如何使用

首先在Startup文件中添加如下方法：

	public void ConfigureServices(IServiceCollection services)
	{
		services.AddICanPay(a =>
		{
			var gateways = new Gateways();

			// 设置商户数据
			var alipayMerchant = new Alipay.Merchant
			{
				AppId = "2017093009005992",
				NotifyUrl = "http://localhost:61337/Notify",
				ReturnUrl = "http://localhost:61337/Return",
				AlipayPublicKey = "Varorbc",
				Privatekey = "Varorbc"
			};

			var wechatpayMerchant = new Wechatpay.Merchant
			{
				AppId = "wx2428e34e0e7dc6ef",
				MchId = "1233410002",
				Key = "e10adc3849ba56abbe56e056f20f883e",
				AppSecret = "51c56b886b5be869567dd389b3e5d1d6",
				SslCertPath = "Certs/apiclient_cert.p12",
				SslCertPassword = "1233410002",
				NotifyUrl = "http://localhost:61337/Notify"
			};

			gateways.Add(new AlipayGateway(alipayMerchant));
			gateways.Add(new WechatpayGataway(wechatpayMerchant));

			return gateways;
		});
	}

	public void Configure(IApplicationBuilder app, IHostingEnvironment env)
	{
		app.UseICanPay();
	}

然后创建支付控制类：

	using ICanPay.Alipay;
	using ICanPay.Core;
	using Microsoft.AspNetCore.Mvc;

	namespace ICanPay.Demo.Controllers
	{
		public class PaymentController : Controller
		{
			private IGateways gateways;
			public PaymentController(IGateways gateways)
			{
				this.gateways = gateways;
			}

			public IActionResult Index()
			{
				string content = CreateAlipayOrder();

				return Content(content);
			}

			/// <summary>
			/// 创建支付宝的支付订单
			/// </summary>
			private string CreateAlipayOrder()
			{
				var order = new Order()
				{
					Amount = 0.01,
					OutTradeNo = "35",
					Subject = "测测看支付宝",
					Body = "1234",
					ExtendParams = new ExtendParam()
					{
						HbFqNum = "3"
					},
					GoodsDetail = new Goods[] {
						new Goods()
						{
							Id = "12"
						}
					}
				};

				var gateway = gateways.Get(GatewayType.Alipay, GatewayTradeType.Web);

				return gateway.Payment(order);
			}
		}
	}

再创建通知控制类：

    using ICanPay.Core;
	using Microsoft.AspNetCore.Mvc;
	using System.Threading.Tasks;

	namespace ICanPay.Demo.Controllers
	{
		public class NotifyController : Controller
		{
			private IGateways gateways;
			public NotifyController(IGateways gateways)
			{
				this.gateways = gateways;
			}

			public async Task Index()
			{
				// 订阅支付通知事件
				PaymentNotify notify = new PaymentNotify(gateways);
				notify.PaymentSucceed += Notify_PaymentSucceed;
				notify.PaymentFailed += Notify_PaymentFailed;
				notify.UnknownGateway += Notify_UnknownGateway;

				// 接收并处理支付通知
				await notify.ReceivedAsync();
			}

			private void Notify_PaymentSucceed(object sender, PaymentSucceedEventArgs e)
			{
				// 支付成功时时的处理代码
				if (e.GatewayType == GatewayType.Alipay)
				{
					var alipayNotify = (Alipay.Notify)e.Notify;
				}
			}

			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
			}
		}
	}
