当我尝试在 Slim 4 的先前中间件中设置属性时遇到问题。

我在 app/middleware.php 中使用中间件
我使用 JwtAuthentication 中间件来检查令牌，我想将解码的令牌传递给下一个中间件：CheckTokenInDatabaseMiddleware。

我返回了带有解码令牌的 $request ：return $response->withAttribute("decoded", $arguments['decoded']);

在 CheckTokenInDatabaseMiddleware 中 $request->getAttribute('decoded') 返回 NULL

我有一个纤细的骨架并使用它：

应用程序/中间件.php

declare(strict_types=1);

use App\Application\Middleware\CheckTokenInDatabaseMiddleware;
use App\Application\Middleware\SessionMiddleware;
use Psr\Http\Message\ResponseInterface as Response;
use Psr\Http\Message\ServerRequestInterface as Request;
use Slim\App;
use Tuupola\Middleware\JwtAuthentication;

return function (App $app) {
    $app->add(SessionMiddleware::class);
    $app->add(new JwtAuthentication([
        "ignore" => ['/auth/signin', '/auth/signout'],
        'path' => ['/auth/me'],
        'secret' => getenv('JWT_SECRET'),
        "before" => function (Request $request, $arguments) {
            return $request->withAttribute("decoded", $arguments["decoded"]);
        }
    ]));
    $app->add(CheckTokenInDatabaseMiddleware::class);
};

应用程序/应用程序/中间件/CheckTokenInDatabaseMiddleware.php

declare(strict_types=1);

namespace App\Application\Middleware;

use App\Domain\User\UserRepository;
use Psr\Http\Message\ResponseInterface as Response;
use Psr\Http\Message\ServerRequestInterface as Request;
use Psr\Http\Server\MiddlewareInterface as Middleware;
use Psr\Http\Server\RequestHandlerInterface as RequestHandler;

class CheckTokenInDatabaseMiddleware implements Middleware
{
    protected $userRepository;

    /**
     * {@inheritdoc}
     */
    public function process(Request $request, RequestHandler $handler): Response
    {
        $token = $request->getAttribute('decoded');

        var_dump($token); // returns NULL
        die();

        return $handler->handle($request);
    }

    public function __construct(UserRepository $userRepository)
    {
        $this->userRepository = $userRepository;
    }
}

我找到了答案。
在苗条的中间件中，您必须记住它是 FILO。因此，如果要将属性从中间件 A 传递给中间件 B，则必须将它们以相反的顺序排列，即：

应用程序/中间件.php

...
return function (App $app) {
    $app->add(BMiddleware::class);
    $app->add(AMiddleware::class);
};
