在需要身份验证数据时，可以避免调用 "BuildServiceProvider" 方法，而使用 ASP.NET Core 中提供的内置身份验证中间件来处理身份验证。以下是一个示例代码：

using Microsoft.AspNetCore.Authentication;
using Microsoft.AspNetCore.Authentication.Cookies;
using Microsoft.AspNetCore.Authentication.OpenIdConnect;
using Microsoft.AspNetCore.Builder;
using Microsoft.AspNetCore.Hosting;
using Microsoft.AspNetCore.Http;
using Microsoft.Extensions.Configuration;
using Microsoft.Extensions.DependencyInjection;
using Microsoft.Extensions.Hosting;

public class Startup
{
    private IConfiguration Configuration { get; }

    public Startup(IConfiguration configuration)
    {
        Configuration = configuration;
    }

    public void ConfigureServices(IServiceCollection services)
    {
        services.AddAuthentication(options =>
        {
            options.DefaultScheme = CookieAuthenticationDefaults.AuthenticationScheme;
            options.DefaultChallengeScheme = OpenIdConnectDefaults.AuthenticationScheme;
        })
        .AddCookie(options =>
        {
            options.LoginPath = "/Account/Login";
            options.LogoutPath = "/Account/Logout";
        })
        .AddOpenIdConnect(options =>
        {
            options.Authority = Configuration["Authentication:OpenIdConnect:Authority"];
            options.ClientId = Configuration["Authentication:OpenIdConnect:ClientId"];
            options.ClientSecret = Configuration["Authentication:OpenIdConnect:ClientSecret"];
            options.CallbackPath = Configuration["Authentication:OpenIdConnect:CallbackPath"];
            options.ResponseType = Configuration["Authentication:OpenIdConnect:ResponseType"];
        });

        services.AddControllersWithViews();
    }

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

        app.UseHttpsRedirection();
        app.UseStaticFiles();

        app.UseRouting();

        app.UseAuthentication();
        app.UseAuthorization();

        app.UseEndpoints(endpoints =>
        {
            endpoints.MapControllerRoute(
                name: "default",
                pattern: "{controller=Home}/{action=Index}/{id?}");
        });
    }
}

在上述代码中，首先在 ConfigureServices 方法中将身份验证中间件添加到服务集合中。然后，在 Configure 方法中使用 app.UseAuthentication() 和 app.UseAuthorization() 将身份验证中间件添加到请求处理管道中。

需要注意的是，示例中的配置数据（如 Authority、ClientId、ClientSecret 等）应根据实际情况进行替换或读取。你可以在 appsettings.json 文件中设置这些配置项，并在 Startup 构造函数中通过 Configuration 属性读取它们。
