Get Post Data from drupal_http_request I have two websites use Drupal.

In Websites ONE:  I have code

$data = array(
  'key1' =&gt; 'value1',
  'key2' =&gt; 'value2',
);
$request = array(
  'headers' =&gt; array(
    'Content-Type' =&gt; 'application/json',
    'Accept' =&gt; 'application/json',
  ),
  'data' =&gt; drupal_json_encode($data),
  'method' =&gt; 'POST',
  'max_redirects' =&gt; 3,
  // We set a lower timeout since we don't want the user waiting for the page too long
  'timeout' =&gt; 30,
);

$url = 'http://examplesitetwo.com/return-data';
$response = drupal_http_request($url, $request);


In Website TWO: i have code

function my_module_menu() {
  $items = array();

  $items['return-data'] = array(
    'page callback' =&gt; 'return_data_pcb',
    'access arguments' =&gt; array('access content'),
    'type' =&gt; MENU_CALLBACK,
  );
  return $items;
}

function return_data_pcb() {
  // How to get post data form drupal_http_request in website one;
}


How to get post data form drupal_http_request() in website one? Thank you!
Sorry. It's not answer. But i try debug in function 

function return_data_pcb() {
  watchdog("debug", '&lt;pre&gt;' . print_r( $_POST, true) . '&lt;/pre&gt;'); 
  // But $_POST is empty array. It's show in admin/reports/dblog, when in website one // call function drupal_http_request.
}


I don't know my problem by when call drupl_http_request data post doesn't not send. Or problem with hook_menu in website two. Please help!
