How to add custom Http Header for C# Web Service Client consuming Axis 1.4 Web service

Question

Hello,

I'm trying to write a web service client in c# which the webservice is Java Axis 1.4. Axis service requires the Authorization: Basic Base64EncodedToken header value in the HTTP Headers. I can't find a way to set this header in standart ways of consuming web services in visual studio.net, like normal WSDL generated refernce nor with WSE3.0

I can't use WCF as the project is developed using .net 2.0.

Is there any way to do this ?

Thanks, Umut

See Building Secure ASP.NET Applications: Authentication, Authorization, and Secure Communication and search on "Using specific credentials". Also see the MSDN docs for the CredentialCache Class.

Answer 2

If you want to send a custom HTTP Header (not a SOAP Header) then you need to use the HttpWebRequest class the code would look like:

HttpWebRequest webRequest = (HttpWebRequest)WebRequest.Create(url);
webRequest.Headers.Add("Authorization", token);

You cannot add HTTP headers using the visual studio generated proxy, which can be a real pain.

This is what i was looking for.

Are we talking WCF here? I had issues where the service calls were not adding the http authorization headers, wrapping any calls into this statement fixed my issue.

using (OperationContextScope scope = new OperationContextScope(RefundClient.InnerChannel))
          {
                    var httpRequestProperty = new HttpRequestMessageProperty();
                    httpRequestProperty.Headers[System.Net.HttpRequestHeader.Authorization] = "Basic " +
                    Convert.ToBase64String(Encoding.ASCII.GetBytes(RefundClient.ClientCredentials.UserName.UserName + ":" +
                    RefundClient.ClientCredentials.UserName.Password));
                    OperationContext.Current.OutgoingMessageProperties[HttpRequestMessageProperty.Name] = httpRequestProperty;

                    PaymentResponse = RefundClient.Payment(PaymentRequest);

                }

This was running SOAP calls to IBM ESB via .NET with basic auth over http or https.

hope this helps someone because i had massive issues finding a solution online.

It seems the original author has found their solution, but for anyone else who gets here looking to add actual custom headers, if you have access to mod the generated Protocol code you can override GetWebRequest:

    protected override System.Net.WebRequest GetWebRequest(Uri uri)
    {
        System.Net.WebRequest request = base.GetWebRequest(uri);
        request.Headers.Add("myheader", "myheader_value");
        return request;
    }

makes sure you remove the DebuggerStepThroughAttribute attribute if you want to step into it.

I find this code and is resolve my problem.

http://arcware.net/setting-http-header-authorization-for-web-services/

protected override WebRequest GetWebRequest(Uri uri) { // Assuming authValue is set from somewhere, such as the config file HttpWebRequest request = (HttpWebRequest)base.GetWebRequest(uri); request.Headers.Add("Authorization", string.Format("Basic {0}", authValue)); return request; }
