ASP.NET Core2.0 环境下MVC模式的支付宝PC网站支付接口-沙箱环境开发测试

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 + "&notify_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modelAlipayTradePagePayModel 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

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IDstring notifyId = NotifyArray["notify_id"];try{ if (NotifyArray.Count != 0){   //验签以及验证合作伙伴IDbool 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);

 8.配置系统启动项目信息

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
