您好我在尝试使用 Ajax 的 Web API 控制器发布/放置/删除对象时遇到问题。无论我尝试什么，我的Hello对象都是 Post/Put as 。id = 0hello = null

我正在做的任何事情都会导致这种行为？

//ServicingController.cs
using System.Collections.Generic;
using System.Diagnostics;
using System.Web.Http;

namespace ServicingWebApi.Api
{
    public class ServicingController : ApiController
    {
        public class Hello
        {
            public int id { get; set; }
            public string hello { get; set; }

            public override string ToString()
            {
                return string.Format("id: {0}, hello {1}", id, hello);
            }
        }

        // GET api/<controller>
        public IEnumerable<string> Get()
        {
            return new[] { "value1", "value2" };
        }

        // GET api/<controller>/5
        public string Get(int id)
        {
            return "value";
        }

        // POST api/<controller>
        public void Post(Hello stuff)
        {
            Debug.Write(stuff.ToString());
        }

        // PUT api/<controller>/5
        public void Put(int id, Hello stuff)
        {
            Debug.Write(stuff.ToString());
        }

        // DELETE api/<controller>/5
        public void Delete(int id)
        {
            Debug.Write(string.Format("Deleted id: {0}", id));
        }
    }
}

试试这种数据格式

var data = JSON.stringify({ id: 1, hello: "World" });
