我如何注入「用戶會話」模式以觀察員在Magento 2

我有注射\ Magento的\用戶\型號\會議模式進入我的觀察者的麻煩。我得到一個「循環依賴」錯誤。有任何想法嗎？我如何注入「用戶會話」模式以觀察員在Magento 2

的想法是強制在所有前端頁面登錄。我已成功注入URL接口以獲取當前URL和HTTP類，以將來賓用戶重定向到登錄頁面。

唯一缺少的一塊，現在是客戶會話模型。

這裏是我的代碼：

<?php 

/** 
* Namespace 
*/ 
namespace VendorName\CustomerLoginRedirect\Observer; 

/** 
* Dependencies 
*/ 
use Magento\Framework\Event\ObserverInterface; 
use Magento\Framework\Event\Observer; 

/** 
* Observer Class 
*/ 
class CustomerInit implements ObserverInterface { 
    /** 
    * Constructor 
    */ 
    protected $_url; 
    protected $_http; 
    protected $_session; 

    public function __construct(
     \Magento\Framework\UrlInterface $url, 
     \Magento\Customer\Model\Session $session, 
     \Magento\Framework\App\Response\Http $http 
    ) { 
     $this->_url = $url; 
     $this->_session = $session; 
     $this->_http = $http; 
    } 

    /** 
    * Manages redirect 
    */ 
    public function execute(Observer $observer) { 
     $url = $this->_url->getCurrentUrl(); 
     $path = parse_url($url, PHP_URL_PATH); 

     // Allowed strings to match against URL 
     $allow = [ 
      '/customer' 
     ]; 

     // Ignore customer pages 
     foreach ($allow as $s) { 
      if (stripos($path, $s) !== false) { 
       return; 
      } 
     } 

     // Check if customer logged in 
     // if ($this->_session->isLoggedIn()) { 
     //  die('Is logged in!!'); 
     //  return; 
     // } 

     return; 

     // Redirect to login 
     $this->_http->setRedirect($this->_url->getBaseUrl().'customer/account/login/', 301); 
    } 
}

以下是錯誤消息：

Circular dependency: VendorName\CustomerLoginRedirect\Observer\CustomerInit depends on VendorName\CustomerLoginRedirect\Observer\CustomerInit and vice versa.

的\ Magento的\用戶\型號\會議模型無法注入的觀察員「visitor_init」和「customer_session_init」事件。

我現在使用的「controller_action_predispatch」，可以成功地注入客戶會話模式

這裏是我的模塊的等/前端/ events.xml：

<?xml version="1.0" encoding="UTF-8"?> 
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:Event/etc/events.xsd"> 
    <event name="controller_action_predispatch"> 
     <observer 
      name="vendorname_controller_action_predispatch" 
      instance="VendorName\ForceLogin\Observer\ControllerPredispatch" /> 
    </event> 
</config>

的sooo ..匝開展「customer_session」對象在我的觀察中$observer對象中是可用的。在我方法，我所做的：

public function execute(Observer $observer) { 
    $session = $observer->getCustomerSession(); 
    if ($session->isLoggedIn()) { 
     return; 
    } 
}

在其他事件掛鉤，如「controller_action_predispatch」，該customer_session對象不可用。我發現了另一種方法，如果客戶在使用HTTP Context對象登錄：

/** 
* Observer Dependencies 
*/ 
use Magento\Framework\Event\ObserverInterface; 
use Magento\Framework\Event\Observer; 

class ControllerPredispatch implements ObserverInterface { 
    protected $_context; 

    public function __construct(
     \Magento\Framework\App\Http\Context $context 
    ) { 
     $this->_context = $context; 
    } 

    public function execute(Observer $observer) { 
     $loggedIn = $this->_context->getValue(\Magento\Customer\Model\Context::CONTEXT_AUTH); 
     if ($loggedIn) { 
      return; 
     } 
    } 
}
