方式一：

Hashtable ht = new Hashtable();            ht.Add("a", "testhelloworld");            XmlDocument xx = WebServicesHelper.QuerySoapWebService("http://e-learning.huawei.com/elab_mgmt/WorkflowSchemeTaskSerivce.asmx", "ATesting", ht);            string ss = xx.OuterXml;

 

/// 
        /// 通用WebService调用(Soap),参数Pars为String类型的参数名、参数值        /// 
        public static XmlDocument QuerySoapWebService(String URL, String MethodName, Hashtable Pars)        {            if (_xmlNamespaces.ContainsKey(URL))            {                return QuerySoapWebService(URL, MethodName, Pars, _xmlNamespaces[URL].ToString());            }            else            {                return QuerySoapWebService(URL, MethodName, Pars, GetNamespace(URL));            }        }

 

private static XmlDocument QuerySoapWebService(String URL, String MethodName, Hashtable Pars, string XmlNs)        {            _xmlNamespaces[URL] = XmlNs;//加入缓存，提高效率            HttpWebRequest request = (HttpWebRequest)HttpWebRequest.Create(URL);            request.Method = "POST";            request.ContentType = "text/xml; charset=utf-8";            request.Headers.Add("SOAPAction", "\"" + XmlNs + (XmlNs.EndsWith("/") ? "" : "/") + MethodName + "\"");            SetWebRequest(request);            byte[] data = EncodeParsToSoap(Pars, XmlNs, MethodName);            WriteRequestData(request, data);            XmlDocument doc = new XmlDocument(), doc2 = new XmlDocument();            doc = ReadXmlResponse(request.GetResponse());            XmlNamespaceManager mgr = new XmlNamespaceManager(doc.NameTable);            mgr.AddNamespace("soap", "http://schemas.xmlsoap.org/soap/envelope/");            String RetXml = doc.SelectSingleNode("//soap:Body/*/*", mgr).InnerXml;            doc2.LoadXml("
     
      " + RetXml + "
     ");            AddDelaration(doc2);            return doc2;        }

private static string GetNamespace(String URL)        {            HttpWebRequest request = (HttpWebRequest)WebRequest.Create(URL + "?WSDL");            SetWebRequest(request);            WebResponse response = request.GetResponse();            StreamReader sr = new StreamReader(response.GetResponseStream(), Encoding.UTF8);            XmlDocument doc = new XmlDocument();            doc.LoadXml(sr.ReadToEnd());            sr.Close();            return doc.SelectSingleNode("//@targetNamespace").Value;        }

 

 

方式二：

通过SOAPUI直接取URL

string postData2="
     
      
      
       
        
        
         ?
        
       
      
     ";            HttpHelper.GetResponseFormUrlAsync("http://www.xxx.com/testingservices.asmx?wsdl", postData2, "text/xml", true, new AsyncCallback(responseCallback));

}        static void responseCallback(IAsyncResult ar)        {            HttpWebRequest req = ar.AsyncState as HttpWebRequest;            if (req == null)                return;            try            {                HttpWebResponse response = req.EndGetResponse(ar) as HttpWebResponse;                if (response.StatusCode != HttpStatusCode.OK)                {                    response.Close();                    LogHelper.Error("定时任务", "异步执行失败," + req.RequestUri.ToString() + "\r\nResponse状态代码为\r\n" + response.StatusCode.ToString());                    return;                }                Stream responseStream = response.GetResponseStream();                StreamReader reader = new StreamReader(responseStream, Encoding.UTF8);                string ResponseStr = reader.ReadToEnd();                responseStream.Close();                LogHelper.Warn("定时任务", req.RequestUri.ToString() + "\r\n" + ResponseStr);            }            catch (Exception e)            {                LogHelper.Fatal("定时任务", req.RequestUri.ToString() + "\r\n执行失败", e);            }        }
