Hyperf中间件

*  Hyperf中的中间件还是比较类似与laravel，但是还是有些区别，Hyperf中可以使用注解的方式在对应的控制器方法进行添加

# 新建去全局中间件 #

> php ./bin/hyperf.php gen:middleware TestMiddleware

<?php
    
    declare(strict_types=1);
    
    namespace App\Middleware;
    
    use Hyperf\HttpServer\Contract\RequestInterface;
    use Psr\Container\ContainerInterface;
    use Psr\Http\Message\ResponseInterface;
    use Psr\Http\Server\MiddlewareInterface;
    use Psr\Http\Message\ServerRequestInterface;
    use Psr\Http\Server\RequestHandlerInterface;
    use Hyperf\HttpServer\Contract\ResponseInterface as HttpResponse;
    
    class TtMiddleware implements MiddlewareInterface
    { 
        /** * @var ContainerInterface */
        protected $container;
        /** * @var RequestInterface */
        protected $request;
        /** * @var HttpResponse */
        protected $response;
    
    
        public function __construct(ContainerInterface $container, RequestInterface $request, HttpResponse $response)
        { 
            $this->container = $container;
            $this->request = $request;
            $this->response = $response;
        }
    
    
        public function process(ServerRequestInterface $request, RequestHandlerInterface $handler): ResponseInterface
        { 
            $test = false;
            if ($test) { 
                return $handler->handle($request);
    
            }
    
            return $this->response->json([
                'code' => -1,
                'message' => '无法访问'
            ]);
        }
    }

*  在`config/autoload/middlewares.php`进行配置全局中间，过滤所有请求

return [
        'http' => [
            \App\Middleware\TestMiddleware::class
        ],
    ];

# 路由文件配置中间件 #

*  引用官方文档

<?php
    use App\Middleware\FooMiddleware;
    use Hyperf\HttpServer\Router\Router;
    
    // 每个路由定义方法都可接收一个 $options 参数
    Router::get('/', [\App\Controller\IndexController::class, 'index'], ['middleware' => [FooMiddleware::class]]);
    Router::post('/', [\App\Controller\IndexController::class, 'index'], ['middleware' => [FooMiddleware::class]]);
    Router::put('/', [\App\Controller\IndexController::class, 'index'], ['middleware' => [FooMiddleware::class]]);
    Router::patch('/', [\App\Controller\IndexController::class, 'index'], ['middleware' => [FooMiddleware::class]]);
    Router::delete('/', [\App\Controller\IndexController::class, 'index'], ['middleware' => [FooMiddleware::class]]);
    Router::head('/', [\App\Controller\IndexController::class, 'index'], ['middleware' => [FooMiddleware::class]]);
    Router::addRoute(['GET', 'POST', 'HEAD'], '/index', [\App\Controller\IndexController::class, 'index'], ['middleware' => [FooMiddleware::class]]);
    
    // 该 Group 下的所有路由都将应用配置的中间件
    Router::addGroup(
        '/v2', function () { 
            Router::get('/index', [\App\Controller\IndexController::class, 'index']);
        },
        ['middleware' => [FooMiddleware::class]]
    );

# 注解中间件 #

*  注解中间件可使用多中间件和单中间件，执行顺序为全局中间件=》类中间件=》方法中间件

<?php
    declare(strict_types=1);
    
    namespace App\Controller;
    
    use Hyperf\HttpServer\Annotation\AutoController;
    use Hyperf\HttpServer\Annotation\Middleware;
    use App\Middleware\TtMiddleware;
    use Hyperf\HttpServer\Annotation\Middlewares;
    
    /** * @AutoController() * @Middlewares({ * @Middleware(TtMiddleware::class) * }) */
    class TtController extends AbstractController
    { 
        /** * @Middleware(TtMiddleware::class) */
        public function index()
        { 
            return $this->response->json("index");
        }
    }
