在HTTPS上设置站点后，子操作不允许执行redirect操作

我得到下面的错误：

Child actions are not allowed to perform redirect actions. Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code. Exception Details: System.InvalidOperationException: Child actions are not allowed to perform redirect actions.

RenderAction.ascx代码，我得到第2行的错误是：

  <%@ Control Language="C#" Inherits="System.Web.Mvc.ViewUserControl<RenderActionViewModel>" %> <%Html.RenderAction(Model.ActionName, Model.ControllerName, Model.RouteValues); %> 

控制器中的Action是：

 public ViewResult DashboardQuicksearch(UserFilter userFilter, bool? showAdvancedSearchLink) { int resultCount; List<KeyInfo<string>> makeList = quickSearchProvider.GetKeysForCriteriaKey(SearchType.Vehicle, "MakeName", userFilter, "null", false, null, out resultCount); var selectListItems = new List<SelectListItem>(); foreach (KeyInfo<string> item in makeList) { selectListItems.Add(new SelectListItem() { Text = item.Key, Value = item.Key, Selected = false }); } var viewModel = new DashboardQuicksearchViewModel() { MakeList = (makeList.Count == 1) ? new SelectList(selectListItems, "Value", "Text", selectListItems[0].Value) : new SelectList(selectListItems, "Value", "Text"), VehicleCount = quickSearchProvider.GetLotItemCount("null", userFilter), ShowAdvancedSearchLink = (showAdvancedSearchLink.HasValue ? showAdvancedSearchLink.Value : false) }; return View(Constants.Views.Search.DashboardQuicksearch, viewModel); } 

我绝对不知道如何解决这个问题。

编辑：

这是DashboardQuickSearch.ascx

Answer 1

这意味着：

1. 已经处理了该URL对应的操作，并返回了查看结果。
2. ASP.NET MVC的视图引擎已经开始渲染视图，可能会将头部和HTML的一部分发送给浏览器。
3. 视图引擎遇到了RenderAction（…）调用，并开始执行该操作。
4. 该操作尝试将redirectHTTP状态码返回给浏览器

在这一点上，ASP.NET不知所措：它已经开始向客户端发送头文件和HTML，但是现在突然被告知要回收所有这些，而是​​发送一个redirect状态代码。 显然不能这样做，所以会引发exception。

你将不得不弄清为什么redirect被触发，并确保不会发生。 最可能的原因（但绝不是唯一可能的原因）是一些自定义的操作filter，没有被devise为考虑到孩子的行为。 ASP.NET MVC操作筛选器通常会检查执行的操作是否被调用为子操作，并避免在这种情况下redirect。

Answer 2

你应该写return PartialView(...)而不是return View(...)一个childAction的return View(...) 。

Answer 3

问题是ControllerBase类中的ActionFilter。 （我第一次没有看到）

它就像

 [ActionFilters.RequireHttps(RequireSecure = false)] 

必须将其设置为“真”

谢谢大家的回答。
