Web API发布正文对象为null

Question

I have a Web api method like this

        [HttpPost]
        public IHttpActionResult Login(ILogin request)
        {
             // do stuff 
        }

My Login object is

 public interface ILogin 
    {
        string UserName { get; set; }
        string Password { get; set; }
    }

I am trying to call from fiddler with the following details

url - myapi.com/login

Request Body

  { "UserName": "ingridmooney@insurity.com", "Password": "adfdfdf" } 

I tried various combinations of request body - but whenever i debug - the ILogin request is always null. What am i doing wrong?

You can't instantiate an interface. Your webapi should expect a class that implements the ILogin interface.
