Configure ServiceStack Base URI URIs

Question

I am creating a self-service REST service using the service stack and AppHostHttpListenerBase. I would like to use the base URI for my services (e.g. api):

http://myserver/api/service1/param http://myserver/api/service2/param 

How can I do this without defining an “api” on each of my routes. In IIS, I can set up a virtual directory to isolate services, but how do I do this in self-service?

Answer 1

ServiceStack HttpListener hosts assume that the root / path will be hosted, as a normal use case should be for each self-service service to be available on different user ports.

Since it does not support hosting in / custompath, you will need to specify the /api/ prefix on all your service routes.

Add a problem if you want to see hosting support on custom paths.

Here ya go .. (as a bonus, this is how you put your service in the plugin.

 using BlogEngineService; using ServiceStack.WebHost.Endpoints; using System; using System.Collections.Generic; using System.Linq; using System.Text; namespace BlogEngineWinService { public class AppHost : AppHostHttpListenerBase { public AppHost() : base("Self Host Service", typeof(AppHost).Assembly) { } public override void Configure(Funq.Container container) { Plugins.Add(new BlogEngine()); } } } 

Here's how you auto-install it

Call appHost.Routes.AddFromAssembly2(typeof(HelloService).Assembly); What causes the extension for automatic posting.

 using ServiceStack.WebHost.Endpoints; using System; using System.Collections.Generic; using System.Linq; using System.Text; using ServiceStack.ServiceInterface; namespace BlogEngineService { public class BlogEngine : IPlugin, IPreInitPlugin { public void Register(IAppHost appHost) { appHost.RegisterService<HelloService>(); appHost.Routes.AddFromAssembly2(typeof(HelloService).Assembly); } public void Configure(IAppHost appHost) { } } } 

This is how you tag a service class to give it a prefix. Just mark the class using this attribute

 using ServiceStack.DataAnnotations; using ServiceStack.ServiceHost; using ServiceStack.ServiceInterface; using System; using System.Collections.Generic; using System.Linq; using System.Text; namespace BlogEngineService { public class Hello { [PrimaryKey] public string Bob { get; set; } } public class HelloResponse { public string Result { get; set; } } [PrefixedRoute("/test")] public class HelloService : Service { public object Any(Hello request) { return new HelloResponse { Result = "Hello, " + request.Bob}; } } } 

Create a CS file in the project for extension ..

 using System; using System.Collections.Generic; using System.Linq; using System.Linq.Expressions; using System.Reflection; using ServiceStack.Common; using ServiceStack.Common.Utils; using ServiceStack.Common.Web; using ServiceStack.Text; using ServiceStack.ServiceHost; using ServiceStack.WebHost.Endpoints; using ServiceStack.ServiceInterface; namespace ServiceStack.ServiceInterface { public static class ServiceRoutesExtensions { /// <summary> /// Scans the supplied Assemblies to infer REST paths and HTTP verbs. /// </summary> ///<param name="routes">The <see cref="IServiceRoutes"/> instance.</param> ///<param name="assembliesWithServices"> /// The assemblies with REST services. /// </param> /// <returns>The same <see cref="IServiceRoutes"/> instance; /// never <see langword="null"/>.</returns> public static IServiceRoutes AddFromAssembly2(this IServiceRoutes routes, params Assembly[] assembliesWithServices) { foreach (Assembly assembly in assembliesWithServices) { AddNewApiRoutes(routes, assembly); } return routes; } private static void AddNewApiRoutes(IServiceRoutes routes, Assembly assembly) { var services = assembly.GetExportedTypes() .Where(t => !t.IsAbstract && t.HasInterface(typeof(IService))); foreach (Type service in services) { var allServiceActions = service.GetActions(); foreach (var requestDtoActions in allServiceActions.GroupBy(x => x.GetParameters()[0].ParameterType)) { var requestType = requestDtoActions.Key; var hasWildcard = requestDtoActions.Any(x => x.Name.EqualsIgnoreCase(ActionContext.AnyAction)); string allowedVerbs = null; //null == All Routes if (!hasWildcard) { var allowedMethods = new List<string>(); foreach (var action in requestDtoActions) { allowedMethods.Add(action.Name.ToUpper()); } if (allowedMethods.Count == 0) continue; allowedVerbs = string.Join(" ", allowedMethods.ToArray()); } if (service.HasAttribute<PrefixedRouteAttribute>()) { string prefix = ""; PrefixedRouteAttribute a = (PrefixedRouteAttribute)Attribute.GetCustomAttribute(service, typeof(PrefixedRouteAttribute)); if (a.HasPrefix()) { prefix = a.GetPrefix(); } routes.AddRoute(requestType, allowedVerbs, prefix); } else { routes.AddRoute(requestType, allowedVerbs); } } } } private static void AddRoute(this IServiceRoutes routes, Type requestType, string allowedVerbs, string prefix = "") { var newRoutes = new ServiceStack.ServiceHost.ServiceRoutes(); foreach (var strategy in EndpointHost.Config.RouteNamingConventions) { strategy(newRoutes, requestType, allowedVerbs); } foreach (var item in newRoutes.RestPaths) { string path = item.Path; if (!string.IsNullOrWhiteSpace(prefix)) { path = prefix + path; } routes.Add(requestType, restPath: path, verbs: allowedVerbs); } } } public class PrefixedRouteAttribute : Attribute { private string _prefix { get; set; } private bool _hasPrefix { get; set; } public PrefixedRouteAttribute(string path) { if (!string.IsNullOrWhiteSpace(path)) { this._hasPrefix = true; this._prefix = path; //this.Path = string.Format("/{0}{1}", Prefix, Path); } } public bool HasPrefix() { return this._hasPrefix; } public string GetPrefix() { return this._prefix; } } } 

Answer 3

Actually there is a simpler solution. In your web.config, update your http handler to:

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

With the above, all of your utility apis must have the prefix "/ api /". If you have already used "/ api /" on any of your routes, you should delete them or specify them twice in your calls.

I found a workaround for this. I tested this only with self-hosting.

Create a PrefixedRouteAttribute class that inherits from RouteAttribute

 public class PrefixedRouteAttribute : RouteAttribute { public static string Prefix { get; set; } public PrefixedRouteAttribute(string path) : base(path) { SetPrefix(); } public PrefixedRouteAttribute(string path, string verbs) : base(path, verbs) { SetPrefix(); } private void SetPrefix() { if (!string.IsNullOrWhiteSpace(Prefix)) { this.Path = string.Format("/{0}{1}", Prefix, Path); } } } 

When creating AppHost, you can set the prefix

 PrefixedRouteAttribute.Prefix = "api"; 

Then, instead of using the [Route] attribute, use the [Route Prefix] attribute in your classes

 [PrefixedRoute("/echo")] [PrefixedRoute("/echo/{Value*}")] public class Echo { [DataMember] public string Value { get; set; } } 

This will work for queries

 /api/echo /api/echo/1 

It can be improved. I do not really like the way I need to set the prefix through the static property, but I could not come up with a more suitable approach in my setup. The principle of creating an overriding attribute seems sound, though, and this is an important part.
