我需要所有输入和所有输出。我的，pipeline.php

$app->pipe(\Zend\Stratigility\Middleware\ErrorHandler::class);
$app->pipe(\Zend\Expressive\Helper\ServerUrlMiddleware::class);
$app->pipe(\App\Middleware\LogRequestsMiddleware::class);
$app->pipeRoutingMiddleware();
$app->pipe(\Zend\Expressive\Middleware\ImplicitHeadMiddleware::class);
$app->pipe(\Zend\Expressive\Middleware\ImplicitOptionsMiddleware::class);
$app->pipe(\Zend\Expressive\Helper\UrlHelperMiddleware::class);
$app->pipeDispatchMiddleware();
$app->pipe(\App\Middleware\LogResponseMiddleware::class);
$app->pipe(\Zend\Expressive\Middleware\NotFoundHandler::class);

LogResponseMiddleware 不执行。如果错误它也需要。

您可以很容易地记录请求和响应，只需创建一个中间件：

<?php
namespace Acme\Middleware;

use Psr\Log\LoggerInterface;
use Interop\Http\ServerMiddleware\DelegateInterface;
use Interop\Http\ServerMiddleware\MiddlewareInterface;
use Psr\Http\Message\ResponseInterface;
use Psr\Http\Message\ServerRequestInterface;

class LoggingMiddleware implements MiddlewareInterface
{
    /**
    * @var Psr\Log\LoggerInterface $logger
    */
    private $logger;

    public function __construct(LoggerInterface $logger)
    {
        $this->logger = $logger;
    }

    public function process(ServerRequestInterface $request, DelegateInterface $delegate) {
        // log the request
        $this->logger->log(Logger::INFO, 'Request', []);

        $response = $delegate->process($request);

        // log the response
        $this->logger->log(Logger::INFO, 'Response', []);

        return $response;
    }
}

在您的工厂中，您可以使用任何 PSR 记录器，例如 monolog：

<?php
namespace Acme\Middleware;

use Interop\Container\ContainerInterface;
use Psr\Log\LoggerInterface;

class LoggingMiddlewareFactory
{
    public function __invoke(ContainerInterface $container)
    {
        $logger = $container->get(LoggerInterface::class);

        return new LoggingMiddleware($logger);
    }
}

最后，必须在 ServerUrlMiddleware 之后将日志中间件添加到管道中：

<?php
// config/pipeline.php
$app->pipe(ErrorHandler::class);
$app->pipe(ServerUrlMiddleware::class);

$app->pipe(LoggingMiddleware::class);

而已。

正确的顺序：

$app->pipe(\App\Middleware\LogResponseMiddleware::class);
$app->pipe(\Zend\Stratigility\Middleware\ErrorHandler::class);
$app->pipe(\Zend\Expressive\Helper\ServerUrlMiddleware::class);
$app->pipeRoutingMiddleware();
$app->pipe(\Zend\Expressive\Middleware\ImplicitHeadMiddleware::class);
$app->pipe(\Zend\Expressive\Middleware\ImplicitOptionsMiddleware::class);
$app->pipe(\Zend\Expressive\Helper\UrlHelperMiddleware::class);
$app->pipeDispatchMiddleware();
$app->pipe(\App\Middleware\LogRequestsMiddleware::class);
$app->pipe(\Zend\Expressive\Middleware\NotFoundHandler::class);
