php - 如何通过中间件 Zend Framework 3 向控制器传递请求

Question

我正在使用 ZendFramework 3 组件开发 REST API。我决定使用中间件验证（验证）每个请求，如果请求有效，则传递给普通控制器操作以检索资源并发送回响应。

1. 这个概念是否正确？使用中间件包装控制器？

2. 如何使用以下代码和配置将请求传递给控制器​​？中间件

//file: myapp/module/Auth/src/Middleware/Authorize.php

namespace Auth\Middleware;

use Interop\Http\ServerMiddleware\DelegateInterface;
use Interop\Http\ServerMiddleware\MiddlewareInterface;
use Psr\Http\Message\ServerRequestInterface;
use Zend\Json\Json;
use Zend\Http\Response;
use Zend\Diactoros\Response\JsonResponse;
use Zend\Diactoros\Response\RedirectResponse;

class Authorize
{
    public function __invoke($request, $response)
    {
        // Validate $request code goes here ...

        $response->getBody()->write('Hello World!');
        return $response;
    }
}

路由器配置

//file: myapp/module/Auth/config/module.config.php
namespace Auth;

use Zend\Router\Http\Segment;
use Zend\ServiceManager\Factory\InvokableFactory;
use Doctrine\ORM\Mapping\Driver\AnnotationDriver;

return [
    'controllers' => [
        'factories' => [
            Controller\AuthController::class =>Controller\Factory\AuthControllerFactory::class,
        ],

    ],

    'service_manager' => [
        'factories' => [

Answer 1

因此，查看您的代码，让我印象深刻的是以下配置：

'defaults' => [
    'middleware' => [
        Middleware\Authorize::class,
        Controller\UserController::class,
    ],
    'controller' => Controller\UserController::class,
    'action'     => 'index',
],

您只能使用其中一个选项，不能同时使用两者，这是因为在 ZF3 中，中间件是从事件侦听器分派的，因此禁用了传统分派循环的其余部分。

因此，您可以同时删除控制器和操作行。

对于其余部分，这个概念是正确的，您绝对可以通过这种方式添加身份验证。如果您刚刚开始您的项目，我建议您使用 Zend Expressive。对您而言，不同之处在于您可以在任何其他中间件之前应用身份验证操作，而在 ZF3 中，您必须手动将其添加到每个路由。
