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;
1 /// <summary> 2 /// 微信小程序支付 3 /// </summary> 4 /// <param name="openId">用户的微信OpenId</param> 5 /// <param name="userId">用户Id</param> 6 /// <param name="body">内容</param> 7 /// <param name="totalFee">支付的总金额</param> 8 /// <returns></returns> 9 [HttpPost] 10 public async Task<IActionResult> WxSPPayAsync(string openId,string userId, string body, int totalFee) 11 { 12 try 13 { 14 //ML 方案 15 WechatPayHelper wxpay = new WechatPayHelper(); 16 WechatPaymentParam wxpayParam = new WechatPaymentParam(); 17 wxpayParam.appid = "wx2y0svtzsngwduix6"; 18 wxpayParam.mch_id = "0165355078"; 19 wxpayParam.attach = $"userId={userId};totalFee={totalFee.ToString()}"; 20 wxpayParam.body = body; 21 wxpayParam.total_fee = totalFee.ToString(); 22 wxpayParam.notify_url = "https://www.weixin.com/api/v1/payment/wxSPNotifyUrl"; 23 wxpayParam.trade_type = "JSAPI"; 24 wxpayParam.openid = openId; 25 string strOutTradeNo = ""; 26 var result = wxpay.Payment(wxpayParam, "5hJpKkSaOoWVqET1Gfl7Q3RUEBLTu9kP", out strOutTradeNo); 27 SenparcTrace.Log($"result----{result},sign={strOutTradeNo}"); 28 result = result.Replace("<![CDATA[", "").Replace("]]>", "").Replace("\n", ""); 29 DataTable dtWxPayResponse = XMLHelper.XMLToDataTable(result); 30 var response = dtWxPayResponse.ToJson().Replace("}]", $",\"timestamp\":\"{DateTimeHelper.ConvertToJavaScriptUnix(DateTime.Now)}\"}}]"); 31 32 MakeCallMiniProgramPaymentParam mcmppp = new MakeCallMiniProgramPaymentParam(); 33 mcmppp.appId = "wx2y0svtzsngwduix6"; 34 mcmppp.package = $"prepay_id={dtWxPayResponse.Rows[0]["prepay_id"].ToString()}"; 35 mcmppp.nonceStr = ""; 36 mcmppp.timeStamp = ""; 37 string strSign = ""; 38 var data = wxpay.MakeCallMiniProgramPayment(mcmppp, "5hJpKkSaOoWVqET1Gfl7Q3RUEBLTu9kP", out strSign); 39 string rp = XMLHelper.XMLToDataTable(WechatPayHelper.FormatParamToXML(data)).ToJson(); 40 41 return Success(rp); 42 } 43 catch (Exception ex) 44 { 45 return Fail(ex.Message); 46 } 47 }
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
