I'm new to Web API... Here's my basic route:
config.Routes.MapHttpRoute(
name: "Workitems",
routeTemplate: "api/{controller}/{workitemID}",
defaults: new { controller = "workitems", workitemID = RouteParameter.Optional }
);
Here's what I'd like to have:
public HttpResponseMessage Post( [FromBody] FolderModel theModel )
public HttpResponseMessage Post( [FromBody] DocumentModel theModel )
But, Web API doesn't find my second Post method. I've done lots of searching here and in Google but haven't found anything that works for me (well). I know I could add a 2nd unused parameter to the 2nd method - but that's too much of a hack. If this were normal C# code, the compiler would have no problem knowing which to choose b/c the methods have different signatures. But Web API is not smart enough.
I looked at custom constraints but that didn't seem appropriate. I also cannot use different {actions} as that violates RESTful constraints (no RPC, just resources) for my API. I also cannot put the 2nd Post on a different controller.
The only way I've gotten this to work is to wrap both FolderModel and DocumentModel in a parent object like this:
public class WorkitemCreateModel
{
public DocumentModel Document { get; set; }
public FolderModel Folder { get; set; }
}
public HttpResponseMessage Post( [FromBody] WorkitemCreateModel theModel )
Then have a single Post method that takes WorkitemCreateModel. But then it's the responsibility of the developer using my API that they must pass in WorkitemCreateModel but they must only pass in a DocumentModel object OR a FolderModel object. It's annoying too b/c my GET API can return either a DocumentModel object or a FolderModel object. So, it would be nice to just pass the object you get from the GET into the POST. But that doesn't work and they must wrap it in a WorkitemCreateModel object first.
Any other suggestions?
BTW: this website is the best! I've found SO many answers here!
