如何在启动web应用程序时先打开索引而不是身份？ASP.NET核心MVC

public void ConfigureServices(IServiceCollection services)
{
    // 添加身份验证服务
    services.AddAuthentication(options =>
    {
        options.DefaultScheme = "Cookies";
        options.DefaultChallengeScheme = "oidc";
    })
    .AddCookie("Cookies")
    .AddOpenIdConnect("oidc", options =>
    {
        // 配置OpenID Connect身份验证参数
        options.Authority = "https://your-identity-provider.com";
        options.ClientId = "your-client-id";
        options.ClientSecret = "your-client-secret";
        options.ResponseType = "code";
        options.Scope.Add("openid");
        options.Scope.Add("profile");
        options.SaveTokens = true;
    });

    // 添加MVC服务
    services.AddMvc();
}

public void Configure(IApplicationBuilder app, IHostingEnvironment env)
{
    if (env.IsDevelopment())
    {
        app.UseDeveloperExceptionPage();
    }
    else
    {
        app.UseExceptionHandler("/Home/Error");
        app.UseHsts();
    }

    // 配置身份验证中间件
    app.UseAuthentication();

    // 配置路由
    app.UseMvc(routes =>
    {
        routes.MapRoute(
            name: "default",
            template: "{controller=Home}/{action=Index}/{id?}");
    });
}
