What's wrong with this route

Question

Given the following:

namespace Foo.Controllers
{
    [RoutePrefix("api/route")]
    public class SnoconesFooBarController : BaseApiController
    {
        /// <summary>
        /// Asks for a new foo to be created to the given subnet with the specific bar named
        /// </summary>
        /// <param name="fooName"></param>
        /// <param name="uriString"></param>
        /// <returns></returns>
        [Route("newFoo/{fooName}")]
        public async Task<IHttpActionResult> PostNewFooForSpecificBar(string fooName, string uriString)
        {
        }
}

Why do I get a 404 when I try to post to:

http://localhost:4471/api/route/newFoo/test1

with the following payload:

"http://127.0.0.1"

Answer 1

FWIW, I fixed it by changing it to look like this:

 namespace Foo.Controllers
{
    [RoutePrefix("api/route")]
    public class SnoconesFooBarController : BaseApiController
    {
        /// <summary>
        /// Asks for a new foo to be created to the given subnet with the specific bar named
        /// </summary>
        /// <param name="fooData"></param>
        /// <returns></returns>
        [Route("newFoo/")]
        public async Task<IHttpActionResult> PostNewFooForSpecificBar(FooRequestObject fooData)
        {
        }
}

And including all of the data I needed in the FooRequestObject
