Hi! I've created an ADO.Net
Data Service hosted in a Azure worker role. I want to pass credentials from a simple console client to the service then validate them using a QueryInterceptor. Unfortunately, the credentials don't seem to be making it over the wire.
The following is a simplified version of the code I'm using, starting with the DataService on the server:
using System;
using
System.
Data.Services;
using
System.Linq.Expressions;
using
System.ServiceModel;
using
System.Web;
namespace Oslo.Worker
{
[ServiceBehavior(AddressFilterMode = AddressFilterMode.Any)]
public class AdminService : DataService<OsloEntities>
{
public static void InitializeService(
IDataServiceConfiguration config)
{
config.SetEntitySetAccessRule("*", EntitySetRights.All);
config.SetServiceOperationAccessRule("*", ServiceOperationRights.All);
}
[QueryInterceptor("Pairs")]
public Expression<Func<Pair, bool>> OnQueryPairs()
{
// This doesn't work!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
if (HttpContext.Current.User.Identity.Name != "ADMIN")
throw new Exception("Ooops!");
return p => true;
}
}
}
Here's the AdminService I'm using to instantiate the AdminService in my Azure worker role:
using System;
using
System.
Data.Services;
namespace Oslo.Worker
{
public class AdminHost : DataServiceHost
{
public AdminHost(Uri baseAddress)
: base(typeof(AdminService), new Uri[] { baseAddress })
{
}
}
}
And finally, here's the client code.
using System;
using
System.
Data.Services.Client;
using
System.Net;
using Oslo.Shared;
namespace Oslo.ClientTest
{
public class AdminContext : DataServiceContext
{
public AdminContext(Uri serviceRoot, string userName,
string password) : base(serviceRoot)
{
Credentials = new NetworkCredential(userName, password);
}
public DataServiceQuery<Order> Orders
{
get
{
return base.CreateQuery<Pair>("Orders");
}
}
}
}
I should mention that the code works great with the signal exception that the credentials are not being passed over the wire.
Any help in this regard would be greatly appreciated!
Thanks....
