I am creating a WCF service in one of my DNN modules replacing an existing SOAP based service.

 I used wcf.exe to create to create the service from the old wsdl file by following the blog.

I need to make the SOAP service statefull by manging the login in the server.

I did some research and created a method to send the “.DOTNETNUKE” cookie which is used to manage user login in DNN using the the following code

OperationContext context = OperationContext.Current;

            MessageProperties prop = context.IncomingMessageProperties;

            RemoteEndpointMessageProperty endpoint = prop[RemoteEndpointMessageProperty.Name] as RemoteEndpointMessageProperty;

            string ip = endpoint.Address;

            var loginStatus = new UserLoginStatus();

            var portalname = "";

            var objUser = UserController.ValidateUser(0, request.Body.Email,request.Body.Password, "", portalname, ip, ref loginStatus);

            if (loginStatus != UserLoginStatus.LOGIN_FAILURE || loginStatus != UserLoginStatus.LOGIN_USERNOTAPPROVED)

            {

                    UserController.UserLogin(0, objUser, portalname, ip, true);

            }

    var cookie=FormsAuthentication.GetAuthCookie(objUser.Username, true);

WebOperationContext.Current.OutgoingResponse.Headers.Add($"Set-Cookie: {cookie.Name}={cookie.Value}; expires={cookie.Expires}; path={cookie.Path}; {(cookie.HttpOnly?"HttpOnly":"")}");

            return new UserAuthenticationResponse(new UserAuthenticationResponseBody() { Token = cookie.Value });

The cookie is then sent along with the subsequent SOAP requests.

I use the following code to get the user name from the cookie;

   var cookie =  WebOperationContext.Current.IncomingRequest.Headers[HttpRequestHeader.Cookie];

            cookie= cookie.Replace(".DOTNETNUKE=", "");

          var temp=  FormsAuthentication.Decrypt(cookie);

       var userName=     temp.Name;

           UserController.Instance.GetCurrentUserInfo

            var user = UserController.GetUserByName(0, userName);

Is this a valid method or is there a better method to get the user id from the cookie.

I also want to set dotetnuke variables like UserController.Instance.GetCurrentUserInfo

So that I can use it in my business logic. Is there any way to do that?
