WebService authentication issue RRS feed

  • Question

  • Hi

    I have been having issues connecting to an internal webservice - 401 Unauthorized.  I get this connecting from PowerShell and from a Project created using Visual Studio.

    For some reason it looks like basic authentication is not being used so adding the following in the Visual Studio Project (Reference.cs created from wsdl file) works:

    public partial class testServiceNoKeepAlive : testService
           protected override System.Net.WebRequest GetWebRequest(Uri uri)
               System.Net.HttpWebRequest request;
               request = (System.Net.HttpWebRequest)base.GetWebRequest(uri);
               request.KeepAlive = false;

               System.Net.NetworkCredential networkCredentials = Credentials.GetCredential(uri, "Basic");

               if (networkCredentials != null)

               { byte[] credentialBuffer = new UTF8Encoding().GetBytes(networkCredentials.UserName + ":" + networkCredentials.Password); request.Headers["Authorization"] = "Basic " + Convert.ToBase64String(credentialBuffer); }


               { throw new ApplicationException("No network credentials"); }

               return request;


    Can something similar be done in PowerShell?

  • Just add a header to the Invoke-WebRequest call.

    help Invoke-WebRequest -Parameter Headers

  • Thanks for the reply.

    The PowerShell functions currently use New-WebServiceProxy:

    $Proxy_test = New-WebServiceProxy -Uri $URI_test -Namespace WebServiceProxy.test

    The request is then built and sent.  I cant see an option for adding headers here.

  • help New-WebServiceProxy -para Credential

  • Using -Credential also does not help.  As i understand it should use basic authentication but for some reason the server is not.  This is why we added the above code into the Visual Studio project which forced it to use basic authentication.

  • Then you cannot use new-webserviceproxy.
