static string serverUrl = "https://openapi.alipaydev.com/gateway.do"; static string app_id = "**"; //开发者的应用ID static string format = "JSON"; static string charset = "utf-8"; static string sign_type = "RSA2"; //签名格式 static string version = "1.0"; string UID = "2088102169707816";//卖家支付宝账户号 //商户私钥 static string merchant_private_key = "***"; //支付宝公钥 static string alipay_public_key = "***";
这里的app_id,merchant_private_key,alipay_public_key 我就没有列出来了，获取的方法需要自己去支付宝平台完成一些操作进行获取
在用户点击网站付款时，我们需要唤醒支付宝，来进行支付
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= "" + PathLogic1.RootDomain; request.SetReturnUrl(address+ "/WebPay/AlipayPayResult");//同步请求 request.SetNotifyUrl(address + "/WebPay/AsyncPay");//异步请求 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; }
具体发送给支付宝的参数，自行去查看
执行方法后，买家输入自己的支付宝账号密码进行支付，支付成功的结果，支付宝会以post的方式异步请求你的SetNotifyUrl的地址
这个SetNotifyUrl的地址必须要外网可以访问，支付宝的请求才能进来
买家支付成功，商家修改订单状态和数据库的操作，都在异步请求中执行
同步请求
public ActionResult AlipayPayResult() { ViewBag.result = "success"; return View("PayResult"); }

异步请求：
