解决IE浏览器把application/json响应视为文件并尝试下载

下面我的解决方案是针对.net MVC的，其他的解决方案也类似，就是把响应的mimeType换成IE浏览器已经拥有的。如application/json换成text/plain

        #region 退出登录
        public ActionResult Logout()
        {
            ResponseModel response = new ResponseModel();
            try
            {
                _authenticationService.SignOut();
                response.StatusCode = 200;
                response.Message = "退出登录";
            }
            catch (Exception e)
            {
                response.StatusCode = 500;
                response.Message = e.Message;
            }
            return Json(response, "text/plain", Encoding.UTF8, JsonRequestBehavior.AllowGet);
        }
        #endregion
