在我的app/config/config.yml
中,我添加了monolog的控制台处理程序:
monolog:
handlers:
console:
type: console
因此,当我传递详细标记-vvv
时,命令会产生对monolog的调用的输出,例如:
./bin/console text:hello k0pernikus -vvv
[2016-06-01 13:19:27] event.DEBUG: Notified event "console.command" to listener "Symfony\Component\HttpKernel\EventListener\DebugHandlersListener::configure". {"uid":"c1e943a"}
[2016-06-01 13:19:27] event.DEBUG: Notified event "console.command" to listener "Symfony\Bridge\Monolog\Handler\ConsoleHandler::onCommand". {"uid":"c1e943a"}
Ipsum lorem dolorem
Hello k0pernikus!
Ipsum lorem dolorem
现在我想通过
grep第一行/bin/console text:hello k0pernikus -vvv | grep DebugHandlersListener::configure
但我也得到了第二个DEBUG:
[2016-06-01 13:21:17] event.DEBUG: Notified event "console.command" to listener "Symfony\Component\HttpKernel\EventListener\DebugHandlersListener::configure". {"uid":"9e84992"}
[2016-06-01 13:21:17] event.DEBUG: Notified event "console.command" to listener "Symfony\Bridge\Monolog\Handler\ConsoleHandler::onCommand". {"uid":"9e84992"}
我还注意到输出行为很奇怪,因为我也无法重定向它:
./bin/console text:hello k0pernikus -vvv > fnord
[2016-06-01 13:22:13] event.DEBUG: Notified event "console.command" to listener "Symfony\Component\HttpKernel\EventListener\DebugHandlersListener::configure". {"uid":"f21ef6f"}
[2016-06-01 13:22:13] event.DEBUG: Notified event "console.command" to listener "Symfony\Bridge\Monolog\Handler\ConsoleHandler::onCommand". {"uid":"f21ef6f"}
cat fnord
Ipsum lorem dolorem
Hello k0pernikus!
Ipsum lorem dolorem
这似乎是想要的行为,但我对如何使用详细程度输出感到有点困惑。我对所有线路都不感兴趣,就在其中一条线路上。
如何grep for one line?
我的命令:
<?php
namespace Kopernikus\ApiBundle\Command;
use Symfony\Component\Console\Command\Command;
use Symfony\Component\Console\Input\InputArgument;
use Symfony\Component\Console\Input\InputInterface;
use Symfony\Component\Console\Output\OutputInterface;
/**
* PlainTextHelloWorldCommand
**/
class PlainTextHelloWorldCommand extends Command
{
/**
*
*/
protected function configure()
{
$this
->setName('text:hello')
->addArgument('reciever', InputArgument::REQUIRED, 'Who do you want to greet?');
}
/**
* @param InputInterface $input
* @param OutputInterface $output
* @return int|null|void
*/
protected function execute(InputInterface $input, OutputInterface $output)
{
$reciever = $input->getArgument('reciever');
$output->writeln("Ipsum lorem dolorem");
$output->writeln("Hello {$reciever}!");
$output->writeln("Ipsum lorem dolorem");
}
}
答案 0 :(得分:2)
./bin/console text:hello k0pernikus -vvv 2>&1 >/dev/null | grep DebugHandlersListener::config
[2016-06-01 13:56:11] event.DEBUG: Notified event "console.command" to listener "Symfony\Component\HttpKernel\EventListener\DebugHandlersListener::configure". {"uid":"885c2f6"}
问题是日志信息没有写入标准输出,而是写入错误流。
