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;

/// <summary>
/// 支付宝支付
/// </summary>
/// <param name="amount">金额</param>
/// <param name="userId">用户Id</param>
/// <returns></returns>
[HttpPost]
public async Task<IActionResult> AliPaymentAsync(string amount,string userId)
{
    try
    {
        SenparcTrace.Log($"amount---{amount},userId----{userId}");
        PaymentService paymentService = new PaymentService();
        var obj = await paymentService.PaymentParam(amount, userId);
        return Success(obj);
    }
    catch (Exception ex)
    {
        return Fail(ex.Message);
    }
}

5.建立PaymentService

        /// <summary>

        public async Task<object> PaymentParam(string amount,string userId)
        {
            try
            {
                //实例化具体API对应的request类,类名称和接口名称对应,当前调用接口名称如：alipay.trade.app.pay
                AlipayTradeAppPayRequest request = new AlipayTradeAppPayRequest();
                //SDK已经封装掉了公共参数，这里只需要传入业务参数。以下方法为sdk的model入参方式(model和biz_content同时存在的情况下取biz_content)。
                AlipayTradeAppPayModel model = new AlipayTradeAppPayModel();
                model.Body = "购买会员," + userId;
                string strOutTradeNo = DateTime.Now.ToString("yyyyMMddHHmmss");
                model.OutTradeNo = strOutTradeNo;
                model.Subject = "购买会员";

                if (!string.IsNullOrEmpty(amount))
                {
                    model.TotalAmount = amount;
                }
                else
                {
                    model.TotalAmount = "0.01";
                }
                model.ProductCode = "QUICK_MSECURITY_PAY";
                model.TimeoutExpress = "30m";
                request.SetBizModel(model);
                request.SetNotifyUrl("http://www.alibaba.com/api/alipay/notice");
                //这里和普通的接口调用不同，使用的是sdkExecute
                AlipayTradeAppPayResponse response = client.SdkExecute(request);
                //HttpUtility.HtmlEncode是为了输出到页面时防止被浏览器将关键参数html转义，实际打印到日志以及http传输不会有这个问题
                SenparcTrace.Log($"支付宝支付结果信息为未转义-----{response.Body}");
                SenparcTrace.Log($"支付宝支付结果信息为-----{HttpUtility.HtmlEncode(response.Body)}");
                return new BaseResult<object>(200,"请求成功", HttpUtility.HtmlEncode(response.Body).Replace("&amp;", "&"));
            }
            catch (Exception ex)
            {
                return new BaseResult<object>(201, "请求失败", ex.Message);
            }
        }

    }

}

6.调用代码返回数据（即4中返回的obj的数据）给前端

7.前端拿数据吊起支付
