handle get request in controller action

Question

In a custom payement gateway, where the store redirects to third party website for payment. To request i have options to send either in POST/GET. I'm requesting with POST method. But the response they give is in get method.

The response url according to their documentation is http://yoursite.com/success?q=su&oid=XYZ1234&amt=100&refId=000AE01

And in my case i have captured response at http://yoursite.com/cgateway/payment/response with responseAction method of PaymentController.php controller.

The result i obtained is http://yoursite.com/cgateway/payment/response?q=su&oid=XYZ1234&amt=100&refId=000AE01

Now the problem is how should i get those data in responseAction in PaymentController ?

Answer 1

To get params in a controller you can use:

$this->getRequest()->getParam('paramName');

or

$this->getRequest()->getParams();

Answer 2

Magento's default routing algorithm uses three part URLs.

http://example.com/front-name/controller-name/action-method

So when you call

http://example.com/path/action/id/123

The word path is your front name, action is your controller name, and id is your action method. After these three methods, you can use getParam to grab a key/value pair

http://yoursite.com/cgateway/payment/response?q=su&oid=XYZ1234&amt=100&refId=000AE01
//in a controller
var_dump($this->getRequest()->getParams('q'));

You may also use the getParams method to grab an array of parameters

$this->getRequest()->getParams();

Hope this helps
