NCF 如何写支付宝支付中的APP支付

简介

今天我们就来使用NCF框架对接一下支付宝支付

参考文档

支付宝支付开发文档：https://opendocs.alipay.com/open/204

NCF仓库地址：https://github.com/NeuCharFramework/NCF (要Star哦)

步骤

1.下载NCF

2.创建自己的XNCF模块

3.引用Nuget包ML.ThirdParty & ML.Common.SDK & AopSdk

4.建立自己的Controller，并创建接口方法

5.建立PaymentService

6.调用代码返回数据给前端

7.前端拿数据吊起支付

案例

1.直接到Github上下载NCF的源码master分支

2.请参考NCF开发文档中的创建XNCF模块

3.项目中引入

1     <ItemGroup>
2         <PackageReference Include="ML.Common.SDK" Version="1.0.2.8" />
3         <PackageReference Include="ML.ThirdParty" Version="1.0.2" />
4     </ItemGroup>

4.建立自己的Controller，并创建方法

1 //引用相关命名空间
2 using ML.Common.SDK;
3 using ML.ThirdParty.Wechat;

 1 /// <summary>
 2 /// 支付宝支付
 3 /// </summary>
 4 /// <param name="amount">金额</param>
 5 /// <param name="userId">用户Id</param>
 6 /// <returns></returns>
 7 [HttpPost]
 8 public async Task<IActionResult> AliPaymentAsync(string amount,string userId)
 9 {
10     try
11     {
12         SenparcTrace.Log($"amount---{amount},userId----{userId}");
13         PaymentService paymentService = new PaymentService();
14         var obj = await paymentService.PaymentParam(amount, userId);
15         return Success(obj);
16     }
17     catch (Exception ex)
18     {
19         return Fail(ex.Message);
20     }
21 }

5.建立PaymentService
