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 = ;
                 response.Message = "退出登录";
             }
             catch (Exception e)
             {
                 response.StatusCode = ;
                 response.Message = e.Message;
             }
             return Json(response, "text/plain", Encoding.UTF8, JsonRequestBehavior.AllowGet);
         }
         #endregion
