配置 OIDC 客户端：打开 Startup.cs 文件并添加以下代码：

services.AddAuthentication(options => { options.DefaultScheme = CookieAuthenticationDefaults.AuthenticationScheme; options.DefaultChallengeScheme = OpenIdConnectDefaults.AuthenticationScheme; }).AddCookie(options => { options.Cookie.SameSite = SameSiteMode.None; }).AddOpenIdConnect(options => { options.Authority = "https://localhost:5001"; options.ClientId = "blazor_oidc"; options.ClientSecret = "blazor_oidc_secret"; options.ResponseType = "code"; options.Scope.Add("openid"); options.Scope.Add("profile"); options.SaveTokens = true; });

在 Index.razor 页面中添加以下代码：

@page "/" @using Microsoft.AspNetCore.Components.WebAssembly.Authentication @inject SignOutSessionStateManager SignOutManager @implements IDisposable

Hello, @context.User.Identity.Name!

@code { private IDisposable stateChanged;

protected override void OnInitialized()
{
    stateChanged = SignOutManager.SubscribeToSignOutState((state) =>
    {
        if (state) // logout completion
        {
            // refresh the page to ensure a completely new circuit
            NavigationManager.NavigateTo("/authentication/logout");
        }
    });

    base.OnInitialized();
}

public void Dispose()
{
    stateChanged.Dispose();
}

private async Task StartAuthentication()
{
    var returnUrl = NavigationManager.ToAbsoluteUri(NavigationManager.Uri).ToString();

    var options = new AuthenticationOptions
    {
        AuthenticationPaths = new AuthenticationPaths
        {
            Login = "/authentication/login",
            Logout = "/authentication/logout",
            LogInFailed = "/authentication/login-failed"
        },
        ProviderOptions = new List
        {
            new OpenIdConnectOptions
            {
                SignInScheme = "Cookies",
                Authority
