我正在尝试使用护照在帆中实现facebook连接.因此,我在我的services文件夹中创建了一个passport.js文件,代码如下.看起来登录成功完成,但是用户序列化似乎不起作用我放在它的console.log永远不会出现在控制台中,一旦用户被认为我无法访问用户id trhough req.user登录.有没有人设法让护照与帆一起工作？

var  passport = require('passport'),FacebookStrategy = require('passport-facebook').Strategy,bcrypt      = require('bcrypt');

// helper functions
function findById(id,fn) {
  User.findOne(id).done( function(err,user){
    if (err){
      return fn(null,null);
    }else{
      return fn(null,user);
    }
  });
}

function findByUsername(u,fn) {
  User.findOne({
    username: u
  }).done(function(err,user) {
    // Error handling
    if (err) {
      return fn(null,null);
    // The User was found successfully!
    }else{
      return fn(null,user);
    }
  });
}

// Passport session setup.
// To support persistent login sessions,Passport needs to be able to
// serialize users into and deserialize users out of the session. Typically,// this will be as simple as storing the user ID when serializing,and finding
// the user by ID when deserializing.
passport.serializeUser(function(user,done) {
  console.log("utilisateur serilizé!");
  done(null,user.uid);
});

passport.deserializeUser(function(id,done) {
  //console.log("coucou");
  findById(id,function (err,user) {
    done(err,user);
  });
});


// Use the LocalStrategy within Passport.
// Strategies in passport require a `verify` function,which accept
// credentials (in this case,a username and password),and invoke a callback
// with a user object.


// using https://gist.github.com/theangryangel/5060446
// as an example


passport.use(new FacebookStrategy({
    clientID: 'XXX',clientSecret: 'XXX',callbackURL: "http://localhost:1337/callback"
  },function(accessToken,refreshToken,profile,done) {
    User.findOne({uid: profile.id},function(err,user) {
      if (err) { return done(err); }
      if (user) {
        //console.log('momo');
        User.update({uid : user.uid},{token : accessToken},function(){done(null,user);});
         } else {
        console.log(profile);
        var user_data = {
          token : accessToken,provider:   profile.provider,alias:  profile.username,uid:      profile.id,created:  new Date().getTime(),name: {
            first:  profile.name.givenName,last: profile.name.familyName
          },alerts: {
              email:      true,mobile:   false,features: true
          }
        };
        console.log(user_data);
        User.create(user_data).done(function(err,user) {
          console.log(err);
          if(err) { console.log("err");throw err; }
          done(null,user);
        });
      }
    });
  }
));
