我正在尝试实现ASP.NETCore6.0MVC应用程序的注销功能（WebAPI不是一个单独的项目）。
然而，当我尝试注销应用程序时，我得到404错误请求-错误：
post_logout_redirect_uri "参数必须是客户端应用程序设置中的注销重定向URI
下面是program.cs：

appBuilder.Services.AddAuthentication(options =>
{
    options.DefaultScheme = CookieAuthenticationDefaults.AuthenticationScheme;
    options.DefaultChallengeScheme = OpenIdConnectDefaults.AuthenticationScheme;
})    
   .AddCookie(CookieAuthenticationDefaults.AuthenticationScheme, options =>
     {
         options.ExpireTimeSpan = TimeSpan.FromMinutes(10);
         options.SlidingExpiration = true;
     })
   .AddOpenIdConnect(options =>
{
    options.SignInScheme = CookieAuthenticationDefaults.AuthenticationScheme;
    options.Authority = config.GetValue<string>("Okta:Domain");
    options.ClientId = config.GetValue<string>("Okta:ClientId");
    options.ClientSecret = config.GetValue<string>("Okta:ClientSecret");

    options.GetClaimsFromUserInfoEndpoint = true;
    options.ResponseType = OpenIdConnectResponseType.Code;
    options.UseTokenLifetime = true;
    options.Scope.Add("openid");
    options.Scope.Add("profile");
    options.Scope.Add("email");
    options.SaveTokens = true;
    options.UseTokenLifetime = true;
    options.RequireHttpsMetadata = true;
    options.CallbackPath = "/signin-oidc";
    options.SignedOutRedirectUri = "/Home/Logout";
 
    if (config.GetValue<string>("env") != "localhost")
    {
        var proxyUri = new WebProxy(new Uri(config["ProxyURL"]), BypassOnLocal: false);
        var proxyHttpClientHandler = new HttpClientHandler
        {
            Proxy = proxyUri,
            UseProxy = true,
            SslProtocols = System.Security.Authentication.SslProtocols.Tls | System.Security.Authentication.SslProtocols.Tls11 | System.Security.Authentication.SslProtocols.Tls12
        };
        var httpClient = new HttpClient(proxyHttpClientHandler)
        {            
            Timeout = TimeSpan.FromMinutes(10)
        };        
        options.BackchannelHttpHandler = new HttpClientHandler
        {
            ServerCertificateCustomValidationCallback = (message, cert, chain, errors) => true,
            Proxy = proxyHttpClientHandler.Proxy,        
        };        
    }

    options.Events = new OpenIdConnectEvents
    {
        OnRedirectToIdentityProvider = async ctx =>
        {          
            ctx.ProtocolMessage.RedirectUri = config.GetValue<string>("Okta:RedirectUri");
            await Task.FromResult(0);
        },

        OnRedirectToIdentityProviderForSignOut = async ctx =>
        {            
            ctx.ProtocolMessage.PostLogoutRedirectUri = config.GetValue<string>("Okta:PostLogoutRedirectUri");
            await Task.CompletedTask;
        },

        OnUserInformationReceived = async context =>
        {   
            string rAccessToken = context.ProtocolMessage.AccessToken;
            string rIdToken = context.ProtocolMessage.IdToken;
            var handler = new JwtSecurityTokenHandler();
            var accessToken = handler.ReadJwtToken(rAccessToken);
            var idToken = handler.ReadJwtToken(rIdToken);
        },

        OnTicketReceived = async context =>
        {
        },

        OnAuthenticationFailed = async context =>
        {
        },

        OnSignedOutCallbackRedirect = async context =>
        {          
        }
    };
});

appBuilder.Services.AddAuthorization();

appsettings.json：

"Okta": {
    "ClientId": "123Ac0n28iK9MH3Oc297",
    "ClientSecret": "325twLwoWrgBY6ep-Imgsrg43_12cIo6jA993j2VU",
    "Domain": "https://login-bb.zzz/oauth2/default",
    "PostLogoutRedirectUri": "https://localhost:22334/signout-callback-oidc",
    "RedirectUri": "https://localhost:22334/signin-oidc",
    "SignOutRedirectUri": "https://localhost:22334/signout-oidc"
  },

控制器：

[HttpPost]
public async Task Logout()
{
        if (User.Identity.IsAuthenticated)
        {
            await HttpContext.SignOutAsync(CookieAuthenticationDefaults.AuthenticationScheme);
            await HttpContext.SignOutAsync(OpenIdConnectDefaults.AuthenticationScheme);
        }
}

如果将PostLogoutRedirectUri设置为NULL，它将注销应用程序并重定向到登录页面，但是，在登录时，它不会将我带回应用程序，而是将我重定向到okta主页。
我很感激你的建议。
