$("#btnLoginApi").click(function () {
                $.ajax({
                    type: 'POST',
                    dataType: 'jsonp',
                    url: 'http://localhost:43157/api/values/',
                    data: "value=123"
                    contentType: "application/json; charset=utf-8",
                    success: function (result) {
                        alert(result);
                    },
                    error: function (XMLHttpRequest, textStatus, errorThrown) {
                        debugger;
                    }
                });
            });

ValuesController:

       // GET api/values        

[HttpGet]        

public IEnumerable<string> Get()         {      

       return new string[] { "value1", "value2" };      

   }

        // GET api/values/5        

public string Get(int id)        

{             return "value";         }

        // POST api/values        

[HttpPost]        

public string Post([FromBody]string value)        

{          return    value;       }

        // PUT api/values/5        

public void Put(int id, [FromBody]string value)         {         }

        // DELETE api/values/5        

public void Delete(int id)         {         }

为什么总是调用get方法，总是进不了post，请哪位大神指导一下？
