[osflash] AMFPHP vs SabreAMF vs WebORB

[Evert | Rooftop]

Hi João,

The roles feature in sabreamf isn't as easily done as with amfphp, for 
example. The idea is that you can catch authentication (both amf0/amf3) 
and implement your own roles-system. The added benefit is that you can 
for example implement an acl list, backed with a database...

Any development with sabreamf starts with making your own 
'serviceinvoker' class which handles the business logic of an amf0/3 call..

You'll find a pretty good one on 
http://www.adobe.com/devnet/flex/articles/remoteobject_sabreamf.html, 
which also handles VO-mappings..

This is a really basic invoker which handles authentication and access 
control (10% pseudo code)

Service-invoker :

class MyServiceInvoker {

  protected $username;
  protected $loggedIn = false;

  function exec() {

     $s = new SabreAMF_CallbackServer();
     $s->onAuthenticate = array($this,'authenticate');
     $s->onInvokeService = array($this,'invokeService');

  }

  function authenticate($username,$password) {

    // do a login operation here.. throw an exception if you want to 
make this fail
    $this->username = $username;
    $this->loggedIn = true;

  }

  function invokeService($service,$method,$arguments) {

      // first check if the current user has the correct permissions to 
invoke the method
      // if not, throw an exception

      // Most likely you want to load a class after that, and call its 
method with
      // return call_user_func_array(array($object,$method),$arguments);

  }

}
