如何在laravel 8中注册自定义异常处理程序

// app/Exceptions/Handler.php
namespace App\Exceptions;

use Exception;
use Illuminate\Foundation\Exceptions\Handler as ExceptionHandler;
use Throwable;
use Log;

class Handler extends ExceptionHandler
{
    public function report(Throwable $exception)
    {
        if ($this->isThrowable($exception)) {
            Log::error('Uncaught Exception: ', ['exception' => $exception]);
        }

        parent::report($exception);
    }

    public function render($request, Throwable $exception)
    {
        if ($exception instanceof CustomException) {
            return response()->json([
                'error' => 'Custom Error',
                'message' => $exception->getMessage(),
            ], 400);
        }

        return parent::render($request, $exception);
    }
}

// app/Exceptions/CustomException.php
namespace App\Exceptions;

use Exception;

class CustomException extends Exception
{
    // ...
}
