nodejs express session is undefined

Question

Myapp.js脚本

var express_session = require('express-session');
var session = express_session({
secret: 'secretkey',
resave: true,
saveUninitialized: true,
cookie: { maxAge: 60 * 60 * 1000 },
});
var indexRouter = require('./routes/index');
var usersRouter = require('./routes/users');
var app = express();
// view engine setup
app.set('views', path.join(__dirname, 'views'));
app.set('view engine', 'pug');
app.use(cookieParser('secretkey'));
app.use(session);
app.use(logger('dev'));
app.use(fileUpload());
app.use(express.json());
app.use(express.urlencoded({ extended: false }));
app.use(express.static(path.join(__dirname, 'public')));
app.use('/', indexRouter);
app.use('/users', session, usersRouter);
// catch 404 and forward to error handler
app.use(function(req, res, next) {
next(createError(404));
});
// 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');
});
module.exports = app;

我的<<p> strong> users.js 脚本

var express = require('express');
var router = express.Router();
router.get('/enter', function(req, res, next) {
req.session.user = req.query.username;
res.redirect('/users/login');
});
module.exports = router;

,req.session是定义TypeError:无法设置未定义的属性(设置"user")我在路由之前放置了app.use(session)，但仍然不起作用。尝试在app.use('/'， session, indexRouter)中添加会话-不工作。

///更新我改变了我的indexRouter，现在它的作品!!!!:

var express = require('express');
var router = express.Router();
var express_session = require('express-session');
var session = express_session({
secret: 'secret',
resave: true,
saveUninitialized: true,
cookie: { maxAge: 24 * 60 * 60 * 1000 },
});
router.use(session);
router.get('/', function(req, res, next) {
if(req.session && req.session.user){
res.render('index', { title: 'Adviser', user: req.session.user });
} else {
res.redirect('/users/login');
}
});
module.exports = router;
