藍新金流 MPG 支付串接任務
你的任務是在用戶的專案中實作藍新金流 MPG 幕前支付功能。
串接 Checklist
完成以下步驟即可完成串接:
- 環境確認 - 確認框架類型與支付方式需求
- 環境變數 - 設定 NEWEBPAY_MERCHANT_ID、HASH_KEY、HASH_IV
- 支付模組 - 建立加密解密與訂單建立功能
- 支付表單 - 建立送出至藍新的 HTML 表單
- 回調處理 - 建立 NotifyURL 與 ReturnURL 端點
- 測試驗證 - 使用測試環境與測試卡號驗證
Step 1: 確認專案環境
詢問用戶:
-
框架類型:你使用什麼框架?
- PHP (Laravel / CodeIgniter / 原生)
- Node.js (Express / Fastify / NestJS)
- Python (Django / Flask / FastAPI)
- 其他
-
支付方式:需要支援哪些支付方式?(可複選)
- 信用卡
- LINE Pay
- Apple Pay / Google Pay
- ATM 轉帳
- 超商代碼/條碼
用戶輸入: $ARGUMENTS
Step 2: 檢查環境變數
搜尋專案中的 .env 或設定檔,確認是否已設定:
NEWEBPAY_MERCHANT_IDNEWEBPAY_HASH_KEYNEWEBPAY_HASH_IV
若未設定,引導用戶設定環境變數。
Step 3: 建立支付模組
根據用戶框架建立支付模組檔案。
建立位置建議:
- Laravel:
app/Services/NewebPayService.php - Express:
services/newebpay.js - Django:
payments/services.py
核心功能:
encrypt(data)- AES256 加密decrypt(data)- AES256 解密generateSha(tradeInfo)- SHA256 簽章createOrder(orderData)- 建立訂單並回傳表單資料handleNotify(payload)- 處理回調通知
Step 4: 建立支付表單頁面
根據框架建立支付表單,需包含:
<form method="post" action="https://ccore.newebpay.com/MPG/mpg_gateway">
<input type="hidden" name="MerchantID" value="{商店代號}">
<input type="hidden" name="TradeInfo" value="{加密資料}">
<input type="hidden" name="TradeSha" value="{SHA256簽章}">
<input type="hidden" name="Version" value="2.3">
<button type="submit">前往付款</button>
</form>
Step 5: 建立回調處理
建立兩個端點:
-
NotifyURL (背景通知):
POST /payment/notify- 接收藍新背景通知
- 解密 TradeInfo
- 更新訂單狀態
- 回應 "OK"
-
ReturnURL (前台返回):
GET/POST /payment/return- 用戶支付完成後導向
- 顯示交易結果
Step 6: 測試驗證
引導用戶進行測試:
- 使用測試環境
https://ccore.newebpay.com - 測試信用卡號:
4000-2211-1111-1111 - 驗證加密解密正確性
- 確認回調可正常接收
