会话在node.js和express.js中的某些页面上变为空

Question

I am using express in node.js and trying to set the session variable here is my code:-

var express = require('express');
app.use(express.session({ secret: 'mysecret', cookie: { maxAge: 999999999, path: '/' } })); // session secret

Here m setting session:-

 app.get('/login', function (req, res) {
   req.session.Name="Hello";
 }

its working fine and return value for these routes:-

app.get('/users',function (req, res) {
    console.log(req.session.Name);
    res.render('home.ejs');
});
app.get('/userList',function (req, res) {
    console.log(req.session.Name);
    res.render('home.ejs');
});

But not working in this route and always return undefined or null:-

 app.get('/user/:id', function (req, res) {
    console.log(req.session.Name);
    res.render('home.ejs');
});

what I am doing wrong? Please help me to solve this issue. Thanks

May be you use an outdated version of packages. Same code is work with package express-session. ( https://github.com/expressjs/session ). Example code is below:

    var express = require('express');
    var session = require('express-session');
    var app = express();
    app.use(session({
        secret: 'mysecret',
        cookie: {
            maxAge: 999999999,
            path: '/'
        }
    })); // session secret
    app.get('/login', function(req, res) {
        req.session.Name = "Hello";
        res.send('Hello World');
    });
    app.get('/users', function(req, res) {
        console.log(req.session.Name);
        res.send('Hello World');
    });
    app.get('/userList', function(req, res) {
        console.log(req.session.Name);
        res.send('Hello World');
    });
    app.get('/user/:id', function(req, res) {
        console.log(req.session.Name);
        res.send('Hello World');
    });
    app.listen(8080);
