Question

我想添加一个按用户数据重定向的流程例如，它是一个积分系统如果用户没有积分，则强制重定向到静态页面。

我在脑海中想要添加构建公共BaseController函数的过程。

class BaseController extends Controller
{
    public function __construct()
    {
        if ($this->container->get('security.context')->isGranted('IS_AUTHENTICATED_REMEMBERED')) {
            $user    = $this->container->get('security.context')->getToken()->getUser();
            $manager = $this->container->get('doctrine')->getManager();

            if (! $manager->getRepository('MyUserBundle:User')->hasPoints($user))
                return new RedirectResponse($this->container->get('router')->generate('static_page_route'));
        }
    }

但我不能使用容器。

错误：在非对象上调用成员函数get（）

争议点：
1.如何在构造函数中使用用户对象 2.根据用户数据的状态（如点），是否有更简单的重定向过程方法？（虽然我仍然不知道ACL细节，但是通过用户点状态更改角色。）

添加示例：

public function onKernelRequest(GetResponseEvent $event){
    if (!$this->securityContext->getToken()) {
        return;
    }

    $isUser = $this->securityContext->isGranted('ROLE_USER');

    if (!$isUser) {
        return;
    }

    $user    = $this->securityContext->getToken()->getUser();
    $request = $event->getRequest();
    $_route  = $request->attributes->get('_route');

    if (! $user->hasPoints() && $_route != 'static_page_route') {
        // exit; <= page rendering is done even if process exit.
        //          Redirect process be called after rendering?
        $redirectUrl = $this->router->generate('static_page_route');
        $event->setResponse(new RedirectResponse($redirectUrl));     // <= `The page isn't redirecting properly` error now.
    }
}

一个解决方案：

<?php

namespace My\ExampleBundle\EventListener;

use Symfony\Component\HttpFoundation\RedirectResponse;
use Symfony\Bundle\FrameworkBundle\Routing\Router;
use Symfony\Component\Security\Core\SecurityContext;
use Symfony\Component\HttpKernel\Event\GetResponseEvent;
use Symfony\Component\HttpKernel\HttpKernel;

class BeforeController {
    protected $securityContext;

    protected $router;

    public function setRouter(Router $router){
        $this->router = $router;
    }

    public function setSecurityContext(SecurityContext $securityContext){
        $this->securityContext = $securityContext;
    }

    public function onKernelRequest(GetResponseEvent $event){
        if (HttpKernel::MASTER_REQUEST != $event->getRequestType()) { return; }
        if (! $this->securityContext->getToken()) { return; }
        if (! $this->securityContext->isGranted('ROLE_USER')) { return; }

        $user    = $this->securityContext->getToken()->getUser();
        $request = $event->getRequest();
        $_route  = $request->attributes->get('_route');

        if (! $user->hasPoints() && $_route != 'static_page_route') {
            $redirectUrl = $this->router->generate('static_page_route');
            $event->setResponse(new RedirectResponse($redirectUrl));
        }
    }
}

根据Symfony2中用户数据的状态，一种更简单的重定向过程
