Node.js - Express.js JWT always returns an invalid token error in browser response

Question

I'm using node.js and express.js with the express-jwt module, and I have set up a simple HTTP server to test everything: This is the node code involved: ``` app.set('port', process.env.PORT || 3000); app.use(express.methodOverride()); app.use(allow_cross_domain); app.use('/api', expressJwt({secret: '09qrjjwef923jnrge$5ndjwk'})); app.use(express.json()); app.use(express.urlencoded()); app.use('/', express.static(__dirname + '/')); app.use(function(err, req, res, next){ if (err.constructor.name === 'UnauthorizedError') { res.send(401, 'Unauthorized'); } }); app.get('login',function(req,res){ //... jwt.sign(results.username+results.email, secret, { expiresInMinutes: 9000000000*9393939393393939393939 }); }); app.post('api/profile',function(req,res){ console.log(req.user); // this return undefined in console res.send(req.user); // response is pending and dunno why it returns error in browser console }); ``` So once I open the `/login` URL I get logged in and I send the session token to `ap…

```
var expressJwt = require('express-jwt');
var jwt = require('jsonwebtoken');

var SECRET = 'shhhhhhared-secret';

app.use('/api', expressJwt({secret: SECRET}));

app.post('/authenticate', function (req, res) {
  //TODO validate req.body.username and req.body.password
  //if is invalid, return 401
  if (!(req.body.username === 'john.doe' && req.body.password === 'foobar')) {
    res.send(401, 'Wrong user or password');
    return;
  }

var profile = {
    first_name: 'John',
    last_name: 'Doe',
    email: 'john@doe.com',
    id: 123
  };

// We are sending the profile inside the token
  var token = jwt.sign(profile, SECRET, { expiresIn: 18000 }); // 60*5 minutes

res.json({ token: token });
});

app.get('/api/protected', 
  function(req, res) {  
    res.json(req.user);
  });
```
