copied!<p>I have a simple Controller that is returning thumbnails, it is defined like:</p> <pre><code>public class ThumbnailsController : ApiController { public HttpResponseMessage Get(string id) { //code here } } </code></pre> <p>Everything works fine, I can access image using url <code>http://site.com/api/Thumbnails/mylogin</code></p> <p>But I would like to modify this method like so:</p> <pre><code>public class ThumbnailsController : ApiController { public HttpResponseMessage Get(string login="", int size=64) { //code here } } </code></pre> <p>Idea is to be able to call:<br/> - <code>http://site.com/api/Thumbnails/</code> - this will return current logged in user picture in default (64x64) size<br/> - <code>http://site.com/api/Thumbnails/mylogin</code> - this will return mylogin user picture in default (64x64) size<br/> - <code>http://site.com/api/Thumbnails/mylogin/128</code> - this will return mylogin user picture in 128x128 size</p> <p>My problem are routes, default route works with my unchanged method, but how should I change the default to get this working?</p> <p>I will also have other Api Controllers but only this one should have custom route.</p> <p>Here is my attempt, but it isn't working.</p> <pre><code>routes.MapHttpRoute( name: "Thumbnails", routeTemplate: "api/thumbnails/{login}/{size}", defaults: new {controller="Thumbnails", action="Get", login = RouteParameter.Optional, size = RouteParameter.Optional } ); </code></pre> <p><strong>EDIT</strong> This is my Controller with test method:</p> <pre><code>public class ThumbnailsController : ApiController { public string Get(string login="", int size=64) { return string.Format("login: {0}, size: {1}", login, size); } } </code></pre> <p>and here is my RouteConfig:</p> <pre><code>public class RouteConfig { public static void RegisterRoutes(RouteCollection routes) { routes.IgnoreRoute("{resource}.axd/{*pathInfo}"); routes.MapRoute( name: "Default", url: "{controller}/{action}/{id}", defaults: new {controller = "Home", action = "Index", id = UrlParameter.Optional} ); routes.MapHttpRoute( name: "Thumbnails", routeTemplate: "api/Thumbnails/{login}/{size}", defaults: new { controller = "Thumbnails" , login = RouteParameter.Optional, size = RouteParameter.Optional } ); } } </code></pre>
