Add the below catch-all route to the bottom of your routes.php and remember to run composer dump-autoload afterwards. Notice the use of "->where" that specifies the possible content of params, enabling you to use a param containing a slash.
//routes.php Route::get('view/{slashData?}', 'ExampleController@getData') ->where('slashData', '(.*)');
And than in your controller you just handle the data as you'd normally do (like it didnt contain the slash).
//controller class ExampleController extends BaseController { public function getData($slashData = null) { if($slashData) { //do stuff } } }
This should work for you.
Additionally, here you have detailed Laravel docs on route parameters: [ docs ]
