C# Post主动发送Json格式数据、主动接收通知并且返回发送给对方成功或失败

1.Post主动发送Json格式数据

       /// <summary> 
        /// 指定Post地址使用Get 方式获取全部字符串 
        /// </summary> 
        /// <param name="url">请求后台地址</param> 
        /// <param name="content">Post提交数据内容(utf-8编码的)</param> 
        /// <returns>结果</returns> 
        public static string DataPost(string url, string content, HttpResponseBase Response)
        {
            //申明一个容器result接收数据
            string result = "";
            try
            {
                //首先创建一个HttpWebRequest,申明传输方式POST
                HttpWebRequest req = (HttpWebRequest)WebRequest.Create(url);
                req.Method = "POST";
                req.ContentType = "application/json";

                //添加POST参数
                byte[] data = Encoding.UTF8.GetBytes(content);
                req.ContentLength = data.Length;
                using (Stream reqStream = req.GetRequestStream())
                {
                    reqStream.Write(data, 0, data.Length);
                    reqStream.Close();
                }

                //申明一个容器resp接收返回数据
                HttpWebResponse resp = (HttpWebResponse)req.GetResponse();
                Stream stream = resp.GetResponseStream();
                //获取响应内容 
                using (StreamReader reader = new StreamReader(stream, Encoding.UTF8))
                {
                    result = reader.ReadToEnd();
                    var stringstr = "<stream><return_code>SUCCESS</return_code></stream>";
                    Response.Write(stringstr);
                    Response.End();
                }
            }
            catch (Exception ex)
            {
                var stringstr = "<stream><return_code>FAIL</return_code></stream>";
                Response.Write(stringstr);
                Response.End();
               
            }
            return result;
        }

2.主动接收通知并且返回发送给对方成功或失败

public static string GetResult(HttpRequestBase Request, HttpResponseBase Response)
        {
            var xmlData = "";
            try
            {
                if (Request.RequestType == "POST")
                {
                    //接收并读取POST过来的XML文件流
                    StreamReader reader = new StreamReader(Request.InputStream);
                    xmlData = reader.ReadToEnd();

                    var stringstr = "<stream><return_code>SUCCESS</return_code></stream>";
                    Response.Write(stringstr);
                    Response.End();

                }
            }
            catch (Exception ex)
            {
                var stringstr = "<stream><return_code>FAIL</return_code></stream>";
                Response.Write(stringstr);
                Response.End();
            }
            return xmlData;
        }
