Zend Framework 2在视图助手中获取身份

Question

I need to display the user cart amount on each page of an e-shop application.

To achieve that, I have created a view helper but I don't know how to get the user's identity ...

<?php

namespace ...;

use ...\Services\Traits\OrdersServicesTrait;
use Zend\View\Helper\AbstractHelper;

class CartAmount extends AbstractHelper {

    use OrdersServiceTrait;

    public function __invoke()
    {

        // needs identity here ...

        $amount = $this->getOrdersService()->fetchCartAmount($user);

        if (!$amount)
            return 0;

        return $amount;
    }

}

Appreciate your help

通常，这里需要一个依赖项注入示例，但是在这种情况下， $this->view->identity() （调用身份视图帮助器）应该可以为您提供帮助。
