1. 生成中间件和控制器
php bin/hyperf.php gen:middleware TestMiddleware
php bin/hyperf.php gen:controller TestController
2. 定义中间件
<?php
declare(strict_types=1);
namespace App\Middleware;
use Hyperf\HttpServer\Contract\RequestInterface;
use Hyperf\HttpServer\Contract\ResponseInterface as HttpResponse;
use Hyperf\Utils\Context;
use Psr\Container\ContainerInterface;
use Psr\Http\Message\ResponseInterface;
use Psr\Http\Server\MiddlewareInterface;
use Psr\Http\Message\ServerRequestInterface;
use Psr\Http\Server\RequestHandlerInterface;
class TestMiddleware 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
{
// 将新的请求对象设置到上下文中
$request = $request->withAttribute('name', 'danton');
Context::set(ServerRequestInterface::class, $request);
return $handler->handle($request);
}
}
```
### 3. 定义控制器
```php
<?php
declare(strict_types=1);
namespace App\Controller;
use Hyperf\HttpServer\Annotation\Middleware;
use Hyperf\HttpServer\Annotation\RequestMapping;
use App\Middleware\TestMiddleware;
use Hyperf\Utils\Context;
use Psr\Http\Message\ServerRequestInterface;
/**
* Class TestController
* @package App\Controller
* @\Hyperf\HttpServer\Annotation\Controller()
*/
class TestController extends Controller
{
/**
* @RequestMapping(path="/test", methods="get, post")
* @Middleware(TestMiddleware::class)
*/
public function test()
{
// 获取上下文中的所有属性，指定属性使用getAttribute('name')
return $this->request->getAttributes();
// 效果同上
return Context::get(ServerRequestInterface::class)->getAttributes();
}
}
4. 启动http服务
php bin/hyperf.php start
curl 127.0.0.1:9508/test // {"name":"danton"}
