内联堆栈中间件。

启用将可调用对象用作堆栈中间件的使用。

示例

以下是一个虚构的示例，说明如何使用可调用对象轻松地将silex应用程序作为堆栈中间件使用。

use Symfony\Component\HttpFoundation\Request;
use Symfony\Component\HttpFoundation\Response;
use Symfony\Component\HttpKernel\HttpKernelInterface;

$app = new Silex\Application();

$app->get('/', function (Request $request) {
    if ('success' === $request->attributes->get('callable_middleware')) {
        return new Response('SUCCESS');
    }

    return new Response('FAILED', 500);
});

$inlineMiddleware = function(
    HttpKernelInterface $app,
    Request $request,
    $type = HttpKernelInterface::MASTER_REQUEST,
    $catch = true
) {
    $request->attributes->set('callable_middleware', 'success');

    $response = $app->handle($request, $type, $catch);
    $response->setContent('['.$response->getContent().']');

    return $response;
};

$stack = (new Stack\Builder())
    ->push('Stack\Inline', $inlineMiddleware);

$app = $stack->resolve($app);

用法

可调用方法的签名类似于 HttpKernelInterface::handle，但需要一个 HttpKernelInterface 实例作为其第一个参数。一个简单的中继内联中间件可能看起来像这样

$app = new Stack\Inline($app, function(
    HttpKernelInterface $app,
    Request $request,
    $type = HttpKernelInterface::MASTER_REQUEST,
    $catch = true
) {
    return $app->handle($request, $type, $catch);
});
