405 method not allowed using [webHttpBinding] - wcf

Question

I'm getting problems with jquery call wcf. I've already search and found some solutions but it still raise me an error "405 method not allowed". Below is may code
-Interface
using System;
using System.Collections.Generic;
using System.Linq;
using System.Runtime.Serialization;
using System.Text;
using System.ServiceModel.Activation;
using System.ServiceModel.Web;
using System.ServiceModel;
namespace WcfServiceLibrary
{
// NOTE: You can use the "Rename" command on the "Refactor" menu to change the interface name "IContactService" in both code and config file together.
[ServiceContract]
public interface IContactService
{
[WebInvoke(Method = "GET",
ResponseFormat = WebMessageFormat.Json)]
[OperationContract]
Contact GetContactInfo();
}
}
My service
using System;
using System.Collections.Generic;
using System.Linq;
using System.Runtime.Serialization;
using System.ServiceModel;
using System.Text;
using System.ServiceModel.Activation;
using System.ServiceModel.Web;
using System.ServiceModel;
namespace WcfServiceLibrary
{
// NOTE: You can use the "Rename" command on the "Refactor" menu to change the class name "ContactService" in both code and config file together.
[AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Allowed)]
public class ContactService : IContactService
{
public Contact GetContactInfo()
{
ContactBL contactBL = new ContactBL();
return contactBL.GetContact();
}
}
}
My object
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Runtime;
using System.Runtime.Serialization;
namespace WcfServiceLibrary
{
[DataContract]
public class Contact
{
[DataMember]
public int Id {get;set;}
[DataMember]
public string Fullname {get; set;}
[DataMember]
public string email { get; set; }
}
}
BL
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
namespace WcfServiceLibrary
{
class ContactBL
{
public ContactBL() { }
public Contact GetContact()
{
return new Contact {email="thang.nguyen#saas.com.vn", Fullname="NVTThang",Id=2 };
}
}
}
And also my WCF configuration:
<?xml version="1.0"?>
<configuration>
<system.web>
<compilation debug="true" targetFramework="4.0"/>
</system.web>
<system.serviceModel>
<bindings>
<webHttpBinding>
<binding name="webBinding">
<security mode="None" />
</binding>
</webHttpBinding>
</bindings>
<services>
<service behaviorConfiguration="myBehavior" name="WcfServiceLibrary.ContactService">
<endpoint address="ajaxEp" behaviorConfiguration="epAjaxBehavior"
binding="webHttpBinding" bindingConfiguration="webBinding" name="epWebHttp"
contract="WcfServiceLibrary.IContactService" />
<endpoint address="mex" binding="mexHttpBinding" name="epMex"
contract="IMetadataExchange" />
</service>
</services>
<behaviors>

</behavior>

<serviceBehaviors>

</baseAddressPrefixFilters>
</serviceHostingEnvironment>
</system.serviceModel>
<system.webServer>
<modules runAllManagedModulesForAllRequests="true"/>
</system.webServer>
</configuration>
The I deploy my wcf on IIS 7.5 then I created a web client using jquery ajax call to my service.
$.ajax({
type: "GET",
url: "http://localhost/WcfTestService/Service.svc/ajaxEp/GetContactInfo",
data: '',
contentType: "application/json;charset=utf-8",
dataType: "json",
processdata: true,
success: function (msg) {
alert(msg);
//ServiceSucceeded(msg);
},
error: ServiceFailed
});
function ServiceFailed(err){
alert(err.responseText);
return;
}
when I call my service it always raises me "405 Method Not Allowed" and I've tried aspnet_regiis -i and ServiceModelReg -i but it didn't effect. Please suggest me any solutions.
Thanks in advance!

Answer 1

I can see a few problems in your service:
For "GET" requests, you should use WebGet, instead of WebInvoke, on your contract:
[ServiceContract]
public interface IContactService
{
[WebGet(ResponseFormat = WebMessageFormat.Json)]
[OperationContract]
Contact GetContactInfo();
}
In your endpoint behavior you have 2 behaviors for scripting: webHttp and enableWebScript. You only need the former. The latter is for integration with ASP.NET AJAX specifically.
<endpointBehaviors>
<behavior name="epAjaxBehavior">
<webHttp />
</behavior>
</endpointBehaviors>
This probably isn't causing any issues, but in the $.ajax call, you don't need to specify a content-type, since it's a GET request (so there's no content). Also, since you aren't passing any parameter, you also don't need the data parameter.
$.ajax({
type: "GET",
url: "http://localhost/WcfTestService/Service.svc/ajaxEp/GetContactInfo",
dataType: "json",
success: function (msg) {
alert(msg);
//ServiceSucceeded(msg);
},
error: ServiceFailed
});

Answer 2

Try this in your service:
[ScriptMethod]
public Contact GetContact(...)
