php - Magento 2 URL 重写问题 : URL key already exists for specified store

Question

我在 Magento 2.2.5 上以编程方式保存产品时遇到了这个问题

在任何模块中，如果我在循环中执行 $product->save(); 或 $this->productRepository->save($product);多个产品。我得到:

PDOException:SQLSTATE[23000]:违反完整性约束:1062/home/dev3/www/vendor/magento/zendframework1/library/中键“URL_REWRITE_REQUEST_PATH_STORE_ID”的重复条目“the-lipstick.html-1” Zend/Db/Statement/Pdo.php:228

该错误类似于此处描述的错误:https://www.human-element.com/url-key-specified-store-already-exists-magento-2/

产品在管理区域登录后保存良好。

到目前为止，包括修改核心文件 (DBStorage.php) 在内的任何修复建议都不适用于 2.2.5。

到目前为止我尝试了什么:1. 从 https://www.human-element.com/url-key-specified-store-already-exists-magento-2/ 修复2. 从 https://magento.stackexchange.com/questions/210359/magento-2-product-url-rewrite-issue 修复

请建议 M 2.2.5 的解决方案/修复

我的修复:在 di.xml -

<preference for="Magento\UrlRewrite\Model\Storage\DbStorage" type="MyCompany\FixUrls\Model\ProductUrlFix" />

在 ProductFixUrl 中编写这两个函数:

protected function doReplace(array $urls){

    $this->deleteOld($urls);
        $data = [];
        $storeId_requestPaths = [];

        foreach ($urls as $url) {
            $storeId = $url->getStoreId();
            $requestPath = $url->getRequestPath();
            // Skip if is exist in the database
            $sql = "SELECT * FROM url_rewrite where store_id = $storeId and request_path = '$requestPath'";
            $exists = $this->connection->fetchOne($sql);

            if ($exists) {
                continue;
            }

            $storeId_requestPaths[] = $storeId . '-' . $requestPath;
            $data[] = $url->toArray();
        }
        try {

            $n = count($storeId_requestPaths);
            for ($i = 0; $i < $n - 1; $i++) {
                for ($j = $i + 1; $j < $n; $j++) {
                    if ($storeId_requestPaths[$i] == $storeId_requestPaths[$j]) {
                        unset($data[$j]);
                    }
                }
            }
            parent::insertMultiple($data);

        } catch (\Magento\Framework\Exception\AlreadyExistsException $e) {
            /** @var \Magento\UrlRewrite\Service\V1\Data\UrlRewrite[] $urlConflicted */
            $urlConflicted = [];
            foreach ($urls as $url) {
                $urlFound = parent::doFindOneByData(
                    [
                        UrlRewriteData::REQUEST_PATH => $url->getRequestPath(),
                        UrlRewriteData::STORE_ID => $url->getStoreId(),
                    ]
                );
                if (isset($urlFound[UrlRewriteData::URL_REWRITE_ID])) {
                    $urlConflicted[$urlFound[UrlRewriteData::URL_REWRITE_ID]] = $url->toArray();
                }
            }
            if ($urlConflicted) {
                throw new \Magento\UrlRewrite\Model\Exception\UrlAlreadyExistsException(
                    __('URL key for specified store already exists.'),
                    $e,

            } else {
                throw $e->getPrevious() ?: $e;
            }
        }

        return $urls;
    }

    /**

        // prevent query locking in a case when nothing to delete
        $checkOldUrlsSelect = clone $oldUrlsSelect;

        $checkOldUrlsSelect->columns('count(*)');
