应用WSDK － 实践Web Services的数字签名(下)

cd\tmp

wsdl /l:cs /out:SignSOAPWebServices.cs /n:SignSOAPSvc /urlkey:SecurityURL http://localhost/Myproject/WSDK/SignSOAPUsingName/SignSOAPusingName.asmx?WSDK

加入Microsoft.WebServices.DLL 引用和下面的代码

using Microsoft.Web.Services.Security ;

using Microsoft.Web.Services;

并将 System.Web.Services.Protocols.SoapHttpClientProtocol 替换为

 Microsoft.Web.Services.WebServicesClientProtocol

private void btnCallWebservice_Click(object sender, System.EventArgs e)

{

     try

     {

         string username = Environment.UserName ;

         byte[] passwordBytes = System.Text.Encoding.UTF8.GetBytes( username ) ;

         Array.Reverse( passwordBytes ) ;

         string passwordEquivalent = Convert.ToBase64String( passwordBytes ) ;

         UsernameToken userToken = new UsernameToken( username, passwordEquivalent, PasswordOption.SendHashed ) ;

         SignSOAPSvc.SignSOAPWebServices  Svc = new SignSOAPSvc.SignSOAPWebServices() ;

         Svc.RequestSoapContext.Timestamp.Ttl = 60000 ;

         Svc.RequestSoapContext.Security.Tokens.Add( userToken ) ;

         Svc.RequestSoapContext.Security.Elements.Add( new Signature( userToken ) ) ;

         lblCallRet.Text = Svc.HelloWorld() ;

     }

     catch ( System.Web.Services.Protocols.SoapException soapex )

     {

         MessageBox.Show ( soapex.ToString() ) ;

     }

     catch ( Exception ex )

     {

         MessageBox.Show( ex.ToString() ) ;

     }

}
