AuthController在另一個模塊

Question

我在使用驗證在ZF2：

這是一個控制器

<?php 

namespace Admin\Controller; 

use Zend\Mvc\Controller\AbstractActionController; 
use Zend\Form\Annotation\AnnotationBuilder; 
use Zend\View\Model\ViewModel; 
use Admin\Model\User; 

class AuthController extends AbstractActionController { 

    protected $form; 
    protected $storage; 
    protected $authservice; 

    public function getAuthService() { 
     if (!$this->authservice) { 
      $this->authservice = $this->getServiceLocator()->get('AuthService'); 
     } 

     return $this->authservice; 
    } 

    public function getSessionStorage() { 
     if (!$this->storage) { 
      $this->storage = $this->getServiceLocator()->get('Admin\Model\MyAuthStorage'); 
     } 

     return $this->storage; 
    } 

    public function getForm() { 
     if (!$this->form) { 
      $user = new User(); 
      $builder = new AnnotationBuilder(); 
      $this->form = $builder->createForm($user); 
     } 

     return $this->form; 
    } 

    public function loginAction() { 
     //if already login, redirect to success page 
     if ($this->getAuthService()->hasIdentity()) { 
      return $this->redirect()->toRoute('success'); 
     } 

     $form = $this->getForm(); 

     return array(
      'form' => $form, 
      'messages' => $this->flashmessenger()->getMessages() 
     ); 
    } 

    public function authenticateAction() { 
     $form = $this->getForm(); 
     $redirect = 'login'; 

     $request = $this->getRequest(); 
     if ($request->isPost()) { 
      $form->setData($request->getPost()); 
      if ($form->isValid()) { 
       //check authentication... 
       $this->getAuthService()->getAdapter() 
         ->setIdentity($request->getPost('username')) 
         ->setCredential($request->getPost('password')); 

       $result = $this->getAuthService()->authenticate(); 
       foreach ($result->getMessages() as $message) { 
        //save message temporary into flashmessenger 
        $this->flashmessenger()->addMessage($message); 
       } 

       if ($result->isValid()) { 
        $redirect = 'success'; 
        //check if it has rememberMe : 
        if ($request->getPost('rememberme') == 1) { 
         $this->getSessionStorage() 
           ->setRememberMe(1); 
         //set storage again 
         $this->getAuthService()->setStorage($this->getSessionStorage()); 
        } 
        $this->getAuthService()->setStorage($this->getSessionStorage()); 
        $this->getAuthService()->getStorage()->write($request->getPost('username')); 
       } 
      } 
     } 

     return $this->redirect()->toRoute($redirect); 
    } 

    public function logoutAction() { 
     if ($this->getAuthService()->hasIdentity()) { 
      $this->getSessionStorage()->forgetMe(); 
      $this->getAuthService()->clearIdentity(); 
      $this->flashmessenger()->addMessage("Logout done."); 
     } 

     return $this->redirect()->toRoute('login'); 
    } 

} 

當我嘗試使用此控制器在另一個模塊中「信息例如」它返回一個錯誤消息：

使用

use Admin\Controller\AuthController; 

public function indexAction() { 

    $getAuth = new AuthController(); 

    $getAuth->getServiceLocator()->get('AuthService')->hasIdentity(); 

    $authService = $getAuth->getAuthService(); 
    if ($authService->hasIdentity()) { 
     echo 'Auth area'; 
    } 
} 

錯誤消息回報是：

Fatal error: Call to a member function get() on a non-object in .....\Controller\PostsController.php on line 31

Line 31 mean: $getAuth->getServiceLocator()->get('AuthService')->hasIdentity();

什麼問題？

Answer 1

服務定位器不是在你的AuthController注入，所以你不明白這一點，呼籲$getAuth對象這將導致該get()功能不起作用getServiceLocator()功能。

使用$this->getServiceLocator()->get('AuthService')->hasIdentity();

正如Tomdarkness表示，其做法不好，只是想你在這裏告訴你應該如何解決你的代碼和什麼`壞。

看看這個鏈接getting dependencies into zf2 controllers你如何做構造函數注入你的服務定位器。
