ASP.NET MVC 下使用支付寶支付接口 以及 ASP.NET Core 下相關改造支付

經過nuget首先引用AopSdk.dll 包

下面寫的是 Asp.Net MVC 下相關的支付接口

APP支付

配置客戶端相關的參數，配置成本身的代碼就能夠了

        private string APPID = string.Empty;
        private string APP_PRIVATE_KEY = string.Empty;
        private string ALIPAY_PUBLIC_KEY = string.Empty;
        private string CHARSET = string.Empty;
        IAopClient client;
    

在支付接口構造函數中初始化Client信息

 client = new DefaultAopClient("https://openapi.alipay.com/gateway.do", APPID, APP_PRIVATE_KEY, "json", "1.0", "RSA2", ALIPAY_PUBLIC_KEY, CHARSET, false);

APP發起支付請求

 /// <summary>
        /// App發起支付請求
        /// </summary>
        /// <param name="tradeno">外部訂單號，商戶網站訂單系統中惟一的訂單號</param>
        /// <param name="subject">訂單名稱</param>
        /// <param name="totalAmout">付款金額</param>
        /// <param name="itemBody">商品描述</param>
        [HttpPost]
        public JObject AppPayRequest(string tradeno, string subject, string totalAmout, string itemBody)
        {


            AlipayTradeAppPayRequest request = new AlipayTradeAppPayRequest();
            //SDK已經封裝掉了公共參數，這裏只須要傳入業務參數。如下方法爲sdk的model入參方式(model和biz_content同時存在的狀況下取biz_content)。
            AlipayTradeAppPayModel model = new AlipayTradeAppPayModel();
            model.Body = itemBody; 
            model.Subject = subject;
            model.TotalAmount = totalAmout;
            model.ProductCode = "quick_msecurity_pay";
            model.OutTradeNo = "20170216test01";
            model.TimeoutExpress = "30m";
            request.SetBizModel(model);
            request.SetNotifyUrl("https://xxxxxx/callback");

            //這裏和普通的接口調用不一樣，使用的是sdkExecute
            AlipayTradeAppPayResponse response = client.SdkExecute(request);
            //HttpUtility.HtmlEncode是爲了輸出到頁面時防止被瀏覽器將關鍵參數html轉義，實際打印到日誌以及http傳輸不會有這個問題
            return JObject.Parse(HttpUtility.HtmlEncode(response.Body));
            //頁面輸出的response.Body就是orderString 能夠直接給客戶端請求，無需再作處理。


        }

Web支付調用

            AlipayTradePayModel model = new AlipayTradePayModel();

            model.TimeoutExpress = "30m";
            request.SetBizModel(model);
            request.SetNotifyUrl("https://xxxxxx/callback");
            AlipayTradePayResponse response = client.pageExecute(request); //返回表單信息，js submit
            return JObject.Parse(HttpUtility.HtmlEncode(response.Body));
           


        }

                sArray.Add(requestItem[i], coll.Get(requestItem[i]));
            }
            //一、獲取交易號 在去支付寶校驗知否存在該交易號 以及該交易號的支付狀態

            //二、驗證是不是 咱們本身商戶 回調的訂單信息

            //三、驗證知否金額是不是訂單金額

            //四、業務通知成功 要告知支付寶 不要繼續發動通知回調 ，若是業務處理有異常 記錄訂單日誌

ASP.NET Core 下面的支付，仍是使用此SDK, 把DefaultAopClient 封裝配置下Options 擴展到 IServiceCollection 方法註冊服務便可，後期有時間補上這塊的代碼
