C#通过post发送接收数据流

发送数据流方法

        /// <summary>
        /// </summary>
        /// <param name="url">目标url</param>
        /// <param name="strPost">要发送的post字符串</param>
        /// <returns>接收后返回值</returns>
        private string PostXML(string url, string strPost)
        {
            string result = string.Empty;
            //生成文件流
            byte[] buffer = Encoding.UTF8.GetBytes(strPost);
            //向流中写字符串
            StreamWriter mywriter = null;
            //根据url创建请求对象
            HttpWebRequest objrequest = (HttpWebRequest)WebRequest.Create(url);
            //设置发送方式
            objrequest.Method = "POST";
            //提交长度
            objrequest.ContentLength = buffer.Length;
            //发送内容格式
            objrequest.ContentType = "text/xml";
            try
            {
                mywriter = new StreamWriter(objrequest.GetRequestStream());
                mywriter.Write(strPost);
            }
            catch (Exception)
            {
                result = "发送文件流失败！";

            }
            finally
            {
                mywriter.Close();
            }
            //读取服务器返回信息
            HttpWebResponse objresponse = (HttpWebResponse)objrequest.GetResponse();
            using (StreamReader sr = new StreamReader(objresponse.GetResponseStream()))
            {
                result = sr.ReadToEnd();
                sr.Close();
            }
            return result;
        }

调用方法发送

        /// <summary>
        /// 
        /// </summary>
        /// <param name="sender"></param>
        /// <param name="e"></param>
        protected void btnSendC_Click(object sender, EventArgs e)
        {

            //读取xml文件
            string path = Server.MapPath("~/ProjectXML/2017-08-28/2017-08-28(2015A5037).xml");
            string DsmpUrl = "http://10.1.12.4:8080/Default.aspx";
            XmlDocument xd = new XmlDocument();
            xd.Load(path);

            string aaa = xd.InnerXml;

            string bbb = PostXML(DsmpUrl, xd.InnerXml);
            Page.ClientScript.RegisterClientScriptBlock(this.GetType(), "", "alert('" + bbb + "')", true);
        }

接收方代码

        protected void Page_Load(object sender, EventArgs e)
        {
            //if (!IsPostBack)
            //{
            //    Response.Redirect("~/Admin/CreateVoucherXML4.aspx");
            //}

            if (Request.RequestType == "POST")
            {
                //接收并读取POST过来的XML文件流
                StreamReader reader = new StreamReader(Request.InputStream);
                String xmlData = reader.ReadToEnd();
                //把数据重新返回给客户端
                //Response.Write(xmlData);

                Response.Write(DateTime.Now.ToString() + "测试成功！");
                Response.End();
            }
