我在 Spring MVC 项目中使用 Spring Social Facebook 来支持 Facebook 登录。这在几乎所有情况下都运行良好，但偶尔我会在日志中看到以下异常。

我无法弄清楚何时会发生这种情况，也无法重现它，但我已经多次看到其他用户发生这种情况。下面是我的 Spring Social Facebook 配置。

@Configuration
public class SocialConfig {
    @Bean
    public ProviderSignInController providerSignInController() {
        ProviderSignInController controller = new ProviderSignInController(this.connectionFactoryLocator(), this.usersConnectionRepository(), new SpringSecuritySignInAdapter(this.accountRepository));
        controller.addSignInInterceptor(new RedirectToPreviousPageInterceptor(controller, this.analyticsService));

        return controller;
    }

    @Bean
    public ConnectionFactoryRegistry connectionFactoryLocator() {
        ConnectionFactoryRegistry connectionFactoryRegistry = new ConnectionFactoryRegistry();
        List<ConnectionFactory<?>> connectionFactories = new ArrayList<ConnectionFactory<?>>();
        connectionFactories.add(this.facebookConnectionFactory());
        connectionFactoryRegistry.setConnectionFactories(connectionFactories);

        return connectionFactoryRegistry;
    }

    @Bean
    public FacebookConnectionFactory facebookConnectionFactory() {
        FacebookConnectionFactory connectionFactory = new FacebookConnectionFactory(this.facebookAppId, this.facebookAppSecret);
        connectionFactory.setScope(this.scope);

        return connectionFactory;
    }

    @Bean
    @Scope(value = "request", proxyMode = ScopedProxyMode.INTERFACES)
    public Facebook facebook(ConnectionRepository repository) {
        Connection<Facebook> connection = repository.findPrimaryConnection(Facebook.class);
        return (connection != null ? connection.getApi() : null);
    }

    @Bean
    @Scope(value = "request", proxyMode = ScopedProxyMode.INTERFACES)
    public ConnectionRepository connectionRepository() {
        Authentication authentication = SecurityContextHolder.getContext().getAuthentication();

        if (authentication == null) {
            throw new IllegalStateException("Unable to get a ConnectionRepository: no user signed in");
        }

        Account account = (Account) authentication.getPrincipal();
        return this.usersConnectionRepository().createConnectionRepository(String.valueOf(account.getId()));
    }

    @Bean
    public JdbcUsersConnectionRepository usersConnectionRepository() {
        JdbcUsersConnectionRepository repository = new JdbcUsersConnectionRepository(this.dataSource, this.connectionFactoryLocator(), this.textEncryptor);
        repository.setConnectionSignUp(this.accountService);

        return repository;
    }
}

为什么会发生这种情况，我能做些什么来防止这种情况发生？谢谢。

该state参数防止 OAuth2 中的 CSRF 攻击。

这个想法是：

  • 您的应用程序将state参数添加到它向身份验证服务器（在本例中为 Facebook）发出的请求中
  • 身份验证服务器在响应中将该state参数的确切值回显给您
  • 然后检查它们是否匹配

这听起来毫无意义......但它可以防止攻击者发出它没有启动的客户端应用程序操作请求。

这非常详细地介绍了它：

http://www.twobotechnologies.com/blog/2014/02/importance-of-state-in-oauth2.html

Spring Social 为您处理所有这些：state为每个请求生成一个新的随机数，并自动尝试将其与响应中的值匹配。

所以你不能阻止它：，你不想：这些可能是真正失败的攻击尝试——在这些情况下，你希望这个错误发生。

对于您发布的案例，它可能只是stateSpring Social 或 Facebook 的身份验证服务器对参数的错误处理。

但是，就您而言，您应该像处理真正的攻击尝试一样处理异常：记录警告/提醒人们/等等。

这个函数只是生成一个状态值字符串（默认情况下UUID.randomUUID().toString()），将它放在会话中，并将它作为授权请求中的“状态”参数传递给提供者。提供者应将其传递回回调。如果存储的状态与回调中的状态匹配，那么我们很好。如果它们不匹配，那就是当你看到你在那里提到的异常时。

这应该可以工作，但是是的，我看到您在这里遇到了问题。我还发现这个链接可能值得一看：https ://github.com/spring-projects/spring-social-facebook/issues/103
