Symfony路由器UrlMatcher中match参数与RequestContext的区别

use Symfony\Component\Routing\Route;
use Symfony\Component\Routing\RouteCollection;
use Symfony\Component\Routing\Matcher\UrlMatcher;

$routes = new RouteCollection();
$routes->add('home', new Route('/home', ['_controller' => 'HomeController::index']));
$routes->add('profile', new Route('/profile/{id}', ['_controller' => 'ProfileController::show']));

$matcher = new UrlMatcher($routes, new RequestContext());
$result = $matcher->match('/profile/123');

use Symfony\Component\Routing\Generator\UrlGeneratorInterface;
use Symfony\Component\Routing\RequestContext;
use Symfony\Component\Routing\RouteCollection;
use Symfony\Component\Routing\Generator\UrlGenerator;

$routes = new RouteCollection();
$routes->add('home', new Route('/home', ['_controller' => 'HomeController::index']));
$routes->add('profile', new Route('/profile/{id}', ['_controller' => 'ProfileController::show']));

$generator = new UrlGenerator($routes, new RequestContext());
$url = $generator->generate('profile', ['id' => 123]);
