使用 ReuseTabs 组件时，通过级联传入 RouteData 的方式会导致 AuthorizeRouteView 失效。

操作步骤:

1.使用 dotnet new antdesign -o MyAntDesignAppSimple 创建模板
2.添加文件 PersistingRevalidatingAuthenticationStateProvider

internal sealed class PersistingRevalidatingAuthenticationStateProvider : AuthenticationStateProvider
{

    public override Task<AuthenticationState> GetAuthenticationStateAsync()
    {
        //var cI = new ClaimsIdentity("test");
        //cI.AddClaim(new Claim(ClaimTypes.Name, "admin"));
        //cI.AddClaim(new Claim(ClaimTypes.Email, "admin@test"));

        //var cP = new ClaimsPrincipal(cI);
        //var state = new AuthenticationState(cP);
        //var task = Task.FromResult(state);
        //NotifyAuthenticationStateChanged(task);
        //return task;
        return Task.FromResult(new AuthenticationState(new ClaimsPrincipal()));
    }
}

3. 在MyAntDesignAppSimple .Program.cs中添加以下内容

builder.Services.AddCascadingAuthenticationState();
builder.Services.AddScoped<AuthenticationStateProvider, PersistingRevalidatingAuthenticationStateProvider>();

4. 添加一个需要权限的页面

@page "/counter"
@using Microsoft.AspNetCore.Authorization
@attribute [Authorize]
<PageTitle>Counter</PageTitle>

<h1>Counter</h1>
<AuthorizeView>
    <NotAuthorized>没权限</NotAuthorized>
    <Authorized>有权限Hello @context.User.Identity?.IsAuthenticated.ToString();</Authorized>

</AuthorizeView>

<p role="status">Current count: @currentCount</p>

<button class="btn btn-primary" @onclick="IncrementCount">Click me</button>

@code {
    private int currentCount = 0;

    private void IncrementCount()
    {
        currentCount++;
    }
}

5. 将Routes文件替换为以下内容

<Router AppAssembly="typeof(Program).Assembly">
    <Found Context="routeData">
        <CascadingValue Value="routeData">
            <AuthorizeRouteView RouteData="@routeData"  DefaultLayout="@typeof(Layouts.BasicLayout)">
                <NotAuthorized>
                    没权限路由
                </NotAuthorized>
            </AuthorizeRouteView>
        </CascadingValue>
        <FocusOnNavigate RouteData="routeData" Selector="h1" />
    </Found>
</Router>

<AntContainer />

结果依旧可以导航到该页面

后续

注释包裹AuthorizeRouteView 的CascadingValue，并向 ReuseTabs 组件传入 Body 参数后恢复正常
