獲得來自Symfony的\分量\ HttpFoundation頭\響應

Question

出於調試目的，我想記錄從響應對象的所有頭，像這樣在filters.php：

App::after(function($request, $response) { 
    if(App::environment() !== 'dev') { return; } 

    error_log(print_r($response->getHeadersPleaaase())); 

$response通常是Illuminate\Http\JsonResponse，我無法找到任何明顯的獲取標題的方法。

Answer 1

集管是一個公共屬性：

error_log(print_r($response->headers)); 

Answer 2

ini_set("log_errors", 1); 
ini_set("error_log", __DIR__.'/../app/logs/prod.log');//ini_set("error_log", your path and file); 
error_log('BEGIN===========>'); 
error_log($request); 
error_log($response); 
error_log('<========END'); 

使用的例子（Symfony2的）

app.php

<?php 

use Symfony\Component\ClassLoader\ApcClassLoader; 
use Symfony\Component\HttpFoundation\Request; 

$loader = require_once __DIR__.'/../app/bootstrap.php.cache'; 

// Use APC for autoloading to improve performance. 
// Change 'sf2' to a unique prefix in order to prevent cache key conflicts 
// with other applications also using APC. 
/* 
$apcLoader = new ApcClassLoader('sf2', $loader); 
$loader->unregister(); 
$apcLoader->register(true); 
*/ 

require_once __DIR__.'/../app/AppKernel.php'; 
//require_once __DIR__.'/../app/AppCache.php'; 

$kernel = new AppKernel('prod', false); 
$kernel->loadClassCache(); 
//$kernel = new AppCache($kernel); 

// When using the HttpCache, you need to call the method in your front controller instead of relying on the configuration parameter 
//Request::enableHttpMethodParameterOverride(); 
$request = Request::createFromGlobals(); 
$response = $kernel->handle($request); 

ini_set("log_errors", 1); 
ini_set("error_log", __DIR__.'/../app/logs/prod.log'); 
error_log('BEGIN===========>'); 
error_log($request); 
error_log($response); 
error_log('<========END'); 

$response->send(); 
$kernel->terminate($request, $response);
