這篇文章主要介紹了Spring Security OAuth2集成短信驗證碼登錄以及第三方登錄，小編覺得挺不錯的，現(xiàn)在分享給大家，也給大家做個參考。一起跟隨小編過來看看吧

前言

基于SpringCloud做微服務(wù)架構(gòu)分布式系統(tǒng)時，OAuth2.0作為認(rèn)證的業(yè)內(nèi)標(biāo)準(zhǔn)，Spring Security OAuth2也提供了全套的解決方案來支持在Spring Cloud/Spring Boot環(huán)境下使用OAuth2.0，提供了開箱即用的組件。但是在開發(fā)過程中我們會發(fā)現(xiàn)由于Spring Security OAuth2的組件特別全面，這樣就導(dǎo)致了擴展很不方便或者說是不太容易直指定擴展的方案，例如：

圖片驗證碼登錄
短信驗證碼登錄
微信小程序登錄
第三方系統(tǒng)登錄
CAS單點登錄

在面對這些場景的時候，預(yù)計很多對Spring Security OAuth2不熟悉的人恐怕會無從下手。基于上述的場景要求，如何優(yōu)雅的集成短信驗證碼登錄及第三方登錄，怎么樣才算是優(yōu)雅集成呢？有以下要求：

不侵入Spring Security OAuth2的原有代碼
對于不同的登錄方式不擴展新的端點，使用/oauth/token可以適配所有的登錄方式
可以對所有登錄方式進行兼容，抽象一套模型只要簡單的開發(fā)就可以集成登錄

基于上述的設(shè)計要求，接下來將會在文章種詳細介紹如何開發(fā)一套集成登錄認(rèn)證組件開滿足上述要求。

閱讀本篇文章您需要了解OAuth2.0認(rèn)證體系、SpringBoot、SpringSecurity以及Spring Cloud等相關(guān)知識

思路

我們來看下Spring Security OAuth2的認(rèn)證流程：

這個流程當(dāng)中，切入點不多，集成登錄的思路如下：

在進入流程之前先進行攔截，設(shè)置集成認(rèn)證的類型，例如：短信驗證碼、圖片驗證碼等信息。
在攔截的通知進行預(yù)處理，預(yù)處理的場景有很多，比如驗證短信驗證碼是否匹配、圖片驗證碼是否匹配、是否是登錄IP白名單等處理
在UserDetailService.loadUserByUsername方法中，根據(jù)之前設(shè)置的集成認(rèn)證類型去獲取用戶信息，例如：通過手機號碼獲取用戶、通過微信小程序OPENID獲取用戶等等

接入這個流程之后，基本上就可以優(yōu)雅集成第三方登錄。

實現(xiàn)

介紹完思路之后，下面通過代碼來展示如何實現(xiàn)：

第一步，定義攔截器攔截登錄的請求

/**

 **/
@Component
public class IntegrationAuthenticationFilter extends GenericFilterBean implements ApplicationContextAware {

  private static final String AUTH_TYPE_PARM_NAME = "auth_type";

  private static final String OAUTH_TOKEN_URL = "/oauth/token";

  private Collection<IntegrationAuthenticator> authenticators;

  private ApplicationContext applicationContext;

  private RequestMatcher requestMatcher;

  public IntegrationAuthenticationFilter(){
    this.requestMatcher = new OrRequestMatcher(
        new AntPathRequestMatcher(OAUTH_TOKEN_URL, "GET"),
        new AntPathRequestMatcher(OAUTH_TOKEN_URL, "POST")
    );
  }

  @Override
  public void doFilter(ServletRequest servletRequest, ServletResponse servletResponse, FilterChain filterChain) throws IOException, ServletException {

    HttpServletRequest request = (HttpServletRequest) servletRequest;
    HttpServletResponse response = (HttpServletResponse) servletResponse;

    if(requestMatcher.matches(request)){
      //設(shè)置集成登錄信息
      IntegrationAuthentication integrationAuthentication = new IntegrationAuthentication();
      integrationAuthentication.setAuthType(request.getParameter(AUTH_TYPE_PARM_NAME));
      integrationAuthentication.setAuthParameters(request.getParameterMap());
      IntegrationAuthenticationContext.set(integrationAuthentication);
      try{
        //預(yù)處理
        this.prepare(integrationAuthentication);

        filterChain.doFilter(request,response);

        //后置處理
        this.complete(integrationAuthentication);
      }finally {
        IntegrationAuthenticationContext.clear();
      }
    }else{
      filterChain.doFilter(request,response);
    }
  }

  /**
   * 進行預(yù)處理
   * @param integrationAuthentication
   */
  private void prepare(IntegrationAuthentication integrationAuthentication) {

    //延遲加載認(rèn)證器
    if(this.authenticators == null){
      synchronized (this){
        Map<String,IntegrationAuthenticator> integrationAuthenticatorMap = applicationContext.getBeansOfType(IntegrationAuthenticator.class);
        if(integrationAuthenticatorMap != null){
          this.authenticators = integrationAuthenticatorMap.values();
        }
      }
    }

    if(this.authenticators == null){
      this.authenticators = new ArrayList<>();
    }

    for (IntegrationAuthenticator authenticator: authenticators) {
      if(authenticator.support(integrationAuthentication)){
        authenticator.prepare(integrationAuthentication);
      }
    }
  }

  /**
   * 后置處理
   * @param integrationAuthentication
   */
  private void complete(IntegrationAuthentication integrationAuthentication){
    for (IntegrationAuthenticator authenticator: authenticators) {
      if(authenticator.support(integrationAuthentication)){
        authenticator.complete(integrationAuthentication);
      }
    }
  }

  @Override
  public void setApplicationContext(ApplicationContext applicationContext) throws BeansException {
    this.applicationContext = applicationContext;
  }
}

在這個類種主要完成2部分工作：1、根據(jù)參數(shù)獲取當(dāng)前的是認(rèn)證類型，2、根據(jù)不同的認(rèn)證類型調(diào)用不同的IntegrationAuthenticator.prepar進行預(yù)處理

第二步，將攔截器放入到攔截鏈條中

/**
 * @author LIQIU
 * @date 2018-3-7
 **/
@Configuration
@EnableAuthorizationServer
public class AuthorizationServerConfiguration extends AuthorizationServerConfigurerAdapter {

  @Autowired
  private RedisConnectionFactory redisConnectionFactory;

  @Autowired
  private AuthenticationManager authenticationManager;

  @Autowired
  private IntegrationUserDetailsService integrationUserDetailsService;

  @Autowired
  private WebResponseExceptionTranslator webResponseExceptionTranslator;

  @Autowired
  private IntegrationAuthenticationFilter integrationAuthenticationFilter;

  @Autowired
  private DatabaseCachableClientDetailsService redisClientDetailsService;

  @Override
  public void configure(ClientDetailsServiceConfigurer clients) throws Exception {
    // TODO persist clients details
    clients.withClientDetails(redisClientDetailsService);
  }

  @Override
  public void configure(AuthorizationServerEndpointsConfigurer endpoints) {
    endpoints
        .tokenStore(new RedisTokenStore(redisConnectionFactory))
//        .accessTokenConverter(jwtAccessTokenConverter())
        .authenticationManager(authenticationManager)
        .exceptionTranslator(webResponseExceptionTranslator)
        .reuseRefreshTokens(false)
        .userDetailsService(integrationUserDetailsService);
  }

  @Override
  public void configure(AuthorizationServerSecurityConfigurer security) throws Exception {
    security.allowFormAuthenticationForClients()
        .tokenKeyAccess("isAuthenticated()")
        .checkTokenAccess("permitAll()")
        .addTokenEndpointAuthenticationFilter(integrationAuthenticationFilter);
  }

  @Bean
  public PasswordEncoder passwordEncoder() {
    return new BCryptPasswordEncoder();
  }

  @Bean
  public JwtAccessTokenConverter jwtAccessTokenConverter() {
    JwtAccessTokenConverter jwtAccessTokenConverter = new JwtAccessTokenConverter();
    jwtAccessTokenConverter.setSigningKey("cola-cloud");
    return jwtAccessTokenConverter;
  }
}

通過調(diào)用security. .addTokenEndpointAuthenticationFilter(integrationAuthenticationFilter);方法，將攔截器放入到認(rèn)證鏈條中。

第三步，根據(jù)認(rèn)證類型來處理用戶信息

@Service
public class IntegrationUserDetailsService implements UserDetailsService {

  @Autowired
  private UpmClient upmClient;

  private List<IntegrationAuthenticator> authenticators;

  @Autowired(required = false)
  public void setIntegrationAuthenticators(List<IntegrationAuthenticator> authenticators) {
    this.authenticators = authenticators;
  }

  @Override
  public User loadUserByUsername(String username) throws UsernameNotFoundException {
    IntegrationAuthentication integrationAuthentication = IntegrationAuthenticationContext.get();
    //判斷是否是集成登錄
    if (integrationAuthentication == null) {
      integrationAuthentication = new IntegrationAuthentication();
    }
    integrationAuthentication.setUsername(username);
    UserVO userVO = this.authenticate(integrationAuthentication);

    if(userVO == null){
      throw new UsernameNotFoundException("用戶名或密碼錯誤");
    }

    User user = new User();
    BeanUtils.copyProperties(userVO, user);
    this.setAuthorize(user);
    return user;

  }

  /**
   * 設(shè)置授權(quán)信息
   *
   * @param user
   */
  public void setAuthorize(User user) {
    Authorize authorize = this.upmClient.getAuthorize(user.getId());
    user.setRoles(authorize.getRoles());
    user.setResources(authorize.getResources());
  }

  private UserVO authenticate(IntegrationAuthentication integrationAuthentication) {
    if (this.authenticators != null) {
      for (IntegrationAuthenticator authenticator : authenticators) {
        if (authenticator.support(integrationAuthentication)) {
          return authenticator.authenticate(integrationAuthentication);
        }
      }
    }
    return null;
  }
}

這里實現(xiàn)了一個IntegrationUserDetailsService ，在loadUserByUsername方法中會調(diào)用authenticate方法，在authenticate方法中會當(dāng)前上下文種的認(rèn)證類型調(diào)用不同的IntegrationAuthenticator 來獲取用戶信息，接下來來看下默認(rèn)的用戶名密碼是如何處理的：

@Component
@Primary
public class UsernamePasswordAuthenticator extends AbstractPreparableIntegrationAuthenticator {

  @Autowired
  private UcClient ucClient;

  @Override
  public UserVO authenticate(IntegrationAuthentication integrationAuthentication) {
    return ucClient.findUserByUsername(integrationAuthentication.getUsername());
  }

  @Override
  public void prepare(IntegrationAuthentication integrationAuthentication) {

  }

  @Override
  public boolean support(IntegrationAuthentication integrationAuthentication) {
    return StringUtils.isEmpty(integrationAuthentication.getAuthType());
  }
}

UsernamePasswordAuthenticator只會處理沒有指定的認(rèn)證類型即是默認(rèn)的認(rèn)證類型，這個類中主要是通過用戶名獲取密碼。接下來來看下圖片驗證碼登錄如何處理的：

/**
 * 集成驗證碼認(rèn)證
 * @author LIQIU
 * @date 2018-3-31
 **/
@Component
public class VerificationCodeIntegrationAuthenticator extends UsernamePasswordAuthenticator {

  private final static String VERIFICATION_CODE_AUTH_TYPE = "vc";

  @Autowired
  private VccClient vccClient;

  @Override
  public void prepare(IntegrationAuthentication integrationAuthentication) {
    String vcToken = integrationAuthentication.getAuthParameter("vc_token");
    String vcCode = integrationAuthentication.getAuthParameter("vc_code");
    //驗證驗證碼
    Result<Boolean> result = vccClient.validate(vcToken, vcCode, null);
    if (!result.getData()) {
      throw new OAuth2Exception("驗證碼錯誤");
    }
  }

  @Override
  public boolean support(IntegrationAuthentication integrationAuthentication) {
    return VERIFICATION_CODE_AUTH_TYPE.equals(integrationAuthentication.getAuthType());
  }
}

VerificationCodeIntegrationAuthenticator繼承UsernamePasswordAuthenticator，因為其只是需要在prepare方法中驗證驗證碼是否正確，獲取用戶還是用過用戶名密碼的方式獲取。但是需要認(rèn)證類型為"vc"才會處理
接下來來看下短信驗證碼登錄是如何處理的：

@Component
public class SmsIntegrationAuthenticator extends AbstractPreparableIntegrationAuthenticator implements ApplicationEventPublisherAware {

  @Autowired
  private UcClient ucClient;

  @Autowired
  private VccClient vccClient;

  @Autowired
  private PasswordEncoder passwordEncoder;

  private ApplicationEventPublisher applicationEventPublisher;

  private final static String SMS_AUTH_TYPE = "sms";

  @Override
  public UserVO authenticate(IntegrationAuthentication integrationAuthentication) {

    //獲取密碼，實際值是驗證碼
    String password = integrationAuthentication.getAuthParameter("password");
    //獲取用戶名，實際值是手機號
    String username = integrationAuthentication.getUsername();
    //發(fā)布事件，可以監(jiān)聽事件進行自動注冊用戶
    this.applicationEventPublisher.publishEvent(new SmsAuthenticateBeforeEvent(integrationAuthentication));
    //通過手機號碼查詢用戶
    UserVO userVo = this.ucClient.findUserByPhoneNumber(username);
    if (userVo != null) {
      //將密碼設(shè)置為驗證碼
      userVo.setPassword(passwordEncoder.encode(password));
      //發(fā)布事件，可以監(jiān)聽事件進行消息通知
      this.applicationEventPublisher.publishEvent(new SmsAuthenticateSuccessEvent(integrationAuthentication));
    }
    return userVo;
  }

  @Override
  public void prepare(IntegrationAuthentication integrationAuthentication) {
    String smsToken = integrationAuthentication.getAuthParameter("sms_token");
    String smsCode = integrationAuthentication.getAuthParameter("password");
    String username = integrationAuthentication.getAuthParameter("username");
    Result<Boolean> result = vccClient.validate(smsToken, smsCode, username);
    if (!result.getData()) {
      throw new OAuth2Exception("驗證碼錯誤或已過期");
    }
  }

  @Override
  public boolean support(IntegrationAuthentication integrationAuthentication) {
    return SMS_AUTH_TYPE.equals(integrationAuthentication.getAuthType());
  }

  @Override
  public void setApplicationEventPublisher(ApplicationEventPublisher applicationEventPublisher) {
    this.applicationEventPublisher = applicationEventPublisher;
  }
}

SmsIntegrationAuthenticator會對登錄的短信驗證碼進行預(yù)處理，判斷其是否非法，如果是非法的則直接中斷登錄。如果通過預(yù)處理則在獲取用戶信息的時候通過手機號去獲取用戶信息，并將密碼重置，以通過后續(xù)的密碼校驗。

總結(jié)

在這個解決方案中，主要是使用責(zé)任鏈和適配器的設(shè)計模式來解決集成登錄的問題，提高了可擴展性，并對spring的源碼無污染。如果還要繼承其他的登錄，只需要實現(xiàn)自定義的IntegrationAuthenticator就可以。
