Not able to access WCF Rest method hosted in IIS 7 remotely or locally

My problem looks similar to the one discussed in this thread Checked this thread and went through all the steps but my problem exists

Running the service directly from visual studio, I am able to invoke the REST WebGet method using http://localhost:12827/HighONDealsService/GetDeals/43.1656/-77.6114, but after deploying my service in IIS on a remote server i'm unable to access the WebGet method anymore.

My service can be seen here http://155.98.38.135:12827/HighONDealsService.svc

I'm able to reach the service, and even the help page for the service but not the actual service method http://155.98.38.135:12827/HighONDealsService/help

My actual service directory has Read & Execute permissions for Network Service and IIS_IUSRS.

My Global.asax.cs file looks like 

protected void Application_Start(object sender, EventArgs e)
    {
        RouteTable.Routes.Add(new ServiceRoute("HighONDealsService", new WebServiceHostFactory(), typeof(HighONDealsService)));
    }

I tried the steps in the above mentioned thread, but to no avail This is my web.config :

Actual Service Implementation :

/// <summary>

/// </summary>
[ServiceContract]
public interface IHighONDealsService
{
    /// <summary>
    /// 
    /// </summary>
    /// <param name="userLat"></param>
    /// <param name="userLong"></param>
    /// <returns></returns>
    [OperationContract]
    [WebGet(UriTemplate = "GetDeals/{userLat}/{userLong}")]
    List<DealObject> GetDeals(string userLat, string userLong);        
}

/// <summary>
/// 
/// </summary>
[DataContract]
public class DealObject
{
    [DataMember]
    public string City;

    [DataMember]
    public string Category;

    [DataMember]
    public string SearchResult;

    [DataMember]
    public decimal Latitude;

    [DataMember]
    public decimal Longitude;

    [DataMember]
    public string Deals;

    [DataMember]
    public string Address;
}

The Fiddler Trace for the service running from a visual studio instance shows the full xml response <ArrayOfDealObject xmlns="http://schemas.datacontract.org/2004/07/HighONDealsService" xmlns:i="http://www.w3.org/2001/XMLSchema-instance"><DealObject><Address i:nil="true"/><Category>Bars</Category><City>Rochester</City><Deals>Stay late and get drunk - free drinks on the house after 10pm</Deals><Latitude>43.160850</Latitude><Longitude>-77.601294</Longitude><SearchResult>Tavern 58 At Gibbs</SearchResult></DealObject><DealObject><Address i:nil="true"/><Category>Hospital</Category><City>Rochester</City><Deals>Get your pet checked up for free all winter long</Deals><Latitude>43.176582</Latitude><Longitude>-77.551338</Longitude><SearchResult>Laurelton Animal Hospital</SearchResult></DealObject><DealObject><Address i:nil="true"/><Category>Airport</Category><City>Rochester</City><Deals>Enjoy your stay with complimentary spa sessions</Deals><Latitude>43.130763</Latitude><Longitude>-77.668665</Longitude><SearchResult>Fairfield Inn Rochester Airport</SearchResult></DealObject><DealObject><Address i:nil="true"/><Category>Pizza</Category><City>Rochester</City><Deals>Get 1 large Pizza with every Sheet Pizza</Deals><Latitude>43.138420</Latitude><Longitude>-77.594986</Longitude><SearchResult>Salvatore's Pizzeria</SearchResult></DealObject><DealObject><Address i:nil="true"/><Category>Restaurants</Category><City>Rochester</City><Deals>Dollar 5 discount on every takeaway</Deals><Latitude>43.153626</Latitude><Longitude>-77.608005</Longitude><SearchResult>Dinosaur Barbeque</SearchResult></DealObject><DealObject><Address i:nil="true"/><Category>Bars</Category><City>Rochester</City><Deals>Happy hours all this month</Deals><Latitude>43.119709</Latitude><Longitude>-77.619911</Longitude><SearchResult>Sheridan's Pub</SearchResult></DealObject><DealObject><Address i:nil="true"/><Category>Gas Station</Category><City>Rochester</City><Deals>Get 3 car washes for dollar 10 only</Deals><Latitude>43.138942</Latitude><Longitude>-77.669807</Longitude><SearchResult>Anthony's Sunoco</SearchResult></DealObject></ArrayOfDealObject>

But the Fiddler Trace for the service hosted in IIS shows blank <ArrayOfDealObject xmlns="http://schemas.datacontract.org/2004/07/HighONDealsService" xmlns:i="http://www.w3.org/2001/XMLSchema-instance"/>

What am I doing wrong here?

Solution

  • The problem seems to be with Windows Authentication/Integrated Security for Entity Framework connectivity to the backend. Working on it :)
