護照-Facebook返回'undefined'個人資料對象

我在我的應用程序中實施passport-facebook身份驗證。我已經實現了下面的代碼。護照-Facebook返回'undefined'個人資料對象

routes.js

// route for facebook authentication and login 
router.get('/facebook', passport.authenticate('facebook', { scope : ['email'] })); 

// handle the callback after facebook has authenticated the user 
router.get('/facebook/callback', passport.authenticate('facebook', { successRedirect : '/dashboard', failureRedirect : '/'}));

passport.js

passport.use(new FacebookStrategy({ 
    clientID  : config.facebookAuth.clientID, 
    clientSecret : config.facebookAuth.clientSecret, 
    callbackURL  : config.facebookAuth.callbackURL, 
    passReqToCallback : true, 
    profileFields: ['id', 'emails', 'name'] 
}, 
function(token, refreshToken, profile, done){ 
    process.nextTick(function(){ 
     console.log(profile); 
     User.findOne({ 'username' : profile.name.givenName }, function(err, user){ 
      if (err) 
       return done(err); // user not found 
      if (user) { 
       return done(null, user); // user found, return that user 
      }else{ 
       var newUser = new User(); 
       newUser.username = profile.name.givenName; 
       newUser.email = profile.emails[0].value; 
       newUser.token = token; 
       newUser.password = ""; 

       // save user to the database 
       newUser.save(function(err) { 
        if (err) 
         throw err; 
        // if successful, return the new user 
        return done(null, newUser); 
       }); 
      } 
     }); 
    }); 
}));

登錄按鈕

   <a name="facebookLogin" class="btn btn-block btn-lg" href="https://vote-center.herokuapp.com/users/facebook" role="button"><span><img src="images/facebook.png"></span></a>

了Facebook戰略的回調函數，我總是得到輪廓爲未定義和所以錯誤在運行時拋出。我哪裏錯了？

以下是供參考的日誌。

我發現我犯的錯誤。這是在Facebook開發者網站上的應用程序註冊。 Facebook希望在註冊時瞭解域名和網站URL。我以前沒有填寫過這些信息。一旦我填補了這個問題，問題就解決了。
