这是一个用于集成中间件与 Phalcon 5 的包。中间件提供了一种方便的机制来检查和过滤进入您应用程序的 HTTP 请求。

安装

使用 composer 安装此包。

composer require nin/phalcon-middleware 

在 index.php 中注册一个提供者

$container = new \Phalcon\Di\FactoryDefault();
$container->register(new \Nin\Middleware\ServiceProvider());

或者 app/config/providers.php

return [
    \Nin\Middleware\ServiceProvider::class,
];   

使用方法

配置

创建配置文件 config/middleware.php

<?php

return [
    // The application's global HTTP middleware stack
    // These middleware are run during every request to your application.
    'middleware_global' => [
         \App\Middleware\TrimStrings::class
    ],
    // The application's route middleware groups.
    'middleware_groups' => [
        'web' => [
            \App\Middleware\StartSession::class
        ],
        'api' => [
            \App\Middleware\ApiMiddleware::class,
            \App\Middleware\AdminApiMiddleware::class
        ]
    ],
];

创建中间件类

<?php

namespace App\Middleware;

use Nin\Middleware\Middleware;

class TestMiddleware extends Middleware
{
    public function handle($request)
    {
        if ($request->get('token') !== 'valid-token') {
            throw new \Exception('Token invalid.');
        }
        return parent::handle($request);
    }
}

将中间件分配给路由

use Phalcon\Mvc\Router;

$router = new Router();
$router->addGet(
    '/invoices/edit/{id}',
    [
        'controller' => 'invoices',
        'action' => 'edit',
        'middleware' => ['web', 'auth'],
    ]
);

对于组

new \Phalcon\Mvc\Router\Group([
    'module' => 'backend',
    'middleware' => 'web',
]);

将中间件分配给控制器

class InvoicesController extends Controller
{
    public function initialize()
    {
        $this->middleware->attach('auth');
    }

    public function editAction()
    {
    // OR:  $this->middleware->attach('auth');
    }

}

中间件参数

$this->middleware->attach( ['web', 'auth:admin']);

class AuthMiddleware  extends \Nin\Middleware\Middleware
{
    public function handle($request)
    {
        $param = $this->getParam();
        if ($param !== 'admin') {
            throw new \Exception('Authenticate Fail.');
        }
        return parent::handle($request);
    }
}

重定向

重定向到路由

public function handle($request)
{
    if ($this->getParam() !== 'admin') {
        return $this->redirectToRoute('login');
    }
    return parent::handle($request);
}

重定向到 URL

public function handle($request)
{
    if ($this->getParam() !== 'admin') {
        return $this->redirectToUrl('/login');
    }
    return parent::handle($request);
}
