Question

I m aware that WCF RIA Services has a Microsoft.ServiceModel.DomainServices.Hosting.JsonEndpointFactory that I can use to enable JSON. I need to enable cross-domain calls via JSONP. Is there an existing DomainServiceEndpointFactory that will accomplish this?

Answer 1

我只需要这样做——我放弃了JsonEndpointFactory,并随同在那里具有约束力的那样,然后用新类别增加了一个终点。

namespace Bodge
{
    public class JsonPEndpointFactory : JsonEndpointFactory
    {
        public override IEnumerable<ServiceEndpoint> CreateEndpoints(DomainServiceDescription description, DomainServiceHost serviceHost)
        {
            IEnumerable<ServiceEndpoint> endPoints = base.CreateEndpoints(description, serviceHost);
            foreach (ServiceEndpoint endPoint in endPoints)
            {
                if (endPoint.Binding is WebHttpBinding)
                {
                    ((WebHttpBinding)endPoint.Binding).CrossDomainScriptAccessEnabled = true;
                }
            }

            return endPoints;
        }
    }
}

  <endpoints>
    <add name="JSONP" type="Bodge.JsonPEndpointFactory, Bodge, Version=1.0.0.0"/>
  </endpoints>

Then access your service with the endpoint and the callback query param e.g. http://blah/service.svc/JSONP/GetStuff?callback=callbackname

Hope that helps, Chris.
