How a add an appending / to TYPO3 v9 URLs?

问题:

When updating from TYPO3 8.7 to TYPO3 9.5 you might drop the realurl extension in favor for the new routing feature.

But you might notice, that realurl appended a / to all urls by default (when you are not using html suffix) The TYPO3 routing feature does not do that by default and there is currently no option in the core to enable this. Why is this a problem? In TYPO3 8.7 you got an URL like www.domain.tld/subpage/. In TYPO3 9.5 the same page be called with the url www.domain.tld/subpage. So even if this is the same page, for search crawlers, this is another URL. TYPO3 does a 307 redirect when calling the URL with an appending /, but you might want to use your old URL structure.

How can I teach TYPO3 to add an appending /?

回答1:

To always add an appending /, you can create yourself a route enhancer decorator and put it in your site package.

Create a file in your site package under Classes/Routing/Enhancer/ForceAppendingSlashDecorator.php with the content:

<?php
declare(strict_types=1);
namespace MyVendor\SitePackage\Routing\Enhancer;

use TYPO3\CMS\Core\Routing\Enhancer\AbstractEnhancer;
use TYPO3\CMS\Core\Routing\Enhancer\DecoratingEnhancerInterface;
use TYPO3\CMS\Core\Routing\RouteCollection;

class ForceAppendingSlashDecorator extends AbstractEnhancer implements DecoratingEnhancerInterface
{
    /**
     * {@inheritdoc}
     */
    public function getRoutePathRedecorationPattern(): string
    {
        return '\/$';
    }

    /**
     * {@inheritdoc}
     */
    public function decorateForMatching(RouteCollection $collection, string $routePath): void
    {
        foreach ($collection->all() as $route) {
            $route->setOption('_decoratedRoutePath', '/' . trim($routePath, '/'));
        }
    }

    /**
     * {@inheritdoc}
     */
    public function decorateForGeneration(RouteCollection $collection, array $parameters): void
    {
        foreach ($collection->all() as $routeName => $existingRoute) {
            $existingRoutePath = rtrim($existingRoute->getPath(), '/');
            $existingRoute->setPath($existingRoutePath . '/');
        }
    }
}

Please replace set the correct namespace matching your site package.

To register your route enhancer, add the line to your ext_localconf.php:

$GLOBALS['TYPO3_CONF_VARS']['SYS']['routing']['enhancers']['ForceAppendingSlash'] = \MyVendor\SitePackage\Routing\Enhancer\ForceAppendingSlashDecorator::class;

As a last step, put the following code into your site configuration yaml file:

routeEnhancers:
  PageTypeSuffix:
    type: ForceAppendingSlash

After this adjustments, TYPO3 will always add an appending / to your URLs so the new URLs will match the old ones created by realurl.

Additional to the answer from Tim Schreiner, i made a condition in the .htaccess file, which redirects urls whithout slashes to the url with trailing slash. Files should not be affected by this condition. Following condition did i add to the .htaccess file:

# EXTRA: Enforce trailing slash. Ignore trailing slash on file endings 
RewriteBase /
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_URI} !(.*)/$
RewriteCond %{REQUEST_FILENAME} !\.(gif|jpg|png|jpeg|css|js|xml|rss|txt)$ [NC]
RewriteCond %{REQUEST_URI} !\.(gif|jpg|png|jpeg|css|js|xml|rss|txt)$ [NC]
RewriteRule ^(.*[^/])$ /$1/ [L,R=301]

Tim, are you sure about getRoutePathRedecorationPattern()?

For me, it worked in two totally different TYPO3 (v9.5.3) instances in production, but both projects did not work in a ddev-container. There, the slugCandidates have always missed its last char.

Changing the pattern from "all except slash" to "exactly a slash" makes it work.

public function getRoutePathRedecorationPattern(): string
{
    return '\/$';
}

You can use the PageTypeEnhancer for mapping &type parameter in your site configuration (config.yaml file):

routeEnhancers:
  PageTypeSuffix:
    type: PageType
    default: '/'
    map:
      '/': 0
