asp.net-core - 从 razor 组件到 razor 页面的 aspnetcore blazor 导航

Question

我正在尝试从 razor 组件重定向到 razor 页面。如果用户未获得授权，我想从当前的 Razor 组件重定向到登录 Razor 页面。

我已经重定向到登录组件

public class RedirectToLogin : ComponentBase
    {
        [Inject]
        protected NavigationManager NavigationManager { get; set; }

        protected override void OnInitialized()
        {
            NavigationManager.NavigateTo("./Identity/Account/Login",true);
        }
    }

此行抛出错误 NavigationManager.NavigateTo("./Identity/Account/Login");

Microsoft.AspNetCore.Components.NavigationException:“引发了‘Microsoft.AspNetCore.Components.NavigationException’类型的异常。”

我的假设是问题出在从 Razor 组件到 Razor 页面的路由。

我使用下面的 Router 重定向到一个未授权的页面。

<Router AppAssembly="@typeof(Program).Assembly">
    <Found Context="routeData">
        <AuthorizeRouteView  RouteData="@routeData" DefaultLayout="@typeof(MainLayout)">
            <NotAuthorized>
                <div class="container">
            <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>
            <a href="Identity/Account/Login">Log in</a>
        </div>
                @*<RedirectToLogin />*@
            </NotAuthorized>
            <Authorizing>
                <div class="container">
                    <h1>Authentication in progress</h1>
                    <p>Leave your hands on the keyboard,  scanning your fingerprints.  Ain't technology grand.</p>
                </div>
            </Authorizing>
        </AuthorizeRouteView>
    </Found>
    <NotFound>
        <CascadingAuthenticationState>
            <LayoutView Layout="@typeof(MainLayout)">
                <p>Sorry, there's nothing at this address.</p>
            </LayoutView>
        </CascadingAuthenticationState>
    </NotFound>
</Router>

这对现在的应用来说已经足够了。
