C#代码如下

 

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

      2.发起请求

      public void SendPay(RequestInfo resInfo)
                {
                    var dic = new Dictionary<string, string>
                    {
                        {"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<string, object> json = (Dictionary<string, object>)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("<span style=‘color:#FF0000;font-size:20px‘>" + "抱歉,支付订单处理失败" + "</span><p>" + errmsg + "</p>");
                    }
                }
    

      3.扩展方法:处理请求参数

      public static string GetOtherSignString(Dictionary<string, string> 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;
            }
