Spring Social Authentication Filter for Stateless REST Endpoints 使用 Facebook Token 进行身份验证

Question

我想使用Facebook Tokens 使用Spring Security 对我的REST 后端进行身份验证。您能否详细说明如何将这种安全性集成到我的 Spring 应用程序中。

我想使用与 Spring Social Security 相同的用户管理。 UserConnection 表和本地用户表。

Answer 1

您可以从以下网址下载代码示例：

https://github.com/ozgengunay/FBSpringSocialRESTAuth

我们一直在寻找一种“Spring”解决方案，该解决方案使用 REST 客户端已经拥有的 Facebook OAuth 令牌来保护我们的 REST 后端。例如：您有一个在应用程序本身中实现了 Facebook Connect SDK 的移动应用程序，另一方面，您有一个提供 REST API 的后端。您想使用 Facebook OAuth 令牌对 REST API 调用进行身份验证。解决方案实现了这种场景。

不幸的是，Spring Social Security Framework 只保护有状态的 HTTP 请求，而不是无状态的 REST 后端。

这是 spring 社会保障框架的扩展，由一个组件组成：FacebookTokenAuthenticationFilter。此过滤器拦截所有 REST 调用。客户端应在每个请求中将 Facebook OAuth 令牌作为“input_token”参数在 url 中发送，因为 REST API 本质上是无声的。过滤器查找此令牌并通过“debug_token”Graph Api 调用对其进行验证。如果令牌通过验证，过滤器会尝试将用户与本地用户管理系统进行匹配。如果还没有这样的用户注册，过滤器会将该用户注册为新用户。

如果您还有 REST API 以外的服务（例如 Web 后端），则可以将此过滤器与 Spring Social Security 的标准 SocialAuthenticationFilter 一起使用。因此您可以使用相同的用户管理系统。

1) 在 MYSQL 中创建您的用户表，如下所示：

CREATE TABLE IF NOT EXISTS `user` (
  `id` varchar(50) NOT NULL,
  `email` varchar(255) NOT NULL COMMENT 'unique',
  `first_name` varchar(255) NOT NULL,
  `last_name` varchar(255) NOT NULL,
  `password` varchar(255) DEFAULT NULL,
  `role` varchar(255) NOT NULL,
  `sign_in_provider` varchar(20) DEFAULT NULL,
  `creation_time` datetime NOT NULL,
  `modification_time` datetime NOT NULL,
  `status` varchar(20) NOT NULL COMMENT 'not used',
  PRIMARY KEY (`id`),
  UNIQUE KEY `email` (`email`)
);

2) 在 context.xml 中配置你的数据源：

tomcat 中的context.xml：

<Resource auth="Container" driverClassName="com.mysql.jdbc.Driver" maxActive="100" maxIdle="30" maxWait="10000" 
name="jdbc/thingabled" password="..." type="javax.sql.DataSource" url="jdbc:mysql://localhost:3306/..." username="..."/>

3) Spring 配置：我们配置 Spring Security 以拦截以“protected”开头的 URL，由 FacebookTokenAuthenticationFilter 进行身份验证。授权将由“ROLE_USER_REST_MOBILE”角色完成。

<security:http use-expressions="true" pattern="/protected/**"
create-session="never" entry-point-ref="forbiddenEntryPoint">
  <security:intercept-url pattern="/**"
  access="hasRole('ROLE_USER_REST_MOBILE')" />
<!-- Adds social authentication filter to the Spring Security filter chain. -->
  <security:custom-filter ref="facebookTokenAuthenticationFilter"
  before="FORM_LOGIN_FILTER" />
</security:http>


<bean id="facebookTokenAuthenticationFilter"
class="com.ozgen.server.security.oauth.FacebookTokenAuthenticationFilter">
  <constructor-arg index="0" ref="authenticationManager" />
  <constructor-arg index="1" ref="userIdSource" />
  <constructor-arg index="2" ref="usersConnectionRepository" />
  <constructor-arg index="3" ref="connectionFactoryLocator" />
</bean>

<security:authentication-manager alias="authenticationManager">
  <security:authentication-provider
  ref="socialAuthenticationProvider" />
</security:authentication-manager>

<!-- Configures the social authentication provider which processes authentication 
requests made by using social authentication service (FB). -->
<bean id="socialAuthenticationProvider"
class="org.springframework.social.security.SocialAuthenticationProvider">
  <constructor-arg index="0" ref="usersConnectionRepository" />
  <constructor-arg index="1" ref="simpleSocialUserDetailsService" />
</bean>

<bean id="forbiddenEntryPoint"
class="org.springframework.security.web.authentication.Http403ForbiddenEntryPoint" />

<!-- This bean determines the account ID of the user.-->
<bean id="userIdSource"
class="org.springframework.social.security.AuthenticationNameUserIdSource" />

<!-- This is used to hash the password of the user. -->
<bean id="passwordEncoder"
class="org.springframework.security.crypto.bcrypt.BCryptPasswordEncoder">
  <constructor-arg index="0" value="10" />
</bean>
<!-- This bean encrypts the authorization details of the connection. In 
our example, the authorization details are stored as plain text. DO NOT USE 
THIS IN PRODUCTION. -->
<bean id="textEncryptor" class="org.springframework.security.crypto.encrypt.Encryptors"
factory-method="noOpText" />

4) 所有无状态的 REST 请求都将被 FacebookTokenAuthenticationFilter 拦截，以使用有效的 Facebook Token 对请求进行身份验证。检查 Facebook 令牌是否有效。如果 Facebook 令牌无效，则请求将被拒绝。如果 Facebook 令牌有效，则过滤器将尝试通过 SimpleSocialUserDetailsS​​ervice 验证请求。如果用户和用户连接数据不可用，则会创建一个新用户（通过 UserService）和 UserConnection。

private Authentication attemptAuthService(...) {
  if (request.getParameter("input_token") == null) {
    throw new SocialAuthenticationException("No token in the request");
  }
  URIBuilder builder = URIBuilder.fromUri(String.format("%s/debug_token", "https://graph.facebook.com"));
  builder.queryParam("access_token", access_token);
  builder.queryParam("input_token", request.getParameter("input_token"));
  URI uri = builder.build();
  RestTemplate restTemplate = new RestTemplate();

  JsonNode resp = null;
  try {
    resp = restTemplate.getForObject(uri, JsonNode.class);
  } catch (HttpClientErrorException e) {
    throw new SocialAuthenticationException("Error validating token");
  }
  Boolean isValid = resp.path("data").findValue("is_valid").asBoolean();
  if (!isValid)
    throw new SocialAuthenticationException("Token is not valid");

  AccessGrant accessGrant = new AccessGrant(request.getParameter("input_token"), null, null,
    resp.path("data").findValue("expires_at").longValue());

  Connection<?> connection = ((OAuth2ConnectionFactory<?>) authService.getConnectionFactory())
    .createConnection(accessGrant);
  SocialAuthenticationToken token = new SocialAuthenticationToken(connection, null);
  Assert.notNull(token.getConnection());

  Authentication auth = SecurityContextHolder.getContext().getAuthentication();
  if (auth == null || !auth.isAuthenticated()) {
    return doAuthentication(authService, request, token);
  } else {
    addConnection(authService, request, token);
    return null;
  }
 }

5) 项目中的其他重要部分：

用户：映射“用户”表的实体。

@Entity
@Table(name = "user")
public class User extends BaseEntity {

  @Column(name = "email", length = 255, nullable = false, unique = true)
  private String email;

  @Column(name = "first_name", length = 255, nullable = false)
  private String firstName;

  @Column(name = "last_name", length = 255, nullable = false)
  private String lastName;

  @Column(name = "password", length = 255)
  private String password;

  @Column(name = "role", length = 255, nullable = false)
  private String rolesString;

  @Enumerated(EnumType.STRING)
  @Column(name = "sign_in_provider", length = 20)
  private SocialMediaService signInProvider;

  ...
}

UserRepository : Spring Data JPA 存储库，它将使我们能够在“用户”实体上运行 CRUD 操作。

public interface UserRepository extends JpaRepository<User, String> {
  public User findByEmailAndStatus(String email,Status status);
  public User findByIdAndStatus(String id,Status status);
}

UserService : 这个 spring 服务将用于创建一个新的用户帐户，将数据插入到 'user' 表中。

@Service
public class UserService {
  private static final Logger LOGGER = LoggerFactory.getLogger(UserService.class);

  @Autowired
  private UserRepository repository;

  @Transactional
  public User registerNewUserAccount(RegistrationForm userAccountData) throws DuplicateEmailException {
      LOGGER.debug("Registering new user account with information: {}", userAccountData);

      if (emailExist(userAccountData.getEmail())) {
          LOGGER.debug("Email: {} exists. Throwing exception.", userAccountData.getEmail());
          throw new DuplicateEmailException("The email address: " + userAccountData.getEmail() + " is already in use.");
      }

      LOGGER.debug("Email: {} does not exist. Continuing registration.", userAccountData.getEmail());

      User registered =User.newEntity();
      registered.setEmail(userAccountData.getEmail());
      registered.setFirstName(userAccountData.getFirstName());
      registered.setLastName(userAccountData.getLastName());
      registered.setPassword(null);
      registered.addRole(User.Role.ROLE_USER_WEB);
      registered.addRole(User.Role.ROLE_USER_REST);
      registered.addRole(User.Role.ROLE_USER_REST_MOBILE);

      if (userAccountData.isSocialSignIn()) {
          registered.setSignInProvider(userAccountData.getSignInProvider());
      }

      LOGGER.debug("Persisting new user with information: {}", registered);

      return repository.save(registered);
  }
  .... 
}

SimpleSocialUserDetailsS​​ervice : 这个 Spring 服务将被 SocialAuthenticationProvider 用来验证用户的 userId。

@Service
public class SimpleSocialUserDetailsService implements SocialUserDetailsService {
  private static final Logger LOGGER = LoggerFactory.getLogger(SimpleSocialUserDetailsService.class);
  @Autowired
  private UserRepository repository;

  @Override
  public SocialUserDetails loadUserByUserId(String userId) throws UsernameNotFoundException, DataAccessException {
      LOGGER.debug("Loading user by user id: {}", userId);

      User user = repository.findByEmailAndStatus(userId, Status.ENABLED);
      LOGGER.debug("Found user: {}", user);

      if (user == null) {
          throw new UsernameNotFoundException("No user found with username: " + userId);
      }

      ThingabledUserDetails principal = new ThingabledUserDetails(user.getEmail(),user.getPassword(),user.getAuthorities());
      principal.setFirstName(user.getFirstName());
      principal.setId(user.getId());
      principal.setLastName(user.getLastName());
      principal.setSocialSignInProvider(user.getSignInProvider());


      LOGGER.debug("Found user details: {}", principal);

      return principal;
  }
}
