Handler for Request not found:

Question

I am building a service stack for the first time: hello world.

I have followed the step by step guide in here:

but it is giving me an error: Handler for Request not found: what could be the missing part? thanks.

here is my global.asax.cs

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Security;
using System.Web.SessionState;
using ServiceStack.ServiceHost;
using ServiceStack.WebHost.Endpoints;

namespace ServiceStack.SearchService
{
    public class Global : System.Web.HttpApplication
    {
        public class Hello { public string Name { get; set; } }
        public class HelloResponse { public string Result { get; set; } }
        public class HelloService : IService<Hello>
        {
            public object Execute(Hello request)
            {
                return new HelloResponse { Result = "Hello, " + request.Name };
            }
        }



        /// Web Service Singleton AppHost
        public class HelloAppHost : AppHostBase
        {
            //Tell Service Stack the name of your application and where to find your web services
            public HelloAppHost()
                : base("Hello Web Services", typeof(HelloService).Assembly) { }

            public override void Configure(Funq.Container container) { }
        }

        protected void Application_Start(object sender, EventArgs e)
        {
            //Initialize your application
            var appHost = new HelloAppHost();
            appHost.Init();
        }


        void Application_End(object sender, EventArgs e)
        {
            //  Code that runs on application shutdown

        }

        void Application_Error(object sender, EventArgs e)
        {
            // Code that runs when an unhandled error occurs

        }

        void Session_Start(object sender, EventArgs e)
        {
            // Code that runs when a new session is started

        }

        void Session_End(object sender, EventArgs e)
        {
            // Code that runs when a session ends. 
            // Note: The Session_End event is raised only when the sessionstate mode
            // is set to InProc in the Web.config file. If session mode is set to StateServer 
            // or SQLServer, the event is not raised.

        }

    }
}

here is my web.config:

I browse it by typing in the browser.

http://localhost:50097/ServiceStack.SearchService/servicestack/metadata

Answer 1

There is a small step missing from that list that you need if your going to map the services to a custom path. You can find it here:

To quote the missing step:

You also need to configure the root path in your AppHost.

public override void Configure(Container container)
{
    SetConfig(new EndpointHostConfig { ServiceStackHandlerFactoryPath = "api" });
}

Where "api" is the name of the custom path you are using.

Answer 2

It looks like you're trying to host ServiceStack both at the / root path and at a mixture of /servicestack and /api custom paths. You need to pick one of them, not a combination of all 3. Here is the config if you want to host at the / root path:

<system.web>
  <httpHandlers>
    <add path="*" type="ServiceStack.WebHost.Endpoints.ServiceStackHttpHandlerFactory, ServiceStack" verb="*"/>
  </httpHandlers>
</system.web>

<!-- Required for IIS 7.0 -->
<system.webServer>
  <handlers>
    <add path="*" name="ServiceStack.Factory" type="ServiceStack.WebHost.Endpoints.ServiceStackHttpHandlerFactory, ServiceStack" verb="*" preCondition="integratedMode" resourceType="Unspecified" allowPathInfo="true" />
  </handlers>
</system.webServer>

The above should replace every other ServiceStack config mapping. Once you've done this you should be able to view the metadata page at:

http://localhost:50097/metadata

Note: If you're running ASP.NET on a port it is unlikely that you also have the Virtual Directory path /ServiceStack.SearchService/.

Answer 3

I had this exact issue I had and could not find a straight answer to - getting a 403.14 error on the simplest ServiceStack demo.

..:: Simple Answer ::..

Your answer is simple. You have confused your handlers by providing 3 instead of one as mentioned by Mythz. Also, You don't have a specified route for your request.

[Route("/hello")]
public class Hello { public string Name { get; set; } }

This will resolve both your 403.13 error (semantic issue) and you can go to your http://{localdomain}:{port}/hello and actually see the metadata (substitute the {port} with the actual port number IIS Express assigned to you). Without this adjustment, you'll need to go to http://{localdomain}:{port}/metadata.

..:: Detailed Answer ::..

Routing, as it relates to IIS in ServiceStack is done by semantics/convention. Since these routes are dynamic, when IIS is not provided proper routing at run time, it assumes that there is a folder issue (physical path) and throws the 403.14 error. At the same time, if you provide more than one path where there should be only one, bad things happen at run time when everything is wired up.

Just to be sure you have all the essentials, here are all the adjustments you need to make to the original code provided.

a. Adjust the web config file to handle just one path as explored in Mythz response

<system.web>
  <httpHandlers>
    <add path="*" type="ServiceStack.WebHost.Endpoints.ServiceStackHttpHandlerFactory, ServiceStack" verb="*"/>
  </httpHandlers>
</system.web>

<!-- Required for IIS 7.0 -->
<system.webServer>
  <handlers>
    <add path="*" name="ServiceStack.Factory" type="ServiceStack.WebHost.Endpoints.ServiceStackHttpHandlerFactory, ServiceStack" verb="*" preCondition="integratedMode" resourceType="Unspecified" allowPathInfo="true" />
  </handlers>
</system.webServer>

b. Make the route adjustment described earlier in this post.
