.net core AWS Cognito.NET核心3.1集成

一般来说，我对.NET比较陌生，我正在尝试使用AWS Cognito为我的API创建一个简单的身份验证。我一直在网上阅读指南，但似乎没有一本适合我。这是我如何配置Startup.cs的：

public void ConfigureServices(IServiceCollection services)
{
    services.AddMemoryCache();
    services.AddControllersWithViews();
    services.AddAuthentication(options =>
        {
            options.DefaultAuthenticateScheme = CookieAuthenticationDefaults.AuthenticationScheme;
            options.DefaultSignInScheme = CookieAuthenticationDefaults.AuthenticationScheme;
            options.DefaultChallengeScheme = OpenIdConnectDefaults.AuthenticationScheme;
        })
        .AddCookie()
        .AddOpenIdConnect(options =>
        {
            options.ResponseType = Configuration["Authentication:Cognito:ResponseType"];
            options.MetadataAddress = Configuration["Authentication:Cognito:MetadataAddress"];
            options.ClientId = Configuration["Authentication:Cognito:ClientId"];
        });
}

// This method gets called by the runtime. Use this method to configure the HTTP request pipeline.
public void Configure(IApplicationBuilder app, IWebHostEnvironment env)
{
    app.UseRouting();
    app.UseAuthentication();
    app.UseAuthorization();

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

我已正确填写了我的配置。当我通过

[Authorize]

保护页面时，我被重定向到AWS Cognito登录，然后我被重定向到

https://localhost:5001/signin-oidc？code=…

其中我在控制台中得到一个空白页和一个错误，说明：

      Message contains error: 'invalid_client', error_description: 'error_description is null', error_uri: 'error_uri is null', status code '400'.

我已经尝试确保AWS端没有错误，并且我能够看到代码和状态被发送回应用程序。

设置用户池时，您是否使用客户端密码创建了它？当池需要客户机密时，我遇到了同样的问题。@tobyb对不起，我不记得了，很久以前的事了：(
