Parse / Node.js,用户会话管理(javascript sdk). Parse.User.current()不会持久化

我正在尝试在我自己托管的node.js服务器中使用parseExpressCookieSession模块,该服务器使用服务器端的解析 javascript SDK模块.我按照此处的说明设置服务器以自动保留Parse.User.current()对象中的用户会话.

但是,Parse.User.current()对象在成功登录后向node.js服务器发出新请求时始终为null.附件是我的server.js文件的设置代码.

server.js：

var express  = require('express');
var app      = express();                               // create our app w/ express
var morgan = require('morgan');             // log requests to the console (express4)
var bodyParser = require('body-parser');    // pull information from HTML POST (express4)
var methodOverride = require('method-override'); // simulate deletE and PUT (express4)
var logger = require('./logger');
var api = require('./api.js');
var config = require('./config');
GLOBAl.Parse = require('parse').Parse;
Parse.initialize(config.parse.appID,config.parse.jsKey);
var cookieParser = require('cookie-parser');
var parseExpresshttpsRedirect = require('parse-express-https-redirect');
var parseExpressCookieSession = require('parse-express-cookie-session');

// configuration =================
app.use(parseExpresshttpsRedirect());
app.use(express.static(__dirname + '/public'));    
app.use(morgan("dev",{ "stream": logger.stream }));
app.use(bodyParser.urlencoded({'extended':'true'}));
app.use(bodyParser.json());
app.use(bodyParser.json({ type: 'application/vnd.api+json' }));
app.use(methodOverride());
app.use(cookieParser(config.parse.jsKey));
app.use(parseExpressCookieSession({ cookie: { maxAge: 3600000 } }));

var cookieParser = require('cookie-parser');
var cookieSession = require('cookie-session');

app.use(cookieSession({
  name: COOKIE_NAME,secret: COOKIE_SECRET,maxAge: 15724800000
}));

app.use(cookieParser(COOKIE_SECRET));

Parse.User.logIn(username,password,{
      success: function(user) {
        console.log(user);
        req.session.token = user._sessionToken;
        res.sendStatus(200);
      },error: function(user,error) {
        res.status(400).send(error);
      }
    });

Parse.User.become(req.session.token ? req.session.token : "NoTokenFound").then(function (user) {
      // Do something Now that we have a Parse.User stored in the "user" var
    },function (error) {
      console.log(error);
      res.sendStatus(200);
    });
