How do you get request body data in controller?

[eluser]SpudNik[/eluser]
I was able to get this working by using

Code:

$jsonArray = json_decode(file_get_contents('php://input'),true);

The above will read the request body from the input request and then decodes the JSON to an associative array.

I would still be interested in refactoring this code if CI has a wrapper for reading input stream data as I am above. Fairly new to this framework.
Thanks for the replies.
