1.新建.NET Core web项目
2.Controllers-Models-Views 分三个大部分
3.下载安装最新sdk
官方的SDK以及Demo都还是.NET Framework的，根据官方文档说明新建网站后还是需要引用官方SDK的源码，
在这里直接使用网上一位朋友的用.NET Standard 2.0 进行实现了支付宝服务端SDK，Alipay.AopSdk.Core（github:https://github.com/stulzq/Alipay.AopSdk.Core） ，支持.NET CORE 2.0。
为了使用方便以直接使用Nuget下载安装，直接使用集成的SDK即可，道理和官网支付宝demo一个样。
通过Nuget安装：Install-Package Alipay.AopSdk.Core
4.首先要配置支付宝商户信息 在这里使用的是沙箱账号
新建一个配置类基本不用但是后续代码还是可以方便使用。
Config.cs
using System; using System.Net.Http; using System.Text; using System.Threading.Tasks; namespace Alipay.PCPayment { public class Config { // 应用ID,您的APPID 沙箱 public static string AppId= "2016********3"; /// <summary> /// 合作商户uid 沙箱 /// </summary> public static string Uid= "208**********2"; // 支付宝网关 沙箱地址 public static string Gatewayurl="https://openapi.alipaydev.com/gateway.do"; // 支付宝网关 生产地址 // public static string Gatewayurl = "https://openapi.alipay.com/gateway.do"; /// <summary> /// 异步通知 处理支付宝接口通知返回 获取是否是支付宝服务器发来的请求的验证结果 /// </summary> /// <param name="notifyId">通知验证ID</param> /// <returns>验证结果</returns> public static async Task<string> VerifyNotifyAsync(string notifyId) { return await SendAsync(Uid, notifyId); } /// <summary> /// //支付宝消息验证地址 /// </summary> private const string API_URL = "https://mapi.alipay.com/gateway.do?service=notify_verify&"; /// <summary> /// 获取是否是支付宝服务器发来的请求的验证结果 /// </summary> /// <param name="partner">partner 合作身份ID</param> /// <param name="notify_id">通知验证ID</param> /// <returns>验证结果</returns> public static async Task<string> SendAsync(string partner, string notify_id) { string strResult; string verifyUrl = API_URL + "partner=" + partner + "¬ify_id=" + notify_id; //获取远程服务器ATN结果，验证是否是支付宝服务器发来的请求 try { using (var client = new HttpClient()) { //client.Timeout = 120000; var response = await client.GetAsync(verifyUrl); if (response.IsSuccessStatusCode) { byte[] data = await response.Content.ReadAsByteArrayAsync(); Encoding.UTF8.GetString(data); return strResult= "true"; } } } catch (Exception exp) { strResult = "错误信息：" + exp.Message; } return string.Empty; }
public static ContentResult Response_Success(string msg = null)
{
return new ContentResult
{
Content = msg ?? "success"
};
}
public static ContentResult ResponseFail(string msg = null)
{
return new ContentResult
{
Content = msg ?? "fail"
};
} } }
5. 添加一个控制器 PayController
using System; using System.Collections.Generic; using Alipay.AopSdk.AspnetCore; using Alipay.AopSdk.Core; using Alipay.AopSdk.Core.Domain; using Alipay.AopSdk.Core.Request; using Microsoft.AspNetCore.Http; using Microsoft.AspNetCore.Mvc; using System.Threading.Tasks; using Alipay.Demo.PCPayment.Interfaces; using Microsoft.Extensions.Logging; namespace Alipay.PCPayment.Controllers { /// <summary> /// PC网站支付 /// </summary> public class PayController : Controller { private readonly IAlipayService _alipayService; private readonly IAccounts _IAccounts; private readonly ILogger _logger; public PayController(IAlipayService alipayService, ILogger<PayController> logger) { _alipayService = alipayService; _logger = logger; } //_alipayService.Execute(); #region 发起支付 public IActionResult Index() { return View(); } /// <summary> /// 发起支付请求 /// </summary> /// <param name="tradeno">外部订单号，商户网站订单系统中唯一的订单号</param> /// <param name="subject">订单名称</param> /// <param name="totalAmout">付款金额</param> /// <param name="itemBody">商品描述</param> /// <returns></returns> [HttpPost] public void PayRequest(string tradeno, string subject, string totalAmout, string itemBody) { // DefaultAopClient client = new DefaultAopClient(Config.Gatewayurl, Config.AppId, Config.PrivateKey, "json", "2.0", //Config.SignType, Config.AlipayPublicKey, Config.CharSet, false); // 组装业务参数model AlipayTradePagePayModel model = new AlipayTradePagePayModel { Body = itemBody, Subject = subject, TotalAmount = totalAmout, OutTradeNo = tradeno, ProductCode = "FAST_INSTANT_TRADE_PAY" }; AlipayTradePagePayRequest request = new AlipayTradePagePayRequest(); // 设置同步回调地址 可以是调试模式地址 并非公网或域名地址 Pay走的是控制器的 request.SetReturnUrl("http://190.120.120.01:110/Pay/Callback"); // 设置异步通知接收地址 必须是公网或域名地址 Pay走的是控制器的方法 request.SetNotifyUrl("http://50.200.50.10:110/Pay/AlipayNotify"); // 将业务model载入到request request.SetBizModel(model); var response = _alipayService.SdkExecute(request); Console.WriteLine($"订单支付发起成功，订单号：{tradeno}"); //跳转支付宝支付 支付网关地址 Response.Redirect(Config.Gatewayurl + "?" + response.Body); } #endregion
支付异步回调通知 使用异步通知来获取支付结果，异步通知即支付宝主动请求我们提供的地址，我们根据请求数据来校验，获取支付结果。 #region 支付异步回调通知 /// <summary> /// 异步通知即支付宝主动请求我们提供的地址，我们根据请求数据来校验，获取支付结果。 /// 支付异步回调通知 需配置域名 因为是支付宝主动post请求这个action 所以要通过域名访问或者公网ip /// </summary>//public async Task<IActionResult> AlipayNotify([FromForm]Dictionary<string,string> NotifyArray) public async Task<IActionResult> AlipayNotify() { /* 实际验证过程建议商户添加以下校验。 1、商户需要验证该通知数据中的out_trade_no是否为商户系统中创建的订单号， 2、判断total_amount是否确实为该订单的实际金额（即商户订单创建时的金额）， 3、校验通知中的seller_id（或者seller_email) 是否为out_trade_no这笔单据的对应的操作方（有的时候，一个商户可能有多个seller_id/seller_email） */ Dictionary<string, string> NotifyArray = GetRequestPost(); //通知验证ID string notifyId = NotifyArray["notify_id"]; try { if (NotifyArray.Count != 0) { //验签以及验证合作伙伴ID bool flag = _alipayService.RSACheckV1(NotifyArray); if (await Config.VerifyNotifyAsync(notifyId) == "true" && flag) { //交易状态 if (NotifyArray["trade_status"] == "TRADE_FINISHED" || NotifyArray["trade_status"] == "TRADE_SUCCESS") { if (NotifyArray["app_id"] == Config.AppId) { // 修改支付信息以及状态 //return await UpdateAliPayAsyn(NotifyArray); } } await Response.WriteAsync("success"); } else { await Response.WriteAsync("fail"); } } } catch (Exception e) { _logger.LogError("Alipay notify fail, {0}", e); } return View(); //string msg = null; //return new ContentResult //{ // Content = msg ??

public class Startup { public Startup(IConfiguration configuration) { Configuration = configuration; } public IConfiguration Configuration { get; } // This method gets called by the runtime. Use this method to add services to the container. public void ConfigureServices(IServiceCollection services) { services.AddMvc(); Console.WriteLine(Configuration["Alipay:AlipayPublicKey"]); services.AddAlipay(options => { options.AlipayPublicKey = Configuration["Alipay:AlipayPublicKey"]; options.AppId = Configuration["Alipay:AppId"]; options.CharSet = Configuration["Alipay:CharSet"]; options.Gatewayurl = Configuration["Alipay:Gatewayurl"]; options.PrivateKey = Configuration["Alipay:PrivateKey"]; options.SignType = Configuration["Alipay:SignType"]; options.Uid = Configuration["Alipay:Uid"]; }).AddAlipayF2F(); } // This method gets called by the runtime.
