Slim：如何将所有请求记录到框架

Question

我想将所有请求记录到我的 Slim Rest 服务器。 200 正常，404 错误等...

使用以下代码，我只能记录异常。我想记录所有传入的请求。

require 'Slim/Slim.php';

\Slim\Slim::registerAutoloader();

require 'Slim/Extras/Log/DateTimeFileWriter.php';

$app = new \Slim\Slim (
    array(
        'debug' => true,
        'log.enabled' => true,
        'log.level' => \Slim\Log::DEBUG,
        'log.writer' => new \Slim\Extras\Log\DateTimeFileWriter(array(
            'path' => '/tmp/slim',
            'name_format' => 'Y-m-d',
            'message_format' => '%label% - %date% - %message%'
        ))
    )
);

有了 slim v3，你 can't use hooks anymore.

这是我想出的解决方案：

添加一个新的中间件

可以将中间件视为应用于每个传入请求的函数。因此，它会拦截每个请求，允许我们记录所需的一切。

use \Psr\Http\Message\ServerRequestInterface as Request;
use \Psr\Http\Message\ResponseInterface as Response;

$app->add(function (Request $request, Response $response, callable $next) {
    $route = $request->getAttribute('route');
    $this->logger->info($request->getMethod() . ' ' . $route->getPattern(), [$route->getArguments()]);
    $response = $next($request, $response);
    $this->logger->info($response->getStatusCode() . ' ' . $response->getReasonPhrase(), [(string)$response->getBody()]);

    return $response;
});

记录器设置

当然，你需要像这样在容器中设置 Logger 依赖

$container = $app->getContainer();

// monolog
$container['logger'] = function ($c) {
    $settings = $c->get('settings')['logger'];
    $logger = new Monolog\Logger($settings['name']);
    $logger->pushProcessor(new Monolog\Processor\UidProcessor());
    $logger->pushHandler(new Monolog\Handler\StreamHandler($settings['path'], $settings['level']));
    return $logger;
};

使用记录器设置

return [
    'determineRouteBeforeAppMiddleware' => true, //VERY IMPORTANT for route logging
    'settings' => [
        // Monolog settings
        'logger' => [
            'name' => 'slim-app',
            'path' => __DIR__ . '/../logs/app.log',
            'level' => \Monolog\Logger::DEBUG,
        ]
    ]
]

输出

[2017-06-18 03:40:19] slim-app.INFO: GET /api/publication/{id:[0-9]+} [{"id":"0"}] {"uid":"6e64305"}
[2017-06-18 03:40:19] slim-app.INFO: 200 OK ["[]"] {"uid":"6e64305"}

希望这对某人有所帮助

看起来您想要基于您的问题的响应数据：

200 正常，404 错误等...

无论您需要请求还是响应信息，您都可以使用Slim Hooks 做您想做的事情。我现在无法提供完整的示例，但在未经测试的、无法理解的代码中，它可能看起来像：

// slim.after.dispatch would probably work just as well. Experiment
$app->hook('slim.after.router', function () use ($app) {
    $request = $app->request;
    $response = $app->response;

    $app->log->debug('Request path: ' . $request->getPathInfo());
    $app->log->debug('Response status: ' . $response->getStatus());
    // And so on ...
});
