订单查询

用处同V3订单查询,直接上代码:

 1         /// <summary>
 2         /// V2订单查询
 3         /// </summary>
 4         public void QueryOrder()
 5         {
 6             string orderNo = string.Empty;
 7  
 8             WxPayModel model = WxPayModel.Create(orderNo);
 9             OrderQueryMessage message = WeiXinHelper.OrderQuery(model.CreateOrderQueryPackage());
10         }

生成订单查询json方法:

 1         /// <summary>
 2         /// 生成订单查询Json  (已测试通过)
 3         /// </summary>
 4         /// <returns></returns>
 5         public string CreateOrderQueryPackage()
 6         {
 7             Dictionary<string, string> nativeObj = new Dictionary<string, string>();
 8             if (CheckOrderQueryParameters() == false)
 9             {
10                 throw new SDKRuntimeException("生成package参数缺失!");
11             }
12             nativeObj.Add("appid", AppId);
13             nativeObj.Add("package", GetCftPackage());
14             nativeObj.Add("timestamp", ((DateTime.Now.ToUniversalTime().Ticks - 621355968000000000) / 10000000).ToString());
15             nativeObj.Add("app_signature", GetBizSign(nativeObj));
16             nativeObj.Add("sign_method", SignType);
17 
18             var entries = nativeObj.Select(d => string.Format("\"{0}\": \"{1}\"", d.Key, d.Value));
19 
20             return "{" + string.Join(",", entries.ToArray()) + "}";
21         }

 

退款

退款操作只是向财付通发出退款通知,成功与否需要查询:

 1         /// <summary>
 2         /// V2退款
 3         /// </summary>
 4         /// <returns>提交退款结果</returns>
 5         public bool OrderRefund()
 6         {
 7             string orderNo = string.Empty;
 8             string transactionId = string.Empty;
 9             string totalFee = string.Empty;
10             string refundNo = string.Empty;
11             string refundFee = string.Empty;
12 
13             /*
14              TenpayHelper.Refund()方法中  这两段代码是在  管理员账号的密码默认为111111时使用 ,请根据情况修改
15             reqHandler.setParameter("op_user_id", partnerId); //todo:配置(op_user_id,op_user_passwd)
16             reqHandler.setParameter("op_user_passwd", MD5Util.GetMD5("111111", "GBK"));
17              */
18 
19             return TenpayHelper.Refund(WeiXinConst.PartnerId, WeiXinConst.PartnerKey,
20                orderNo, transactionId, totalFee, refundNo, refundFee,
21                WeiXinConst.CertPath, WeiXinConst.CertPwd);
22         }

 

TenpayHelper.Refund()方法是对V2官方demo再次封装的,相关方法做了一点修改:

 1     /// <summary>
 2     /// V2 接口 退款帮助类
 3     /// </summary>
 4     public class TenpayHelper
 5     {
 6         /// <summary>
 7         /// 申请退款
 8         /// </summary>
 9         /// <param name="partnerId">商户号</param>
10         /// <param name="partnerKey">财付通密钥</param>
11         /// <param name="orderNo">商户订单号</param>
12         /// <param name="transanctionId">微信订单号</param>
13         /// <param name="totalFee">总金额(单位:分)</param>
14         /// <param name="refundNo">退款单号</param>
15         /// <param name="refundFee">退款金额(单位:分)</param>
16         /// <param name="Context">MVC页面请求上下文对象</param>
17         /// <returns></returns>
18         public static bool Refund(string partnerId, string partnerKey, string orderNo,
19             string transanctionId, string totalFee, string refundNo, string refundFee,
20             string certPath, string certPwd)
21         {
22             //商户号
23             string partner = partnerId;
24             //创建请求对象
25             RequestHandler reqHandler = new RequestHandler();
26             //通信对象
27             TenpayHttpClient httpClient = new TenpayHttpClient();
28             //应答对象
29             ClientResponseHandler resHandler = new ClientResponseHandler();
30

37             reqHandler.setGateUrl("https://mch.tenpay.com/refundapi/gateway/refund.xml");
38 
39             reqHandler.setParameter("partner", partner);
40             //out_trade_no和transaction_id至少一个必填,同时存在时transaction_id优先
41             if (string.IsNullOrEmpty(transanctionId))
42             {
43                 if (string.IsNullOrEmpty(orderNo))
44                     throw new Exception("订单号不能为空!");
45 
46                 reqHandler.setParameter("out_trade_no", orderNo);

57             reqHandler.setParameter("op_user_passwd", MD5Util.GetMD5("111111", "GBK"));
58             reqHandler.setParameter("service_version", "1.1");
59 
60             string requestUrl = reqHandler.getRequestURL();
61             httpClient.setCertInfo(certPath, certPwd);
62             //设置请求内容
63             httpClient.setReqContent(requestUrl);
64             //设置超时
65             httpClient.setTimeOut(10);
66 
67             string rescontent = "";
