我想为下图添加自定义错误页面。此页面必须显示错误。我怎样才能做到这一点？我正在使用下面给出的代码。在这段代码中，我有一个 try 部分和一个 catch 部分。此代码由 2checkout 提供。我试图从 catch 部分返回视图，但这没有用。如图所示，同样的错误即将到来。它的解决方案是什么？

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;

use App\Http\Requests;
use App\Http\Controllers\Controller;
use App\TwoCheckoutAccount;
use File;
//use App\Twocheckout\lib\Twocheckout as Twocheckout;
use Twocheckout;
use Twocheckout_Charge;
use App\Price;
use App\Payment;

class PaymentsController extends Controller
{


    /**
     * Display a listing of the resource.
     *
     * @return \Illuminate\Http\Response
     */
    public function index($type, $id)
    {
        $twoCheckOut = TwoCheckoutAccount::find(1);
        $price = Price::where('priceable', '=', $type)->firstOrFail();
        return view('payment')->with('twoCheckOut',$twoCheckOut)->with(['type'=>$type, 'id'=>$id, 'price'=>$price->price]);
    }

    public function process(Request $request)
    {
        $twoCheckOut = TwoCheckoutAccount::find(1);
        File::requireOnce(app_path() . "/Twocheckout/lib/Twocheckout.php");
        Twocheckout::verifySSL(false);

        Twocheckout::privateKey($twoCheckOut->private_key);
        Twocheckout::sellerId($twoCheckOut->sellerid);
        if ($twoCheckOut->mode == "sandbox")
             Twocheckout::sandbox(true);

         $payble_product_type = $request->payble_product_type;
         $payble_product_id = $request->payble_product_id;

         $price = Price::where('priceable', '=', $payble_product_type)->firstOrFail();


       try {
        $charge = Twocheckout_Charge::auth(array(
            "merchantOrderId" => ucfirst($payble_product_type)."#".$payble_product_id,
            "token"      => $_POST['token'],

            $payment->total_2co = $charge['response']['total'];
            $payment->save();

        }
    } catch (Twocheckout_Error $e) {print_r($e->getMessage());}

    }
