request to response

In practice session: we planned to create comment from client side, so we write a code using drupal_services_api.md.

Here the code is:

//planned to create comment in server from client.
$request_url = 'http://local.server.com/js-comment/cid';
$request_headers = array('Content-Type' => 'application/json');
$request_method = 'POST';
