c# - OWIN for IIS主机中默认的OAuth AccessTokenFormat实现是什么？

Web API 2 OWIN Bearer token authentication - AccessTokenFormat null?

默认的/Token端点工作正常，我可以从那里获取 token ，
但是我需要在票证上使用AccessTokenFormat.Protect方法来为externalLogin生成accessToken。

基本上，我的实现与这一实现几乎相同，并且我遇到了AccessTokenFormat为null的相同问题。
从documentation中说:



在我看来，如果未分配AccessTokenFormat，则主机将为其提供基本的实现。但我看不到它在这里起作用。
有没有一种方法可以找到ISecureDataFormatAccessTokenFormat的默认实现并将其手动分配给变量？

还是有人对解决这个问题有其他想法？

更新:
我获得了katana的源代码，并从源代码中找到了OAuthAuthorizationServerMiddleware类，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，这是我的代码:

     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);

}

我在WebApiConfig中也有以下内容

// Web API configuration and services
        // Configure Web API to use only bearer token authentication.
        config.SuppressDefaultHostAuthentication();
        config.Filters.Add(new HostAuthenticationFilter(OAuthDefaults.AuthenticationType));

我不确定为什么app.UseOAuthAuthorizationServer(OAuthOptions);没有设置accessTokenFormat

最佳答案

我不确定为什么设置不正确，但是我拔出了代码并分配给我自己。这是我最终的工作代码如下:

      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);


        OAuthOptions = new OAuthAuthorizationServerOptions()
        {
            TokenEndpointPath = new PathString("/Token"),
            Provider = new ApplicationOAuthProvider(PublicClientId, UserManagerFactory),
            AccessTokenFormat = new TicketDataFormat(app.CreateDataProtector(
               typeof(OAuthAuthorizationServerMiddleware).Namespace,
               "Access_Token", "v1")),
            RefreshTokenFormat = new TicketDataFormat(app.CreateDataProtector(
                typeof(OAuthAuthorizationServerMiddleware).Namespace,
                "Refresh_Token", "v1")),
            AccessTokenProvider = new AuthenticationTokenProvider(),
            RefreshTokenProvider = new AuthenticationTokenProvider(),
            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;

        app.UseOAuthAuthorizationServer(OAuthOptions);
        app.UseOAuthBearerAuthentication(OAuthBearerOptions);

        // 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);
        }
