Using QUERY_STRING on CI4

My first question would be, why would you even want to do this for the controllers and all the routing?

If you only want to get a value from the query string you can use getVar() or getGet():

PHP Code:

$something = $request->getVar('foo');
$something = $request->getGet('foo');

I know it's not the most convenient thing, but I'm migrating an application and I need to change a lot of URLs. Being able to keep the current routing is the best option for me
