Reading a HttpRequest post data on OpenCart

Question

I am sending a HTTP request from a C# windowsform application to an OpenCart store.

This is what fiddler is showing that I'm sending, which looks correct.

This is the code I have in my OpenCart project that I'm calling.

class ControllerEAOpenCartProducts extends ControllerEAOpenCart {

   public function createProduct()
    {
        print_r($this->request);
    }
}

The print_r is outputting the following data which doesn't appear to be containing any of my JSON data.

The content type of the requst also seems to be incorrect, shouldn't it be application/json like the request in fiddler shows?

Content-Type: text/html

Looks like opencart's request class wraps php's globals. These only get populated when regular form data is submitted.

To access json, you need to use the lower level input stream:

public function createProduct()
{
    print_r(json_decode(file_get_contents('php://input'), true));
}
