Parse / Node.js，用户会话管理（javascript sdk）。(Parse / Node.js, user session management (javascript sdk). Parse.User.current() won't persist)

 我试图在自我托管的node.js服务器中使用parseExpressCookieSession模块，该服务器在服务器端使用parse javascript SDK模块。 我按照这里找到的说明设置服务器，以自动将用户会话保存在Parse.User.current（）对象中。 
 
 但是，在成功登录后向Node.js服务器发出新请求时，Parse.User.current（）对象始终为空。 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 } }));

I'm attempting to use the parseExpressCookieSession module within my self-hosted node.js server that uses the parse javascript SDK module on the server-side. I'm following the instructions found here to set up the server to automatically persist user sessions in the Parse.User.current() object.
 
However, the Parse.User.current() object is always null on making new requests to the node.js server after a successful login. Attached is the set up code for my server.js file.
 
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 } }));
