Php 为什么symfony 2.7不记录控制器的通知

我有以下行动：

public function getQuestions2Action()
{
    MY_CONSTANT;
}

app/config/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：

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/

Prod缓存已清除。我期待关于未定义常量的日志记录通知

您在/var/log/nginx/error.log中得到错误，表示未定义MY_常量。 我不知道您在代码中的何处定义了它（可能是在超类或您包含的其他类中？），但我认为您无法获得除“您尚未定义它”之外的任何信息，除非PHP解析器无法在适当的位置找到它。 也许你可以搜索你的项目，找到你在哪里定义这个“MY_常量”，格式如下

---

const MY_CONSTANT=xxx

与应用程序在“调试模式”下运行的

dev

环境不同（这意味着

error_reporting

由symfony自身设置为

E_ALL

，所有错误都转换为异常并记录），在

prod

环境中

错误报告

是您在

php.ini

中设置的内容，php错误不由symfony处理。但是，PHP将它们记录在中指定的文件中，通常是

/var/log/httpd/error\u log

或

/var/log/apache2/error.log

如果您想在生产中处理php错误，并通过monolog记录这些错误，可以注册

Symfony\Component\HttpKernel\EventListener\DebugHandlersListener

listener。为您服务：

 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

更新 我认为，由于这两种环境中的

debug.debug\u handlers\u listener

，您应该创建如下编译器过程：

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);
        }
    }
}

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());
    }
}

然后像这样注册它：

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);
        }
    }
}

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

config\u prod.yml

文件中

monolog

的

action\u level:error

更改为

action\u level:warning

从明显的开始-您清除了产品缓存了吗？您希望在日志中看到什么-您正在记录自定义通知吗？1。prod缓存已清除2。是的，请输入您试图记录的通知的代码-即从控制器复制和粘贴。没问题，一切就绪。我看到prod.log的所有者是“lebnik lebnik”。你试过检查权限是否有问题吗？我说不出来，我已经搜索过了，但什么也没找到。我甚至不认为在生产中这样做是个好主意。。只需查看您的

错误日志

文件即可。
