Trying to have access to route parameters inside group routing - php

Question

I'm trying to have access to {module} inside my function, but it returns me the following error :
Too few arguments to function {closure}(), 1 passed in /Users/Bernard/PROJECTS/myproject/vendor/laravel/lumen-framework/src/Routing/Router.php on line 62 and exactly 2 expected
Here's my code :
$app->router->group([
'namespace' => 'App\Http\Controllers',
], function ($router) {
$router->group([
'namespace' => $version,
'prefix' => "api/$version/{contest}/{module}",
'middleware' => 'App\Http\Middleware\COMMON\DefineContest',
], function ($request, $module) use ($router) {
dd($module);
require __DIR__ . "/../routes/v1/{module}.routes.php";
});
});

Answer 1

In Laravel, it would be as simple as calling Illuminate\Support\Facades\Route::parameter(paramname) but since it is apparently not available in Lumen(looking at Lumen Router there are no methods or parameters for this use case), this is an imperative answer that does get the job done:
$version = 1;
$router->group([
'namespace' => 'App\Http\Controllers',
], function ($router) use ($version) {
$router->group([
'namespace' => $version,
'prefix' => "api/$version/{contest}/{module}",
'middleware' => 'App\Http\Middleware\COMMON\DefineContest'
], function ($router) use ($version) {
$url = $_SERVER['REQUEST_URI'];
if (preg_match("/api\/$version\/(?<contest>\w+)\/(?<module>\w+)/", $url, $output)) {
$module = $output['module'];
dd($module);
}
});
});
I should point out that this code results in an extra step for every route which I don't think matters since it's not that heavy but something to note of.
