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 + "&notify_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modelAlipayTradePagePayModel 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 并非公網或域名地址 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IDstring notifyId = NotifyArray["notify_id"];try{ if (NotifyArray.Count != 0){ //驗簽以及驗證合作伙伴IDbool 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
