c#（POST）动态对接SAP WebService接口

1、通过软件工具SoapUI获取请求体和响应体

第二步c#调用

 public XmlDocument QueryPostWebService(String URL, String MethodName, string inputPars, string userName, string passWord, string domain)
        {
            HttpWebRequest request = (HttpWebRequest)HttpWebRequest.Create(URL);
            request.Method = "POST";
            request.ContentType = "text/xml; charset=utf-8";
            request.Headers.Add("Accept-Language", "zh;");//设置SAP登录语言为中文
            SetWebRequest(request, userName, passWord, domain);
            byte[] data = Encoding.UTF8.GetBytes(inputPars);
            WriteRequestData(request, data);
            return ReadXmlResponse(request.GetResponse());
        }

        private void SetWebRequest(HttpWebRequest request, string userName, string passWord, string domain = "saps4demo.sz-sunway.com")
        {
            NetworkCredential cred = new NetworkCredential(userName, passWord);
            request.Credentials = cred;
            request.Timeout = 120000;
        }

        private void WriteRequestData(HttpWebRequest request, byte[] data)
        {
            request.ContentLength = data.Length;
            Stream writer = request.GetRequestStream();
            writer.Write(data, 0, data.Length);
            writer.Close();
        }

        private XmlDocument ReadXmlResponse(WebResponse response)
        {
            StreamReader sr = new StreamReader(response.GetResponseStream(), Encoding.UTF8);
            String retXml = sr.ReadToEnd();
            sr.Close();
            XmlDocument doc = new XmlDocument();
            doc.LoadXml(retXml);
            return doc;
        }

注意：

SOAP V 1.1 --->参数使用：“soapenv:” 命名空间“http://schemas.xmlsoap.org/soap/envelope/”　　request.ContentType="text/xml; charset=utf-8"

SOAP V 1.2 --->参数使用：“soap:” 命名空间“http://www.w3.org/2003/05/soap-envelope”　　　　 request.ContentType="application/soap+xml; charset=utf-8"
