Laravel5.7 log的custom驱动写入报错

Question

我的目的是希望日志按照日期+小时+等级来分割
比如2019-04-10/11/info.log, 2019-04-10/11/error.log ...

报错

laravel.EMERGENCY: Unable to create configured logger. Using emergency logger. {"exception":"[object] (Illuminate\\Contracts\\Container\\BindingResolutionException(code: 0): Unresolvable dependency resolving [Parameter #0 [ <required> $name ]] in class Monolog\\Logger at D:\\phpStudy\\PHPTutorial\\WWW\\wdt_crm\\wdt_platform\\branch\\vendor\\laravel\\framework\\src\\Illuminate\\Container\\Container.php:960)

找不到错在哪里，求大神相助

logging.php 如下

'stack' => [
    'driver' => 'stack',
    'channels' => ['sliceLevels'],
],

....

'sliceLevels' => [
    'driver' => 'custom',
    'via' =>  App\Logging\Custom\LoggingByLevelLogger::class,
    'path' => storage_path('logs/level.log'),
    'level' => 'debug',
    'days' => 7,
],

新的logger类

namespace App\Logging\Custom;

use Monolog\Logger;
use App\Logging\Handler\LoggingByLevelHandler;

class LoggingByLevelLogger extends Logger
{
    // 当前记录日志的等级
    protected $level = 'info';

    public function __invoke(array $config)
    {
        // file_put_contents(storage_path('logs/test.txt'), print_r($config));

        $logger = new static('local');

        $logger->pushHandler(new LoggingByLevelHandler(
            $config['path'],
            $this->level,
            $config['days'],
            $config['level']
        ));

        return $logger;
    }

    /**
     * set record level
     *
     * @param int $level
     * @return void
     */
    public function setRecordLevel($level)
    {
        $this->level = strtolower(self::getLevelName($level));
    }

    /**
     * Adds a log record at the INFO level.
     *
     * This method allows for compatibility with common interfaces.
     *
     * @param  string $message The log message
     * @param  array  $context The log context
     * @return bool   Whether the record has been processed
     */
    public function info($message, array $context = array())
    {
        $this->setRecordLevel(static::INFO);

        return $this->addRecord(static::INFO, $message, $context);
    }

   ...
}

LoggingByLevelHandler类是对daily默认的handler进行了修改

已解决。由于门面只对应Monolog，所以找不到新写的Logger。所以采取的解决方案是使用monolog，自己重新写一个handler
