是否在 Blazor 应用程序中实施了访问被拒绝的路径

Question

Blazor 应用中是否有内置 AccessDeniedPath 功能。我的应用程序对某些组件使用基于角色的授权方法。例如 (@attribute [Authorize(Roles ="Admin")])
在我的 App.razor

<AuthorizeRouteView RouteData="@routeData" DefaultLayout="@typeof(MainLayout)">
    <NotAuthorized>
            <h1>Sorry</h1>
            <p>You're not authorized to reach this page.</p>
            <p>You may need to log in as a different user.</p>
    </NotAuthorized>
    <Authorizing>
        <h1>Authentication in progress</h1>
        <p>Only visible while authentication is in progress.</p>
    </Authorizing>
</AuthorizeRouteView>

属于 NotAuthorized 的请求是来自无权限用户还是匿名用户（根本未授权）。

有一个 context 可用于确定当前用户是否已通过身份验证。

例如：

<AuthorizeRouteView RouteData="@routeData" DefaultLayout="@typeof(MainLayout)" >
    <NotAuthorized>
        @if(!context.User.Identity.IsAuthenticated)
        {
            <p> You need Login! </p>  
        } else{
            <p> Sorry, the content here is not for you! </p> 
            @*or render or component like <AccessDenied /> directly *@
        }
    </NotAuthorized>
    <Authorizing>
        <h1>Authentication in progress</h1>
        <p>Only visible while authentication is in progress.</p>
    </Authorizing>
</AuthorizeRouteView>
