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 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));
        });
    }

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
		}
	}
}
