This is my passport.js
var FacebookStrategy = require('passport-facebook').Strategy;
var User = require('./app/models/users');
var config = require('./config');
module.exports = function (passport) {
passport.serializeUser(function (user, done) {
done(null, user.id);
});
passport.deserializeUser(function (id, done) {
User.findById(id, function (err, user) {
done(err, user);
});
});
passport.use(new FacebookStrategy({
clientID: config.facebook.appId,
clientSecret: config.facebook.appSecret,
callbackURL: config.facebook.redirectUrl,
profileFields: ['id', 'name', 'displayName', 'emails', 'photos']
},
function (accessToken, refreshToken, profile, done) {
process.nextTick(function () {
User.findOne({'facebook.id': profile.id}, function (err, user) {
console.log(profile);
if (err) {
// console.log("tick errr");
return done(err)
}
;
if (user)
return done(null, user);
else {
var newUser = new User();
newUser.facebook.id = profile.id;
newUser.facebook.token = accessToken;
newUser.facebook.name = profile.displayName;
newUser.facebook.email = profile.emails[0].value;
newUser.facebook.picurl = profile.photos[0].value;
// console.log("access to ken is "+accessToken);
//console.log(newUser.facebook.id);
newUser.save(function (err) {
if (err)
console.log(err);
return done(null, newUser);
})
}
});
});
// done(null, profile);
}
));
api.js
api.get('/auth/facebook', function (req, res, next) {
passport.authenticate('facebook', {scope: ['email']})(req, res, next);
});
api.get('/auth/facebook/callback',
passport.authenticate('facebook', {
successRedirect: '#/home',
failureRedirect: '#/login'
})
);
};
I am having trouble using facebook login. I am getting following error:
FacebookTokenError: This authorization code has been used.

I am able to login on facebook page and then after that this error shows up. The details which i am fetching from facebook are still successfully stored in my database; I think it has something to do with the auth/facebook/callback
users.js file :
var UserSchema = mongoose.Schema({
local: {
name: String,
username: {type: String, index: {unique: true}},
password: {type: String, select: false}
},
facebook: {
id: String,
token: String,
email: String,
name: String,
picurl: String,
},
favouriteid: [{eventid: String}]
});
UserSchema.pre('save', function(next) {
var user = this;
if (!user.isModified('local.password')) return next();
bcrypt.hash(user.local.password, null, null, function (err, hash) {
if(err) return next(err);
user.local.password = hash;
next();
});
});
UserSchema.methods.comparePassword = function(password) {
var user = this;
var a = bcrypt.compareSync(password, user.local.password);
if (a == true)
return true;
else {
console.log('error in compare password');
return false;
}
}
