Csharp/C#教程：c#动态调用Webservice的两种方法实例分享

方法一：
代码如下:
Hashtableht=newHashtable();
           ht.Add(“a”,”testhelloworld”);
           XmlDocumentxx=WebServicesHelper.QuerySoapWebService(“//www.jb51.net/elab_mgmt/WorkflowSchemeTaskSerivce.asmx”,”ATesting”,ht);
           stringss=xx.OuterXml;

代码如下:
///<summary>
       ///通用WebService调用(Soap),参数Pars为String类型的参数名、参数值
       ///</summary>
       publicstaticXmlDocumentQuerySoapWebService(StringURL,StringMethodName,HashtablePars)
       {
           if(_xmlNamespaces.ContainsKey(URL))
           {
               returnQuerySoapWebService(URL,MethodName,Pars,_xmlNamespaces[URL].ToString());
           }
           else
           {
               returnQuerySoapWebService(URL,MethodName,Pars,GetNamespace(URL));
           }
       }

代码如下:
privatestaticXmlDocumentQuerySoapWebService(StringURL,StringMethodName,HashtablePars,stringXmlNs)
       {
           _xmlNamespaces[URL]=XmlNs;//加入缓存，提高效率
           HttpWebRequestrequest=(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);
           XmlDocumentdoc=newXmlDocument(),doc2=newXmlDocument();
           doc=ReadXmlResponse(request.GetResponse());

           XmlNamespaceManagermgr=newXmlNamespaceManager(doc.NameTable);
           mgr.AddNamespace(“soap”,”https://schemas.xmlsoap.org/soap/envelope/”);
           StringRetXml=doc.SelectSingleNode(“//soap:Body/*/*”,mgr).InnerXml;
           doc2.LoadXml(“<root>”+RetXml+”</root>”);
           AddDelaration(doc2);
           returndoc2;
       }

代码如下:
privatestaticstringGetNamespace(StringURL)
       {
           HttpWebRequestrequest=(HttpWebRequest)WebRequest.Create(URL+”?WSDL”);
           SetWebRequest(request);
           WebResponseresponse=request.GetResponse();
           StreamReadersr=newStreamReader(response.GetResponseStream(),Encoding.UTF8);
           XmlDocumentdoc=newXmlDocument();
           doc.LoadXml(sr.ReadToEnd());
           sr.Close();
           returndoc.SelectSingleNode(“//@targetNamespace”).Value;
       }

方法二：

通过SOAPUI直接取URL
代码如下:
stringpostData2=”<soapenv:Envelopexmlns:soapenv=”https://schemas.xmlsoap.org/soap/envelope/”xmlns:tem=”https://tempuri.org/”><soapenv:Header/><soapenv:Body><tem:ATesting><!–Optional:–><tem:a>?</tem:a></tem:ATesting></soapenv:Body></soapenv:Envelope>”;
           HttpHelper.GetResponseFormUrlAsync(“https://www.xxx.com/testingservices.asmx?wsdl”,postData2,”text/xml”,true,newAsyncCallback(responseCallback));

代码如下:
}
       staticvoidresponseCallback(IAsyncResultar)
       {
           HttpWebRequestreq=ar.AsyncStateasHttpWebRequest;
           if(req==null)
               return;
           try
           {
               HttpWebResponseresponse=req.EndGetResponse(ar)asHttpWebResponse;
               if(response.StatusCode!=HttpStatusCode.OK)
               {
                   response.Close();
                   LogHelper.Error(“定时任务”,”异步执行失败,”+req.RequestUri.ToString()+”rnResponse状态代码为rn”+response.StatusCode.ToString());
                   return;
               }
               StreamresponseStream=response.GetResponseStream();
               StreamReaderreader=newStreamReader(responseStream,Encoding.UTF8);
               stringResponseStr=reader.ReadToEnd();
               responseStream.Close();
               LogHelper.Warn(“定时任务”,req.RequestUri.ToString()+”rn”+ResponseStr);
           }
           catch(Exceptione)
           {
               LogHelper.Fatal(“定时任务”,req.RequestUri.ToString()+”rn执行失败”,e);
           }
       }
