1.新建.NET Core web項目
2.Controllers-Models-Views 分三個大部分
3.下載安裝最新sdk
官方的SDK以及Demo都還是.NET Framework的,根據官方文檔說明新建網站后還是需要引用官方SDK的源碼,
在這里直接使用網上一位朋友的用.NET Standard 2.0 進行實現了支付寶服務端SDK,Alipay.AopSdk.Core(github:https://github.com/stulzq/Alipay.AopSdk.Core) ,支持.NET CORE 2.0。
為了使用方便以直接使用Nuget下載安裝,直接使用集成的SDK即可,道理和官網支付寶demo一個樣。
通過Nuget安裝:Install-Package Alipay.AopSdk.Core

4.首先要配置支付寶商戶信息 在這里使用的是沙箱賬號
新建一個配置類基本不用但是后續代碼還是可以方便使用。
Config.cs
using System; using System.Net.Http; using System.Text; using System.Threading.Tasks; namespace Alipay.PCPayment { public class Config { // 應用ID,您的APPID 沙箱 public static string AppId= "2016********3"; /// <summary> /// 合作商戶uid 沙箱 /// </summary> public static string Uid= "208**********2"; // 支付寶網關 沙箱地址 public static string Gatewayurl="https://openapi.alipaydev.com/gateway.do"; // 支付寶網關 生產地址 // public static string Gatewayurl = "https://openapi.alipay.com/gateway.do"; /// <summary> /// 異步通知 處理支付寶接口通知返回 獲取是否是支付寶服務器發來的請求的驗證結果 /// </summary> /// <param name="notifyId">通知驗證ID</param> /// <returns>驗證結果</returns> public static async Task<string> VerifyNotifyAsync(string notifyId) { return await SendAsync(Uid, notifyId); } /// <summary> /// //支付寶消息驗證地址 /// </summary> private const string API_URL = "https://mapi.alipay.com/gateway.do?service=notify_verify&"; /// <summary> /// 獲取是否是支付寶服務器發來的請求的驗證結果 /// </summary> /// <param name="partner">partner 合作身份ID</param> /// <param name="notify_id">通知驗證ID</param> /// <returns>驗證結果</returns> public static async Task<string> SendAsync(string partner, string notify_id) { string strResult; string verifyUrl = API_URL + "partner=" + partner + "¬ify_id=" + notify_id; //獲取遠程服務器ATN結果,驗證是否是支付寶服務器發來的請求 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 = "錯誤信息:" + 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. 添加一個控制器 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網站支付 /// </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 發起支付 public IActionResult Index() { return View(); } /// <summary> /// 發起支付請求 /// </summary> /// <param name="tradeno">外部訂單號,商戶網站訂單系統中唯一的訂單號</param> /// <param name="subject">訂單名稱</param> /// <param name="totalAmout">付款金額</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); // 組裝業務參數model AlipayTradePagePayModel model = new AlipayTradePagePayModel { Body = itemBody, Subject = subject, TotalAmount = totalAmout, OutTradeNo = tradeno, ProductCode = "FAST_INSTANT_TRADE_PAY" }; AlipayTradePagePayRequest request = new AlipayTradePagePayRequest(); // 設置同步回調地址 可以是調試模式地址 並非公網或域名地址 Pay走的是控制器的 request.SetReturnUrl("http://190.120.120.01:110/Pay/Callback"); // 設置異步通知接收地址 必須是公網或域名地址 Pay走的是控制器的方法 request.SetNotifyUrl("http://50.200.50.10:110/Pay/AlipayNotify"); // 將業務model載入到request request.SetBizModel(model); var response = _alipayService.SdkExecute(request); Console.WriteLine($"訂單支付發起成功,訂單號:{tradeno}"); //跳轉支付寶支付 支付網關地址 Response.Redirect(Config.Gatewayurl + "?" + response.Body); } #endregion
支付異步回調通知 使用異步通知來獲取支付結果,異步通知即支付寶主動請求我們提供的地址,我們根據請求數據來校驗,獲取支付結果。 #region 支付異步回調通知 /// <summary> /// 異步通知即支付寶主動請求我們提供的地址,我們根據請求數據來校驗,獲取支付結果。 /// 支付異步回調通知 需配置域名 因為是支付寶主動post請求這個action 所以要通過域名訪問或者公網ip /// </summary>//public async Task<IActionResult> AlipayNotify([FromForm]Dictionary<string,string> NotifyArray) public async Task<IActionResult> AlipayNotify() { /* 實際驗證過程建議商戶添加以下校驗。 1、商戶需要驗證該通知數據中的out_trade_no是否為商戶系統中創建的訂單號, 2、判斷total_amount是否確實為該訂單的實際金額(即商戶訂單創建時的金額), 3、校驗通知中的seller_id(或者seller_email) 是否為out_trade_no這筆單據的對應的操作方(有的時候,一個商戶可能有多個seller_id/seller_email) */ Dictionary<string, string> NotifyArray = GetRequestPost(); //通知驗證ID string notifyId = NotifyArray["notify_id"]; try { if (NotifyArray.Count != 0) { //驗簽以及驗證合作伙伴ID bool flag = _alipayService.RSACheckV1(NotifyArray); if (await Config.VerifyNotifyAsync(notifyId) == "true" && flag) { //交易狀態 if (NotifyArray["trade_status"] == "TRADE_FINISHED" || NotifyArray["trade_status"] == "TRADE_SUCCESS") { if (NotifyArray["app_id"] == Config.AppId) { // 修改支付信息以及狀態 //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 ??

7.支付訂單信息頁面
Index.cshtml 支付請求action POST

8.配置系統啟動項目信息
Startup.cs
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. Use this method to configure the HTTP request pipeline. public void Configure(IApplicationBuilder app, IHostingEnvironment env, ILoggerFactory loggerFactory) { loggerFactory.AddConsole(Configuration.GetSection("Logging")); loggerFactory.AddDebug(); if (env.IsDevelopment()) { app.UseDeveloperExceptionPage(); app.UseBrowserLink(); } else { app.UseExceptionHandler("/Home/Error"); } app.UseStaticFiles(); app.UseMvc(routes => { routes.MapRoute( name: "default", template: "{controller=Home}/{action=Index}/{id?}"); }); } }
appsettings.json
