我正在尝试创建 RevalidatingServerAuthenticationStateProvider 来检查 ClaimsPrincipal 是否已过期。

我已经创建了它的实现（TokenExpiryAuthStateProvider）并将其注册到ConfigureServices 中，但构造函数从未被调用，ValidateAuthenticationStateAsync 也未被调用。（我也尝试了实现工厂来注册它，结果相同）

我将 AuthStateProvider 注入到 MainLayout 中以查看注入的内容，但它仍在注入 ServerAuthenticationStateProvider。我究竟做错了什么？

我的实现从未被调用：

public class TokenExpiryAuthStateProvider : RevalidatingServerAuthenticationStateProvider
{
    protected override TimeSpan RevalidationInterval => TimeSpan.FromSeconds(10);

    public TokenExpiryAuthStateProvider(ILoggerFactory logger) : base(logger)
    {

    }

    protected override Task<bool> ValidateAuthenticationStateAsync(AuthenticationState authenticationState, CancellationToken cancellationToken)
    {
        DateTime expiry = authenticationState.User.GetExpiryDate();

        if (expiry < DateTime.UtcNow)
            return Task.FromResult(false);
        else
            return Task.FromResult(true);
    }
}

配置服务

public void ConfigureServices(IServiceCollection services)
    {
        services.AddScoped<HttpClientFactory>();

        services.AddAuthentication(CookieAuthenticationDefaults.AuthenticationScheme).AddCookie();
        services.ConfigureApplicationCookie(options =>
        {
            options.Cookie.HttpOnly = true;
            options.SlidingExpiration = true;
            options.ExpireTimeSpan = TimeSpan.FromMinutes(5);
        });

        services.AddScoped<AuthenticationStateProvider, …
