java - 如何在 spring-social-facebook 中处理 ExpiredAuthorizationException(授权已过期)

Question

我正在使用 spring-social-facebook 有时，在一段时间后身份验证似乎过期并且我收到此异常:

org.springframework.social.ExpiredAuthorizationException: The authorization has expired.
    at org.springframework.social.facebook.api.impl.FacebookErrorHandler.handleFacebookError(FacebookErrorHandler.java:83)
    at org.springframework.social.facebook.api.impl.FacebookErrorHandler.handleError(FacebookErrorHandler.java:59)
    at org.springframework.web.client.RestTemplate.handleResponse(RestTemplate.java:667)
    at org.springframework.web.client.RestTemplate.doExecute(RestTemplate.java:620)
    at org.springframework.web.client.RestTemplate.execute(RestTemplate.java:595)
    at org.springframework.web.client.RestTemplate.getForObject(RestTemplate.java:303)
    at org.springframework.social.facebook.api.impl.SocialContextTemplate.getSocialContext(SocialContextTemplate.java:120)

不知道怎么处理这个错误...能不能认证过期后自动重连？

使用的版本:

 <dependency>
    <groupId>org.springframework.social</groupId>
    <artifactId>spring-social-facebook</artifactId>
    <version>2.0.4.BUILD-SNAPSHOT</version>
</dependency>

<dependency>
    <groupId>org.springframework.social</groupId>
    <artifactId>spring-social-core</artifactId>
    <version>1.1.4.RELEASE</version>
</dependency>

我在 SO 中发现了类似的问题:

• How to handle ExpiredAuthorizationException happening in spring social facebook? 我认为此解决方案不适用于我的新版本。
• How to recover from a Spring Social ExpiredAuthorizationException :此解决方案仅适用于 spring-social-google 特定情况。

如有任何帮助，我们将不胜感激。

要解决此问题，您必须将 ReconnectFilter 添加到社交配置 Java 文件中:

    @Bean
    public ReconnectFilter apiExceptionHandler(UsersConnectionRepository usersConnectionRepository, UserIdSource userIdSource) {
        return new ReconnectFilter(usersConnectionRepository, userIdSource);
    }

此 ReconnectFilter 依赖于 UserIdSource Bean 来检索用户信息并刷新连接。你必须覆盖它:

 @Override
    @Bean
    public UserIdSource getUserIdSource() {
        return new UserIdSource() {
            @Override
            public String getUserId() {
                User user = getUser();
                if (user == null) {
                    throw new IllegalStateException("Unable to get a ConnectionRepository: no user signed in");
                }
                return user.getId();
            }
        };
    }

您可以在下面看到整个社交配置文件:

@Configuration
@PropertySource("classpath:application.properties")
@EnableSocial
public class SocialConfig  extends SocialConfigurerAdapter {

    @Override
    public void addConnectionFactories(ConnectionFactoryConfigurer cfConfig, Environment env) {
        cfConfig.addConnectionFactory(new FacebookConnectionFactory(env.getProperty("facebook.appKey"), env.getProperty("facebook.appSecret")));
    }


    @Bean
    public UsersConnectionRepository usersConnectionRepository(ConnectionFactoryLocator connectionFactoryLocator) {
        return new UserConnectionRepositoryImpl(connectionFactoryLocator);
    }

    @Override
    @Bean
    public UserIdSource getUserIdSource() {
        return new UserIdSource() {
            @Override
            public String getUserId() {
                User user = getUser();
                if (user == null) {
                    throw new IllegalStateException("Unable to get a ConnectionRepository: no user signed in");
                }
                return user.getId();
            }
        };
    }

    @Bean
    public ReconnectFilter apiExceptionHandler(UsersConnectionRepository usersConnectionRepository, UserIdSource userIdSource) {
        return new ReconnectFilter(usersConnectionRepository, userIdSource);
    }


    @Bean
    @Scope(value = "request", proxyMode = ScopedProxyMode.INTERFACES)
    public ConnectionRepository connectionRepository(ConnectionFactoryLocator connectionFactoryLocator) {

        User user = getUser();
        if (user == null) {
            throw new IllegalStateException("Unable to get a ConnectionRepository: no user signed in");
        }
        return usersConnectionRepository(connectionFactoryLocator).createConnectionRepository(user.getId());
    }

    @Bean
    @Scope(value = "request", proxyMode = ScopedProxyMode.INTERFACES)
    public Facebook facebook(ConnectionRepository repository) {
        Connection<Facebook> connection = null;

        if (repository != null) {
           connection = repository.findPrimaryConnection(Facebook.class);
        }

        return connection != null ? connection.getApi() : null;
    }
