fosuserbundle覆盖登录操作

Question

我正在使用FSOUserBundle,我想覆盖loginAction,我使用了这个方法:

namespace PjDZ\UserBundle\Controller;
use FOS\UserBundle\Controller\SecurityController as BaseController;

class SecurityController extends BaseController {

public function loginAction(\Symfony\Component\HttpFoundation\Request $request)
{
    /** @var $session \Symfony\Component\HttpFoundation\Session\Session */
    $session = $request->getSession();

    // get the error if any (works with forward and redirect -- see below)
    if ($request->attributes->has(SecurityContext::AUTHENTICATION_ERROR)) {
        $error = $request->attributes->get(SecurityContext::AUTHENTICATION_ERROR);
    } elseif (null !== $session && $session->has(SecurityContext::AUTHENTICATION_ERROR))    {
        $error = $session->get(SecurityContext::AUTHENTICATION_ERROR);
        $session->remove(SecurityContext::AUTHENTICATION_ERROR);
    } else {
        $error = '';
    }

    if ($error) {
        // TODO: this is a potential security risk (see http://trac.symfony-project.org/ticket/9523)
        $error = $error->getMessage();
    }
    // last username entered by the user
    $lastUsername = (null === $session) ? '' : $session->get(SecurityContext::LAST_USERNAME);

    $csrfToken = $this->container->has('form.csrf_provider')
        ? $this->container->get('form.csrf_provider')->generateCsrfToken('authenticate')
        : null;


    return $this->renderLogin(array(
        'last_username' => $lastUsername,
        'error'         => $error,
        'csrf_token' => $csrfToken,
    ));
}
}

但是当我尝试显示/登录页面时,我得到一个空白页面,任何想法？!! 原谅我糟糕的英语.

Answer 1

在Symfony版本3.3和Fosuserbundle版本2.1.0中,在config.yml中添加行之前,上述代码将不再起作用:

services:
    fos_user.security.controller:
      class: MAIN\MAINFOSUserBundle\Controller\SecurityController

    fos_user.resetting.controller:
      class: MAIN\MAINFOSUserBundle\Controller\ResettingController

    fos_user.profile.controller:
      class: MAIN\MAINFOSUserBundle\Controller\ProfileController

    fos_user.change_password.controller:
      class: MAIN\MAINFOSUserBundle\Controller\ChangePasswordController

这主要是因为我在composer.json中将friendsofsymfony保持最新

"friendsofsymfony/user-bundle": "~2.0@dev"

Answer 2

我通过使用修复错误:

namespace PjDZ\UserBundle\Controller;
use FOS\UserBundle\Controller\SecurityController as BaseController;

class SecurityController extends BaseController {
    public function loginAction(\Symfony\Component\HttpFoundation\Request $request){
        $response = parent::loginAction($request);

        //do something else;

        return $response;
     }
}

编辑:谢谢这解决了我的问题.请确保您不使用其他Basecontroller.以索引为例,像我一样.你会得到以下异常:

 Compile Error: Cannot use FOS\UserBundle\Controller\SecurityController as BaseController because the name is already in use 

我用了:

use FOS\UserBundle\Controller\SecurityController as FOSController;

class SecurityController extends FOSController
