Passport-jwt issue : JWT token is working with postman but not working with UI api call - jwt

Question

I have integrated passport-jwt for authentication purpose. It's working like charm but whenever Frontend guy use it from frontend angular 2 its giving Unauthorised 401 . I've tried alot but not getting any clue, it must be a silly mistake though.
my passport strategy file is as
let JwtStrategy = require('passport-jwt').Strategy,
ExtractJwt = require('passport-jwt').ExtractJwt;
//let fromHeader = require('passport-jwt').fromHeader
// load up the user model
const User = require('../components/user/model');
const database = require('./database'); // get db config file
const config = require('./config'); // get db config file
module.exports = function(passport) {
//var passportStrategy = function(passport){
let opts = {};
opts.jwtFromRequest = ExtractJwt.fromAuthHeader();
//opts.jwtFromRequest = ExtractJwt.fromAuthHeaderWithScheme("JWT");
console.log("opts.jwtFromRequest==",opts.jwtFromRequest);
opts.secretOrKey = config.secret;//config.secret;
passport.use(new JwtStrategy(opts, function(jwt_payload, done) {
//console.log("opt==",JSON.stringify(opt));
//console.log("jwt_payload===",jwt_payload);
User.findOne({_id: jwt_payload._doc._id}, function(err, user) {
if (err) {
return done(err, false);
}
if (user) {
done(null, user);
} else {
done(null, false);
}
});
}));
};
my route is as
app.get("/api/user/getAll",
passport.authenticate('jwt',{session:false}),
userController.fetchUsers
);
And frontend header append is as follows :
logoutUser(token) {
//const userData = JSON.stringify(userInfo);
var headers = new Headers();
headers.append('Content-Type', 'application/json');
headers.append('Authorization', token); //e.g.token = JWT dasddddasdsda
//headers.append('Authentication', token);
console.log(headers)
return this.http.post('http://localhost:9000/api/user/logout', { headers: headers })
.map((response: Response) =〉 {
return response.json()
})
.catch(this.errorHandler);
}
It would really great if anyone can assist me further to identify the mistake.

Answer 1

Second argument for the post method is payload.
so this code below
this.http.post('http://localhost:9000/api/user/logout', { headers: headers })
has to be
this.http.post('http://localhost:9000/api/user/logout', {}, { headers: headers })
