在注释限制上重写异常处理程序。Laravel 8

<?php

namespace App\Exceptions;

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

class Handler extends ExceptionHandler
{
    /**
     * Render an exception into an HTTP response.
     *
     * @param  \Illuminate\Http\Request  $request
     * @param  \Exception  $exception
     * @return \Illuminate\Http\Response
     */
    public function render($request, Exception $exception)
    {
        if ($exception instanceof \Illuminate\Database\Eloquent\ModelNotFoundException) {
            // 处理模型未找到异常
            return response()->view('errors.model_not_found', [], 404);
        }

        if ($exception instanceof \Illuminate\Auth\Access\AuthorizationException) {
            // 处理授权异常
            return response()->view('errors.unauthorized', [], 403);
        }

        // 其他异常情况的处理

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