Using symfony / routing, need to implement routing for the MVC application. Using the whole Symfony is prohibited, only the library. Controller class:
namespace App\Controllers;
use App\Core\Controller;
class IndexController extends Controller {
public function IndexAction(){
$this->View->render('index');
}
}
view class:
namespace App\Core;
namespace App\Core;
class View{
public function render($viewName) {
$viewAry = explode('/', $viewName);
$viewString = implode(DS, $viewAry);
if(file_exists('View/site' . $viewString . '.php')) {
require 'View/site' . $viewString . '.php';
} else {
die('The view \"' . $viewName . '\" does not exist.');
}
}
}
and Index.php itself from which it all starts:
use App\Controllers\IndexController;
use App\Core\Routing;
use Symfony\Component\Routing\Generator\UrlGenerator;
use Symfony\Component\Routing\Matcher\UrlMatcher;
use Symfony\Component\Routing\RequestContext;
use Symfony\Component\Routing\Route;
use Symfony\Component\Routing\RouteCollection;
use Symfony\Component\HttpFoundation\Request;
use Symfony\Component\Routing\Loader\Configurator\RoutingConfigurator;
use App\Core\Application;
use Symfony\Component\Routing\Router;
require __DIR__ . '/vendor/autoload.php';
$collection = new RouteCollection();
$collection->add('index', new Route('/', array(
'_controller' => [IndexController::class, 'IndexAction']
)));
return $collection;
As a result of a request to the application through the postman, I get nothing, what's the problem?
In your front controller you are just defining the routes, but not actually processing the request, matching it to a controller or invoking it.
There is a section on this topic in the manual , it uses more symfony components, but can be of help.
You'd have to determine the requested route directly from PATH_INFO
instead of using the HttpFoundation
component, and then try to match the request to a route.
Here is a very crude implementation:
$collection = new RouteCollection();
$collection->add('index', new Route('/', array(
'_controller' => [IndexController::class, 'IndexAction']
)));
$matcher = new UrlMatcher($collection, new RequestContext());
// Matcher will throw an exception if no route found
$match = $matcher->match($_SERVER['PATH_INFO']);
// If the code reaches this point, a route was found, extract the corresponding controller
$controllerClass = $match['_controller'][0];
$controllerAction = $match['_controller'][1];
// Instance the controller
$controller = new $controllerClass();
// Execute it
call_user_func([$controller, $controllerAction]);
