Fb::Auth can authenticate a Facebook user and return an access token with permission to manage pages of that user.
Installing and Configuring Fb::Auth
First, add fb-auth to your Gemfile:
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_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"
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 ::.(redirect_uri: redirect_uri, scope: ["manage_pages"]). # => 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
After users have authenticated with their Facebook account, they will be
redirected to the
redirect_uri you indicated, with an extra
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 ::.(redirect_uri: redirect_uri, code: code). # => "kefjej49s82hFS@2333233222FDh66"
