[英]req.user undefined - node + express + passport-facebook
i'm trying to get passport to work with my node express server. 我试图让护照与我的节点快递服务器一起工作。 I can login in with Facebook and find the correct user in my database;
我可以登录Facebook并在数据库中找到正确的用户; however, when I redirect
req.user
is always undefined. 但是,当我重定向
req.user
始终是未定义的。 Here is my server code: 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'));
});
I go to /auth/facebook, it finds the correct user and redirects me to /. 我转到/ auth / facebook,它找到正确的用户并将我重定向到/。 But then I go to /auth/user and
req.user
is undefined and my sessions show this: 但是然后我转到/ auth / user,
req.user
是未定义的,我的会话显示如下:
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',
Does it have something to do with my sessionID not matching the session where the passport user is set? 它与我的sessionID与设置护照用户的会话不匹配有关吗?
Update 更新资料
So I determined that the sessionID not matching was because I'm running my code on c9.io and it actually has two URLs. 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。 When I use the correct URL and go to /auth/user my sessionID matches the session with passport user set and I can see in the log my deserializeUser finding the correct user object.
当我使用正确的URL并转到/ auth / user时,我的sessionID与具有护照用户集的会话匹配,我可以在日志中看到我的deserializeUser找到正确的用户对象。 However,
req.user
is still undefined after this. 但是,
req.user
仍未定义req.user
。

Update2 更新2
I figured out the problem. 我解决了这个问题。 It was in my user.findByID function:
它在我的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);
});
};
changed to: 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);
});
};
As you said in you update it was the user._id variable not being in a valid format. 如您在更新中所说,这是user._id变量的格式无效。 To avoid this and having to take care of this format later in other requests and methods I will advice you to generate a new user id at signup.
为了避免这种情况,以后在其他请求和方法中必须注意这种格式,我建议您在注册时生成一个新的用户ID。
You can use this module: 您可以使用此模块:
var uuid = require('node-uuid');
function findOrCreate(profile, callback) {
// save new profile
profile.uid = uuid.v1().replace(/\-/g, '');
}
