Tips

Client Settings

You can use any settings that your client supports, for example, a Guzzle Proxy:

<?php

declare(strict_types=1);

use GuzzleHttp\Client;
use GuzzleHttp\Psr7\HttpFactory;
use Illuminate\Http\Request;
use Ilzrv\LaravelSteamAuth\SteamAuthenticator;

public function __invoke(
    Request $request,
    HttpFactory $httpFactory,
): RedirectResponse {
    $client = new Client([
        'proxy' => 'socks5://user:password@192.168.1.1:1080',
    ]);

    $steamAuthenticator = new SteamAuthenticator(
        new Uri($request->getUri()),
        $client,
        $httpFactory,
    );
    
    // Continuation of your code...
}

Proxy Domain

If you want to make a proxy domain. Update redirect_url inside steam-auth.php to your absolute address like https://auth.test/login. You can use different domains for the local environment and for production like this:

<?php

declare(strict_types=1);

return [
    'redirect_url' => env('APP_ENV', 'production') == 'production'
        ? 'https://auth.test/login'
        : null,
];

In the NGINX settings for proxy domain, you can specify the following:

server {
    listen 443 ssl http2;
    server_name auth.test;
    return 301 https://general.test$uri$is_args$args;
}

Basic example

In routes/web.php:

Route::get('login', \App\Http\Controllers\Auth\SteamAuthController::class);

Create a controller SteamAuthController.php:

<?php

declare(strict_types=1);

namespace App\Http\Controllers\Auth;

use App\Models\User;
use GuzzleHttp\Client;
use GuzzleHttp\Psr7\HttpFactory;
use GuzzleHttp\Psr7\Uri;
use Illuminate\Auth\AuthManager;
use Illuminate\Http\RedirectResponse;
use Illuminate\Http\Request;
use Illuminate\Routing\Redirector;
use Ilzrv\LaravelSteamAuth\Exceptions\Authentication\SteamResponseNotValidAuthenticationException;
use Ilzrv\LaravelSteamAuth\Exceptions\Validation\ValidationException;
use Ilzrv\LaravelSteamAuth\SteamAuthenticator;
use Ilzrv\LaravelSteamAuth\SteamUserDto;

final class SteamAuthController
{
    public function __invoke(
        Request $request,
        Redirector $redirector,
        Client $client,
        HttpFactory $httpFactory,
        AuthManager $authManager,
    ): RedirectResponse {
        $steamAuthenticator = new SteamAuthenticator(
            new Uri($request->getUri()),
            $client,
            $httpFactory,
        );

        try {
            $steamAuthenticator->auth();
        } catch (ValidationException|SteamResponseNotValidAuthenticationException) {
            return $redirector->to(
                $steamAuthenticator->buildAuthUrl()
            );
        }

        $steamUser = $steamAuthenticator->getSteamUser();

        $authManager->login(
            $this->firstOrCreate($steamUser),
            true
        );

        return $redirector->to('/');
    }

    private function firstOrCreate(SteamUserDto $steamUser): User
    {
        return User::firstOrCreate([
            'steam_id' => $steamUser->getSteamId(),
        ], [
            'name' => $steamUser->getPersonaName(),
            'avatar' => $steamUser->getAvatarFull(),
            'player_level' => $steamUser->getPlayerLevel(),
            // ...and other what you need
        ]);
    }
}
