在 IIS 上发布我的 ASP.NET Web 表单应用程序时，OnRedirectToIdentityProvider 不会触发

Question

我有一个 ASP.NET Web 表单和一个 Web API，位于 IIS Express 本地，当用户导航到特定网页时，会自动调用我的自定义身份服务器，从而触发

OnRedirectToIdentityProvider

事件。

如果我将此应用程序发布到 IIS，则不会发生任何事情（当用户单击登录链接页面时，代码返回 http 200 而不是触发上述事件）。

这是我的代码：

app.SetDefaultSignInAsAuthenticationType(CookieAuthenticationDefaults.AuthenticationType);

app.UseCookieAuthentication(new CookieAuthenticationOptions
{
    AuthenticationType = DefaultAuthenticationTypes.ApplicationCookie,
    AuthenticationMode =  Microsoft.Owin.Security.AuthenticationMode.Passive
});

app.UseOpenIdConnectAuthentication(new OpenIdConnectAuthenticationOptions
{
    AuthenticationType = OpenIdConnectAuthenticationDefaults.AuthenticationType, //"oidc";
    ClientId = WebConfigurationManager.AppSettings["ClientId"],
    BackchannelTimeout = System.TimeSpan.FromMinutes(30),
    CallbackPath = new PathString("/Account/Login"),        
    Authority = WebConfigurationManager.AppSettings["Authority"],
    PostLogoutRedirectUri = WebConfigurationManager.AppSettings["PostLogoutRedirectUri"],
    RedirectUri = WebConfigurationManager.AppSettings["RedirectUri"],
    Scope = "openid profile",
    ResponseType = "id_token",
    SaveTokens = true,
    Notifications = new OpenIdConnectAuthenticationNotifications
    {
        AuthenticationFailed = OnAuthenticationFailed,
        SecurityTokenValidated = OnSecurityTokenValidated,
        RedirectToIdentityProvider = OnRedirectToIdentityProvider,
        MessageReceived = OnMessageReceived,
        AuthorizationCodeReceived = OnAuthorizationCodeReceived,
        TokenResponseReceived = OnTokenResponseReceived,
        SecurityTokenReceived = OnSecurityTokenReceived,
    }
});

app.UseStageMarker(PipelineStage.Authenticate);

我自己找到了解决方案。 我的所有代码和相关库都没有任何问题。 有效的解决方案是删除位于与目标链接 aspx 文件相同的目录中的错误嵌套 Web 配置文件，从而禁用中间件重定向。
