POHow to consume non-IIS hosted, WCF, C# web service from Delphi 2007?
text
Body
copied!<p>I've written a fairly simple little C# web service, hosted from a standalone EXE via WCF. The code - somewhat simplified - looks like this:</p> <pre><code>namespace VMProvisionEXE { class EXEWrapper { static void Main(string[] args) { WSHttpBinding myBinding = new WSHttpBinding(); myBinding.Security.Mode = SecurityMode.None; Uri baseAddress = new Uri("http://bernard3:8000/VMWareProvisioning/Service"); ServiceHost selfHost = new ServiceHost(typeof(VMPService), baseAddress); try { selfHost.AddServiceEndpoint(typeof(IVMProvisionCore), myBinding, "CoreServices"); ServiceMetadataBehavior smb = new ServiceMetadataBehavior(); smb.HttpGetEnabled = true; smb.MetadataExporter.PolicyVersion = PolicyVersion.Policy12; selfHost.Description.Behaviors.Add(smb); // Add MEX endpoint selfHost.AddServiceEndpoint(ServiceMetadataBehavior.MexContractName, MetadataExchangeBindings.CreateMexHttpBinding(), "mex"); selfHost.Open(); Console.WriteLine("The service is ready."); Console.ReadLine(); </code></pre> <p>The rest of the C# code; the class VMPService above implements VMProvisionCore.IVMProvisionCore.</p> <pre><code>namespace VMProvisionCore { [ServiceContract(Namespace = "http://Cisco.VMProvision.Core", ProtectionLevel = System.Net.Security.ProtectionLevel.None)] public interface IVMProvisionCore { [OperationContract] bool AuthenticateUser(string username, string password); } </code></pre> <p>I can easily create a Visual Studio 2008 client application that consumes this service. No problems. But using Delphi 2007 is a different issue. I can use the WSDL importer in Delphi to retrieve the WSDL from (in this case) <a href="http://bernard3:8000/VMWareProvisioning/Service?wsdl" rel="noreferrer">http://bernard3:8000/VMWareProvisioning/Service?wsdl</a> The import unit compiles just fine. I have to initialize the proxy by hand since the WSDL doesn't contain a URL (notice the extra "/CoreServices" as shown in the C# code):</p> <pre><code>var Auth: AuthenticateUser; AuthResponse: AuthenticateUserResponse; CoreI: IVMProvisionCore; begin CoreI:= GetIVMProvisionCore(False, 'http://bernard3:8000/VMWareProvisioning/Service/CoreServices'); Auth:= AuthenticateUser.Create; try Auth.username:= 'test'; Auth.password:= 'test'; AuthResponse:= CoreI.AuthenticateUser(Auth); finally FreeAndNIL(Auth); end; </code></pre> <p>The above code will generate an error when it hits the "CoreI.AuthenticateUser(Auth);". The error is "<strong>Cannot process the message because the content type 'text/xml; charset="utf-8" was not the expected type 'application/soap+xml; charset=utf-8.</strong>"</p> <p>I suspect that I've got a stupid little error somewhere, perhaps during the import of the WSDL or in the connection options or something. Can anyone help?</p>
