Question

我可以设置从提交未执行控制器的表单加载的用户的身份验证状态。加载主页时，一切都正常工作（SuccessfullyLogged），但是当我提交表单时，View被加载但只有View和控制器没有被执行而我得到SuccessfullyLogged = false：

编辑：

页面结构为：

<Layout>
   <Login Header Partial View>  
        @{ Html.RenderAction(MVC.Account.LoginHeader()); } 
   </Login Header Partial View>
   <Body>
        @RenderBody() <-- GetAllByCategory.cshtml rendered inside of it
   </Body>
</Layout>

流程的逻辑：

CategoryGetAllBySearch.cshtml --> Controller GetAllByIds -> View GetAllByCategory inside of the Layout

编辑：

登录标题的布局上下文：

<!-- Login button -->
<ul class="menudrt" id="headerLogin">
    @{ Html.RenderAction(MVC.Account.LoginHeader()); }
</ul>
<!---->

登录标题视图：

@model Heelp.ViewModels.LoginViewModel

<input type="hidden" id="IsUserAuthenticated" value="@Model.SuccessfullyLogged.ToString()" />

登录标题控制器：

[AllowAnonymous]
public virtual PartialViewResult LoginHeader()
{
    var model = new LoginViewModel();

    if (WebSecurity.IsAuthenticated)
    {
        model.SuccessfullyLogged = true;
    }
    else
        model.SuccessfullyLogged = false;

    return PartialView(model);
}

使用提交的表单查看CategoryGetAllBySearch.cshtml：

@model Heelp.ViewModels.CategoryGetAllBySearchListViewModel

@if (@Model.TotalSearchCount == 0)
{
    <p>lamentamos mas não foram encontrados resultados para a sua pesquisa<br />
        sugestões: <br />
        &nbsp;&nbsp;» veja a lista de carros, motos ou comerciais a partir do menu<br />
        &nbsp;&nbsp;» tente utilizar outras ou menos palavras</p>
}
else
{
    <p>encontrámos <strong style="font-style:italic;">@Model.TotalSearchCount</strong> resultado(s) na(s) categoria(s):</p><!-- total results main text -->

    foreach (var item in Model.CategoryGetAllBySearch)
    {
    @using (Html.BeginForm("GetAllByIds", "Ads", FormMethod.Post, new { id = "homeCategoryForm_" + item.Id }))
    {
        @Html.AntiForgeryToken()

        @Html.Hidden("ids", string.Join("-", item.Ids))
        @Html.Hidden("categoryId", item.Id)
        @Html.Hidden("search", (string)ViewBag.search)
        @Html.Hidden("location", (string)ViewBag.location)
    }

        <div id="category_@item.Id" class="innerelement">
            <p id="category-p_@item.Id"><strong style="font-style:italic;">@Html.DisplayFor(modelItem => item.SearchCount)</strong> @Html.DisplayFor(modelItem => item.Name)<span>ver</span></p>
            <img id="category-img_@item.Id" src="~/Content/Images/ui-symb-arrow-right-green-12x12.png" width="12" height="12" />
        </div>  
    }        
}

此形式的控制器GetAllByIds：

[HttpPost]
[AllowAnonymous]
[ValidateAntiForgeryToken]
public virtual ActionResult GetAllByIds(string ids, int categoryId, string search, string location)
{
    AdGetAllByCategoryListViewModel model = new AdGetAllByCategoryListViewModel();

    model.Ads = Mapper.Map<IList<AdGetAllByCategoryDto>, IList<AdGetAllByCategoryViewModel>>(_adService.GetAllByIds(ids));

    model.Category = Mapper.Map<CategoryDto, CategoryViewModel>(_categoryService.GetById(categoryId));

    return View(MVC.Ad.Views.GetAllByCategory, model);
}

那么为什么表单提交时没有调用控制器/视图而只调用视图？

在@Racil Hilan的帮助下进行了一些测试后，我在这里找到了问题。

问题在于我有两个名为LoginHeader的动作，一个具有[HttpPost]属性，另一个没有它。

[AllowAnonymous]
public virtual PartialViewResult LoginHeader()
{
    var model = new LoginViewModel();

    if (WebSecurity.IsAuthenticated)
    {
        model.SuccessfullyLogged = true;

        MemberDto memberDto = _memberService.GetMemberById(WebSecurity.CurrentUserId);
        model.MemberType_Id = memberDto.MemberType_Id;
    }
    else
        model.SuccessfullyLogged = false;

    return PartialView(model);
}

[HttpPost]
[AllowAnonymous]
[ValidateAntiForgeryToken]
public virtual PartialViewResult LoginHeader(LoginViewModel model, string returnUrl)
{
    if (ModelState.IsValid && WebSecurity.Login(model.Email, model.Password, persistCookie: model.RememberMe))
    {
        // The user is valid so it will be redirected based on the returnUrl. If null it will return to the Home-Page
        model.SuccessfullyLogged = true;
        model.Result = @HeelpResources.AccountLoginViewAutenticationValidMsg;
    }
    else
    {
        // Invalid credentials, so the user will have to try again
        model.SuccessfullyLogged = false;
        model.Result = @HeelpResources.AccountLoginViewAutenticationInvalidMsg;
    }

    return PartialView(model);
}

在这种情况下，当Post提交表单时，系统会进入标有[HttpPost]的表单，并且没有进行正确的验证。

所以建议是，当你使用两个同名的动作时要非常小心，因为系统可能会调用你不期望的那个。

MVC视图加载而不调用控制器
