C#代码如下

1. 数据结构

    public class RequestInfo
       {
          /// 
   
          /// 商户秘钥
          /// 
           public string paykey { get; set; }
           /// 
   
           /// 请求地址
           /// 
           public string req_uri { get; set; }
           /// 
   
           /// 商户订单号
           /// 
           public string out_trade_no { get; set; }
           /// 
   
           /// 商品描述
           /// 
           public string body { get; set; }
           /// 
   
           /// 总金额
           /// 
           public int total_fee { get; set; }
           /// 
   
           /// 订单生成时间
           /// 
           public string time_start { get; set; }
           /// 
   
           /// 商户号
           /// 
           public string mch_id { get; set; }
           /// 
   
           /// 通知回调地址
           /// 
           public string notify_url { get; set; }
           /// 
   
           /// 签名方式
           /// 
           public string sign_type { get; set; }
       }
   

   　　2.发起请求

     public void SendPay(RequestInfo resInfo)
               {
                   var dic = new Dictionary
                   {
                       {"id",resInfo.mch_id},//个人支付Id
                       {"pay_id", resInfo.out_trade_no},//唯一标识，可以是用户ID,用户名,session_id(),订单ID,ip 付款后返回
                       {"type","1"},//1支付宝支付 3微信支付 2QQ钱包
                       {"price",price.ToString()},//总金额
                       {"notify_url",resInfo.notify_url},//通知回调地址，商户需改为自己的，且保证外网能POST发送数据请求成功.
                       {"return_url",""},//跳转地址
                       {"page","4"}
                   };
                   var query = GetOtherSignString(dic, resInfo.paykey);
                   Encoding en = Encoding.GetEncoding("UTF-8");
                   HttpWebResponse response = CreatePostHttpResponse(resInfo.req_uri, query, en);
                   Stream stream = response.GetResponseStream();   //获取响应的字符串流
                   StreamReader sr = new StreamReader(stream); //创建一个stream读取流
                   string html = sr.ReadToEnd();   //从头读到尾，放到字符串html
                   JavaScriptSerializer serializer = new JavaScriptSerializer();
                   Dictionary json = (Dictionary)serializer.DeserializeObject(html);
                   string status = "";
                   string code_url = "";
                   string code_img_url = "";
                   logger.Error(json);
                   foreach (var item in json)
                   {
                       if (item.Key == "status")
                       {
                           status = item.Value.ToString();
                       }
                       if (item.Key == "qrcode")
                       {
                           code_img_url = item.Value.ToString();
                       }
                       if (item.Key == "qr")
                       {
                           code_url = item.Value.ToString();
                       }
                   }
   
                   //发起支付
                   if (status != "" && status =="0")
                   {
                       imgCpdehUrl = code_img_url;
                       errmsg = "码支付本地订单(" + HttpUtility.HtmlEncode(tradeno) + ")处理成功.";
                       logger.Error(errmsg);
                   }
                   else
                   {
                       errmsg = "JSAPI码支付发起支付(" + HttpUtility.HtmlEncode(tradeno) + ")发生错误.";
                       logger.Error(errmsg);
                       return Content("" + "抱歉，支付订单处理失败" + "
   " + errmsg + "
   ");
                   }
               }
   

   　　3.扩展方法：处理请求参数

     public static string GetOtherSignString(Dictionary dic, string key)
           {
               var newDic = dic.Where(p => p.Key != "sign").OrderBy(p => p.Key);
               string sign = "";
               string urls = "";
               foreach (var item in newDic)
               {
                   if (item.Value == "" || item.Key == "sign") continue;//跳过不需要的参数名
                   //追加&拼接URL
                   if (sign != "")
                   {
                       sign += "&";
                       urls += "&";
                   }
                   sign += item.Key + "=" + item.Value;
                   urls += item.Key + "=" + HttpUtility.UrlEncode(item.Value);
               }
   
               sign = System.Web.Security.FormsAuthentication.HashPasswordForStoringInConfigFile(sign += key, "MD5");//md5加密
               return urls + "&sign=" + sign;
           }
   

   　　4.通知回调处理

    private static bool doNotifyProcess_shpayAliMA(string appid, string orderid, string srContent, out string resultValue, StringBuilder errorMsgs)
           {
               resultValue = "";
               string _msg;
               var str = srContent.Split(‘&‘);//分割回调字符串
               string status = "";
               string out_trade_no = "";
               string price = "";
               foreach (var item in str)
               {
                   if (item.IndexOf("status") > -1)
                   {
                       status = item.Split(‘=‘)[1];//订单状态
                   }
                   if (item.IndexOf("pay_id") > -1)
                   {
                       out_trade_no = item.Split(‘=‘)[1];//订单号
                   }
                   if (item.IndexOf("money") > -1)
                   {
                       price = item.Split(‘=‘)[1];//价格
                   }
               }
   
               if (status != "" && Convert.ToInt32(status) == 0)
               {
                   // 充值支付核心处理（回调信息写入 +  充值处理）
                   if (ServiceHelper.WriteAndFillOrderPay_ShAliMA(out_trade_no,decimal.Parse(price), "Post", out _msg))
                   {
                       // 商户成功接收到支付结果通知之后，返回http包体数据为SUCCESS。若返回数据非SUCCESS，则视为失败
                       resultValue = _SH_SUCCESS;
                       errorMsgs.Append("[MA成功](" + out_trade_no + ")" + resultValue);
                       return true;
                   }
                   else
                   {
                       // 回写订单发货失败
                       resultValue = _SH_ERROR;
                       errorMsgs.Append("[MA支付失败](" + out_trade_no + ")" + resultValue + _msg);
                   }
               }
               else
               {
                   // 签名和数据解析失败
                   resultValue = _SH_ERROR;
                   errorMsgs.Append("[MA成功](" + out_trade_no + ")");
   
               }
               return false;
           }
