ASP.NET Core 6 IdentityServer（DUENDE）：未找到defaultauthenticatescheme或在IdentityServeroptions上配置的cookieAthenticationscheme

Question

所以这是我们的设置。我们拥有

• Angular Web应用程序
• Identity Server API（ASP.NET Core 6，Duende Identity Server）

Indentity Server在 program.cs.cs 中：

    builder.Services
        .AddIdentity<ApplicationUser, IdentityRole>()
        .AddEntityFrameworkStores<ApplicationDbContext>()
        .AddDefaultTokenProviders();

    builder.Services
        .AddIdentityServer(options =>
        {
            options.Events.RaiseErrorEvents = true;
            options.Events.RaiseInformationEvents = true;
            options.Events.RaiseFailureEvents = true;
            options.Events.RaiseSuccessEvents = true;

            // see https://docs.duendesoftware.com/identityserver/v6/fundamentals/resources/
            options.EmitStaticAudienceClaim = true;
            options.IssuerUri = configuration["IssuerUri"];
        })
        .AddConfigurationStore(options =>
        {
            options.ConfigureDbContext = b =>
                b.UseMySql(conString, serverVersion, sqlOptions => sqlOptions.MigrationsAssembly(migrationsAssembly));
        })
        .AddOperationalStore(options =>
        {
            options.ConfigureDbContext = b =>
            {
                b.UseMySql(conString, serverVersion, sqlOptions => sqlOptions.MigrationsAssembly(migrationsAssembly));
            };
        })
        .AddAspNetIdentity<ApplicationUser>();
    
    builder.Services.AddAuthentication(options => {
            options.DefaultScheme = CookieAuthenticationDefaults.AuthenticationScheme;
            options.DefaultAuthenticateScheme = CookieAuthenticationDefaults.AuthenticationScheme;
            options.DefaultForbidScheme = CookieAuthenticationDefaults.AuthenticationScheme;
            options.DefaultSignInScheme = CookieAuthenticationDefaults.AuthenticationScheme;
            options.DefaultSignOutScheme = CookieAuthenticationDefaults.AuthenticationScheme;
            options.DefaultChallengeScheme = OpenIdConnectDefaults.AuthenticationScheme;
        })
return builder.Build();

然后，我们

app.useAuthorization();
    app.useAuthentication();

在Web应用程序试图获取OpenID时 呼叫从身份服务器URL（/.well-newand/openid-configuration）配置的配置，我们遇到此错误：

system.invalidoperationException：未找到defaultauthenticatescheme或在IdentityServeroptions上配置的cookiuthenticationsCheme。

Answer 1

我检查了您的代码并发现了两个错误：

1，如果您使用的是Cookie Authentication，并设置为以下内容：

您需要修改您的代码如下：

    builder.Services.AddAuthentication(options => 
     {
        ......
     })
   .AddCookie( "Cookies",options =>
    {
        ......;
    })

2，您需要移动代码：

app.useAuthentication();

在您面前

app.useAuthorization(); 

可以修改代码并重试，如果您可以共享有关更多代码，我可以测试为您

更新：
尝试设置您的IdentityServer auth选项：

builder.Services
        .AddIdentityServer(options =>
        {
            ......
            options.Authentication.CookieAuthenticationScheme= ....
            options.Authentication.CookieLifetime = .....
            .....
        });
