Question

我正在使用MongoDb数据库开发一个基于AngularJs和ASP.net MVC的小型Web应用程序。如果不是已经是会员，那么其中一项任务就是注册自己。在成功地将数据从客户端提交到服务器之后，用户应该被重定向到另一个页面。所以数据在提交后保存在数据库中但是它似乎没有触发Angular部分的成功功能，其中我尝试重定向到另一页。

我附上的图片显示了黄色突出显示的非触发部分代码。

我该如何解决这个问题？任何帮助将不胜感激。

 [HttpPost]
    public JsonResult RegisterUser(User user)
    {
        mongoClient = new MongoClient();
        var db = mongoClient.GetDatabase(Database);
        userList = db.GetCollection<User>("user");
        var result = userList.AsQueryable().Where(a => a.UserName.Equals(user.UserName)).SingleOrDefault();
        user.IsActive = true;
        user.UserType = "Visitor";
        string message = "";

        if (result == null)
        {
            var seralizedUser = JsonConvert.SerializeObject(userList);
            userList.InsertOne(user);
            //var seralizedUser = new JavaScriptSerializer().Serialize(userList);
            message = "Success";

            //return Json(seralizedUser, JsonRequestBehavior.AllowGet);
            return Json(new
            {
                redirectUrl = Url.Action("VisitorChatPanel", "Visitor", ""),
                isRedirect = true
            });

          //  return new JsonResult { Data = message, JsonRequestBehavior = JsonRequestBehavior.AllowGet };
        }
        else
        {
            message = "Failed";
            //var seralizedUser = new JavaScriptSerializer().Serialize(userList);
            var seralizedUser = JsonConvert.SerializeObject(userList);
         //   return Json(seralizedUser, JsonRequestBehavior.AllowGet);
                          return Json(new
            {
                redirectUrl = Url.Action("VisitorChatPanel", "Visitor", ""),
                isRedirect = false
            }); 

        }
