https://github.com/hiihellox10/ICanPay?統一支付網關。對原代碼優化。支持NET46和NETSTANDARD2_0。支持支付寶，微信，銀聯支付渠道通過Web，App，Wap，QRCode方式支付。簡化訂單的創建、查詢、退款跟接收網關返回的支付通知等功能

初始網關信息

NET46，需依賴AuotoFac組件

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 注冊依賴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（網站支付）

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（手機網站支付）

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（二維碼支付）

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（手機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（查詢訂單）

public?void?QueryOrder(GatewayType gatewayType)?{
var gateway = gateways.Get(gatewayType);
var querySetting = new PaymentSetting(gateway);
// 查詢時需要設置訂單的Id與金額，在查詢結果中將會核對訂單的Id與金額，如果不相符會返回查詢失敗。querySetting.Order.OrderNo = "20";querySetting.Order.OrderAmount = 0.01;
if (querySetting.QueryNow()){ // 訂單已支付}}

Refund（退款和退款查詢）

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（異步通知）

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()?{ // 接收并處理支付通知notify.Received(PaymentNotifyMethod.ServerNotify);}

public?void?AutoReturn()?{ // 接收并處理支付通知notify.Received(PaymentNotifyMethod.AutoReturn);}
private?void?notify_PaymentSucceed(object?sender, PaymentSucceedEventArgs e)?{
// 支付成功時時的處理代碼if (e.PaymentNotifyMethod == PaymentNotifyMethod.AutoReturn){ // 當前是用戶的瀏覽器自動返回時顯示充值成功頁面} else{ // 支付結果的發送方式，以服務端接收為準}}

private?void?notify_PaymentFailed(object?sender, PaymentFailedEventArgs e)?{
// 支付失敗時的處理代碼}
private?void?notify_UnknownGateway(object?sender, UnknownGatewayEventArgs e)?{
// 無法識別支付網關時的處理代碼}
