Symfony组件 - 路由

Question

问题：

说真的，我用得好吗？它有效，但我不确定使用Symfony组件的正确方法。有人像我一样使用这些组件吗？

1. 我不确定dispatch（）
中的异常处理
2. 我不确定在下面的代码中使用$ _SERVER [＆＃39; REQUEST_URI＆＃39;] ...

我的 composer.json

{
    "require": {
        "symfony/routing": "^3.2"
    }
}

我的 index.php

<?php

include './vendor/autoload.php';

use Symfony\Component\Routing\Exception\MethodNotAllowedException;
use Symfony\Component\Routing\Exception\ResourceNotFoundException;
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;

class Christopher {
    public $context;
    public $routes;

    public function __construct() {
        $context = new RequestContext();
        $this->context = $context->fromRequest(Request::createFromGlobals());
        $this->routes = new RouteCollection();
    }

    public function route($methods, $path, $controller) {
        $this->routes->add($path, new Route(
            $path,
            [
                '_controller' => $controller
            ],
            [
                'id' => '[0-9]'
            ],
            [],
            '',
            [],
            $methods
        ));
    }

    public function dispatch() {
        $matcher = new UrlMatcher($this->routes, $this->context);

        try {
            $matcher = $matcher->match($_SERVER['REQUEST_URI']);

            call_user_func_array($matcher['_controller'], array_slice($matcher, 1, -1));
        } catch (MethodNotAllowedException $e) {
            echo 'Route method is not allowed.';
        } catch (ResourceNotFoundException $e) {
            echo 'Route does not exist.';
        }
    }
}

$christopher = new Christopher();

$christopher->route('GET', '/posters', function () {
    echo '<a href="/posters/1">1. Poster</a>';
});

$christopher->route('GET', '/posters/{id}', function ($id) {
    echo 'ID - ' . $id;
});

$christopher->dispatch();
