C# 调用SAP WebService接口（SoapUI Postman）

1.使用SoapUI 解析wsdl

SAP wsdl地址发放在浏览器中是需要输入用户名密码进行认证的

将wsdl地址放到SoapUI进行解析
输入用户名密码

左边就是请求的XML格式，右边是接口返回内容，点击运行就可以看到结果

2.使用Postman调用

Request1的地址就是我们需要调用的地址（这里提供的域名和wsdl 的域名不一致，需要换成wsdl的域名，SAP是用了跳转网址的），将soapui左边的XML复制到postman中，接口需要在header中加入SOAPAction，SOAPAction在soapui工具的Raw中，如图：

Content-Type为text/xml;charset=UTF-8；Headers中一定要加入SOAPAction；Body中选择Raw Xml进行请求，再加上认证Basic Auth；就可以请求成功了

3.使用C#代码进行调用

publicstaticvoidRequestSAP(string url,int timeout,string xmlData,string userName,string password,outstring statusCode,outstring resultContent){
            statusCode ="400";
            resultContent ="";try{byte[] bytes = Encoding.UTF8.GetBytes(xmlData);//Basic Authbyte[] byteUser = Encoding.Default.GetBytes(userName +":"+ password);string Authorization = Convert.ToBase64String(byteUser);HttpWebRequest request = HttpWebRequest.CreateHttp(url);//避免远程连接证书无效问题
                ServicePointManager.ServerCertificateValidationCallback =(s, certificate, chain, errs)=>true;
                request.Method ="POST";
                request.Timeout = timeout;
                request.ContentType ="text/xml;charset=UTF-8";
                request.ContentLength = bytes.Length;
                request.Headers.Add("Authorization","Basic "+ Authorization);//根据soapui中的SOAPAction 进行赋值
                request.Headers.Add("SOAPAction","SOAPAction");Stream requestStream = request.GetRequestStream();
                requestStream.Write(bytes,0, bytes.Length);HttpWebResponse response = request.GetResponse()asHttpWebResponse;
                statusCode = response.StatusCode.ToString("d");Stream responseStream = response.GetResponseStream();StreamReader sr =newStreamReader(responseStream, Encoding.UTF8);
                resultContent = sr.ReadToEnd();
                sr.Dispose();
                requestStream.Close();
                responseStream.Close();
                response.Dispose();}catch(Exception ex){
                statusCode ="400";
                resultContent = ex.Message;}}
