ICanPay 统一支付网关

https://github.com/hiihellox10/ICanPay 统一支付网关。对原代码优化。支持NET46和NETSTANDARD2_0。支持支付宝，微信，银联支付渠道通过Web，App，Wap，QRCode方式支付。简化订单的创建、查询、退款跟接收网关返回的支付通知等功能

初始网关信息

NET46，需依赖AuotoFac组件

     var builder = new ContainerBuilder();builder.RegisterControllers(typeof(MvcApplication).Assembly);builder.Register(c =>{                var gateways = new Gateways();gateways.Add(new AlipayGateway(){Merchant = new Merchant(){AppId = ConfigurationManager.AppSettings["alipay.appid"],Partner = ConfigurationManager.AppSettings["alipay.partner"],Email = ConfigurationManager.AppSettings["alipay.seller_email"],Key = ConfigurationManager.AppSettings["alipay.key"],PublicKey = ConfigurationManager.AppSettings["alipay.publicKey"],PrivateKey = ConfigurationManager.AppSettings["alipay.privateKey"],NotifyUrl = new Uri(ConfigurationManager.AppSettings["alipay.notify_url"]),ReturnUrl = new Uri(ConfigurationManager.AppSettings["alipay.return_url"]),}});               return gateways;}).As<IGateways>().InstancePerDependency();            //autofac 注册依赖IContainer container = builder.Build();DependencyResolver.SetResolver(new AutofacDependencyResolver(container));

NETSTANDARD2_0，在Startup初始化

    public void ConfigureServices(IServiceCollection services) {services.AddMvc();services.AddSingleton<IConfiguration>(Configuration);services.AddICanPay(a =>{                var gateways = new Gateways();gateways.Add(new AlipayGateway(){Merchant = new Merchant(){AppId = Configuration["alipay:appid"],Partner = Configuration["alipay:partner"],Email = Configuration["alipay:seller_email"],Key = Configuration["alipay:key"],PublicKey = Configuration["alipay:publicKey"],PrivateKey = Configuration["alipay:privateKey"],NotifyUrl = new Uri(Configuration["alipay:notifyurl"]),ReturnUrl = new Uri(Configuration["alipay:returnurl"]),}});               return gateways;});}

WebPayment（网站支付）

   public void CreateOrder(GatewayType gatewayType) {         
      var gateway = gateways.Get(gatewayType, GatewayTradeType.Web);    
           var paymentSetting = new PaymentSetting(gateway);paymentSetting.Order = new Order(){OrderAmount = 0.01,OrderNo = DateTime.Now.ToString("yyyyMMddhhmmss"),Subject = "WebPayment",PaymentDate = DateTime.Now};paymentSetting.Payment();}

WapPayment（手机网站支付）

    public void CreateOrder(GatewayType gatewayType) {         
       var gateway = gateways.Get(gatewayType, GatewayTradeType.Wap);       
            var paymentSetting = new PaymentSetting(gateway);paymentSetting.Order = new Order(){OrderAmount = 0.01,OrderNo = DateTime.Now.ToString("yyyyMMddhhmmss"),Subject = "WapPayment",PaymentDate = DateTime.Now};paymentSetting.Payment();}

QRCodePayment（二维码支付）

        public void CreateOrder(GatewayType gatewayType) {          
          var gateway = gateways.Get(gatewayType, GatewayTradeType.QRCode);  
          var paymentSetting = new PaymentSetting(gateway);paymentSetting.Order = new Order(){OrderAmount = 0.01,OrderNo = DateTime.Now.ToString("yyyyMMddhhmmss"),Subject = "QRCodePayment",PaymentDate = DateTime.Now};paymentSetting.Payment();}

AppPayment（手机APP支付）

        public JsonResult CreateOrder(GatewayType gatewayType) {    
                var gateway = gateways.Get(gatewayType, GatewayTradeType.APP);   
               var paymentSetting = new PaymentSetting(gateway);paymentSetting.Order = new Order(){OrderAmount = 0.01,OrderNo = DateTime.Now.ToString("yyyyMMddhhmmss"),Subject = "AppPayment",PaymentDate = DateTime.Now};            return Json(paymentSetting.Payment());}

QueryPayment（查询订单）

    public void QueryOrder(GatewayType gatewayType) {       
         var gateway = gateways.Get(gatewayType);          
         var querySetting = new PaymentSetting(gateway);       
       // 查询时需要设置订单的Id与金额，在查询结果中将会核对订单的Id与金额，如果不相符会返回查询失败。querySetting.Order.OrderNo = "20";querySetting.Order.OrderAmount = 0.01;       
            if (querySetting.QueryNow()){                // 订单已支付}}

Refund（退款和退款查询）

    public void CreateRefund(GatewayType gatewayType) {         
       var gateway = gateways.Get(gatewayType);         
          var paymentSetting = new PaymentSetting(gateway);     
            if (paymentSetting.CanRefund){                var refund = new Refund();refund.OutRefundNo = "000000000000000";paymentSetting.BuildRefund(refund);paymentSetting.BuildRefundQuery(refund);}}

Notify（异步通知）

        private readonly IGateways gateways;        
        private PaymentNotify notify;       
         public NotifyController(IGateways gateways) {       
              this.gateways = gateways;notify = new PaymentNotify(gateways.Merchants);notify.PaymentSucceed += new PaymentSucceedEventHandler(notify_PaymentSucceed);notify.PaymentFailed += new PaymentFailedEventHandler(notify_PaymentFailed);notify.UnknownGateway += new UnknownGatewayEventHandler(notify_UnknownGateway);} 
           public void ServerNotify() {          // 接收并处理支付通知notify.Received(PaymentNotifyMethod.ServerNotify);}       
        
         public void AutoReturn() {            // 接收并处理支付通知notify.Received(PaymentNotifyMethod.AutoReturn);}        
        private void notify_PaymentSucceed(object sender, PaymentSucceedEventArgs e) {      
              // 支付成功时时的处理代码if (e.PaymentNotifyMethod == PaymentNotifyMethod.AutoReturn){                // 当前是用户的浏览器自动返回时显示充值成功页面}            else{                // 支付结果的发送方式，以服务端接收为准}}        
        
        private void notify_PaymentFailed(object sender, PaymentFailedEventArgs e) {         
           // 支付失败时的处理代码}       
         private void notify_UnknownGateway(object sender, UnknownGatewayEventArgs e) {         
            // 无法识别支付网关时的处理代码}
