Troubleshooting

php-http/discovery

If using a project/library that requires php-http/discovery, a list of 9 "well-known" implementations is forced.

Workaround to install custom implementations of your choice:

1. Create custom strategy - implement Http\Discovery\Strategy\DiscoveryStrategy:

<?php

declare(strict_types=1);

namespace Project\Factory\Http\Discovery;

use Http\Discovery\Strategy\DiscoveryStrategy;
use Psr\Http\Message\RequestFactoryInterface;
use Psr\Http\Message\StreamFactoryInterface;
// A RequestFactoryInterface implementation of your choice:
use WebServCo\Http\Factory\Message\Request\RequestFactory;
// A StreamFactoryInterface implementation of your choice: 
use WebServCo\Http\Factory\Message\Stream\StreamFactory;

final class Psr17DiscoveryStrategy implements DiscoveryStrategy
{
    /**
     * @inheritDoc
     * @param string $type
     * @return array<array<string, string>>
     */
    public static function getCandidates($type)
    {
        if ($type === RequestFactoryInterface::class) {
            return [
                [
                    'class' => RequestFactory::class,
                ],
            ];
        }

        if ($type === StreamFactoryInterface::class) {
            return [
                [
                    'class' => StreamFactory::class,
                ],
            ];
        }

        return [];
    }
}

1. Use custom strategy:

use Http\Discovery\ClassDiscovery;
use Project\Factory\Http\Discovery\Psr17DiscoveryStrategy;

// Before instantiating the class that uses `php-http/discovery`
ClassDiscovery::prependStrategy(Psr17DiscoveryStrategy::class);
