Magento 2 URL 重写问题：URL 指定商店的密钥已存在

Question

我在 Magento 2.2.5 上以编程方式保存产品时遇到此问题

在任何模块中，如果我在多个产品的循环内执行 $product->save(); 或 $this->productRepository->save($product);。我得到：

PDOException：SQLSTATE[23000]：违反完整性约束：1062 /home/dev3/www/vendor/magento/zendframework1/library/Zend/Db/Statement/Pdo 中键 'URL_REWRITE_REQUEST_PATH_STORE_ID' 的重复条目 'the-lipstick.html-1'。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，任何建议的修复，包括修改核心文件的修复 (DBStorage.php) 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

请为 M 2.2.5

建议 solution/fix

Answer 1

在迁移并深入研究问题一周后，唯一对我有用的是 https://www.safemage.com/url-optimization-after-migration-magento-2.html

我必须降级到 2.2.7 才能使用它。它说它可以在 2.3 上运行，但实际上没有。

Answer 2

在互联网上搜索了几天后，我找不到确切的解决方案。然后我发现如果我们更改类别的 URLKEY 它不会显示此错误所以我这样做了。

$category->setPath($parentCategory->getPath())
            ->setParentId($parentId)
            ->setName('test1')
            ->setIsActive(true)
            ->setUrlKey(rand(1,1000000000));

        $category->save();

我使用随机函数在数据库中添加类别，随机不使用 ->setUrlKey(rand(1,1000000000));您可以在其中添加任何内容，例如带有一些随机编号的重复类别名称等。如果它可以帮助您提供 UP，错误就会消失。谢谢

我的修复：在 di.xml -

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

在 ProductFixUrl 中写入这两个函数：

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 = [];

                $urlFound = parent::doFindOneByData(
                    [
                        UrlRewriteData::REQUEST_PATH => $url->getRequestPath(),

                    ]
                );
                if (isset($urlFound[UrlRewriteData::URL_REWRITE_ID])) {
                    $urlConflicted[$urlFound[UrlRewriteData::URL_REWRITE_ID]] = $url->toArray();
                }
            }
            if ($urlConflicted) {
