Javascript Can'；无法从everyauth获取自定义用户

我确实读过关于通过everyauth访问当前用户的手册。据说，我可以从以下位置读取当前用户信息：req.user在我的服务器上，everyauth.user和user在我的视图上，但它们没有定义。但如果我尝试从everyauth.twitter或everyauth.facebook等网站获取访问权限，我会从这个社交网络获取用户信息

我想，当从数据库中获取用户（通过社交数据查找或创建）时，它必须保存在会话变量中，如currentUser，我可以在助手和其他数据库请求中获取它

My app.js代码：

var express     = require('express')
  , everyauth   = require('everyauth')
  , Promise     = everyauth.Promise
  , util        = require('util')
  , mongoose    = require('mongoose')
  , routes      = require('./routes')
  , _           = require('underscore')

mongoose.connect('mongodb://127.0.0.1/base');
var Schema = mongoose.Schema
  , ObjectId = Schema.ObjectId;

// Everyauth settings above that app.configure

everyauth.twitter
  .consumerKey('secretKey')
  .consumerSecret('secret')
  .findOrCreateUser(function (session, accessToken, accessTokenSecret, twitterUserData){
      var promise = this.Promise();
      User.findOrCreateByUidAndNetwork(twitterUserData.id, 'twitter', twitterUserData, promise);
      return promise;
  })
  .redirectPath('/')
everyauth.facebook
    .appId("secretId")
    .appSecret("secret")
    .findOrCreateUser( function (session, accessToken, accessTokenExtra, fbUserMetadata) {
      var promise = this.Promise();
      User.findOrCreateByUidAndNetwork(fbUserMetadata.id, 'facebook', fbUserMetadata, promise);
      return promise;
    })
    .redirectPath('/');

var app = module.exports = express.createServer();

// Configuration

app.configure(function(){
  app.set('views', __dirname + '/views');
  app.set('view engine', 'jade');
  app.use(express.bodyParser());
  app.use(express.cookieParser());
  app.use(express.session({secret:'blablabla'}));
  app.use(everyauth.middleware()); // Yes, i'm use it
  app.use(express.methodOverride());
  app.use(app.router); // And it
  app.use(express['static'](__dirname + '/public'));
});

everyauth.helpExpress(app); // And this above that routes

app.dynamicHelpers({
    currentUser: function (req, res){
        return req.user; //it's empty!
    }
})

app.configure('development', function(){
  app.use(express.errorHandler({ dumpExceptions: true, showStack: true })); 
});

app.configure('production', function(){
  app.use(express.errorHandler()); 
});

// Routes

app.get('/', routes.index);
require("./controllers/user");

app.listen(80);

和用户方案：

var Schema = mongoose.Schema
  , ObjectId = Schema.ObjectId;

var UserSchema = new Schema({
    "uid":{type:String},    
    "name":{type:String},   
    "network":{type:String},
    "profile":{}        
});


mongoose.model('User', UserSchema);

var User = mongoose.model('User');

和用户查找或创建功能：

this.findOrCreateByUidAndNetwork = function(uid, network, profile, promise) {
    User.find({uid: uid, network: network}, function(err, users) {
        if(err) throw err;
        if(users.length > 0) {
            promise.fulfill(users[0]);// <-- what i want:)
        } else {
            var user = new User();
            user.network = network;
            user.uid = uid;
            user.profile = profile;
            user.name = profile.first_name || profile.name;
            user.save(function(err) {
                if (err) throw err;
                promise.fulfill(user);
            });
        }
    });
};

this.findOrCreateByUidAndNetwork=函数（uid、网络、配置文件、承诺）{
查找（{uid:uid，network:network}，函数（err，users）{
如果（错误）抛出错误；
如果（users.length>0）{
promise.fulfill（用户[0]）；//可能有点晚，但对于任何需要答案的人来说-

在Everyauth的Github页面上，它指定“要访问用户，请配置Everyauth.everymodule.findUserById”-

everyauth.everymodule
    .findUserById( function (id, callback) {
        yourApi.fetchUserById(id, function (err, user) {
        if (err) return callback(err);
        callback(null, user);
     });
     // or more succinctly, if your api sends a user to the callback with function signature function (err, user):
     // yourApi.fetchUserById(id, callback);
});
