c#动态调用Webservices

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;

 

/// <summary>

        /// 通用WebService调用(Soap),参数Pars为String类型的参数名、参数值

        /// </summary>

        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("<root>" + RetXml + "</root>");

            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="<soapenv:Envelope xmlns:soapenv=\"http://schemas.xmlsoap.org/soap/envelope/\" xmlns:tem=\"http://tempuri.org/\"><soapenv:Header/><soapenv:Body><tem:ATesting><!--Optional:--><tem:a>?</tem:a></tem:ATesting></soapenv:Body></soapenv:Envelope>";

            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);

            }

        }
