Tools for testing the server

Browser tools

• The Poster add-on for Firefox.
• The RESTClient add-on for Firefox.
• The HttpRequester add-on for Firefox.
• The REST Console app for Chrome.

• The API Kitchen (web-based or Mac download...the download version is not working properly for user login but the web-based one is)

Drupal modules

• The function drupal_http_request() is part of Drupal core.
  You can simple use some custom code such as this:

  $account = array(
    'name' => 'test_user',
    'pass' => 'xyzzy',
    'mail' => 'test_user@xyzzy.com',
  );
  $response = drupal_http_request($url, $headers, 'POST', http_build_query($account, '', '&'));
  

• The HTTP Client module provides a client library for Drupal that is designed to work with Services.
• There is also the Web service Client module providing a nice interface.

Command line

If you prefer working from the command line, you can also use CURL. See this starter tutorial
