  Explicitly declaring UriTemplate

  Nov 07, 2012 11:49 PM|LINK

  Hi there.  There are particular cases where you might need to create some sort of custom route for a particular service.  Simply assume you have a Category and the Category has a single property of type CategorySubResource and another property of type Category.  How can I do the following?
  
  Code I want to perform.  
  public class CategoriesService : ApiController{

          public IEnumerable<Category> GetAll(){  return ... } // great...  This returns the list of them
          public Category GetCategory(string id){ return .... } // great....  This returns a single category 
          public CategorySubResource GetCategorySubResource(string id) { ... } // Runtime exception... ???
          public Category GetParentCategory(string id) { ... } // ???
  } 

  Routing code:
   config.Routes.MapHttpRoute(
  name: "DefaultApi",
  routeTemplate: "api/{controller}/{id}",
  defaults: new { id = RouteParameter.Optional });

  When I had the ability to explicitly put [WebGet] and [WebInvoke] attributes on my methods in version 0.6.0 (WCF WebApi) this was a very simple thing...  Now, how can I do this?

  Thanks everyone in advance!

  Here is the example class I am working with.

  public class CategoriesController : ApiController
  {
  public static IEnumerable<Category> Categories = new List<Category>()
  {
  new Category(){ Id = "1", Description = "something here " + Guid.NewGuid().ToString(), Name = "Some Name " + Guid.NewGuid().ToString(), ParentId = null},
  new Category(){ Id = "2", Description = "something here " + Guid.NewGuid().ToString(), Name = "Some Name " + Guid.NewGuid().ToString(), ParentId = null},
  new Category(){ Id = "3", Description = "something here " + Guid.NewGuid().ToString(), Name = "Some Name " + Guid.NewGuid().ToString(), ParentId = null},
  new Category(){
  Id = "4",
  Description = "something here " + Guid.NewGuid().ToString(),
  Name = "Some Name " + Guid.NewGuid().ToString(),
  ParentId = null,
  SomethingElse = new SomethingElse(){ Id = "5", Name = "ASDFASDF"},
  Child = new Category{ Id = "7", Description = "something here " + Guid.NewGuid().ToString(), Name = "Some Name " + Guid.NewGuid().ToString(), ParentId = null}
  }
  };

  public IEnumerable<Category> GetAll()
  {
  return Categories;
  }

  public Category Get(string id)
  {
  return Categories.FirstOrDefault(d => d.Id == id);
  }
  
  public SomethingElse GetSomethingElse(string id)
  {
  var item = Categories.FirstOrDefault(d => d.Id == id);
  if (item != null)
  return item.SomethingElse;
  return null;
  }

  public Category GetChild(string parentId)
  {
  var item = Categories.FirstOrDefault(d => d.Id == parentId);
  if (item != null)
  return item.Child;
  return null;
  }
  }

  you could change your route to the following and explicitly supply the name of the action in your request url:

  config.Routes.MapHttpRoute(
  name: "DefaultApi",
  routeTemplate: "api/{controller}/{action}/{id}",
  defaults: new { id = RouteParameter.Optional });

  Thanks,
