正在使用联盟/路由将容器注入控制器

我正在使用联盟/路由，我想将我的容器注入控制器。这是我已经拥有的：

提供RouteCollection：

$this->getContainer()->share('route', function () {
    $route = require $this->getContainer()->get('baseDir').'/config/routes.php';
    return $route;
});

baseDir/config/routes.php:

<?php
use League'Route'Strategy'ParamStrategy;
use League'Container'ReflectionContainer;
$routes = (new 'League'Route'RouteCollection)
    ->setStrategy((new ParamStrategy)->setContainer(new ReflectionContainer));
    // The line above is here because ParamStrategy otherwise throws
    // Uncaught exception 'RuntimeException' with message 'To use the parameter strategy,
    // the container must implement the (::call) method.
$routes->get('/', 'Controller'PostController::index');
return $routes;

我的前控制器：

/** @var RouteCollection $route */
$route = $this->getContainer()->get('route');
/** @var ServerRequest $request */
$request = $this->getContainer()->get('request');
/** @var Response $response */
$response = $this->getContainer()->get('response');
/** @var SapiEmitter $emitter */
$emitter = $this->getContainer()->get('emitter');
$response = $route->dispatch($request, $response);
$emitter->emit($response);

我不知道应该在哪里调用控制器对象上的setContainer方法，因为它只存在于$route->dispatch($request, $response);中。将容器注入控制器的正确方法是什么？
