在Lumen 5.2中配置日志旋转

Question

我试着在Lumen上配置日志旋转，但是我被卡住了。我知道如何用拉拉维尔来做这件事，但是(再一次)我和Lumen迷路了。

我试图在app/bootstrap.php中添加它，因为我在某个地方读到了它：

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

我可以看到这个错误：

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

我不明白这意味着什么，我应该怎么做。

有人成功地在流明5.2中旋转了日志吗？

Answer 1

忘记了返回对象，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)
    );
});

Answer 2

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者添加到Lumen bootstrap/app.php中：

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