问题描述

我想用HTTPwebrequest来调用webservice。



我试过这个方法吧不工作，可以帮助我解决这个问题。



先谢谢。



public static string fnSendandReceiveurlencode（string Request，string WebServiceURL）

{

string rawResponse;

HttpWebRequest webreq =（HttpWebRequest）WebRequest.Create（WebServiceURL）;

webreq.ContentType =text / xml; charset = utf-8;

//webreq.Accept =text / xml;

webreq.Headers.Clear（）;

webreq.Method =POST;

byte [] bytes = Encoding.UTF8.GetBytes（Request.ToString（））;

Encoding encode = Encoding.GetEncoding（utf-8）;

webreq.ContentLength = bytes.Length;

HttpWebResponse webres = null;

webres =（HttpWebResponse）webreq.GetResponse（）;

流阅读器= null;

reader = webres.GetResponseStream（）;

StreamReader sreader = new StreamReader（reader，encode，true）;

rawResponse = sreader.ReadToEnd（）;

返回rawResponse;

}

推荐答案

试试这个。

Try this.

HttpWebRequest webreq = (HttpWebRequest)WebRequest.Create(WebServiceURL);

        webreq.Method = "POST";     
       webreq.ContentType = "text/xml";

 var encoding = new UTF8Encoding();
 var bytes = Encoding.GetEncoding("iso-8859-1").GetBytes(Request.ToString());
 webreq.ContentLength = bytes.Length;

            using (var writeStream = webreq.GetRequestStream())
            {
                writeStream.Write(bytes, 0, bytes.Length);
            }

            using (var response = (HttpWebResponse)webreq.GetResponse())
            {

                var responseValue = string.Empty;

                if(response.StatusCode == HttpStatusCode.OK)
                {
                   
                     using (var responseStream = response.GetResponseStream())
                     {
                       if (responseStream != null)
                       using (var reader = new StreamReader(responseStream))
                       {
                           responseValue = reader.ReadToEnd();
                       }
                     }
               }
            }
