my $fb = Net::Facebook::Oauth2->new( application_id => 'your_application_id', application_secret => 'your_application_secret', callback => 'http://yourdomain.com/facebook/callback' ); # get the authorization URL for your application my $url = $fb->get_authorization_url( scope => [ 'public_profile', 'email', 'user_posts', 'manage_pages' ], display => 'page' ); Now redirect the user to this C<$url>. Once the user authorizes your application, Facebook will send him/her back to your application, on the C link provided above. Inside that callback route, use the verifier code parameter that Facebook sends to get the access token: # param() below is a bogus function. Use whatever your web framework # provides (e.g. $c->req->param('code'), $cgi->param('code'), etc) my $code = param('code'); my $access_token = $fb->get_access_token(code => $code); If you got so far, your user is logged! Save this access token in your database or session. Later on you can use it to communicate with Facebook on behalf of this user: my $fb = Net::Facebook::Oauth2->new( access_token => $access_token ); my $info = $fb->get( 'https://graph.facebook.com/v2.8/me' # Facebook API URL ); print $info->as_json; =head1 DESCRIPTION Net::Facebook::Oauth2 gives you a way to simply access FaceBook Oauth 2.0 protocol For more information please see example folder shipped with this Module, or refer to the L. =head1 INSTALLATION cpanm Net::Facebook::Oauth2 Or the old-fashioned manual way: perl Makefile.PL make make test make install =head1 AUTHOR Mahmoud A.

One month prior to that, using this version of Net::Facebook::Oauth2 will trigger a warning message. =head1 SYNOPSIS Somewhere in your application's login process: use Net::Facebook::Oauth2; my $fb = Net::Facebook::Oauth2->new( application_id => 'your_application_id', application_secret => 'your_application_secret', callback => 'http://yourdomain.com/facebook/callback' ); # get the authorization URL for your application my $url = $fb->get_authorization_url( scope => [ 'public_profile', 'email', 'user_about_me', 'manage_pages' ], display => 'page' ); Now redirect the user to this C<$url>. Once the user authorizes your application, Facebook will send him/her back to your application, on the C link provided above. PLEASE NOTE THAT YOU MUST PRE-AUTHORIZE YOUR CALLBACK URI ON FACEBOOK'S APP DASHBOARD. Inside that callback route, use the verifier code parameter that Facebook sends to get the access token: # param() below is a bogus function. Use whatever your web framework # provides (e.g. $c->req->param('code'), $cgi->param('code'), etc) my $code = param('code'); my $access_token = $fb->get_access_token(code => $code); If you got so far, your user is logged! Save this access token in your database or session. Later on you can use that access token to communicate with Facebook on behalf of this user: my $fb = Net::Facebook::Oauth2->new( access_token => $access_token ); my $info = $fb->get( 'https://graph.facebook.com/v2.8/me' # Facebook API URL ); print $info->as_json; =head1 DESCRIPTION Net::Facebook::Oauth2 gives you a way to simply access FaceBook Oauth 2.0 protocol For more information please see example folder shipped with this Module =head1 SEE ALSO For more information about Facebook Oauth 2.0 API Please Check L get/post Facebook Graph API L =head1 USAGE =head2 Cnew( %args )> Returns a new object to handle user authentication. Pass arguments as a hash. The following arguments are I unless you're passing an access_token (see optional arguments below): =over 4 =item * C Your application id as you get from facebook developers platform when you register your application =item * C Your application secret id as you get from facebook developers platform when you register your application =back The following arguments are I: =over 4 =item * C If you want to instantiate an object to an existing access token, you may do so by passing it to this argument. =item * C The user agent that will handle requests to Facebook's API. Defaults to LWP::UserAgent, but can be any method that implements the methods C, C and C and whose response to such methods implements C and C. =item * C See C under the C method below. =item * C Overrides the default (2.8) API endpoint for Facebook's oauth. Used mostly for testing new versions. =item * C Overrides the default (2.8) API endpoint for Facebook's access token. Used mostly for testing new versions. =item * C When a user declines a given permission, you must reauthorize them. But when you do so, any previously declined permissions will not be asked again by Facebook. Set this argument to C<'rerequest'> to explicitly tell the dialog you're re-asking for a declined permission. =back =head2 C<$fb-Eget_authorization_url( %args )> Returns an authorization URL for your application. Once you receive this URL, redirect your user there in order to authorize your application. The following argument is I: =over 4 =item * C callback => 'http://example.com/login/facebook/success' The callback URL, where Facebook will send users after they authorize your application. YOU MUST CONFIRM THIS URL ON FACEBOOK'S APP DASHBOARD. To do that, go to the App Dashboard, click Facebook Login in the right-hand menu, and check the B in the Client OAuth Settings section. =back This method also accepts the following I arguments: =over 4 =item * C scope => ['user_events','manage_pages', ...] Array of Extended permissions as described by facebook Oauth API. You can get more information about scope/Extended Permission from L Please note that requesting information other than C, C and C B =item * C state => '123456abcde' An arbitrary unique string provided by you to guard against Cross-site Request Forgery. =item * C display => 'page' How to display Facebook Authorization page. Defaults to C. Can be any of the following: =over 4 =item * C This will display facebook authorization page as full page =item * C This option is useful if you want to popup authorization page as this option tell facebook to reduce the size of the authorization page =item * C From the name, for wab and mobile applications this option is the best facebook authorization page will fit there :) =back =item * C response_type => 'code' When the redirect back to the app occurs, determines whether the response data is in URL parameters or fragments. Defaults to C, which is Facebook's default and useful for cases where the server handles the token (which is most likely why you are using this module), but can be also be C, C, or C. Please see L<< Facebook's login documentation|https://developers.facebook.com/docs/facebook-login/manually-build-a-login-flow >> for more information. =back =head2 C<$fb-Eget_access_token( %args )> This method issues a GET request to Facebook's API to retrieve the access token string for the specified code (passed as an argument). Returns the access token string or raises an exception in case of errors. You should call this method inside the route for the callback URI defined in the C method. It receives the following arguments: =over 4 =item * C This is the verifier code that Facebook sends back to your callback URL once user authorize your app, you need to capture this code and pass to this method in order to get the access token. Verifier code will be presented with your callback URL as code parameter as the following: http://your-call-back-url.com?code=234er7y6fdgjdssgfsd... Note that if you have fiddled with the C argument, you might not get this parameter properly. =back When the access token is returned you need to save it in a secure place in order to use it later in your application. The token indicates that a user has authorized your site/app, meaning you can associate that token to that user and issue API requests to Facebook on their behalf. To know I user has granted you the authorization (e.g. when building a login system to associate that token with a unique user on your database), you must make a request to fetch Facebook's own unique identifier for that user, and then associate your own user's unique id to Facebook's. This is usually done by making a GET request to the C API endpoint, as shown in the SYNOPSIS. B Expect that the length of all access token types will change over time as Facebook makes changes to what is stored in them and how they are encoded. You can expect that they will grow and shrink over time. Please use a variable length data type without a specific maximum size to store access tokens. =head2 C<$fb-Eget( $url, $args )> Sends a GET request to Facebook and stores the response in the given object. =over 4 =item * C Facebook Graph API URL as string. You must provide the full URL. =item * C<$args> hashref of parameters to be sent with graph API URL if required. =back You can access the response using the following methods: =over 4 =item * C<$responseEas_json> Returns response as json object =item * C<$responseEas_hash> Returns response as perl hashref =back For more information about facebook graph API, please check http://developers.facebook.com/docs/api =head2 C<$fb-Epost( $url, $args )> Send a POST request to Facebook and stores the response in the given object. See the C and C methods above for how to retrieve the response. =over 4 =item * C Facebook Graph API URL as string =item * C<$args> hashref of parameters to be sent with graph API URL =back For more information about facebook graph API, please check L =head2 C<$fb-Edelete( $url, $args )> Send a DELETE request to Facebook and stores the response in the given object.
