C#微信开发之旅(十一)：V2发货接口

用户支付完成后，V2版本微信支付需要调用发货接口，否则微信会告警并且用户也可以进行维权，总之会有灰常多的事情：

        public void DeliverNotify()
        {
            string openId = string.Empty; //买家openid
            string transactionId = string.Empty;//微信交易单号
            string orderNo = string.Empty;//我们自己的订单号，文档中的out_trade_no


            WxPayModel model = WxPayModel.Create();
            string postData = model.CreateDeliverNotifyPackage(openId, transactionId, orderNo);
            WeiXinHelper.DeliverNotify(postData);
        }

下面是创建发货通知json的方法：

        /// <summary>
        /// 创建发货成功 Package (已测试通过)
        /// </summary>
        /// <returns></returns>
        public string CreateDeliverNotifyPackage(string openId, string transId, string out_trade_no)
        {
            Dictionary<string, string> nativeObj = new Dictionary<string, string>();

            nativeObj.Add("appid", AppId);
            nativeObj.Add("openid", openId);
            nativeObj.Add("transid", transId);
            nativeObj.Add("out_trade_no", out_trade_no);
            nativeObj.Add("deliver_timestamp", ((DateTime.Now.ToUniversalTime().Ticks - 621355968000000000) / 10000000).ToString());
            nativeObj.Add("deliver_status", "1");
            nativeObj.Add("deliver_msg", "ok");
            nativeObj.Add("app_signature", GetBizSign(nativeObj));
            nativeObj.Add("sign_method", "sha1");

            var entries = nativeObj.Select(d => string.Format("\"{0}\": \"{1}\"", d.Key, d.Value));

            return "{" + string.Join(",", entries.ToArray()) + "}";
        }
