passport-facebook returns 'undefined' 个人资料对象

Question

我正在我的应用程序中实施 passport-facebook 身份验证。我已经实现了以下代码。

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);
                });
            }
        });
    });
}));

登录按钮

                <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>

在 facebook 策略的回调函数中，我总是得到未定义的配置文件，因此在运行时抛出错误。我哪里错了？

Answer 1

我发现了我犯的错误。它与 Facebook 开发者网站上的应用程序注册有关。 Facebook 希望自己在注册时知道域和站点 URL。我以前没有填写过这些信息。一旦我填好，问题就解决了。
