Build Status Coverage Status Dependency Status Code Climate Online docs Gem Version

The source code is available on GitHub and the documentation on RubyDoc.

Installing and Configuring Fb::Auth

First, add fb-auth to your Gemfile:

gem 'fb-auth'

Then run bundle install.

Fb::Auth will require an Client ID and an Client Secret which you can obtain after registering as a developer on Facebook for developers.

By default, Fb::Auth will look for the environment variables called FB_CLIENT_ID and FB_CLIENT_SECRET. You can put those keys in your .bash_profile and Fb::Auth will work.

export FB_CLIENT_ID="YourAppID"
export FB_CLIENT_SECRET="YourAppSecret"

Usage

Fb::Auth#url

The url method helps you obtain a URL where to redirect users who need to authenticate with their Facebook account in order to use your application:

redirect_uri = 'https://example.com/auth' # REPLACE WITH REAL ONE
Fb::Auth.new(redirect_uri: redirect_uri, scope: ["manage_pages"]).url
 # => https://www.facebook.com/dialog/oauth?client_id=...&scope=manage_pages&redirect_uri=https%3A%2F%2Fexample.com%2Fauth

Note that access is requested with permission to access email, manage pages, read insights, et cetera. See https://developers.facebook.com/docs/facebook-login/permissions

Fb::Auth#access_token

After users have authenticated with their Facebook account, they will be redirected to the redirect_uri you indicated, with an extra code query parameter, e.g. https://example.com/auth?code=1234#_=_

The access_token method allows you to get a non-expiring access token of the user:

redirect_uri = 'https://example.com/auth' # REPLACE WITH REAL ONE
code = '1234#_=_' # REPLACE WITH REAL ONE
Fb::Auth.new(redirect_uri: redirect_uri, code: code).access_token
 # => "kefjej49s82hFS@2333233222FDh66"
