My project requires me to know what file extension was used while calling a route.
For example, If the route was 127.0.0.1/controller/action/filea.json Then then I would need to have a function that returns ".json" when called from inside action function "get_action".
If the route was 127.0.0.1/controller/action2/fileb.xml Then then the function should return ".xml" when called from inside action function "get_action2".
Right now, I tried using \URI::current(), but that only gets me "127.0.0.1/controller/action/filea" or "127.0.0.1/controller/action2/fileb"
Whether or not the extension is used is controlled by the config key routing.strip_extension, which is true by default.
The current extension can be retrieved using \Input::extension().
