Node.js
Paspoort integratie

Opmerkingen

Ermee beginnen

Paspoort moet worden geïnitialiseerd met middleware passport.initialize() . Om inlogsessies te gebruiken, is middleware passport.session() vereist.

Merk op dat de methoden passport.serialize() en passport.deserializeUser() moeten worden gedefinieerd. Paspoort zal gebruikersinstanties serialiseren en deserialiseren van en naar de sessie

const express = require('express');
const session = require('express-session');
const passport = require('passport');
const cookieParser = require('cookie-parser');
const app = express();

// Required to read cookies
app.use(cookieParser());

passport.serializeUser(function(user, next) {
    // Serialize the user in the session
    next(null, user);
});

passport.deserializeUser(function(user, next) {
    // Use the previously serialized user
        next(null, user);
});

// Configuring express-session middleware
app.use(session({
    secret: 'The cake is a lie',
    resave: true,
    saveUninitialized: true
}));

// Initializing passport
app.use(passport.initialize());
app.use(passport.session());

// Starting express server on port 3000
app.listen(3000);

Lokale authenticatie

De paspoort-lokale module wordt gebruikt om een lokale authenticatie te implementeren.

Met deze module kunt u authenticeren met een gebruikersnaam en wachtwoord in uw Node.js-applicaties.

Gebruiker registreren:

const passport = require('passport');
const LocalStrategy = require('passport-local').Strategy;

// A named strategy is used since two local strategy are used :
// one for the registration and the other to sign-in
passport.use('localSignup', new LocalStrategy({
    // Overriding defaults expected parameters,
    // which are 'username' and 'password'
    usernameField: 'email',
    passwordField: 'password',
    passReqToCallback: true // allows us to pass back the entire request to the callback    .
},
function(req, email, password, next) {
    // Check in database if user is already registered
    findUserByEmail(email, function(user) {
        // If email already exists, abort registration process and
        // pass 'false' to the callback
        if (user) return next(null, false);
        // Else, we create the user
        else {
            // Password must be hashed !
            let newUser = createUser(email, password);

            newUser.save(function() {
                // Pass the user to the callback
                return next(null, newUser);
            });
        }
    });
});

Inloggen van de gebruiker:

const passport = require('passport');
const LocalStrategy = require('passport-local').Strategy;

passport.use('localSignin', new LocalStrategy({
    usernameField : 'email',
    passwordField : 'password',
},
function(email, password, next) {
    // Find the user
    findUserByEmail(email, function(user) {
        // If user is not found, abort signing in process
        // Custom messages can be provided in the verify callback
        // to give the user more details concerning the failed authentication
        if (!user) 
            return next(null, false, {message: 'This e-mail address is not associated with any account.'});
        // Else, we check if password is valid
        else {
            // If password is not correct, abort signing in process
            if (!isPasswordValid(password)) return next(null, false);
            // Else, pass the user to callback
            else return next(null, user);
        }
    });
});

Routes maken:

// ...
app.use(passport.initialize());
app.use(passport.session());

// Sign-in route
// Passport strategies are middlewares
app.post('/login', passport.authenticate('localSignin', {
    successRedirect: '/me',
    failureRedirect: '/login'
});

// Sign-up route
app.post('/register', passport.authenticate('localSignup', {
    successRedirect: '/',
    failureRedirect: '/signup'
});

// Call req.logout() to log out
app.get('/logout', function(req, res) {
    req.logout();
    res.redirect('/');
});

app.listen(3000);

Facebook authenticatie

De paspoort-facebook- module wordt gebruikt om een Facebook- authenticatie te implementeren. In dit voorbeeld wordt de gebruiker gemaakt als de gebruiker niet bestaat bij het aanmelden.

Implementatie strategie:

const passport = require('passport');
const FacebookStrategy = require('passport-facebook').Strategy;

// Strategy is named 'facebook' by default
passport.use({
    clientID: 'yourclientid',
    clientSecret: 'yourclientsecret',
    callbackURL: '/auth/facebook/callback'
},
// Facebook will send a token and user's profile
function(token, refreshToken, profile, next) {
    // Check in database if user is already registered
    findUserByFacebookId(profile.id, function(user) {
        // If user exists, returns his data to callback
        if (user) return next(null, user);
        // Else, we create the user
        else {
            let newUser = createUserFromFacebook(profile, token);

            newUser.save(function() {
                // Pass the user to the callback
                return next(null, newUser);
            });
        }
    });
});

Routes maken:

// ...
app.use(passport.initialize());
app.use(passport.session());

// Authentication route
app.get('/auth/facebook', passport.authenticate('facebook', {
    // Ask Facebook for more permissions
    scope : 'email'
}));

// Called after Facebook has authenticated the user
app.get('/auth/facebook/callback',
    passport.authenticate('facebook', {
        successRedirect : '/me',
        failureRedirect : '/'
}));


//...

app.listen(3000);

Eenvoudige gebruikersnaam-wachtwoordauthenticatie

In uw routes / index.js

Hier is de user het model voor de userSchema

router.post('/login', function(req, res, next) {
    if (!req.body.username || !req.body.password) {
        return res.status(400).json({
            message: 'Please fill out all fields'
        });
    }
    
    passport.authenticate('local', function(err, user, info) {
        if (err) {
            console.log("ERROR : " + err);
            return next(err);
        }

        if(user) (
            console.log("User Exists!")
            //All the data of the user can be accessed by user.x
            res.json({"success" : true});
            return;
        } else {
            res.json({"success" : false});
            console.log("Error" + errorResponse());
            return;
        }
    })(req, res, next);
});

Google Passport-authenticatie

We hebben een eenvoudige module beschikbaar in npm voor de naam van de brilauthenticatie paspoort-google-oauth20

Beschouw het volgende voorbeeld In dit voorbeeld hebt u een map gemaakt, namelijk config met het bestand passport.js en google.js in de hoofdmap. Neem in uw app.js het volgende op

var express = require('express');
var session = require('express-session');
var passport = require('./config/passport'); // path where the passport file placed  
var app = express();
passport(app);

// andere code om de server te initialiseren, foutafhandeling

Neem in het bestand passport.js in de map config de volgende code op

var passport = require  ('passport'),
google = require('./google'),
User = require('./../model/user'); // User is the  mongoose model

module.exports = function(app){
  app.use(passport.initialize());
  app.use(passport.session());
  passport.serializeUser(function(user, done){
      done(null, user);
  });
  passport.deserializeUser(function (user, done) {
     done(null, user);
  });
  google();
};

In het google.js-bestand in dezelfde configuratie map zijn onder meer het volgende

var passport = require('passport'),
GoogleStrategy = require('passport-google-oauth20').Strategy,
User = require('./../model/user');
module.exports = function () {
passport.use(new GoogleStrategy({
        clientID: 'CLIENT ID',
        clientSecret: 'CLIENT SECRET',
        callbackURL: "http://localhost:3000/auth/google/callback"
    },
    function(accessToken, refreshToken, profile, cb) {
        User.findOne({ googleId : profile.id }, function (err, user) {
            if(err){
                return cb(err, false, {message : err});
            }else {
                if (user != '' && user != null) {
                    return cb(null, user, {message : "User "});
                } else {
                    var username  = profile.displayName.split(' ');
                    var userData = new User({
                        name : profile.displayName,
                        username : username[0],
                        password : username[0],
                        facebookId : '',
                        googleId : profile.id,
                    });
                    // send email to user just in case required to send the newly created
                    // credentails to user for future login without using google login
                    userData.save(function (err, newuser) {
                        if (err) {
                            return cb(null, false, {message : err + " !!! Please try again"});
                        }else{
                            return cb(null, newuser);
                        }
                    });
                }
            }
        });
      }
  ));
};

In dit voorbeeld, als de gebruiker niet in DB is, maakt u een nieuwe gebruiker in DB voor lokale referentie met behulp van de veldnaam googleId in gebruikersmodel.
