Orchardcms 如何使Orchard CMS使用AntiForgeryToken？

使用Orchard CMS 1.4.2，我在自定义模块中发布表单时遇到问题

以下是我的看法：

@model ProfileEntity

<h2>My Profile</h2>

@using (Html.BeginForm("Update", "Home", FormMethod.Post))
{
    @Html.AntiForgeryToken()

    @Html.LabelFor(m => m.FirstName)
    @Html.EditorFor(m => m.FirstName)

    @Html.LabelFor(m => m.MiddleNames)
    @Html.EditorFor(m => m.MiddleNames)

    @Html.LabelFor(m => m.Surname)
    @Html.EditorFor(m => m.Surname)

    <input type="submit" value="Save Profile"/> 
}

当我尝试发布此表单时，我遇到一个例外：

[HttpAntiForgeryException (0x80004005): A required anti-forgery token was not supplied or was invalid.]
   System.Web.Helpers.AntiForgeryWorker.Validate(HttpContextBase context, String salt) +121176

   System.Web.HttpApplication.ExecuteStep(IExecutionStep step, Boolean& completedSynchronously) +184

而不是

@Html.AntiForgeryToken()

（我不确定有什么区别）

但是它给出了同样的错误。

看看现有模块代码中几十个示例中的一个

@using (Html.BeginFormAntiForgeryPost())

@Html.AntiForgeryToken()

@using (Html.BeginFormAntiForgeryPost())
