H5手机网站接入支付宝的支付接口,推荐使用支付宝提供的SDK来快速开发
我使用的是SDK开发
引用命名空间
using Aop.Api; using Aop.Api.Request; using Aop.Api.Response; using Aop.Api.Util;
首页需要定义一些常量
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= http://m. + 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); }
/// <summary> /// 验证通知数据的正确性 /// </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> /// 验签 /// </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; }
异步请求:
[HttpPost] public void AsyncPay() { SortedDictionary<string, string> sPara = GetRequestPost();//将post请求过来的参数传化为SortedDictionary if (sPara.Count > 0) { AlipayTradeWayPayServer pay = new AlipayTradeWayPayServer(); Boolean VerifyResult = pay.Verify(sPara);//验签if (VerifyResult) { try { //商户订单号 string out_Trade_no = Request.Form[out_Trade_no]; //支付宝交易号 string Trade_no = Request.Form[Trade_no]; //支付金额 decimal total_amount = Request.Form[total_amount].ConvertType(Decimal.Zero); //实收金额 //decimal receipt_amount = Request.Form[receipt_amount].ConvertType(Decimal.Zero); //交易状态 string Trade_status = Request.Form[Trade_status]; //卖家支付宝账号 string seller_id = Request.Form[seller_id]; //商品描述 string body = Request.Form[body]; //交易创建时间 DateTime gmt_create = DateTime.Parse(Request.Form[gmt_create]); //交易付款时间 DateTime gmt_payment = DateTime.Parse(Request.Form[gmt_payment]); string appid = Request.Form[app_id]; WriteError(验证参数开始); Boolean DataValidity = pay.CheckInform(out_Trade_no, total_amount, seller_id, appid);//商家判断参数时候是否匹配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));//修改订单 //注意: //退款日期超过可退款期限后(如三个月可退款),支付宝系统发送该交易状态通知 } 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));//修改订单 //注意: //付款完成后,支付宝系统发送该交易状态通知 } else { } //——请根据您的业务逻辑来编写程序(以上代码仅作参考)—— Response.Write(success); //请不要修改或删除 ///////////////////////////////////////////////////////////////////////////////////////////////////////////// } } catch (Exception ex) { } } else//验证失败 { Response.Write(fail); } } else { Response.Write(无通知参数); } }
