GetAuthenticatedCustomer in a WPF application

Hi (dmorley :-)),

I'm building a WPF app that handles order dispatched. When I try and use the nop service

When I try and use IOrderProcessingService Ship I get the exception below. It is something to do with notifying the customer because it uses - GetAuthenticatedCustomer

The code it doesn't like is

if (_httpContext == null ||
                _httpContext.Request == null ||
                !_httpContext.Request.IsAuthenticated ||
                !(_httpContext.User.Identity is FormsIdentity))

I figured it was something to do with it being a WPF app and not a web app with http context, but doesn't nop fake http context if its not there?

Narrowed it down to this line

!_httpContext.Request.IsAuthenticated

_httpContext.Request.IsAuthenticated = '_httpContext.Request.IsAuthenticated' threw an exception of type 'System.NotImplementedException'

A.M is this something you have come across in Unit Testing?

FakeHttpRequest does not implement IsAuthenticated property (unit tests do not use it). Open this file and add it:

public override bool IsAuthenticated
{
   get { return false; }
}

Thank you!

Used  public bool IsAuthenticated { get { return false; } } without the override as HttpResponseBase does have the IsAuthenticated method and it works great.

Had an issue with

Here is the new FakeResponse Script with 2 new methods in case you want to use it in the source (will save me some work at upgrade time :-))

using System.Text;
using System.Web;

namespace Nop.Core.Fakes
{
    public class FakeHttpResponse : HttpResponseBase
    {
        private readonly HttpCookieCollection _cookies;
        private readonly StringBuilder _outputString = new StringBuilder();

       public FakeHttpResponse(HttpCookieCollection cookies)
        {
            _cookies = cookies;
            if (_cookies == null)
                _cookies = new HttpCookieCollection();
        }

        public string ResponseOutput
        {
            get { return _outputString.ToString(); }
        }

        public override int StatusCode { get; set; }

        public override string RedirectLocation { get; set; }

        public override void Write(string s)
        {
            _outputString.Append(s);
        }

        public override string ApplyAppPathModifier(string virtualPath)
        {
            return virtualPath;
        }

        public bool IsAuthenticated { get { return false; } }

        public override HttpCookieCollection Cookies
        {
            get { return _cookies; }
        }
    }
}

and obviously I changed the call to Response in FakeHTTPContext to pass _cookies

   public override HttpResponseBase Response
        {
            get
            {
                return _response ?? new FakeHttpResponse(_cookies);
            }
        }

Thanks again Andrei
