    Log::error($e->getMessage());
    
    // 发送电子邮件通知
    Mail::to('admin@example.com')->send(new ExceptionNotification($e));
    
    // 返回友好错误页面
    return response()->view('errors.500', [], 500);
}

In the resources/views/errors directory, we can create different view files to handle specific types of errors, such as 404 page does not exist, 500 server error, etc. This way, when the corresponding type of error occurs in the application, Laravel will automatically load the corresponding error view. We can provide detailed information about the error, along with appropriate solutions, in these view files.
