我已经创建了一个名为CustomAuthenticationStateProvider的类，它继承自身份验证状态提供程序。现在它是测试的基础，但我将在稍后从本地存储中的JWT读取它以进行声明。
代码如下：

public class CustomAuthenticationStateProvider : AuthenticationStateProvider
{
    private ClaimsPrincipal _anonymous = new ClaimsPrincipal(new ClaimsIdentity());

    private ClaimsPrincipal _user = new ClaimsPrincipal(new ClaimsIdentity());

    public override Task<AuthenticationState> GetAuthenticationStateAsync()
    {
        return Task.FromResult(new AuthenticationState(_user));
    }

    public void Login()
    {
        //make claims for an admin user and return that as the authentication state
        var claims = new List<Claim>
        {
            new Claim(ClaimTypes.Name, "Jeff"),
            new Claim(ClaimTypes.Role, "Admin")
        };

        var identity = new ClaimsIdentity(claims, "Custom");

        _user = new ClaimsPrincipal(identity);

        NotifyAuthenticationStateChanged(GetAuthenticationStateAsync());
    }

    public void Logout()
    {
        _user = _anonymous;

        NotifyAuthenticationStateChanged(GetAuthenticationStateAsync());
    }

Here is my app.剃刀

<CascadingAuthenticationState>
    <Router AppAssembly="@typeof(App).Assembly">
        <Found Context="routeData">
            <RouteView RouteData="@routeData" DefaultLayout="@typeof(MainLayout)" />
            <FocusOnNavigate RouteData="@routeData" Selector="h1" />
        </Found>
        <NotFound>
            <PageTitle>Not found</PageTitle>
            <LayoutView Layout="@typeof(MainLayout)">
                <p role="alert">Sorry, there's nothing at this address.</p>
            </LayoutView>
        </NotFound>
    </Router>
</CascadingAuthenticationState>

在我的program.cs中有：builder.Services.AddScoped<CustomAuthenticationStateProvider, CustomAuthenticationStateProvider>(); builder.Services.AddScoped<AuthenticationStateProvider>(s => s.GetRequiredService<CustomAuthenticationStateProvider>());
和
app.UseAuthentication(); app.UseAuthorization();个
为了测试我的导航栏，我把这个：

<AuthorizeView>
        <Authorized>
            Auth
        </Authorized>
        <NotAuthorized>
            Not Auth
        </NotAuthorized>
    </AuthorizeView>

我试着在一个新的blazor服务器应用程序中实现同样的代码，它似乎像预期的那样工作。在那个应用程序中，我可以在GetAuthenticationStateAsync（）中的返回处设置一个断点，当应用程序启动时，它会中断，这不是我一直在工作的实际应用程序的情况。除非我调用登录退出logout函数，否则GetAuthenticationStateAsync（）永远不会被调用。
