NCF 如何写微信支付中的小程序支付

简介

上一篇给大家说了APP支付的对接，今天我们来使用NCF快速的对接小程序支付

今天我们讲解到的是微信支付V2开发文档中的使用方法

参考文档

微信支付V2开发文档：https://pay.weixin.qq.com/wiki/doc/api/index.html

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

4.建立自己的Controller，并创建接口方法

5.调用代码返回数据给前端

6.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>
/// 微信小程序支付
/// </summary>
/// <param name="openId">用户的微信OpenId</param>
/// <param name="userId">用户Id</param>
/// <param name="body">内容</param>
/// <param name="totalFee">支付的总金额</param>
/// <returns></returns>
[HttpPost]
public async Task<IActionResult> WxSPPayAsync(string openId,string userId, string body, int totalFee)
{
    try
    {
        //ML 方案
        WechatPayHelper wxpay = new WechatPayHelper();
        WechatPaymentParam wxpayParam = new WechatPaymentParam();
        wxpayParam.appid = "wx2y0svtzsngwduix6";
        wxpayParam.mch_id = "0165355078";
        wxpayParam.attach = $"userId={userId};totalFee={totalFee.ToString()}";
        wxpayParam.body = body;
        wxpayParam.total_fee = totalFee.ToString();
        wxpayParam.notify_url = "https://www.weixin.com/api/v1/payment/wxSPNotifyUrl";
        wxpayParam.trade_type = "JSAPI";
        wxpayParam.openid = openId;
        string strOutTradeNo = "";
        var result = wxpay.Payment(wxpayParam, "5hJpKkSaOoWVqET1Gfl7Q3RUEBLTu9kP", out strOutTradeNo);
        SenparcTrace.Log($"result----{result},sign={strOutTradeNo}");
        result = result.Replace("<![CDATA[", "").Replace("]]>", "").Replace("
", "");
        DataTable dtWxPayResponse = XMLHelper.XMLToDataTable(result);
        var response = dtWxPayResponse.ToJson().Replace("}]", $","timestamp":"{DateTimeHelper.ConvertToJavaScriptUnix(DateTime.Now)}"}}]");

        MakeCallMiniProgramPaymentParam mcmppp = new MakeCallMiniProgramPaymentParam();
        mcmppp.appId = "wx2y0svtzsngwduix6";
        mcmppp.package = $"prepay_id={dtWxPayResponse.Rows[0]["prepay_id"].ToString()}";
        mcmppp.nonceStr = "";
        mcmppp.timeStamp = "";
        string strSign = "";
        var data = wxpay.MakeCallMiniProgramPayment(mcmppp, "5hJpKkSaOoWVqET1Gfl7Q3RUEBLTu9kP", out strSign);
        string rp = XMLHelper.XMLToDataTable(WechatPayHelper.FormatParamToXML(data)).ToJson();

        return Success(rp);
    }
    catch (Exception ex)
    {
        return Fail(ex.Message);
    }
}

5.调用代码返回数据（即4中返回的rp的数据）给前端

6.前端拿数据吊起支付
