NoTrailingSlashSeoUrl (Shopware 6 Plugin)

Allows SEO URLs for categories without a trailing slash.

Without this extension, category URLs that do not end with a trailing slash would_

• before 6.6.1.0 - lead to a 404 Not Found error page.
• since 6.6.1.0 - yield the same page as the URL with a trailing slash, which might be penalized by search engines as duplicate conent.

With this extension, those URLs will lead to the expected category page. The extension respects Shopware's SEO forwarding behavior setting, either a 301 redirect or a rel="canonical" HTTP header.

The problem is described in this issue: shopware/shopware#468

There is also a forum discussions about it (german): https://forum.shopware.com/t/seiten-nur-mit-am-ende-der-url-aufrufbar/65242

How to use it

Important

Always test new plugin versions in a dev environment before using it in a production/live shop.

1. Download the ZIP archive from the latest release.
2. Copy the ZIP archive into the custom/plugins directory of your Shopware 6 installation.
3. Unzip the ZIP archive.
4. There should now be a folder named BaristaNoTrailingSlashSeoUrl in the custom/plugins directory of your Shopware 6 installation.
5. Log in to the Admin UI of your shop and go to Extensions > MyExtensions.
6. Find the SEO category URLs without trailing slash extension (Deutsch: SEO Kategorie URLs ohne abschließenden Schrägstrich) in the list.
7. Install and activate it.

How it works

The Shopware\Core\Content\Seo\SeoResolver class resolves SEO URLs to native Shopware URLs. SeoResolver is called by Shopware\Storefront\Framework\Routing\RequestTransformer for each request. SeoResolver searches in the seo_url for an entry that matches the actual path (seo_path_info). That entry will contain the shopware native path (path_info). RequestTransformer then replaces the actual path of the request URL with the value of path_info. If SeoResolver does not find a matching entry, it just returns the actual path for path_info.

Luckily, SeoResolver is not called directly by RequestTransformer. Instead, an instance of AbstractSeoResolver, which SeoResolver extends, is injected as a service into RequestTransformer. That means we can use Symfonys service decoration pattern to adjust the behavior of SeoResolver to our needs. See this chapter in the Shopware 6 documentation for an explanation of how that is done.
