PHP新手30天實戰金流, Laravel6

前言

• ECPay 退款，只有信用卡可以直接退，其餘收款方式皆需要賣家自行處理
  

• ECPay 信用卡退款函式

  //信用卡關帳/退刷/取消/放棄的方法
      function DoAction() {
          return $arFeedback = ECPay_DoAction::CheckOut(array_merge($this->Action,
          array('MerchantID' => $this->MerchantID, 'EncryptType' => $this->EncryptType)
          ) ,
          $this->HashKey ,$this->HashIV ,$this->ServiceURL);
      }
  

  1. 若要執行關帳時，參數請帶：C (綠界系統自動關帳時間 20:00)
  2. 若要執行取消時，參數請帶：E (取消關帳)
  3. 若要執行退刷時，參數請帶：R (已關帳後)
  4. 若要執行放棄時，參數請帶：N (尚未關帳前)

• 第三方信用卡刷退比較
  支付連 PChomePay：可全部刷退 / 部分刷退(每日次數無限制)
  綠界科技 ECPay：可全部刷退 / 部分刷退(每日次數無限制)
  藍新金流 NewebPay：可全部刷退 / 部分刷退(每日一次)

退款 button

axios.post('{{ route('order.applyRefund', $order) }}', { reason: input }).then(function () {
            swal('申請退款成功', '', 'success').then(function () {
              location.reload();
            });
          })

OrderController

• 更新訂單狀態、呼叫 PaymentController

public function applyRefund(Order $order, ApplyRefundRequest $request)
{
    $this->authorize('own', $order);
        
    try {
            $paymentController = new PaymentController();
            $paymentController->refund($order, $request);
        } catch (\Throwable $th) {
            //throw $th;
            $out->writeln("error: ".$th);
        }
        
    if (!$order->paid_at) {
            throw new InvalidRequestException('該訂單未支付，不可退款');
        }
        if ($order->refund_status !== Order::REFUND_STATUS_PENDING) {
            throw new InvalidRequestException('該訂單已經申請過退款，請勿重複申請');
        }

        $extra = $order->extra ? : [];
        $extra['refund_reason'] = $request->input('reason');

        $order->update([
            'refund_status' => Order::REFUND_STATUS_APPLIED,
            'extra' => $extra,
        ]);
        

        return $order;
}

PaymentController - refund 函式

• 請求 ECPay 處理退款

1. 一樣建立 ECPay_AllInOne 實體

$obj = new ECPay_AllInOne();

2. ECPay 關帳時間為 20 點，我們以此判斷要執行"取消"或是"刷退"動作

$ThatTime ="20:00:00";
    if (time() >= strtotime($ThatTime)) {
        $action = 'R';
    }else {
        $action = 'N';
    }
$obj->DoAction();

3. 退款所需參數都有給

$the_action_arr =array(
    'MerchantTradeNo' => $order['payment_no'],
    'TradeNo' => $order['trade_no'],
    'Action' => $action,
    'TotalAmount' => $order['total_amount']
);

$capture = array(
    'MerchantTradeNo' => $order['payment_no'],
    'CaptureAMT' => 0,
    'UserRefundAMT' => 0,
    'PlatformID' => ''
);

$tradeNo = array(
    'DateType' => '',
    'BeginDate' => $order['trade_no'],
    'EndDate' => '',
    'MediaFormated' => ''
);
$obj->Capture = $capture; 
            $obj->TradeNo = $tradeNo; 
            $obj->Action = $the_action_arr; 
    

5. 結果 error :
   "Merchant=2000214&MerchantTradeNo=&TradeNo=&RtnCode=10200074&RtnMsg=\u627e\u4e0d\u5230\u52a0\u5bc6\u91d1\u9470\uff0c\u8acb\u78ba\u8a8d\u662f\u5426\u6709\u7533\u8acb\u958b\u901a\u6b64\u4ed8\u6b3e\u65b9\u5f0f"
   10200074 找不到加密金鑰，請確認是否有申請開通此付款方式

不知道原因
