Magento 2以编程方式将产品添加到购物车时，迷你购物车产品价格变为零（$ 0.00）

Question

我创建了一个模块，用于以编程方式在循环中将产品添加到购物车中。当我们运行这个控制器代码时，它将在购物车页面显示价格的产品，但在迷你购物车显示产品价格为0.00美元。 我的控制器代码如下所示。

<?php

namespace Mageniks\Customaddtocart\Controller\Index;

use Magento\Framework\App\Action\Action;
use Magento\Framework\App\Action\Context;
use Magento\Framework\App\ResponseInterface;

    protected $quoteManagement;
    protected $_customerSession;
    protected $quoteFactory;
    public function __construct(Context $context,

        parent::__construct($context);
        $this->_resultPageFactory = $resultPageFactory;

         // Note : $products peramater contain all product information.
        $quote = $this->_checkoutSession->getQuote();
        foreach($products as $params)
        {
            $cartparams = array();

           $product = $this->_productloader->create()->load($productId);
            if (!$product) {
                return false;

            $customOptions = $this->_objectManager->get('Magento\Catalog\Model\Product\Option')->getProductOptionCollection($product);

                            $cartparams['options'][$option['option_id']] = "Color : black";
                    }
                    else if($option['title'] == "option2")
                    {


                            $cartparams['options'][$option['option_id']] = "Color : white";


                    }else
                    {
                        $cartparams['options'][$option['option_id']] = "";
                    }
                }



            if (isset($params['qty'])) {
                $cartparams['qty'] = $params['qty'];
            } else {
                $cartparams['qty'] = 1;
            }
            try {


                 $this->cart->addProduct($product, $cartparams);


            }catch (\Magento\Framework\Exception\LocalizedException $e) {
                if ($this->_checkoutSession->getUseNotice(true)) {
                    $this->messageManager->addNotice(
                        $this->_objectManager->get('Magento\Framework\Escaper')->escapeHtml($e->getMessage())
                    );
                } else {
                    $messages = array_unique(explode("\n", $e->getMessage()));
                    foreach ($messages as $message) {
                        $this->messageManager->addError(

                        );
                    }

            } catch (\Exception $e) {
                $this->messageManager->addException($e, __('We can\'t add this item to your shopping cart right now.'));
                $this->_objectManager->get('Psr\Log\LoggerInterface')->critical($e);
            }
            unset($params['product']);


        }
         $this->cart->getQuote()->setTotalsCollectedFlag(false)->collectTotals()->save();
         $this->cart->save();
        return true;
    }

}

我已经调试了所有的东西，但迷你购物车价格无法改变。在购物车页面中添加到购物车后显示为零。

请帮助我解决这个问题？

任何帮助都将不胜感激。

        return true;
    }

}

经过这么多谷歌或调试我找到了解决方案。我刚刚更改了设置为dataobject的params中的cart addProduct方法。请查看以下内容。

$request = new \Magento\Framework\DataObject();
$request->setData($cartparams);
$this->cart->addProduct($product,$request);

$ cartparams包含产品数量，自定义选项......等。 $ cartparams传入dataobject，然后将其传递给购物车addProduct方法，它对我有用。
