前言

Day 9,10 我們知道要傳哪些參數給 ECPay, 今天我們來看如何在架構裡 導入 ECPay的服務。目前先嘗試最直覺的做法，可能都還有很大的進步空間。

P.S. ECpay 沒有退款的測試環境 因此沒有繼續做下去

• 我們在PaymentController.php 中的 payByWebsite 函式將 ECPay所需的參數整理好:

    include('ECPay.Payment.Integration.php');
        try {
            
            $obj = new ECPay_AllInOne();
       
            //服務參數
            $obj->ServiceURL  = "https://payment-stage.ecpay.com.tw/Cashier/AioCheckOut/V5";  //服務位置
            $obj->HashKey     = '5294y06JbISpM5x9' ;                                          //測試用Hashkey，請自行帶入ECPay提供的HashKey
            $obj->HashIV      = 'v77hoKGq4kWxNNIS' ;                                          //測試用HashIV，請自行帶入ECPay提供的HashIV
            $obj->MerchantID  = '2000214';                                                    //測試用MerchantID，請自行帶入ECPay提供的MerchantID
            $obj->EncryptType = '1';                                                          //CheckMacValue加密類型，請固定填入1，使用SHA256加密
    
    
            //基本參數(依系統調整)
            $MerchantTradeNo = "Test".time() ;
            $obj->Send['ReturnURL']         = "http://www.ecpay.com.tw/receive.php" ;     //付款完成通知回傳的網址
            $obj->Send['MerchantTradeNo']   = $MerchantTradeNo;                           //訂單編號
            $obj->Send['MerchantTradeDate'] = date('Y/m/d H:i:s');                        //交易時間
            $obj->Send['TotalAmount']       = 2000;                                       //交易金額
            $obj->Send['TradeDesc']         = "good to drink" ;                           //交易描述
            $obj->Send['ChoosePayment']     = ECPay_PaymentMethod::ALL ;                  //付款方式:全功能
            
            
    //訂單的商品資料
    array_push($obj->Send['Items'], array(
        'Name'  => "商品名稱",
        'Price'  => (int)1000,
        'Currency'  => "元",
        'Quantity'  => (int) "1",
        'URL'  => ""));

    //產生訂單(auto submit至ECPay)
    $obj->CheckOut();
    
    
        }catch (Exception $e) {
            echo $e->getMessage();
        }  

• 在 OrderController.php 中取出訂單的商品資訊，以下兩種方法結果相同：

$order_with = Order::with(['items.product', 'items.productSku'])->where('id', $order['id'])->first();

$order_info = $order->load(['items.product','items.productSku']);

• load 是底層 Model 寫好的函式
  vendor/laravel/framework/src/Illuminate/Database/Eloquent/Model.php

public function load($relations)
{
    $query = $this->newQueryWithoutRelationships()->with(
        is_string($relations) ? func_get_args() : $relations
    );

    $query->eagerLoadRelations([$this]);

    return $this;
}

• 取出來的結果如下：
