wsdl with no serialization info - wcf

Question

I am trying to send a request to a web service. The wsdl can be seen here
https://amsel.dpwn.net/abholportal/gw/lp/schema/1.0/var3ws.wsdl
Creating a request is straight forward
BookLabelRequest request = new BookLabelRequest();
RpPartnerType rpt = new RpPartnerTypeClient();
dhlService.BookLabelResponse response = rpt.BookLabel(new dhlService.BookLabelRequest());
but how do i pass the required parameters to it when there is no serializable BookLabelRequest exposed? and how do i pass the username/password in the header?
Sample SOAP request:
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:var="https://amsel.dpwn.net/abholportal/gw/lp/schema/1.0/var3bl">
<soapenv:Header>
<wsse:Security soapenv:mustUnderstand="1" xmlns:wsse="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-secext-1.0.xsd">
<wsse:UsernameToken>
<wsse:Username>username</wsse:Username>
<wsse:Password Type="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-username-token-profile-1.0#PasswordText">password</wsse:Password>
</wsse:UsernameToken>
</wsse:Security>
</soapenv:Header>
<soapenv:Body>
<var:BookLabelRequest portalId ="OnlineRetoure" deliveryName="Deutschland_Var3"
shipmentReference="notreturnedonlabel" customerReference="CustomerRef1234567890"
labelFormat="PDF" senderName1="Markus" senderName2="Beck"
senderCareOfName="actualnotinuse" senderContactPhone=""
senderStreet="Buschmühlenstraße" senderStreetNumber="40"
senderBoxNumber="" senderPostalCode="58093" senderCity="Hagen"/>
</soapenv:Body>
The wsdl file isn't mine so i can't edit it. Is there any other way to import this. I tried to create a data contract from the xsd using svcutil but i got the error message:
The input read from "https://amsel.dpwn.net/abholportal/gw/lp/schema/1.0/
var3bl.xsd" is inconsistent with other options
I tried passing the username and password to the proxy as well
RpPartnerType test = new RpPartnerTypeClient();
((RpPartnerTypeClient)test).ClientCredentials.UserName.UserName = "username";
((RpPartnerTypeClient)test).ClientCredentials.UserName.Password = "password";
dhlService.BookLabelResponse response = test.BookLabel(new dhlService.BookLabelRequest());
but got the error: Authentication failed: No username given
The binding security is:
<security mode="Transport">
<transport clientCredentialType="None" proxyCredentialType="None"
realm="" />
<message clientCredentialType="UserName" algorithmSuite="Default" />
</security>

Answer 1

Your WSDL is importing XSD with serialization info from other path:
https://amsel.dpwn.net/abholportal/gw/lp/schema/1.0/var3bl.xsd
but location in WSDL should specify full this path.
If you need to use UserNameToken profile you must first specify binding for your your client:
<bindings>
<basicHttpBinding>
<binding name="secured">
<security mode="TransportWithMessageCredential">
<transport clientCredentialType="UserName" />
</security>
</binding>
</basicHttpBinding>
</bindings>
And use this binding in your client endpoint:
<client>
<endpoint address="..." name="..." contract="..." binding="basicHttpBining"
bindingConfiguration="secured" />
</client>
Once you have your client configured you need to create proxy of the service ans set credentials"
proxy.ClientCredentials.UserName.UserName = ...;
proxy.ClientCredentials.UserName.Password = ...;

Create a HttpWebRequest according to Mike Hadlow's blog and sent that.

May be better ways to achieve this but it worked.
