.js 的代码，您会看到 SyntaxError: Unexpected token ;，因为删除参数和多余的东西，这就是您定义的：
passport.use(new GoogleStrategy(, passport.serializeUser(function(user, done));
passport.deserializeUser(function(id, done) );
function(token, refreshToken, profile, done) );
如果您要学习该教程，您应该查看定义基本应用程序的第一部分。在您的admin.js 中，在require('passport') 行之后添加require('./passport.js')(passport)
【讨论】：
类型错误：护照不是函数【参考方案2】：步骤 1- 在 passport.js 中包含护照包并删除 module.exports 并像在 admin.js 中编写代码一样编写代码
Step 2 - 在 admin.js 中包含这一行
require('./passport.js'); 包含所有软件包之后。
您的 passport.js 将如下所示 -
var GoogleStrategy = require('passport-google-oauth').OAuth2Strategy;
var User = require('../models/users.js');
var configAuth = require('./auth.js');
var passport = require('passport');
passport.use(new GoogleStrategy(
clientID : configAuth.googleAuth.clientID,
clientSecret : configAuth.googleAuth.clientSecret,
callbackURL : configAuth.googleAuth.callbackURL,
,
passport.serializeUser(function(user, done)
done(null, user.id);
);
passport.deserializeUser(function(id, done)
User.findById(id, function(err, user)
done(err, user);
);
);
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.ggoogle.email = profile.emails[0].value;
newUser.save(function(err)
if(err)
throw err;
return done(null, newUser);
);
);
);
));
您的 admin.js 将如下所示 -
(function()
var express, isLoggedIn, passport, router;
express = require('express');
passport = require('passport');
**// include the your passport.js file path
require('./passport.js');**
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', isLoggedIn, 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);
