How would you implement API key in WCF Data Service?
- by rushonerok
Is there a way to require an API key in the URL / or some other way of passing the service a private key in order to grant access to the data?
I have this right now...
using System;
using System.Data.Services;
using System.Data.Services.Common;
using System.Collections.Generic;
using System.Linq;
using System.ServiceModel.Web;
using Numina.Framework;
using System.Web;
using System.Configuration;
[System.ServiceModel.ServiceBehavior(IncludeExceptionDetailInFaults = true)]
public class odata : DataService {
public static void InitializeService(DataServiceConfiguration config) {
config.SetEntitySetAccessRule("*", EntitySetRights.AllRead);
//config.SetServiceOperationAccessRule("*", ServiceOperationRights.All);
config.DataServiceBehavior.MaxProtocolVersion = DataServiceProtocolVersion.V2;
}
protected override void OnStartProcessingRequest(ProcessRequestArgs args) {
HttpRequest Request = HttpContext.Current.Request;
if(Request["apikey"] != ConfigurationManager.AppSettings["ApiKey"])
throw new DataServiceException("ApiKey needed");
base.OnStartProcessingRequest(args);
}
}
...This works but it's not perfect because you cannot get at the metadata and discover the service through the Add Service Reference explorer. I could check if $metadata is in the url but it seems like a hack. Is there a better way?
