我使用的是SDK開發(fā)
引用命名空間
using Aop.Api; using Aop.Api.Request; using Aop.Api.Response; using Aop.Api.Util;
首頁需要定義一些常量
static string serverUrl = "https://openapi.alipaydev.com/gateway.do"; static string app_id = "**"; //開發(fā)者的應用ID static string format = "JSON"; static string charset = "utf-8"; static string sign_type = "RSA2"; //簽名格式 static string version = "1.0"; string UID = "2088102169707816";//賣家支付寶賬戶號 //商戶私鑰 static string merchant_private_key = "***"; //支付寶公鑰 static string alipay_public_key = "***";
這里的app_id,merchant_private_key,alipay_public_key 我就沒有列出來了,獲取的方法需要自己去支付寶平臺完成一些操作進行獲取
在用戶點擊網(wǎng)站付款時,我們需要喚醒支付寶,來進行支付
public string H5RequestPayWay(OrderPO order) { IAopClient client = new DefaultAopClient(serverUrl, app_id, merchant_private_key, format, version, sign_type, alipay_public_key, charset, false); AlipayTradeWapPayRequest request = new AlipayTradeWapPayRequest(); string address= "http://m." + PathLogic1.RootDomain; request.SetReturnUrl(address+ "/WebPay/AlipayPayResult");//同步請求 request.SetNotifyUrl(address + "/WebPay/AsyncPay");//異步請求 var lstDetail = Context.Data.OrderDetail.Where(x => x.OrderNo == order.OrderNo).ToSelectList(x=>new { x.SkuName}); StringBuilder sb = new StringBuilder(); for (int i = 0; i < lstDetail.Count(); i++) { sb.Append(lstDetail[i].SkuName + ","); } request.BizContent = "{" + "\"body\":\""+sb.ToString().Substring(0,sb.Length-1)+"\"," + "\"subject\":\"袋鼠巴巴商品支付\"," + "\"out_trade_no\":\""+order.OrderNo+"\"," + "\"timeout_express\":\"90m\"," + "\"total_amount\":"+(order.TotalAmount.Value+order.TotalFreight.Value)+"," + "\"product_code\":\"QUICK_WAP_PAY\"" + " }"; AlipayTradeWapPayResponse response = client.pageExecute(request); return response.Body; }
具體發(fā)送給支付寶的參數(shù),自行去查看
執(zhí)行方法后,買家輸入自己的支付寶賬號密碼進行支付,支付成功的結果,支付寶會以post的方式異步請求你的SetNotifyUrl的地址
這個SetNotifyUrl的地址必須要外網(wǎng)可以訪問,支付寶的請求才能進來
買家支付成功,商家修改訂單狀態(tài)和數(shù)據(jù)庫的操作,都在異步請求中執(zhí)行
同步請求
public ActionResult AlipayPayResult() { ViewBag.result = "success"; return View("PayResult"); }
/// <summary> /// 驗證通知數(shù)據(jù)的正確性 /// </summary> /// <param name="out_trade_no"></param> /// <param name="total_amount"></param> /// <param name="seller_id"></param> /// <returns></returns> private SortedDictionary<string, string> GetRequestPost() { int i = 0; SortedDictionary<string, string> sArray = new SortedDictionary<string, string>(); NameValueCollection coll; //Load Form variables into NameValueCollection variable. coll = Request.Form; // Get names of all forms into a string array. String[] requestItem = coll.AllKeys; for (i = 0; i < requestItem.Length; i++) { sArray.Add(requestItem[i], Request.Form[requestItem[i]]); } return sArray; }
/// <summary> /// 驗簽 /// </summary> /// <param name="inputPara"></param> /// <returns></returns> public Boolean Verify(SortedDictionary<string, string> inputPara) { Dictionary<string, string> sPara = new Dictionary<string, string>(); Boolean verifyResult = AlipaySignature.RSACheckV1(inputPara, alipay_public_key, charset,sign_type,false); return verifyResult; }
異步請求:
[HttpPost] public void AsyncPay() { SortedDictionary<string, string> sPara = GetRequestPost();//將post請求過來的參數(shù)傳化為SortedDictionary if (sPara.Count > 0) { AlipayTradeWayPayServer pay = new AlipayTradeWayPayServer(); Boolean VerifyResult = pay.Verify(sPara);//驗簽if (VerifyResult) { try { //商戶訂單號 string out_trade_no = Request.Form["out_trade_no"]; //支付寶交易號 string trade_no = Request.Form["trade_no"]; //支付金額 decimal total_amount = Request.Form["total_amount"].ConvertType(Decimal.Zero); //實收金額 //decimal receipt_amount = Request.Form["receipt_amount"].ConvertType(Decimal.Zero); //交易狀態(tài) string trade_status = Request.Form["trade_status"]; //賣家支付寶賬號 string seller_id = Request.Form["seller_id"]; //商品描述 string body = Request.Form["body"]; //交易創(chuàng)建時間 DateTime gmt_create = DateTime.Parse(Request.Form["gmt_create"]); //交易付款時間 DateTime gmt_payment = DateTime.Parse(Request.Form["gmt_payment"]); string appid = Request.Form["app_id"]; WriteError("驗證參數(shù)開始"); Boolean DataValidity = pay.CheckInform(out_trade_no, total_amount, seller_id, appid);//商家判斷參數(shù)時候是否匹配if (DataValidity) { if (Request.Form["trade_status"] == "TRADE_FINISHED") { AlipayWayPayPO model = CreateAlipayWayPay(out_trade_no, trade_no, trade_status, gmt_create, gmt_payment); pay.PaySuccess(out_trade_no, model, Server.MapPath("~/" + DateTime.Today.ToString("yyMMdd") + ".txt"));//修改訂單 //注意: //退款日期超過可退款期限后(如三個月可退款),支付寶系統(tǒng)發(fā)送該交易狀態(tài)通知 } else if (Request.Form["trade_status"] == "TRADE_SUCCESS") { AlipayWayPayPO model = CreateAlipayWayPay(out_trade_no, trade_no, trade_status, gmt_create, gmt_payment); pay.PaySuccess(out_trade_no, model, Server.MapPath("~/" + DateTime.Today.ToString("yyMMdd") + ".txt"));//修改訂單 //注意: //付款完成后,支付寶系統(tǒng)發(fā)送該交易狀態(tài)通知 } else { } //——請根據(jù)您的業(yè)務邏輯來編寫程序(以上代碼僅作參考)—— Response.Write("success"); //請不要修改或刪除 ///////////////////////////////////////////////////////////////////////////////////////////////////////////// } } catch (Exception ex) { } } else//驗證失敗 { Response.Write("fail"); } } else { Response.Write("無通知參數(shù)"); } }
