    Question How can I consume a webservice that uses WSSE?

    Hey everyone. I've run into a problem that I've been trying to figure out for the last 3 days, and I'm not having any luck at all. I'm hoping someone may be able to help me out on something.

    I am trying to write a C# Winform application that can access a third party's webservice that uses WSSE. I'll try to provide as many details as possible.

    The header for the request needs to be like the following:

    Code:
    <soapenv:Envelope xmlns:efil="http://someurl.com/" xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/">
       <soapenv:Header>
          <wsse:Security xmlns:wsse="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-secext-1.0.xsd" xmlns:wsu="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-utility-1.0.xsd">
             <wsse:UsernameToken wsu:Id="UsernameToken-3">
                <wsse:Username>myusername</wsse:Username>
                <wsse:Password Type="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-username-token-profile-1.0#PasswordText">mypassword</wsse:Password>
                <wsse:Nonce EncodingType="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-soap-message-security-1.0#Base64Binary">Uw0swuaymypUcDTUpJ0i0Q==</wsse:Nonce>
                <wsu:Created>2014-01-22T15:48:32.809Z</wsu:Created>
             </wsse:UsernameToken>
          </wsse:Security>
       </soapenv:Header>
       <soapenv:Body>
          <efil:listStuff/>
       </soapenv:Body>
    </soapenv:Envelope>
    I can use the above header (minus the Nonce) in an app called SoapUI and call a method (listStuff) that will return data. However, whenever I try to do so in code, I'm not getting any results. This is what I have tried:

    1. Added a Service Reference to the webservice (https://url.com/Foo?wsdl).
    2. Added a namespace to reference this:
    Code:
    using Svc = testProject.ServiceReference1;
    3. On a button click event, I then tried to call a method by create a client, setting the username/password, but I am not getting any results:
    Code:
    Svc.CreateInterfaceClient client = new Svc.CreateInterfaceClient();
    client.ClientCredentials.UserName.UserName = "username";
    client.ClientCredentials.UserName.Password = "password";
    
    client.Open();
     
    Svc.stuff[] myStuff = client.listStuff();
    
    client.Close();
    I'm not getting any exceptions being thrown, but myStuff is empty (it should contain several hundred "stuff" objects).

    I haven't had to work with webservices before, and I'm sure it's something that I'm just doing wrong. I haven't had any luck finding any examples online that I can go by to figure this out.

    Thanks in advance!

    If there is no API, then you might be out of luck. If it's your service, you know how to call it.

    Re: How can I consume a webservice that uses WSSE?

    Unfortunately, the only thing the third party gave me was a document with a list of methods - but not examples at all of how to call any of their methods. They are a Java shop, so they can't provide me with any working example or code snippets. So, I'm stuck trying to figure this stuff out.

    I'm at a loss on how to get this figured out.

    Take a look at Microsoft Azure. You can sign up for a free account, and deploy services.

    Thanks, but I don't think that'll help me in writing a client to connect to that third party's webservice.

    Why, the concept is the same. Take a look here: http://msdn.microsoft.com/en-us/library/bb165052.aspx

    I'm thinking the problem is related to the formatting of the headers for WSSE. Not real sure how to tackle that.

    Re: How can I consume a webservice that uses WSSE?

    Thanks for your help. I was finally able to get it connecting. I had to write out some classes to handle custom headers. Hmmm..that link you attached seems to be a bit more elegant way of doing it than what I ended up doing. Thanks again man!
