当我使用google登录时，我发现它使用google verifyCallback，但它首先使用facebook进行序列化和反序列化，然后使用gooogle的serializeUser和deserializeUser方法：

User exists in google verify callback

Deserializing facebook user
null

我发现每个应用程序只能定义一次序列化和反序列化，每个机制都应该使用它来维护用户

这是我的序列化/反序列化代码：

 var facebook = require('./facebook');
var google = require('./google');
var basic = {
    login:require('./basic/login'),
    signup:require('./basic/signup')
};

var twitter = require('./twitter');
var dropbox = require('./dropbox');

var User = require('../models/user');

module.exports = function(passport,config){
    var serializeCallback = function serializeCallback(user,done){
        console.log("Serializing user");
        console.log(user);
        done(null, user.id);
    };

    var deserializeCallback = function deserializeCallback(id,done){
        console.log("Deserializing user");
        console.log(id);

        var findUser = function findUser(err,user){
          if(err)
            console.log("An  error occured while deserializing user");
          else
             console.log(user);
          done(err,user);
        }

        User.findById(id,findUser);
    };

    passport.serializeUser(serializeCallback);
    passport.deserializeUser(deserializeCallback);
    /*Tested google and facebook successfully*/
    if(config.basic)
    {   
        basic.login(passport);
        basic.signup(passport);
    }   
    if(config.facebook)
        facebook(passport);
    if(config.google)
        google(passport);
    if(config.twitter)
        twitter(passport);
    if(config.dropbox)
        dropbox(passport);
}

每个提供商都设置在如下文件夹中（以facebook为例）：
