passport token is not being authorized - node.js

Question

const JwtStrategy = require('passport-jwt').Strategy,
ExtractJwt = require('passport-jwt').ExtractJwt;
const User = require('../models/User');
const key = require('./keys').secret;
const mongoose = require('mongoose');
var opts = {}
opts.jwtFromRequest = ExtractJwt.fromAuthHeaderAsBearerToken();
opts.secretOrKey = key;
module.exports = (passport) => {
passport.use(new JwtStrategy(opts, function(jwt_payload, done) {
console.log(jwt_payload);
User.findById(jwt_payload.id, function(err, user) {
if (err) {
return done(err, false);
}
if (user) {
return done(null, user);
} else {
return done(null, false);
}
});
}))
}
I am using passport-jwt stratergy to validate with token but this is file is not running properly i even tried to console the payload here but this is not even logging it
passport.use(new JwtStrategy(opts, function(jwt_payload, done)
console.log(jwt_payload);
Token Stratergy
const payload = {
id: user.id,
username: user.username,
name: user.name
}
const token = jwt.sign(payload, config.secret, { expiresIn: 36000 });
return res.json({
success: true,
token: 'JWT ' + token,
user: {
id: user.id,
name: user.name,
username: user.username
}
})
And when i am using this on the protected routes it is not authorizing the protected routes
Result = Unauthorized
router.get('/profile', passport.authenticate('jwt', { session: false }), (req, res) => {
res.send("Profile");
});

Answer 1

The reason your authentication is not working is that you've used the legacy token prefix "JWT" and a modern JWT (fromAuthHeaderAsBearerToken) extractor as an option to your strategy.
You can do one of the steps to fix the problem:
change the token prefix to 'Bearer ' + token
change the token extractor:
opts.jwtFromRequest = ExtractJwt.fromAuthHeaderWithScheme("JWT");
