post request with manual parameters

There is a method in the controller:

[HttpPost] [ValidateAntiForgeryToken] //public async Task<Users> Post([FromBody] Users user) - тоже пробовал public async Task<Users> Post([Bind(Include = "id,FIO,login,password,date_for_last_sign_in")] Users user) { return user; } 

model:

 using System; using System.Collections.Generic; using System.Linq; using System.Web; namespace WebApplication2.Models { public class Users { public int id { get; set; } public string FIO { get; set; } public string login { get; set; } public string password { get; set; } public DateTime date_for_last_sign_in { get; set; } } } 

Question: how to check the functionality of the function?

I created a button and try this:

 $(document).ready(function () { $("#addUser").click(function () { var users = { id: 1, FIO: "fio", login: "log", password: "pass", date_for_last_sign_in: "2012-04-23T18:25:43" }; $.ajax({ url: '/api/values/', type: 'POST', data: JSON.stringify(users), contentType: "application/json;charset=utf-8", success: function (data) { alert(data); }, error: function () { alert("error");} }); }); }); 

I get an empty object, why so?
