ICanPay介绍

---

ICanPay是一个提供了多个支付网关支付处理的类库，使用ICanPay可以简化订单的创建、查询跟接收网关返回的支付通知。

ICanPay目前实现了4家支付网关，你可以通过实现抽象基类来支持更多的网关。

目前支持的支付网关有：支付宝(Alipay)、微信支付(Wechatpay)、财付通(Tenpay)、易宝(Yeepay)。

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 List<GatewayBase>();
			
            // 设置商户数据
            var alipayMerchant = new Alipay.Merchant
            {
                AppId = "123456",
                NotifyUrl = "http://localhost:61337/Notify",
                ReturnUrl = "http://localhost:61337/Return",
                AlipayPublicKey = "Varorbc",
                Privatekey = "Varorbc"
            };
			
            var alipayGateway = new AlipayGateway(alipayMerchant)
            {
                GatewayTradeType = GatewayTradeType.Web
            };

            gateways.Add(alipayGateway);
        });
    }

	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;
    using System.Collections.Generic;

    namespace ICanPay.Demo.Controllers
    {
		public class PaymentController : Controller
		{
			private ICollection<GatewayBase> gatewayList;
			public PaymentController(ICollection<GatewayBase> gatewayList)
			{
				this.gatewayList = gatewayList;
			}

			public IActionResult Index()
			{

				string content = CreateAlipayOrder();

				return Content(content);
			}

			/// <summary>
			/// 创建支付宝的支付订单
			/// </summary>
			private string CreateAlipayOrder()
			{
				Alipay.Order order = new Alipay.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 = gatewayList.GetGateway(GatewayType.Alipay);
				gateway.GatewayTradeType = GatewayTradeType.App;

				PaymentSetting paymentSetting = new PaymentSetting(gateway, order);
				return paymentSetting.Payment();
			}	
		}
	}

再创建通知控制类：

    using ICanPay.Alipay;
    using ICanPay.Core;
    using Microsoft.AspNetCore.Mvc;
    using System.Collections.Generic;
    using System.Threading.Tasks;

    namespace ICanPay.Demo.Controllers
    {
		public class NotifyController : Controller
		{
			private ICollection<GatewayBase> gatewayList;
			public NotifyController(ICollection<GatewayBase> gatewayList)
			{
				this.gatewayList = gatewayList;
			}

			public async Task Index()
			{
				// 订阅支付通知事件
				PaymentNotify notify = new PaymentNotify(gatewayList);
				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 = (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
			}
		}
	}
