I'm trying to intercept a controller returning a JSON object of
Magento\Framework\Controller\Result\Json class. The problem is that no matter if I use a plugin or a preference to "catch" the controller response right after it's created to do what I want with it, I always end up with this
Json object, and its only public method inherited from
Magento\Framework\Controller\AbstractResult is the
renderResult method (apart from some setters, which won't help me at all).The JSON string is also a protected property, so I can't access it directly.
So, how can I get the JSON string from the response object? Of course, I could just replicate some of the controller's logic that creates it and use that instead, but I'm trying to avoid this method if possible.
