设置为req并在另一条路线中访问

Question

My user have to login before he can access any route, but why in the second route res.username is undefined?

router.post('/login', passport.authenticate('local'), function(req, res) {
    res.username = req.user.name;
    res.json({result:1,username:req.user.name}); //work
});

router.post('/some_other_route', function(req, res, next) {
    console.log(res.username) // undefined
})

I'm using express-session middleware with passport.

If you use express-session correctly, you should use req.session.username = req.user.name; .

Here is the link: https://github.com/expressjs/session

req.session

To store or access session data, simply use the request property req.session, which is (generally) serialized as JSON by the store, so nested objects are typically fine. For example below is a user-specific view counter:

// Use the session middleware
app.use(session({ secret: 'keyboard cat', cookie: { maxAge: 60000 }}))

// Access the session as req.session
app.get('/', function(req, res, next) {
  var sess = req.session
  if (sess.views) {
    sess.views++
    res.setHeader('Content-Type', 'text/html')
    res.write('<p>views: ' + sess.views + '</p>')
    res.write('<p>expires in: ' + (sess.cookie.maxAge / 1000) + 's</p>')
    res.end()
  } else {
    sess.views = 1
    res.end('welcome to the session demo. refresh!')
  }
})
