How can I query an AppHost for a specific route? - servicestack

Question

Basically I have following architecture:
Website-project (1)
Domain-project (2)
Api-project (3)
Dependencies:
1 uses 2 and 3
3 uses 2
2 uses nothing
In my Api-project I define a concrete implementation of ServiceStack.Webhost.Endpoints.AppHostBase, eg ApiAppHost:
public sealed class ApiAppHost : AppHostBase
{
private ApiAppHost()
: base("Description", typeof (ApiAppHost).Assembly) {}
public override void Configure(Container container)
{
this.SetConfig(new EndpointHostConfig
{
ServiceStackHandlerFactoryPath = "api"
});
this.Routes.Add<Foo>("/foo", "POST");
}
public static void Initialize()
{
var instance = new ApiAppHost();
instance.Init();
}
}
This is pretty straight-forward.
Now I want to query my this.Routes (in combination with EndpointHostConfig.ServiceStackHandlerFactoryPath) from my Website-project to get the specific path for Foo.
How can I do that without creating an interceptor on my own? Does ServiceStack.Net provide anything which fits?

Answer 1

Currently I am doing something like this
public static class AppHostBaseExtensions
{
public static string GetUrl<TRequest>(this AppHostBase appHostBase)
{
var requestType = typeof (TRequest);
return appHostBase.GetUrl(requestType);
}
public static string GetUrl(this AppHostBase appHostBase, Type requestType)
{
var endpointHostConfig = appHostBase.Config;
var serviceStackHandlerFactoryPath = endpointHostConfig.ServiceStackHandlerFactoryPath;
var serviceRoutes = appHostBase.Routes as ServiceRoutes;
if (serviceRoutes == null)
{
throw new NotSupportedException("Property Routes of AppHostBase is not of type ServiceStack.ServiceHost.ServiceRoutes");
}
var restPaths = serviceRoutes.RestPaths;
var restPath = restPaths.FirstOrDefault(arg => arg.RequestType == requestType);
if (restPath == null)
{
return null;
}
var path = restPath.Path;
var virtualPath = "~/" + string.Concat(serviceStackHandlerFactoryPath, path); // bad, i know, but combining with 2 virtual paths ...
var absolutePath = VirtualPathUtility.ToAbsolute(virtualPath);
return absolutePath;
}
}
I know that it is wrong because of many issues (path-combining, not taking rest-paths into account, not taking rest-paths with placeholders into account), but it works as a start ...
Edit:
And this only works, if you register the route within Configure(Container) of your AppHostBase-implementation. It wont't work with the RestServiceAttribute-attribute ...
