  1. POWCF - how to set "enableWebScript" dynamically?
    text
    copied!<p>I'm working on my first WCF service, which will support several Ajax calls. I have an endpoint configured this way:</p> <pre><code> &lt;service behaviorConfiguration="ServiceBehavior" name="AQM"&gt; &lt;endpoint address="" behaviorConfiguration="web" binding="webHttpBinding" bindingConfiguration="Binding1" contract="IAQM" /&gt; &lt;/service&gt; </code></pre> <p>and my behavior configuration:</p> <pre><code> &lt;endpointBehaviors&gt; &lt;behavior name="web"&gt; &lt;webHttp /&gt; &lt;enableWebScript /&gt; &lt;/behavior&gt; &lt;/endpointBehaviors&gt; </code></pre> <p>I need to create my own error handling so that I can format some specific information back to the client (see here <a href="http://zamd.net/2008/07/08/error-handling-with-webhttpbinding-for-ajaxjson/" rel="nofollow">http://zamd.net/2008/07/08/error-handling-with-webhttpbinding-for-ajaxjson/</a>). My WebServiceHostFactory looks like this:</p> <pre><code>public class MyServiceFactory : WebServiceHostFactory { public override ServiceHostBase CreateServiceHost(string constructorString, Uri[] baseAddresses) { var sh = new ServiceHost(typeof(AQM), baseAddresses); sh.Description.Endpoints[0].Behaviors.Add(new WebHttpBehaviorEx()); return sh; } protected override ServiceHost CreateServiceHost(Type serviceType, Uri[] baseAddresses) { return base.CreateServiceHost(serviceType, baseAddresses); } } public class WebHttpBehaviorEx : WebHttpBehavior { protected override void AddServerErrorHandlers(ServiceEndpoint endpoint, EndpointDispatcher endpointDispatcher) { // Clear default error handlers endpointDispatcher.ChannelDispatcher.ErrorHandlers.Clear(); // Add our own error handler endpointDispatcher.ChannelDispatcher.ErrorHandlers.Add(new ErrorHandlerEx()); } </code></pre> <p>However, after I created my own error handler, it seems it overrides the "enableWebScript" setting I had in my config above, which I think makes sense because now I'm creating my very own behavior dynamically which doesn't have any of the config settings above. </p> <p>I read that this setting should be used with WCF/Ajax for security purposes (see here <a href="http://www.asp.net/ajaxlibrary/Using%20JSON%20Syntax%20with%20Ajax.ashx" rel="nofollow">http://www.asp.net/ajaxlibrary/Using%20JSON%20Syntax%20with%20Ajax.ashx</a>). So my question is, how can I set the the "enableWebScript" setting on my dynamically created behavior? Or is it not possible? </p> <p>Update (6/1/2011): I'm also looking to dynamically change the behavior to use Windows credentials for authentication. In the config file it's done like this:</p> <pre><code>&lt;bindings&gt; &lt;webHttpBinding&gt; &lt;binding name="Binding1"&gt; &lt;security mode="TransportCredentialOnly"&gt; &lt;transport clientCredentialType="Windows" /&gt; &lt;/security&gt; &lt;/binding&gt; &lt;/webHttpBinding&gt; &lt;/bindings&gt; </code></pre> <p>This is another setting I need to make programmatically since it seems to ignore the config setting.</p>
