Route to different actions based on json value

Question

I would like to route requests to different actions based on the value of a particular json parameter.

For example, given the following json data:

Answer 1

Something like this. For simplicity, this example is not a proper async implementation.

using System.Net.Http;
using System.Web.Http;

namespace MyApi.Controllers
{
    public class MyType {
        public string type {get; set;}
    }

    public class MyType1 {
        public string type {get; set;}
        public string type1data {get; set;}
    }

    public class MyType2 {
        public string type {get; set;}
        public string type2data {get; set;}
    }

    public class ObjectsController : ApiController {

        //
        // api/objects/create
        //
        public void Create() {
            // buffer the content to allow the dual reads below
            Request.Content.LoadIntoBufferAsync().Wait();

            // get the body as a object so we can access its type property
            MyType postedObject = Request.Content.ReadAsAsync().Result;

            // decide
            switch (postedObject.type) {
                case "type1":
                    CreateType1(Request.Content.ReadAsAsync().Result.type1data);
                    break;
                case "type2":
                    CreateType2(Request.Content.ReadAsAsync().Result.type2data);
                    break;
                default:
                    // 400 Bad Request would be best, I think.
                    break;
            }
        }

        private void CreateType1(string type1data) {
            // ... 
        }

        private void CreateType2(string type2data) {
            // ...
        }
    }
}
