Design patterns: Strategy pattern

ApikeyStrategy.php

<?php

namespace Strategy\Auth;

use Strategy\AuthInterface;
use Bling\Controller\UserController;

class ApiKeyStrategy implements AuthInterface {
    public function authenticate(...$params): bool {
        $userController = new UserController();

        return $userController->getByApiKey($params['apikey']);
    }
}

AuthContext.php

<?php

namespace Strategy;

use Strategy\AuthInterface;

class AuthContext {
    private static $authStrategy;
    
    public static function setAuthStrategy(AuthInterface $authStrategy): void {
        self::$authStrategy = $authStrategy;
    }

    public static function authenticate(...$params): bool {
        return self::$authStrategy->authenticate($params);
    }
}

AuthInterface.php

<?php

namespace Strategy;

interface AuthInterface {
    public function authenticate(...$params): bool;
}

index.php

<?php

use Strategy\Auth\ApiKeyStrategy;
use Strategy\Auth\LoginStrategy;
use Strategy\Auth\OAuth2Strategy;

// Quando a requisição vier da interface
AuthContext::setAuthStrategy(new LoginStrategy());
AuthContext::authenticate([
    'login' => '',
    'pass' => ''
]);

// Quando a requisição vier da API utilizando API Key
AuthContext::setAuthStrategy(new ApiKeyStrategy());
AuthContext::authenticate([
    'apikey' => ''
]);

// Quando a requisição vier da API utilizando OAuth2
AuthContext::setAuthStrategy(new OAuth2Strategy());
AuthContext::authenticate([
    'accessToken' => ''
]);

LoginStrategy.php

<?php

namespace Strategy\Auth;

use Strategy\AuthInterface;
use Bling\Controller\UserController;

class LoginStrategy implements AuthInterface {
    public function authenticate(...$params): bool {
        $userController = new UserController();
        
        return $userController->getByLogin($params['login'], $params['pass']);
    }
}

OAuth2Strategy.php

<?php

namespace Strategy\Auth;

use Strategy\AuthInterface;
use Bling\Controller\UserController;

class OAuth2Strategy implements AuthInterface {
    public function authenticate(...$params): bool {
        $userController = new UserController();
