simple Services parameter question

hi Rolf,

thanks for the answer.

I'm currently not using Drupal 7 but Drupal 6. I need a list of nodes info (i'm not sure if REST server can handle multiple nodes at the same request?). About services, would you recommend me to upgrade to Drupal 7? (I'm just starting)

I'm currently creating a JSON using the code below; I would like to make a very simple thing: pass a parameter to this Service module, so that the info can be classified depending on user request. I assume this param can be sent on the URL calling the method, so I can get it in the module using $_GET['my param']

I'm trying to test using cURL, but I suppose that before calling my method I have to autenticate, right?

Following the code below I get a 'cannot login' message; which could be the reasons for that? permissions maybe? in error_drupal.log i get a 'closed keepalive connection'; cURL works, as I can see the HTML outside Drupal, but authentification fails.

I have followed http://drupal.org/node/322530 and http://drupal.org/node/86727

If I could finally log in, how could I call the module via URL? could I add to this URL the parameter I need? ex: http://...../mymodule?param=X

thank you very much for the patience!
