5 years ago Did you compare your files to Brad's repo. I would also look at the Issues page and comments. Many people have had the same error and posted replies have helped them. There were changes from the original creation of the Video. The Repo merged some changes before. I would simply check and compare files and read the issues pages. You might find your answer.

Here is my code for users.js const router = express.Router(); const passport = require('passport'); const jwt = require('jsonwebtoken'); const config = require('../config/database'); const User = require('../models/user');
// Register router.post('/register', (req, res, next) => { let newUser = new User ({ name: req.body.name, email: req.body.email, username: req.body.username, password: req.body.password });
User.addUser(newUser, (err, user) => { if(err) { res.json({success: false, msg: 'Failed to register user'}); } else { res.json({success: true, msg: 'User registered'}); } }); });
//authenticate router.post('/authenticate', (req, res, next) => { const username = req.body.username; const password = req.body.password;
User.getUserByUsername(username, (err, user) => { if (err) throw err; if (!user) { return res.json({ success: false, msg: 'user not found' }); } User.comparePassword(password, user.password, (err, isMatch) => { console.log('test'); if (err) throw err; if (isMatch) { const token = jwt.sign({data: user}, config.secret, { expiresIn: 604800 }); res.json({ succes: true, token: 'JWT ' + token, user: { id: user._id, name: user.name, username: user.username, email: user.email } }) } else { return res.json({ succes: false, msg: 'wrong password' }); } })
}) })
// Profile router.get('/profile', passport.authenticate('jwt', {session:false}), (req, res, next) => { res.json({user: req.user}); });
module.exports = router;
Here is my passport.js: const JwtStrategy = require('passport-jwt').Strategy; const ExtractJwt = require('passport-jwt').ExtractJwt; const User = require('../models/user'); const config = require('../config/database');
module.exports = function(passport){ let opts = {}; opts.jwtFromRequest = ExtractJwt.fromAuthHeaderAsBearerToken(); opts.secretOrKey = config.secret; passport.use(new JwtStrategy(opts, (jwt_payload, done) => { User.getUserById(jwt_payload.data._id, (err, user) => { if(err){ return done(err, false); }
if(user){
return done(null, user);
} else {
return done(null, false);

});})); }
Any ideas?
