WSDL and SOAP header

Viktor, This is good feedback; thank you for passing it along! Can you please shed some more light on your development environment so that we can best understand your requirements?

• What version of .NET are you using?
• Are you using WCF?
• Are you using any added products to orchestrate your web services consumption - ie Amberpoint or something of that nature?
• ...

Thank you, Brent

Brent,

We use .NET 3.5 and Visual Studio 2008. We'd like to use WCF, but we have 2 problems with it. (WSDL is probably fine)

First of all, we have a simple solution to use old fashion Web service reference with WSE 3.0 (Web Services Extensions). Code:

using Microsoft.Web.Services3.Security.Tokens;
...
GenesisIntegrationWs giws = new GenesisIntegrationWs();
UsernameToken usernameToken = new UsernameToken("login", "password", PasswordOption.SendHashed);
giws.RequestSoapContext.Security.Tokens.Add(usernameToken);

And it almost works (server returns that it can't validate user credentials, probably wrong user or password), but we traced sent messages, they have security header as required (I suppose we'll discuss this with the support).

But we'd like to use WCF and the problems are:
1. We can't find how correctly set security info (UsernameToken)
2. When trying to run test without security header (just to try), program throws an exception:
RPC Message in operation ExportGetSegmentedDataRequest has an invalid body name Export.GetSegmentedDataRequest. It must be ExportGetSegmentedDataRequest
Shortly speaking, looks like Web service proxy class, which was created by adding Service reference with Visual Studio don't like period in method or other names. Looks like it has created incorrect wrapper for class for Export.GetSegmentedDataRequest message (commenting it in code, the same exception is thrown for any else message with period in name).

Do you have samples of WCF client for your web services?

In general forum using WSE3: http://developer.omniture.com/node/265 Would be great to have someone discovered WCF option.

With the old Omniture API, I was using C# code similar to your code snippet to authenticate. It seems I can't do that any more with the new Genesis API. After instantiating a GenesisIntegrationWebService object, it does not have a RequestSoapContext method. I have added a reference to Microsoft.Web.Services3, included the using statement "Microsoft.Web.Services3.Security.Tokens". I am using .NET 2.0 (C#) and am building a Console App. Any ideas on how I can get the authentication working? Thanks! -Ned

If you have updated Web reference to the new WSDL, don't forget to change web service proxy class inheritance from System.Web.Services.Protocols.SoapHttpClientProtocol to Microsoft.Web.Services3.WebServicesClientProtocol in Reference.cs file (find it within Web reference folder) and check service endpoint address in app.config Add WSDL as a Web Reference, not Service Reference (if you did), since it is a WCF platform, which can't use WSE3. Currently I have no idea how to use WCF with Omniture Partner API, all I know, we have to use WS2007HttpBinding, which supports OASIS spec, but I have not found how to use hashed password for UsernameToken.

I am trying to consume the Web Service in a .net envrionment. * Downloaded the WSDL from the site * Created the Proxy class using WSDL tool of .net * Included that Proxy class in my windows application * Tried invoking the method 'PermissionsAuthenticate' and i get 'System.Web.Services.Protocols.SoapException: Could not retrieve authentication credentials from SOAP header at System.Web.Services.Protocols.SoapHttpClientProtocol.ReadResponse(SoapClientMessage message, WebResponse response, Stream responseStream, Boolean asyncCall) at System.Web.Services.Protocols.SoapHttpClientProtocol.Invoke(String methodName, Object[] parameters) at OmnitureWebService.PermissionsAuthenticate(String login, String password) in WindowsFormsApplication1\WindowsFormsApplication1\OmnitureWebService.cs:line 3179' I am using .net 3.5, could you please help in consuming this web service in .net Regards Satheesh

I am trying to set up the same using VB.Net. I have done as you have but I get another error: 'The web server responded with error 407. Proxy Authentication Required' Have ou encountered this?

To all on this thread... I think that maybe the draft documentation discussing how to consume the partner APIs through C# will help you. You can find it here: http://developer.omniture.com/node/825

Downloaded the documentation - but still getting no where. There surely must be someone who knows how to consume Omniture Web Services with VB.NET. I have managed to get to the point where I am now getting the message 'Cannot Connect to the Remote Server'. Here is an outline of how I have set this up in VB.NET - I useds a Windows Application for simplicity. 1. Downloaded the wsdl 2. Created a proxy class in my VB.NET app Here is the code: Public Class Form1 Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click 'Variables Dim o As New OmnitureWebService Dim nounce As String '================================================================================ 'Generate a Digest password '=============================================================================== 'Create a random string for the nouce Dim AlphaNumericString As String = Guid.NewGuid.ToString 'Guid returns radom alphanumeric with dashes - so remove them AlphaNumericString = AlphaNumericString.Replace("-", "") 'Create the nouce nounce = AlphaNumericString 'Generate a string representation of the current time in format YYYY-MM-DD Dim currentdate As Date = Now Dim year As String = currentdate.ToString("yyyy") Dim month As String = currentdate.ToString("MM") Dim day As String = currentdate.ToString("dd") Dim hour As String = currentdate.ToString("HH") Dim min As String = currentdate.ToString("mm") Dim secs As String = currentdate.ToString("ss") Dim requestDate As String requestDate = year + "-" + month + "-" + day + " " + hour + ":" + min + ":" + secs 'Include Shared Secret Dim sharedSecret As String = "secret entered here" 'Concatenate Nouce Date and Shared Secret Dim unhashedpassword As New System.Text.StringBuilder() unhashedpassword.Append(nounce) unhashedpassword.Append(requestDate) unhashedpassword.Append(sharedSecret) 'Create an SHA1 hash of concatenated string Dim sha1Hash As String = getSHA1Hash(unhashedpassword.ToString) 'Encode the SHA1 in base64 Dim encoding As New System.Text.ASCIIEncoding() Dim mByte As Byte() mByte = encoding.GetBytes(sha1Hash) 'Get Digest Password Dim password As String = ToBase64(mByte) '=== End generating Digest Password '==== PROXY AUTHENTICATION ================================================================= Dim proxy As New System.Net.WebProxy proxy.Credentials = New System.Net.NetworkCredential("Username", "password", "Domain") o.Proxy = proxy Try 'Test for URL - This Shows "https://api2.omniture.com/admin/1.2/" when clicked MsgBox(o.Url) 'Try to connect Dim b As Boolean = o.PermissionsAuthenticate("", password) MsgBox(b.ToString) Catch ex As Exception MsgBox(ex.Message) End Try End Sub Function getSHA1Hash(ByVal strToHash As String) As String Dim sha1Obj As New Security.Cryptography.SHA1CryptoServiceProvider Dim bytesToHash() As Byte = System.Text.Encoding.ASCII.GetBytes(strToHash) bytesToHash = sha1Obj.ComputeHash(bytesToHash) Dim strResult As String = "" For Each b As Byte In bytesToHash strResult += b.ToString("x2") Next Return strResult End Function Public Function ToBase64(ByVal data() As Byte) As String If data Is Nothing Then Throw New ArgumentNullException("data") Return Convert.ToBase64String(data) End Function End Class The error I get is 'Unable to Connect to Remote Server - any ideas what could be wrong with this code

I am in the same situation of 'adform_viktor'. It get exactly the same error but with different function. Until i close this, i will not be able to proceed further on passing the username and password.
