passport-geoaxis-oauth20
Passport strategy for authenticating with GEOAxIS using the OAuth 2.0 API.
This module lets you authenticate using GEOAxIS in your Node.js applications. By plugging into Passport, GEOAxIS authentication can be easily and unobtrusively integrated into any application or framework that supports Connect-style middleware, including Express.
Install
$ npm install passport-geoaxis-oauth20
Usage
Create an Application
Before using passport-geoaxis-oauth20, you must register an application with
GEOAxIS. Your application will be issued a client ID and client secret, which need to be
provided to the strategy. You will also need to configure a redirect URI which
matches the route in your application.
Configure Strategy
The GEOAxIS authentication strategy authenticates users using a GEOAxIS account
and OAuth 2.0 tokens. The client ID and secret obtained when creating an
application are supplied as options when creating the strategy. The strategy
also requires a verify callback, which receives the access token and optional
refresh token, as well as profile which contains the authenticated user's
GEOAxIS profile. The verify callback must call cb providing a user to
complete authentication.
var GeoaxisStrategy = require('passport-geoaxis-oauth20').Strategy;
passport.use(new GeoaxisStrategy({
clientID: GEOAXIS_CLIENT_ID,
clientSecret: GEOAXIS_CLIENT_SECRET,
callbackURL: "http://www.example.com/auth/geoaxis/callback"
},
function(accessToken, refreshToken, profile, cb) {
User.findOrCreate({ geoaxisId: profile._json.uid }, function (err, user) {
return cb(err, user);
});
}
));
Authenticate Requests
Use passport.authenticate(), specifying the 'geoaxis' strategy, to
authenticate requests.
For example, as route middleware in an Express application:
app.get('/auth/geoaxis',
passport.authenticate('geoaxis', { scope: ['profile'] }));
app.get('/auth/geoaxis/callback',
passport.authenticate('geoaxis', { failureRedirect: '/login' }),
function(req, res) {
// Successful authentication, redirect home.
res.redirect('/');
});
