  Multiple HttpPost method in MVC4 Web API Controller

  Jul 10, 2012 06:10 AM|LINK

  I am starting to use MVC4 Web API project, I have controller with multiple 

  HttpPost

   methods. The Controller looks like the following:

  Controller

  public class VTRoutingController : ApiController
      {
   [HttpPost]
          public MyResult Route(MyRequestTemplate routingRequestTemplate)
          {
              return null;
          }
  
   [HttpPost]
          public MyResult TSPRoute(MyRequestTemplate routingRequestTemplate)
          {
            return null;
          }
     }
  

  Here 

  MyRequestTemplate

   represents the template class responsible for handling the Json coming through the request.

  Error:

  When I make a request using Fiddler for 

  http://localhost:52370/api/VTRouting/TSPRoute

   or

  http://localhost:52370/api/VTRouting/Route

   I get an error:

  Multiple actions were found that match the request

  If I remove one of the above method it works fine

  global.asax

  I have tried modifying the default routing table in 

  global.asax

  , but I am still getting the error, I think I have problem in defining routes in global.asax. Here is what I am doing in global.asax.

  public static void RegisterRoutes(RouteCollection routes)
  {
      routes.MapHttpRoute(
              name: "MyTSPRoute",
              routeTemplate: "api/VTRouting/TSPRoute",
              defaults: new { }
  
    );
  
      routes.MapHttpRoute(
          name: "MyRoute",
          routeTemplate: "api/VTRouting/Route",
          defaults: new {action="Route" }
  
  );
  }
  

  I am making the request in Fiddler using POST, passing json in RequestBody for MyRequestTemplate

  Change your routing to include {action} in the route template. The default should work:

  routes.MapHttpRoute(
      name: "API Default",
      routeTemplate: "api/{controller}/{action}/{id}",
      defaults: new { id = RouteParameter.Optional }
  );
