使用WebScriptEndpoint使用JavaScript消耗WCF服务

Question

I searched on net but didn't find any suitable article explaining how to consume a WCF service using javascript, and especially a WebScriptEndpoint.

Can any one give any direction on this?

Thanks

Here is a good article about REST services : http://msdn.microsoft.com/en-us/magazine/dd315413.aspx

To summarize, you want an endpoint configured with webHttpBinding. This endpoint should have a behavior with webHttp enabled :

<services>
  <service name="TestService">
    <endpoint address="test" binding="webHttpBinding"  behaviorConfiguration="restBehavior" contract="ITestService"/>
  </service>
</services>

Behavior :

<behavior name="restBehavior">
  <webHttp/>
</behavior>

Then in your service interface :

[ServiceContract]
public interface ITestService
{
    [OperationContract]
    [WebGet(UriTemplate = "test?p={p}", ResponseFormat = WebMessageFormat.Json)]
    string Test(string p);
}

You can use WebGet or WebInvoke attribute (depends if you want to GET or POST)...
