AllPay(欧付宝)支付接口集成

2023-12-01

AllPay,http://www.allpay.com.tw/,欧付宝是台湾知名的第三方支付公司,拥有丰富的支付模式(支持和支付宝、财付通),只需要一次对接,各种支付模式均可使用。

接口编写SDK:http://www.allpay.com.tw/Service/API_Help?Anchor=AnchorDoc

官方提供了比较完整的SDK,里面有丰富的代码,这里只讲需要注意的地方:

1.欧付宝提供若干支付模式,可以再接口中指定(不给用户选择的机会);也可以在接口中设置ALL,等到付款的时候让用户选择

2.确定支付模式后,便可以生成订单,然后等待支付

3.支付结果的确认是Server静默方式通知的,非URL跳转的方式,这点类似PayPal的Classic模式

4.提供沙箱模式http://vendor-stage.allpay.com.tw,用户名StageTest,密码Test1234,在沙箱中可以任意下订单,模拟支付等等

5.正式模式的后台http://vendor.allpay.com.tw同样支持模拟付款的方式

6.支付结果接收service,注意需要验证来源,也就是CheckMacValue,验证方法后面给出

7.如果接口中不指定支付模式,oPayment.Send.ChoosePayment = PaymentMethod.ALL; 即使客户不选择支付宝支付,那么也需要将支付宝的支付选项填入

oPayment.SendExtend.PhoneNo = "";
oPayment.SendExtend.Email = "";
oPayment.SendExtend.UserName = "";

因为这三项是必填字段,注意是SendExtend。

8.ReturnURL 為Server 端的回應,歐付寶Server會直接將付款結果送到您指定的ReturnURL

   OrderResultURL 則為 Client 端的回應,我們會將使用者的畫面轉導到您指定的OrderResultURL

   ClientBackURL 主要的功能,是在交易完成的頁面中,若廠商端有設定網址,則在該頁面上會出現「返回商店」的按鈕,當消費者點選後,會導到所設定的網址。

9.MerchantTradeNo测试的时候如果两笔都是一样的,会导致第二次创建订单失败,这个要注意,每次最好用随机数


下面是支付界面,传入订单编号,通过调用AllPay接口,会默认跳转到AllPay去支付
public ActionResult PaymentByAllPay(Guid BillCode)
        {
            List<string> enErrors = new List<string>();

支付确认接口实现:

                // 取回所有資料 
                if (enErrors.Count() == 0)
                {         /* 支付後的回傳的基本參數 */
