ASP.NET Core2.0 環境下MVC模式的支付寶PC網站支付接口-沙箱環境開發測試

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
