寫本文章的目的是為了記錄工作中遇到的問題,方便以後遇到可以迅速解決問題
H5手機網站接入支付寶的支付介面,推薦使用支付寶提供的SDK來快速開發
我使用的是SDK開發
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 = "***";
這裡的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");//非同步請求 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; }
具體發送給支付寶的參數,自行去查看
執行方法後,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的方式非同步請求你的SetNotifyUrl的地址
這個SetNotifyUrl的地址必須要外網可以訪問,支付寶的請求才能進來
買家支付成功,商家修改訂單狀態和資料庫的操作,都在非同步請求中執行
同步請求
public ActionResult AlipayPayResult() { ViewBag.result = "success"; return View("PayResult"); }

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; }
非同步請求:
