Passport-Google-AuthCode

Passport strategy for authenticating with Google one time authorization code using the OAuth 2.0 API.

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.

Installation

$ npm install passport-google-authcode

Usage

Require Strategy

Require the passport-google-authcode Strategy along with passport

var passport = require('passport');
var GoogleAuthCodeStrategy = require('passport-google-authcode').Strategy;

Configure Strategy

The Google 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 app ID and app secret.

passport.use(new GoogleAuthCodeStrategy({
    clientID: GOOGLE_CLIENT_ID,
    clientSecret: GOOGLE_CLIENT_SECRET
  },
  function(accessToken, refreshToken, profile, done) {
    User.findOrCreate({ googleId: profile.id }, function (err, user) {
      return done(err, user);
    });
  }
));

Authenticate Requests

Use passport.authenticate(), specifying the 'google-authcode' strategy, to authenticate requests.

app.post('/auth/google/authcode',
  passport.authenticate('google-authcode'),
  function (req, res) {
    // do something with req.user
    res.send(req.user? 200 : 401);
  }
);

The post request to this route should include a JSON object with the key code set to the one time authorization code you receive from google.
