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<AlipayGateway>(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 == typeof(AlipayGateway))
{
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
}
}
}
