Headers based routing with Slim 3

I have a Slim 3 route: $app->get('/calendar/{date}', 'CalendarCtrl:getSchedule');
This route can return the same schedule by simple HTML list, json or xml format.
Now I'm looking for a simple REST solution based on Accept (or more headers) HTTP header.

For example:
Request: 

GET /calendar/2017-01-01  
Accept: application/json

Response:

Content-Type: application/json
Body: {json schedule}

So a route should be smth like this: $app->get('/calendar/{date}', {Accept: application/json}, 'CalendarCtrl:getScheduleJson');

I know I can check for that header in a route handler. But I'm looking for a simple declarative solution.

Add a middleware to check for that header before sending the response from your API 

$app->add(function ($req, $res, $next) {
//Checking for $req content-type here then send the response with the same one 
//example 
$headerValue= $req->getHeader('Accept');
if($headerValue=='application/json')
{
  $response = $next($req, $res);
    return $response
            ->withHeader('Content-type', 'application/json');
 }
else{

//check for other header here  
}      
});
