Question

我试图在Lumen上配置日志轮换但是我被卡住了。我知道如何用Laravel做到这一点，但是（再一次）我迷失了Lumen。

我尝试在app/bootstrap.php中添加它，因为我在某处读到了它：

$app->configureMonologUsing(function(Monolog\Logger $monolog) use ($app) {
    $monolog->pushHandler(
        new \Monolog\Handler\RotatingFileHandler($app->storagePath().'/logs/lumen.log', 5)
    );
});

我可以查看此错误：

Fatal error:  Uncaught Error: Call to a member function error() on null in /x/vendor/laravel/lumen-framework/src/Exceptions/Handler.php:36
Stack trace:
#0 /x/app/Exceptions/Handler.php(36): Laravel\Lumen\Exceptions\Handler->report(Object(Symfony\Component\Debug\Exception\FatalThrowableError))
#1 /x/vendor/laravel/lumen-framework/src/Concerns/RegistersExceptionHandlers.php(123): App\Exceptions\Handler->report(Object(Symfony\Component\Debug\Exception\FatalThrowableError))
#2 /x/vendor/laravel/lumen-framework/src/Concerns/RegistersExceptionHandlers.php(51): Laravel\Lumen\Application->handleUncaughtException(Object(Symfony\Component\Debug\Exception\FatalThrowableError))
#3 [internal function]: Laravel\Lumen\Application->Laravel\Lumen\Concerns\{closure}(Object(Error))
#4 {main}
  thrown in /x/vendor/laravel/lumen-framework/src/Exceptions/Handler.php on line 36

我不明白这是什么意思，我应该做些什么。

是否有人成功旋转了内存5.2中的日志？

另一个想法：

<?php

namespace App\Providers;

use Illuminate\Support\ServiceProvider;
use Monolog\Formatter\LineFormatter;
use Monolog\Handler\RotatingFileHandler;

class LogServiceProvider extends ServiceProvider
{
    /**
     * Configure logging on boot.
     *
     * @return void
     */
    public function boot()
    {
        $maxFiles = 7;

        $handlers[] = (new RotatingFileHandler(storage_path('logs/lumen.log'), $maxFiles))
            ->setFormatter(new LineFormatter(null, null, true, true));

        $this->app['log']->setHandlers($handlers);
    }

    /**
     * Register the log service.
     *
     * @return void
     */
    public function register()
    {
        // Log binding already registered in vendor/laravel/lumen-framework/src/Application.php.
    }
}

然后不要忘记将服务提供程序添加到Lumen bootstrap / app.php：

$app->register(\App\Providers\LogServiceProvider::class);

你忘记返回对象，它应该是：

$app->configureMonologUsing(function(Monolog\Logger $monolog) use ($app) {
    return $monolog->pushHandler(
        new \Monolog\Handler\RotatingFileHandler($app->storagePath().'/logs/lumen.log', 5)
    );
});

在Lumen 5.2中配置日志旋转
