Question

我正在尝试在gcloud上运行我的nodejs应用程序，并且快速会话未按预期工作。它在我当地的开发中工作正常。

app.js

var express = require('express');

var path = require('path');
var favicon = require('serve-favicon');
var logger = require('morgan');
var cookieParser = require('cookie-parser');
var bodyParser = require('body-parser');
var session = require('express-session');

// var http = require('http');
// var reload = require('reload');


var index = require('./routes/index');
var users = require('./routes/users');
var user = require('./routes/user');
var dashboard = require('./routes/dashboard');
var search = require('./routes/search');
var profile = require('./routes/profile');
var ajax = require('./routes/admin-ajax');
var logout = require('./routes/logout');
var administrator = require('./routes/administrator');



var app = express();




app.set('port', process.env.PORT || 3000);

// view engine setup
app.set('views', path.join(__dirname, 'views'));
app.set('view engine', 'pug');

app.use(cookieParser('mysessionsecretkey'));


// uncomment after placing your favicon in /public
//app.use(favicon(path.join(__dirname, 'public', 'favicon.ico')));
app.use(logger('dev'));
app.use(bodyParser.json());
app.use(bodyParser.urlencoded({ extended: false }));
app.use(express.static(path.join(__dirname, 'public')));


app.set('trust proxy', 1) // trust first proxy
app.use(session({
  secret: 'mysessionsecretkey',
  resave: false,
  saveUninitialized: true,
  cookie:{
    secure:true,
    maxAge: 864000000 
  }
}))


app.use('/js', express.static(__dirname + '/node_modules/bootstrap/dist/js')); // redirect bootstrap JS
app.use('/js', express.static(__dirname + '/node_modules/jquery/dist')); // redirect JS jQuery
app.use('/js', express.static(__dirname + '/node_modules/jquery-ui-dist')); // redirect JS jQuery
app.use('/js', express.static(__dirname + '/node_modules/popper.js/dist/umd')); 
app.use('/js', express.static(__dirname + '/node_modules/moment/min')); 
app.use('/js', express.static(__dirname + '/node_modules/lodash')); 
app.use('/css', express.static(__dirname + '/node_modules/jquery-ui-dist')); // redirect JS jQuery
app.use('/css', express.static(__dirname + '/node_modules/bootstrap/dist/css')); // redirect CSS bootstrap
app.use('/css', express.static(__dirname + '/node_modules/font-awesome/css')); 
app.use('/css', express.static(__dirname + '/node_modules/animate.css')); 
app.use('/js', express.static(__dirname + '/node_modules/datatables.net/js')); 
app.use('/js', express.static(__dirname + '/node_modules/datatables.net-bs4/js')); 
app.use('/css', express.static(__dirname + '/node_modules/datatables.net-bs4/css')); 




app.use('/', index);
app.use('/users', users);
app.use('/user', user);
app.use('/dashboard', dashboard);
app.use('/search', search);
app.use('/profile', profile);
app.use('/admin-ajax', ajax);
app.use('/logout', logout);
app.use('/administrator', administrator);



// catch 404 and forward to error handler
app.use(function(req, res, next) {
  var err = new Error('Not Found');
  err.status = 404;
  next(err);
});


// error handler
app.use(function(err, req, res, next) {
  // set locals, only providing error in development
  res.locals.message = err.message;
  res.locals.error = req.app.get('env') === 'development' ? err : {};

  // render the error page
  res.status(err.status || 500);
  res.render('error');
});


// var server = http.createServer(app)

// //reload(app);
// server.listen(app.get('port'), function () {
//  console.log('Web server listening on port ' + app.get('port'))
// });





module.exports = app;

中间件 - 检查用户是否已登录

middleware.isUserLoggedIn = function(){
    return function(req, res, next){
        if(!_.isEmpty(req.session) && !_.isEmpty(req.session.user)){
            return next();
        }        
        return res.send('Session Expired'); //only for testing purpose
        return res.redirect('/');//original code
    }
}

快递会应该存储记录的用户信息并提供每条路线的信息。

Answer 1

快速会话使用

MemoryStorage

故意不是为生产环境设计的。它会在大多数情况下泄漏内存，不会扩展到单个进程，而是用于调试和开发。

对于生产，您可以使用另一个存储，您可以找到大量可用的存储空间并与快速会话兼容。

以下链接包含兼容的会话商店

https://github.com/expressjs/session#compatible-session-stores

始终记住会话存储在服务器端。

Express-Session不会持续生产
