메서드는 AJAX에서만 호출 할 수 없습니다.

나는 몇 시간 동안 인터넷에서 쓰레기를 검색했지만 이것이 작동하지 않는 이유를 파악하지 못했습니다.

사용자가 작성하고 양식을 작성하고 해당 양식을 데이터베이스에 간단하게 저장하기를 원합니다. 아약스를 넣기 전에는 완벽하게 작동했습니다. 하지만 이제는 계속 오류가 발생합니다.Sorry, this method can't be called only from AJAX.

여기 내 코드가 있습니다.

제어 장치:

// GET: /AjaxStuff/Create
        public ActionResult Contact()
        {
            return View();
        }

        // POST: /AjaxStuff/Create
        [HttpPost]
        public ActionResult Contact(Users usertocreate)
        {
            if (!Request.IsAjaxRequest())
            {
                Response.StatusCode = (int)System.Net.HttpStatusCode.BadRequest;
                return Content("Sorry, this method can't be called only from AJAX.");
            }
            try
            {
                if (ModelState.IsValid)
                {
                    _db.Table.Add(usertocreate);
                    _db.SaveChanges();
                    return Content("Record added successfully !");
                }
                else
                {
                    StringBuilder strB = new StringBuilder(500);
                    foreach (ModelState modelState in ModelState.Values)
                    {
                        foreach (ModelError error in modelState.Errors)
                        {
                            strB.Append(error.ErrorMessage + ".");
                        }
                    }
                    Response.StatusCode = (int)System.Net.HttpStatusCode.BadRequest;
                    return Content(strB.ToString());
                }
            }
            catch (Exception ee)
            {
                Response.StatusCode = (int)System.Net.HttpStatusCode.BadRequest;
                return Content("Sorry, an error occured." + ee.Message);
            }
        }
