req.user undefined – node + express + passport-facebook

我试图获得护照与我的节点快递服务器一起工作。 我可以用Facebooklogin并在我的数据库中find正确的用户; 但是,当我redirectreq.user总是未定义。 这是我的服务器代码:

 var express = require('express'), path = require('path'), http = require('http'), passport = require('passport'), FacebookStrategy = require('passport-facebook').Strategy, user = require('./routes/users'); var app = express(); passport.use(new FacebookStrategy({ clientID: "HIDDEN", clientSecret: "HIDDEN", callbackURL: "http://MYURL.com/auth/facebook/callback", passReqToCallback: true }, function(req, accessToken, refreshToken, profile, done) { user.findOrCreate(profile, function(err, user) { if (err) { return done(err); } done(null, user); }); } )); passport.serializeUser(function(user, done) { done(null, user._id); }); passport.deserializeUser(function(id, done) { user.findById(id, function(err, user) { done(err, user); }); }); app.configure(function () { app.set('port', process.env.PORT || 3000); app.use(express.static(path.join(__dirname, 'public'))); app.use(express.logger('dev')); /* 'default', 'short', 'tiny', 'dev' */ app.use(express.bodyParser()); app.use(express.cookieParser()); app.use(express.session({ secret: 'foobar' })); app.use(passport.initialize()); app.use(passport.session()); app.use(app.router); }); app.get('/auth/user', function (req, res) { console.log(req); }); app.get('/auth/facebook', passport.authenticate('facebook')); app.get('/auth/facebook/callback', passport.authenticate('facebook', { successRedirect: '/', failureRedirect: '/login' })); http.createServer(app).listen(app.get('port'), function () { console.log("Express server listening on port " + app.get('port')); }); 

我去/ auth / facebook,它find了正确的用户,并redirect到/。 但是,然后我去/ auth /用户和req.user是未定义的,我的会话显示这个:

 cookies: { 'connect.sid': 's:JFdQkihKQQyR4q70q7h2zWFt.VS+te0pT0z/Gtwg7w5B33naCvA/ckKMk60SFenObxUU' }, signedCookies: {}, url: '/auth/user', method: 'GET', sessionStore: { sessions: { '5sk3Txa2vs5sYhvtdYwGaUZx': '{"cookie":{"originalMaxAge":null,"expires":null,"httpOnly":true,"path":"/"},"passport":{"user":"50c527c9c6cb41860b000001"}}', 'Au6m0hAj/3warKOGNSWw0yu2': '{"cookie":{"originalMaxAge":null,"expires":null,"httpOnly":true,"path":"/"},"passport":{}}', JFdQkihKQQyR4q70q7h2zWFt: '{"cookie":{"originalMaxAge":null,"expires":null,"httpOnly":true,"path":"/"},"passport":{}}' }, generate: [Function], _events: { disconnect: [Function], connect: [Function] } }, sessionID: 'JFdQkihKQQyR4q70q7h2zWFt', 

它是否与我的sessionID不匹配护照用户设置的会话有关?

更新

所以我确定sessionID不匹配是因为我在c9.io上运行我的代码,它实际上有两个URL。 当我使用正确的URL并转到/ auth / user时,我的sessionID匹配与passport用户设置的会话,我可以在日志中看到我的deserializeUserfind正确的用户对象。 但是,在此之后, req.user仍然是未定义的。

UPDATE2

我解决了这个问题。 这是在我的user.findByID函数中:

 exports.findById = function(id, callback) { console.log('Trying to find user with id: ' + id); db.collection('users').findOne({'_id':id}, function(err, user) { callback(err, user); }); }; 

变成:

 exports.findById = function(id, callback) { console.log('Trying to find user with id: ' + id); db.collection('users').findOne({'_id':new BSON.ObjectID(id)}, function(err, user) { callback(err, user); }); }; 

       

网上收集的解决方案 "req.user undefined – node + express + passport-facebook"

正如你所说在你更新它是user._idvariables不是在一个有效的格式。 为了避免这种情况,稍后在其他请求和方法中必须处理这种格式,我会build议你在注册时生成一个新的用户ID。

你可以使用这个模块:

节点UUID

 var uuid = require('node-uuid'); function findOrCreate(profile, callback) { // save new profile profile.uid = uuid.v1().replace(/\-/g, ''); }
