C# 什么'；OWIN中IIS主机的默认OAuth AccessTokenFormat实现是什么？

默认/令牌端点工作正常，我可以从那里获得令牌， 但是我需要使用票据上的AccessTokenFormat.Protect方法为externalLogin生成accessToken

基本上，我的实现与此基本相同，并且我遇到了AccessTokenFormat为null的相同问题。 它说：

用于保护访问令牌中包含的信息的数据格式。如果应用程序未提供，则默认数据保护提供程序取决于主机服务器。IIS上的SystemWeb主机将使用ASP.NET计算机密钥数据保护，HttpListener和其他自托管服务器将使用DPAPI数据保护。如果分配了不同的访问令牌提供程序或格式，则必须将兼容实例分配给资源服务器的OAuthBeareAuthenticationOptions.AccessTokenProvider或OAuthBeareAuthenticationOptions.AccessTokenFormat属性

在我看来，如果未分配AccessTokenFormat，主机将为其提供基本实现。但我觉得在这里不管用。 有没有办法找到ISecureDataFormatAccessTokenFormat的默认实现并手动将其分配给变量

或者有没有人对如何解决这个问题有其他想法

更新： 我获得了katana的源代码并找到了OAuthAuthorizationServerMiddleware类，从源代码中我可以看到以下代码：

if (Options.AccessTokenFormat == null)
        {
            IDataProtector dataProtecter = app.CreateDataProtector(
                typeof(OAuthAuthorizationServerMiddleware).Namespace,
                "Access_Token", "v1");
            Options.AccessTokenFormat = new TicketDataFormat(dataProtecter);
        }

在我的Startup.Auth中，以下是我的代码：

     static Startup()
    {
        PublicClientId = "self";

        UserManagerFactory = () => new UserManager<ApplicationUser>(new UserStore<ApplicationUser>(new ApplicationDbContext()));

        OAuthOptions = new OAuthAuthorizationServerOptions()
        {
            TokenEndpointPath = new PathString("/Token"),
            AuthorizeEndpointPath = new PathString("/api/Account/ExternalLogin"),
            Provider = new ApplicationOAuthProvider(PublicClientId, UserManagerFactory),
            AccessTokenExpireTimeSpan = TimeSpan.FromDays(14),
            AllowInsecureHttp = true
        };

        OAuthBearerOptions = new OAuthBearerAuthenticationOptions();
        OAuthBearerOptions.AccessTokenFormat = OAuthOptions.AccessTokenFormat;
        OAuthBearerOptions.AccessTokenProvider = OAuthOptions.AccessTokenProvider;
        OAuthBearerOptions.AuthenticationMode = OAuthOptions.AuthenticationMode;
        OAuthBearerOptions.AuthenticationType = OAuthOptions.AuthenticationType;
        OAuthBearerOptions.Description = OAuthOptions.Description;

        OAuthBearerOptions.Provider = new CustomBearerAuthenticationProvider();
        OAuthBearerOptions.SystemClock = OAuthOptions.SystemClock;
    }

    public void ConfigureAuth(IAppBuilder app)
    {
        // Configure the db context and user manager to use a single instance per request
        app.CreatePerOwinContext(ApplicationDbContext.Create);
        app.CreatePerOwinContext<ApplicationUserManager>(ApplicationUserManager.Create);


        app.UseOAuthAuthorizationServer(OAuthOptions);

        // Enable the application to use bearer tokens to authenticate users
        app.UseOAuthBearerTokens(OAuthOptions);
        // Enable the application to use a cookie to store information for the signed in user
        // and to use a cookie to temporarily store information about a user logging in with a third party login provider
        // Configure the sign in cookie
        app.UseCookieAuthentication(new CookieAuthenticationOptions
        {
            AuthenticationType = DefaultAuthenticationTypes.ApplicationCookie,
            LoginPath = new PathString("/Account/Login"),
            Provider = new CookieAuthenticationProvider
            {
                OnValidateIdentity = SecurityStampValidator.OnValidateIdentity<ApplicationUserManager, ApplicationUser>(
                    validateInterval: TimeSpan.FromMinutes(30),
                    regenerateIdentity: (manager, user) => user.GenerateUserIdentityAsync(manager))
            }
        });
        // Use a cookie to temporarily store information about a user logging in with a third party login provider
        app.UseExternalSignInCookie(DefaultAuthenticationTypes.ExternalCookie);

我不知道为什么

app.useAuthAuthorizationServer（OAuthOptions）

没有设置accessTokenFormat

我不确定它为什么没有正确设置，但我取出代码并自行分配给它。以下是我的最终工作代码：
