passport-accountkit
** NOTE This code is forked from passport-facebook an has only been altered in a few locations to support accountkit **
** Mostly broken **
Passport strategy for authenticating with Facebook's AccountKit using the OAuth 2.0 API.
This module lets you authenticate using AccountKit by Facebook in your Node.js applications. By plugging into Passport, Facebook authentication can be easily and unobtrusively integrated into any application or framework that supports Connect-style middleware, including Express.
Install
$ npm install passport-accountkit
Usage
Create an Application
Before using passport-accountkit
, you must register an application with
Facebook. If you have not already done so, a new application can be created at
Facebook Developers. Your application will
be issued an app ID and app 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 Facebook authentication strategy authenticates users using a Facebook
account and OAuth 2.0 tokens. The app 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
Facebook profile. The verify
callback must call cb
providing a user to
complete authentication.
passport.use(new AccountkitStrategy({
clientID: FACEBOOK_APP_ID,
appSecret: FACEBOOK_APP_SECRET,
callbackURL: "http://localhost:3000/auth/facebook/callback"
},
function(accessToken, refreshToken, profile, cb) {
User.findOrCreate({ facebookId: profile.id }, function (err, user) {
return cb(err, user);
});
}
));
Authenticate Requests
Use passport.authenticate()
, specifying the 'accountkit'
strategy, to
authenticate requests.
For example, as route middleware in an Express application:
app.get('/auth/facebook',
passport.authenticate('facebook'));
app.get('/auth/facebook/callback',
passport.authenticate('facebook', { failureRedirect: '/login' }),
function(req, res) {
// Successful authentication, redirect home.
res.redirect('/');
});
Examples
Developers using the popular Express web framework can refer to an example as a starting point for their own web applications.
FAQ
How do I ask a user for additional permissions?
If you need additional permissions from the user, the permissions can be
requested via the scope
option to passport.authenticate()
.
app.get('/auth/facebook',
passport.authenticate('facebook', { scope: ['user_friends', 'manage_pages'] }));
Refer to permissions with Facebook Login for further details.
How do I re-ask for for declined permissions?
Set the authType
option to rerequest
when authenticating.
app.get('/auth/facebook',
passport.authenticate('facebook', { authType: 'rerequest', scope: ['user_friends', 'manage_pages'] }));
Refer to re-asking for declined permissions for further details.
How do I obtain a user profile with specific fields?
The Facebook profile contains a lot of information about a user. By default,
not all the fields in a profile are returned. The fields need by an application
can be indicated by setting the profileFields
option.
new AccountkitStrategy({
clientID: FACEBOOK_APP_ID,
appSecret: FACEBOOK_APP_SECRET,
callbackURL: "http://localhost:3000/auth/facebook/callback",
profileFields: ['id', 'displayName', 'photos', 'email']
}), ...)
Refer to the User section of the Graph API Reference for the complete set of available fields.
How do I include app secret proof in API requests?
Set the enableProof
option when creating the strategy.
new FacebookStrategy({
clientID: FACEBOOK_APP_ID,
appSecret: FACEBOOK_APP_SECRET,
callbackURL: "http://localhost:3000/auth/facebook/callback",
enableProof: true
}, ...)
As detailed in securing graph API requests, requiring the app secret for server API requests helps prevent use of tokens stolen by malicous software or man in the middle attacks.
Why is #_=_ appended to the redirect URI?
This behavior is "by design" according to Facebook's response to a bug filed regarding this issue.
Fragment identifiers are not supplied in requests made to a server, and as such this strategy is not aware that this behavior is exhibited and is not affected by it. If desired, this fragment can be removed on the client side. Refer to this discussion on Stack Overflow for recommendations on how to accomplish such removal.
