Ajax Url to Routed WCF in Asp.Net 4 Web Forms

Question

I implemented Routing in Asp.Net 4 Web App. With aspx file it works fine, but it doesn't work with WCF.

I have WCF which is called from javascipt file by ajax request.

My WCF code is:

[ServiceContract(Namespace = "")]
    [AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Allowed)]
    public class Signature
    {

        /// <summary>
        /// Get signature info by email address.
        /// </summary>        
        [OperationContract]        
        [WebInvoke(ResponseFormat = WebMessageFormat.Json)]
        public string GetSignatureInfo(string email)
        {
            ...
        }
    }
}

Web.config:

<services>     
  <service name="WEB.Services.Signature">
    <endpoint address="" behaviorConfiguration="WEB.Services.SignatureAspNetAjaxBehavior"
      binding="webHttpBinding" contract="WEB.Services.Signature" />
  </service>
</services>

javascript:

var _data = {
    "email": self.email.val()
};

$.ajax({
    url: '../Signature'
    , type: 'POST'
    , dataType: 'json'
    , data: JSON.stringify(_data)
    , success: function (data) {
        console.log('success');
    }
    , error: function () {
        console.log('error');
    }
});

Global.asax:

void RegisterRoutes(RouteCollection routes)
{
    var sr = new ServiceRoute("Signature", new WebServiceHostFactory(), typeof(Signature));
    sr.Url = "Services/Signature.svc/GetSignatureInfo";
    routes.Add(sr);
}


void Application_Start(object sender, EventArgs e)
{
    // Code that runs on application startup

    RegisterRoutes(RouteTable.Routes);            
}

I get "NetworkError: 404 Not Found - _http://www.my-project.com/Signature". Where am I wrong or what ajax url should be ?!!! Please, help. Thanks in advance.

It looks like you hit "Post your question" without having finished it. You can edit the question to add the code you were going to add and also your question. — Burhan Ali, Sep 01 '13 at 09:03
Try fully qualifying the URL you're passing in the JavaScript - instead of `url: '../Signature'` use `url: 'http://somedomain/url: '../Signature'`. Also, your method takes a parameter, so you probably need to pass that in as well. — Tim, Sep 01 '13 at 22:06

My work colleague has found a solution: The problem was in IIS configuration - If my app is under Default Site , I should add ajax url with prefix of project. For example, if my Service is located in Web project, I should enter url like : '/Web/Services/MyService/MyFunction' in js file. The same url should be on Global.asax file, in ServiceRoute url, but without first '/'. In this case, it will work fine locally,but there will be a problem to put it on production server.

The optimal solution: 1. IIS : add web site, configure physical path to him, change its port(!!!). 2. .js + Global.asax : just remove project name from url in both places. So, the url will be like : in js file '/Services/MyService/MyFunction' and in Global.asax 'Services/MyService/MyFunction' (without first '/')

That's all. Big thanks to Miri(colleague).
