slim optional route parameter suffix not working -

i want define route have .suffix param in end. want use in app return user needs. eg .json or .xml or none!. how should define route? example address want:

/user/all.json 

or

/user/all.xml 

or

/user/all # default json 

this route defined. it's not working expected.

/user/:method(\.(:type)) 

in slim route segments defined forward slash, , not interchangeably dot. however, can either add logic route closure, or add route conditions multiple routes.

in closure:

$app->get('/user/:methodtype', function ($methodtype) {     if ($path = explode($methodtype, '.')) {         if ($path[1] === 'json') {             // json...         } elseif ($path[1] === 'xml') {             // xml...         }     } }); 

or use route conditions, 1 each mutually exclusive:

// json requests $app->get('/user/:methodtype', function ($methodtype) {     // json... })->conditions(array('methodtype' => '.json$'));  // xml requests $app->get('/user/:methodtype', function ($methodtype) {     // xml... })->conditions(array('methodtype' => '.xml$'));
