Question

我有行动：

public function getQuestions2Action()
{
    MY_CONSTANT;
}

应用程序/配置/ config_prod.yml

imports:
    - { resource: config.yml }

monolog:
    handlers:
        main:
            type:   stream
            path:   "%kernel.logs_dir%/%kernel.environment%.log"
            level: debug
            channels: "!event"

在/var/log/nginx/error.log中，我看到了：

2016/01/21 14:39:48 [error] 31596#0: *313 FastCGI sent in stderr: "PHP message: PHP Notice:  Use of undefined constant MY_CONSTANT - assumed 'MY_CONSTANT' in /var/www/datravel-client-api/src/Datravel/ClientApiBundle/Controller/RestController.php on line 289

但是app / logs / prod.log是空的

$ ls -la app/logs/
total 8
drwxrwxrwx 2 lebnik lebnik 4096 дек.  18 14:02 .
drwxrwxr-x 6 lebnik lebnik 4096 янв.  21 12:59 ..

-rwxrwxrwx 1 lebnik lebnik    0 дек.  18 14:02 prod.log

Prod缓存被清除。我期待关于未定义常量的记录通知。

Answer 1

与应用程序在＆＃34;调试模式＆＃34;中运行的dev环境不同。（这意味着symfony本身将error_reporting设置为E_ALL并且所有错误都转换为异常并记录），在prod环境error_reporting中是您已在php.ini和~~中设置了php错误，symfony~~ 不会处理。然而，PHP会将它们记录在error_log中指定的文件中，通常是/var/log/httpd/error_log或/var/log/apache2/error.log。

如果你想在生产中处理php错误以通过monolog记录它们，你可以注册Symfony\Component\HttpKernel\EventListener\DebugHandlersListener监听器。在您的服务中：

 debug.debug_handlers_listener:
     class: Symfony\Component\HttpKernel\EventListener\DebugHandlersListener
     arguments: [~, "@logger", 24575, ~, false]
     tags:
         -  { name: kernel.event_subscriber}

24575是E_ALL ^ E_DEPRECATED的输出。

我认为，既然两个环境中都有debug.debug_handlers_listener already exists，你应该像这样创建一个编译器传递：

namespace TestBundle\DependencyInjection\Compiler; use Symfony\Component\DependencyInjection\Compiler\CompilerPassInterface; use Symfony\Component\DependencyInjection\ContainerBuilder; class DebugHandlersCompilerPass implements CompilerPassInterface { public function process(ContainerBuilder $container) { if (!$container->getParameter('kernel.debug')) { $definition = $container->findDefinition('debug.debug_handlers_listener'); // by default is E_COMPILE_ERROR | E_PARSE | E_ERROR | E_CORE_ERROR $definition->replaceArgument(2, E_ALL ^ E_DEPRECATED); $definition->replaceArgument(4, false); } } }

然后像这样注册：

namespace TestBundle; use Symfony\Component\HttpKernel\Bundle\Bundle; use Symfony\Component\DependencyInjection\ContainerBuilder; use TestBundle\DependencyInjection\Compiler\DebugHandlersCompilerPass; class TestBundle extends Bundle { public function build(ContainerBuilder $container) { parent::build($container); // add this $container->addCompilerPass(new DebugHandlersCompilerPass()); } }

您现在需要做的就是将action_level: error文件中monolog的{{1}}更改为config_prod.yml。

Answer 2

您在/var/log/nginx/error.log中收到错误，说明未定义MY_CONSTANT。我不知道你的代码在哪里定义它（可能在超类或你包含的其他类中？），但我认为除了“你没有定义它”之外你不能获得任何信息，除非PHP解析器找不到它一个合适的地方。也许你可以搜索你的项目并找到你在哪里定义这个'MY_CONSTANT'的形式 const MY_CONSTANT = xxx

为什么symfony 2.7没有记录我的控制器的通知
