简而言之，我只想在结账时将目录价格规则应用于产品。我知道 Magento 1 的一些来源提供了很多解决方案，一个例子是这个博客https://jutesenthil.wordpress.com/2015/09/28/get-catalog-rule-by-product-id-in- magento/但试图在 Magento 2 中获得相同的结果似乎不起作用。我的代码片段如下。

/**
 * @param $productId
 * @param $customerGroupId
 * @return mixed
 */
public function getCatalogPriceRuleFromProduct($productId, $customerGroupId)
{
    /**
     * @var \Magento\Catalog\Model\ProductFactory
     */
    $product = $this->_objectManager->create('\Magento\Catalog\Model\ProductFactory')->create()->load($productId);

    $storeId = $product->getStoreId();

    $store = $this->_store_manager->getStore($storeId);

    $websiteId = $store->getWebsiteId();

    /**
     * @var \Magento\Framework\Stdlib\DateTime\DateTime
     */
    $date = $this->_objectManager->create('\Magento\Framework\Stdlib\DateTime\DateTime');
    $dateTs = $date->gmtDate();

    /**
     * @var \Magento\CatalogRule\Model\Rule
     */
    $resource = $this->_objectManager->create('\Magento\CatalogRule\Model\Rule');
    // $resource = $this->_objectManager->create('\Magento\CatalogRule\Model\RuleFactory');

    $rules = $resource->getRulesFromProduct($dateTs, $websiteId, $customerGroupId, $productId);
    /*$rules = $resource->getCollection()
        ->addFieldToFilter('from_time', $dateTs)
        ->addFieldToFilter('to_time', $dateTs)
        ->addFieldToFilter('product_id', …
