调用webservice的几种方法: 方法一:添加web引用(简单/方便 局限客户端是.net) 方法二:Post xml(本文重点讲述) 方法三:使用微软MSXML2组件(好像在window server2008上就不支持) 方法四:在页面上添加form post到服务端 //创建HttpWebRequest 实例,使用WebRequest.Create HttpWebRequest webRequest = (HttpWebRequest)WebRequest.Create("服务地址"); //发送请求 webRequest.Method = "POST"; //编码 webRequest.ContentType = "text/xml"; string soap = "<?xml version=\"1.0\" encoding=\"utf-8\"?>"; soap += "<soap:Envelope xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\" xmlns:xsd=\"http://www.w3.org/2001/XMLSchema\" xmlns:soap=\"http://schemas.xmlsoap.org/soap/envelope/\">"; soap += " <soap:Header>"; soap += " <SoapHeader xmlns=\"http://www.52taiqiu.com/\">"; soap += " <Login>" + txtUser.Text + "</Login>"; soap += " <Password>" + txtPwd.Text + "</Password>"; soap += " </SoapHeader>"; soap += " </soap:Header>"; soap += "<soap:Body>"; soap += " <Request xmlns=\"http://www.52taiqiu.com/\">"; soap += " <requestXml><![CDATA[" + txtRequest.Text + "]]></requestXml>"; soap += " </Request>"; soap += "</soap:Body>"; soap += "</soap:Envelope>"; webRequest.Headers["SoapAction"] = "http://www.52taiqiu.com/Request"; //字符转字节 byte[] bytes = Encoding.UTF8.GetBytes(soap); Stream writer = webRequest.GetRequestStream(); writer.Write(bytes, 0, bytes.Length); writer.Flush(); writer.Close(); string result = ""; //返回 HttpWebResponse try { HttpWebResponse hwRes = webRequest.GetResponse() as HttpWebResponse; if (hwRes.StatusCode == System.Net.HttpStatusCode.OK) {//是否返回成功 Stream rStream = hwRes.GetResponseStream(); //流读取 StreamReader sr = new StreamReader(rStream, Encoding.UTF8); result = sr.ReadToEnd(); sr.Close(); rStream.Close(); } else { result = "连接错误"; } //关闭 hwRes.Close(); txtResponse.Text = result; } catch (System.Net.WebException ex) { String responseFromServer = ex.Message.ToString() + " "; if (ex.Response != null) { using (WebResponse response = ex.Response) { Stream data = response.GetResponseStream(); using (StreamReader reader = new StreamReader(data)) { responseFromServer += reader.ReadToEnd(); } } } txtResponse.Text = responseFromServer; }
