描述

为kNot框架提供的管道库。

特性

演示

示例 1：如何使用中间件和管道

use Psr\Http\Server\MiddlewareInterface;
use Psr\Http\Message\ServerRequestInterface;
use Psr\Http\Server\RequestHandlerInterface;
use knotlib\kernel\Request\PhpArrayRequest;
use knotlib\pipeline\pipeline;

class FirstMiddleware implements MiddlewareInterface
{
    public function process(ServerRequestInterface $request, RequestHandlerInterface $handler)
    {
        echo 'FirstMiddleware: 1' . PHP_EOL;
        $response = $handler->handle($request);
        echo 'FirstMiddleware: 2' . PHP_EOL;
        return $response;
    }
}
class SecondMiddleware implements MiddlewareInterface
{
    public function process(ServerRequestInterface $request, RequestHandlerInterface $handler)
    {
        echo 'SecondMiddleware: 1' . PHP_EOL;
        $response = $handler->handle($request);
        echo 'SecondMiddleware: 2' . PHP_EOL;
        return $response;
    }
}
class ThirdMiddleware implements MiddlewareInterface
{
    public function process(ServerRequestInterface $request, RequestHandlerInterface $handler)
    {
        echo 'ThirdMiddleware: 1' . PHP_EOL;
        $response = $handler->handle($request);
        echo 'ThirdMiddleware: 2' . PHP_EOL;
        return $response;
    }
}

$pipeline = new pipeline();
$pipeline->push(new FirstMiddleware());
$pipeline->push(new SecondMiddleware());
$pipeline->push(new ThirdMiddleware());

$pipeline->run(new PhpArrayRequest);

输出

ThirdMiddleware: 1
SecondMiddleware: 1
FirstMiddleware: 1
FirstMiddleware: 2
SecondMiddleware: 2
ThirdMiddleware: 2
