如何在magento2中获取当前客户组ID

我想在phtml文件中获取当前的客户组ID。当我仍未登录时，将返回一般类型的客户组。如何获得适当的输出？

Magento\Customer\Model\Session $customerSession 使用此类，您将获得当前的客户组ID

protected $_customerSession;

public function __construct(
        \Magento\Customer\Model\Session $customerSession,
    ) {
        $this->_customerSession = $customerSession;
    }

public function getGroupId(){
 if($this->_customerSession->isLoggedIn()):
        echo $customerGroup=$this->_customerSession->getCustomer()->getGroupId();
    endif;
}

注意：只有在客户登录后，您才能获得客户ID

您可以通过以下代码获取组ID

protected $_customerSession;

public function __construct(
        ....    
        \Magento\Customer\Model\Session $customerSession,
        ....
    ) {


        $this->_customerSession = $customerSession;

    }

public function getGroupId(){
 if($this->_customerSession->isLoggedIn()):
        echo $customerGroup=$this->_customerSession->getCustomer()->getGroupId();
    endif;

}

默认情况下，Magento将清除客户会话：\Magento\PageCache\Model\Layout\DepersonalizePlugin::afterGenerateXml。

/magento//a/92133/33057

看一看：

供应商/ magento /模块客户/模型/Context.php

/**
 * Customer group cache context
 */
const CONTEXT_GROUP = 'customer_group';
/**
 * Customer authorization cache context
 */
const CONTEXT_AUTH = 'customer_logged_in';

我们可以检查已登录的客户和客户组：

 /**
 * @var \Magento\Framework\App\Http\Context $httpContext
 */
$isLogged = $this->httpContext->getValue(Context::CONTEXT_AUTH);
$customerGroupId = $this->httpContext->getValue(Context::CONTEXT_GROUP);

将这些代码行放在您的块中。

这里还有另一个很好的解释：

https://ranasohel.me/2017/05/05/how-to-get-customer-id-from-block-when-full-page-cache-enable-in-magento-2/

尝试此操作以获取已登录和未登录客户的当前客户组ID和名称

protected $_customerSession;

protected $_customerGroupCollection;

public function __construct(
    ....    
    \Magento\Customer\Model\Session $customerSession,
    \Magento\Customer\Model\Group $customerGroupCollection,
    ....
) {


    $this->_customerSession = $customerSession;
    $this->_customerGroupCollection = $customerGroupCollection;

}

public function getCustomerGroup()
{
        echo $currentGroupId = $this->_customerSession->getCustomer()->getGroupId(); //Get current customer group ID
        $collection = $this->_customerGroupCollection->load($currentGroupId); 
        echo $collection->getCustomerGroupCode();//Get current customer group name
}

protected $_customerSession;

public function __construct(
        \Magento\Customer\Model\Session $customerSession,
    ) {
        $this->_customerSession = $customerSession;
    }

public function getGroupId(){
 if($this->_customerSession->isLoggedIn()):
        echo $customerGroup=$this->_customerSession->getCustomer()->getGroupId();
    endif;
}

这可能对您有用。

如果使用缓存，则使用\ Magento \ Customer \ Model \ Session可能会失败。

您最好使用：

private $sessionProxy;

public function __construct(
    use Magento\Customer\Model\Session\Proxy $sessionProxy,
) {
    $this->sessionProxy= $sessionProxy;
}

// may return groupId or \Magento\Customer\Model\GroupManagement::NOT_LOGGED_IN_ID  
public function getGroupId(){
   $this->sessionProxy->getCustomer()->getGroupId();
}
