WWW::Facebook::API::Auth - Facebook Authentication

    use WWW::Facebook::API;

Methods for accessing auth with WWW::Facebook::API

Returns the WWW::Facebook::API base object.
Constructor.
auth.createToken of the Facebook API. Will always return the token string, regardles of the "parse" setting in WWW::Facebook::API: 

    $token = $client->auth->create_token;
auth.getSession of the Facebook API. If you have the desktop attribute set to true and $token isn't passed in, the return value from "$client->auth->create_token" will be used. If the desktop attribute is set to false the $token must be the auth_token returned from Facebook to your web app for that user: 

    if ( $q->param('auth_token')  ) {
        $client->auth->get_session( $q->param('auth_token') );
    }

"get_session" automatically sets "session_uid", "session_key", and "session_expires" for $client. It returns nothing.

Only for desktop apps. It first calls "create_token" to get a valid token. It then opens the user's default browser and have them sign in to the Facebook application. If "browser" is passed in, the module will use that string as the command to execute, e.g.: 

    system qq($browser_cmd "$login_url");

After the browser is called, it will pause for $sleep seconds (or 15 seconds if $sleep is not defined), to give the user time to log in. The method returns the session token created by "create_token".

Implementation of the auth.expireSession function. 

    $result = $client->auth->expire_session();
Implementation of the auth.promoteSession function. 

    $result = $client->auth->promote_session();
Implementation of the auth.revokeAuthorization function. 

    $result = $client->auth->revoke_authorization();
Implementation of the auth.revokeExtendedPermission function. 

    $result = $client->auth->revoke_extended_permission(
                    perm => 'email',
                    uid  => $uid
    );
Sends a POST to http://www.facebook.com/logout.php, with the parameter "confirm" set to 1 (Cf. http://developers.facebook.com/documentation.php?v=1.0&doc=auth )

_use_http_uri()
Makes the WFA object's server URI scheme http. Uses "_flip_scheme".
_use_https_uri()
Makes the WFA object's server URI scheme https. Uses "_flip_scheme".
_flip_scheme( $make_https )
If $make_https is true, the scheme becomes https. If false, the scheme becomes http. The WFA object's "server_uri" attribute is then set to use that scheme.

You are running a desktop app and you did not pass a token into get_session. You can create a token by calling create_token() or (better) login().

You are running a web app and the user hasn't logged in to Facebook for your web app. When the user does so, an auth_token will be returned (as a parameter) to your callback url. Use that auth_token for the session.

The module doesn't know the command to use to open a browser on the given system. If you passed in "browser" to login(), it can use that string as the command to execute to open the login url.
The login() method is not able to be used to sign in when using a web app. See the Facebook TOS A.9.iv.

WWW::Facebook::API::Auth requires no configuration files or environment variables.
