    },
    {
      "attribute_code": "product_id",
      "value": "iPhone7"
    }
  ]
}

在下面显示产品链接的部分中，我需要显示另一个参数Product id以及所有详细信息

 "product_links": [
    {
      /////////need product id here////////////
      "sku": "iPhone 7",
      "link_type": "related",
      "linked_product_sku": "Gold Leather cases",
      "linked_product_type": "simple",
      "position": 4,
      "extension_attributes": []
    },
    {

---

在上面的描述中，我需要sku前的产品id。有人能帮我解决这个问题吗？

您需要在

\Magento\Catalog\Model\ProductLink\Repository:：getList

foreach (array_keys($linkTypes) as $linkTypeName) {
        $collection = $this->entityCollectionProvider->getCollection($product, $linkTypeName);
        foreach ($collection as $item) {
            /** @var \Magento\Catalog\Api\Data\ProductLinkInterface $productLink */
            $productLink = $this->productLinkFactory->create();
            $productLink->setSku($product->getSku())
                ->setLinkType($linkTypeName)
                ->setLinkedProductSku($item['sku'])
                ->setLinkedProductType($item['type'])
                ->setPosition($item['position']);
            if (isset($item['custom_attributes'])) {
...
