Passport strategies for authenticating with Google using OAuth 1.0a and OAuth 2.0.
This module lets you authenticate using Google in your Node.js applications. By plugging into Passport, Google authentication can be easily and unobtrusively integrated into any application or framework that supports Connect-style middleware, including Express.
$ npm install passport-google-oauth
The Google OAuth 1.0 authentication strategy authenticates users using a Google
account and OAuth tokens. The strategy requires a verify callback, which
accepts these credentials and calls done providing a user, as well as options
specifying a consumer key, consumer secret, and callback URL.
var GoogleStrategy = require('passport-google-oauth').OAuthStrategy;
passport.use(new GoogleStrategy({
consumerKey: GOOGLE_CONSUMER_KEY,
consumerSecret: GOOGLE_CONSUMER_SECRET,
callbackURL: "http://127.0.0.1:3000/auth/google/callback"
},
function(token, tokenSecret, profile, done) {
User.findOrCreate({ googleId: profile.id }, function (err, user) {
return done(err, user);
});
}
));Use passport.authenticate(), specifying the 'google' strategy, to
authenticate requests.
For example, as route middleware in an Express application:
app.get('/auth/google',
passport.authenticate('google', { scope: 'https://www.google.com/m8/feeds' }));
app.get('/auth/google/callback',
passport.authenticate('google', { failureRedirect: '/login' }),
function(req, res) {
// Successful authentication, redirect home.
res.redirect('/');
});The Google OAuth 2.0 authentication strategy authenticates users using a Google
account and OAuth 2.0 tokens. The strategy requires a verify callback, which
accepts these credentials and calls done providing a user, as well as
options specifying a client ID, client secret, and callback URL.
var GoogleStrategy = require('passport-google-oauth').OAuth2Strategy;
passport.use(new GoogleStrategy({
clientID: GOOGLE_CLIENT_ID,
clientSecret: GOOGLE_CLIENT_SECRET,
callbackURL: "http://127.0.0.1:3000/auth/google/callback"
},
function(accessToken, refreshToken, profile, done) {
User.findOrCreate({ googleId: profile.id }, function (err, user) {
return done(err, user);
});
}
));Use passport.authenticate(), specifying the 'google' strategy, to
authenticate requests.
For example, as route middleware in an Express application:
app.get('/auth/google',
passport.authenticate('google'));
app.get('/auth/google/callback',
passport.authenticate('google', { failureRedirect: '/login' }),
function(req, res) {
// Successful authentication, redirect home.
res.redirect('/');
});For a complete, working example, refer to the OAuth 1.0 example and the OAuth 2.0 example.
