Written or started to write a WEB API rest service in WCF. It's all going relatively well. However, I've come across a small problem. I've implemented this;
For key validation. (I'm not sure if this is the correct approach for WCF WEB API, since it looks more like the rest service implementation).
Anyway, it seems to work. However, when the api key is not provided the exception is not been displayed in the browser. I.e. if I provide the key, it returns correctly, if I don't it just shows a blank page.
private static void CreateErrorReply(OperationContext operationContext, string key)
{
// The error message is padded so that IE shows the response by default
using (var sr = new StringReader("<?xml version=\"1.0\" encoding=\"utf-8\"?>" + APIErrorHTML))
{
XElement response = XElement.Load(sr);
using (Message reply = Message.CreateMessage(MessageVersion.None, null, response))
{
HttpResponseMessageProperty responseProp = new HttpResponseMessageProperty() { StatusCode = HttpStatusCode.Unauthorized, StatusDescription = String.Format("'{0}' is an invalid API key", key) };
responseProp.Headers[HttpResponseHeader.ContentType] = "text/html";
reply.Properties[HttpResponseMessageProperty.Name] = responseProp;
operationContext.RequestContext.Reply(reply);
// set the request context to null to terminate processing of this request
operationContext.RequestContext = null;
}
}
}
Instead of this showing an error, the result is a blank response. Can anyone help?
