title: Receive HTTP POST in Controller of my Magento Custom Module
body: <p>I'm learning to develop modules magento. I'm developing a payment module and it should receive a post (after closing the application) to change the status of the request and generate the invoice.</p>
  
  <p>But I do not know how to get on my HTTP POST controller. I will make a post at <a href="http://mymagento.com/mymodule/receive" rel="nofollow">http://mymagento.com/mymodule/receive</a>.</p>
  
  <pre><code>class MyCompanyName_MyModule_StandardController extends Mage_Core_Controller_Front_Action{
  
      public function receiveAction() {
          //How receive my POST HERE??
      }
  
      // ...
  
  }
  </code></pre>
  
  <p>I appreciate any help</p>
