自定义Laravel (monolog)日志位置,并增加请求ID的实现

$app- configureMonologUsing(function($monolog) use ($app) {
 $monolog- pushHandler(
  (new MonologHandlerRotatingFileHandler(
   '/var/logs/app/laravel',
   $app- make('config')- get('app.log_max_files', 5)
  ))- setFormatter(new MonologFormatterLineFormatter(null, null, true, true))
 );
});
