copied!<p>You are very right. Self host returns IHttpRoute and takes HttpMessageHandler as a parameter. There seems no inbuilt way to specificity a route handler.</p> <p><strong>Update: To be a bit clearer</strong></p> <p>You should almost certainly have a go at using a HttpControllerSelector and implementing a custom one... An example being. <a href="http://netmvc.blogspot.co.uk/" rel="noreferrer">http://netmvc.blogspot.co.uk/</a></p> <p><strong>What follows is a bit of experimentation</strong> if the HttpControllerSelector is not sufficent for your requirements for what ever reason...</p> <p>But, as you can see the <code>MapHttpRoute</code> does have an overload for <code>HttpMessageHandler</code> so you can experiment with this... <a href="http://msdn.microsoft.com/en-us/library/system.web.http.routing.ihttproute.handler%28v=vs.108%29.aspx" rel="noreferrer">if the handler is NULL then it defaults to IHttpController</a> but you can implement your own and use this to direct to the correct controller... The MVC framework appears to use <code>[HttpControllerDispatcher]</code> <a href="http://aspnetwebstack.codeplex.com/SourceControl/changeset/view/f59892797e46#src/System.Web.Http/Dispatcher/HttpControllerDispatcher.cs" rel="noreferrer">here</a>, so borrowing some code you can place your own controller / route selection code here too - you have access to the route and selector and can swap it in and out yourself.</p> <p>This CustomHttpControllerDispatcher code is for DEMO only... look for the line </p> <blockquote> <p>//DO SOMETHING CUSTOM HERE TO PICK YOUR CONTROLLER</p> </blockquote> <p>And perhaps have a play with that...</p> <p><strong>Example route:</strong></p> <pre><code> config.Routes.MapHttpRoute( name: "DefaultApi", routeTemplate: "api/{controller}/{id}", defaults: new { id = RouteParameter.Optional }, constraints: null, handler: new CustomHttpControllerDispatcher(config) ); </code></pre> <p><strong>Example CustomHttpControllerDispatcher:</strong></p> <pre><code>public class CustomHttpControllerDispatcher : HttpMessageHandler { private IHttpControllerSelector _controllerSelector; private readonly HttpConfiguration _configuration; public CustomHttpControllerDispatcher(HttpConfiguration configuration) { _configuration = configuration; } public HttpConfiguration Configuration { get { return _configuration; } } private IHttpControllerSelector ControllerSelector { get { if (_controllerSelector == null) { _controllerSelector = _configuration.Services.GetHttpControllerSelector(); } return _controllerSelector; } } protected override Task<HttpResponseMessage> SendAsync(HttpRequestMessage request, CancellationToken cancellationToken) { return SendAsyncInternal(request, cancellationToken); } private Task<HttpResponseMessage> SendAsyncInternal(HttpRequestMessage request, CancellationToken cancellationToken) { IHttpRouteData routeData = request.GetRouteData(); Contract.Assert(routeData != null); //DO SOMETHING CUSTOM HERE TO PICK YOUR CONTROLLER HttpControllerDescriptor httpControllerDescriptor = ControllerSelector.SelectController(request); IHttpController httpController = httpControllerDescriptor.CreateController(request); // Create context HttpControllerContext controllerContext = new HttpControllerContext(_configuration, routeData, request); controllerContext.Controller = httpController; controllerContext.ControllerDescriptor = httpControllerDescriptor; return httpController.ExecuteAsync(controllerContext, cancellationToken); } } </code></pre>
