擴展的UserManager在Symfony2中與FOSUserBundle

Question

我試圖根據這個link

我的服務就是正確檢測延長FOS的的UserManager，但我有一個錯誤，我不能解析：

ErrorException: Catchable Fatal Error: Argument 1 passed to FOS\UserBundle\Entity\UserManager::__construct() must be an instance of Symfony\Component\Security\Core\Encoder\EncoderFactoryInterface, none given, called in 

MyUserManager：

namespace ChoupsCommerce\UserBundle\Model; 

use FOS\UserBundle\Entity\UserManager; 
use Symfony\Component\Security\Core\Exception\UsernameNotFoundException; 

class MyUserManager extends UserManager 
{ 
    public function loadUserByUsername($username) 
    { 
     $user = $this->findUserByUsernameOrEmail($username); 

     if (!$user) { 
      throw new UsernameNotFoundException(sprintf('No user with name "%s" was found.', $username)); 
     } 

     return $user; 
    } 
} 

Answer 1

您需要添加類的構造方法（__construct），並通過必要的參數下到基類：

namespace ChoupsCommerce\UserBundle\Model; 

use Doctrine\ORM\EntityManager; 
use FOS\UserBundle\Entity\UserManager; 
use Symfony\Component\Security\Core\Encoder\EncoderFactoryInterface; 
use FOS\UserBundle\Util\CanonicalizerInterface; 

class MyUserManager extends UserManager 
{ 
    public function __construct(
     EncoderFactoryInterface $encoderFactory, 
     CanonicalizerInterface $usernameCanonicalizer, 
     CanonicalizerInterface $emailCanonicalizer, 
     EntityManager $em, 
     $class 
    ) { 
     parent::__construct($encoderFactory, $usernameCanonicalizer, $emailCanonicalizer, $em, $class); 
    } 
} 

Answer 2

對不起，我的英文很差。

可能是您的自定義管理器服務的論點是錯誤的，因爲它說

Argument 1 passed to FOS\UserBundle\Entity\UserManager::__construct() must be an instance of Symfony\Component\Security\Core\Encoder\EncoderFactoryInterface, none given, called in

這裏是我的配置：

iep_core.iep_user_manager: 
    class: Iep\CoreBundle\Service\IepUserManager 
    arguments: [@security.encoder_factory, @fos_user.util.username_canonicalizer, @fos_user.util.email_canonicalizer, @fos_user.entity_manager, Iep\CoreBundle\Entity\User] 

Answer 3

我有同樣的問題，這裏是我的解決方案（基本上是前兩個答案的組合）：

在config.yml中設置服務，不要忘記參數

services: 
    custom_user_manager: 
     class: Acme\UserBundle\Model\CustomUserManager 
     arguments: [@security.encoder_factory, @fos_user.util.username_canonicalizer, @fos_user.util.email_canonicalizer, @fos_user.entity_manager, Acme\UserBundle\Entity\User] 

然後服務連接到FOS user_manager（也config.yml）：

fos_user: 
    service: 
     user_manager: custom_user_manager 

在CustomUserManager召回構造法，像gilden說：

class CustomUserManager extends UserManager{ 

    public function __construct(EncoderFactoryInterface $encoderFactory, CanonicalizerInterface $usernameCanonicalizer, CanonicalizerInterface $emailCanonicalizer, ObjectManager $om, $class) 
    { 
     parent::__construct($encoderFactory, $usernameCanonicalizer, $emailCanonicalizer, $om, $class); 
    } 

}
