Slim Framework v3 - 与AND没有最终'/'的相同路由

Question

I created a small application with SlimFramework v3 and I am able to build a simple route like this:

// GET localhost/admin
$app->get('/admin', function(){
    # code here
});

My problem is that this work only for localhost/admin and not for localhost/admin/ (with final backslash). Is there any option to use ONE route for both?

Answer 1

There are 2 possibilities

1. Specify an optional /

   $app->get('/admin[/]', function(){
       # code here
   });
   

2. Add middleware that redirects routes with an ending / to the url without that.

   use Psr\Http\Message\RequestInterface as Request;
   use Psr\Http\Message\ResponseInterface as Response;
   
   $app->add(function (Request $request, Response $response, callable $next) {
       $uri = $request->getUri();
       $path = $uri->getPath();
       if ($path != '/' && substr($path, -1) == '/') {
           // permanently redirect paths with a trailing slash
           // to their non-trailing counterpart
           $uri = $uri->withPath(substr($path, 0, -1));
   
           if($request->getMethod() == 'GET') {
               return $response->withRedirect((string)$uri, 301);
           }
           else {
               return $next($request->withUri($uri), $response);
           }
       }
   
       return $next($request, $response);
   });
