Spring Security OAuth 默认提供OAuth2.0 的四大基本授权方式(authorization_code\\implicit\\password\\client_credential),除此之外我们也能够自定义授权方式。

Spring Security OAuth 默认提供OAuth2.0 的四大基本授权方式(authorization_code\implicit\password\client_credential),除此之外我们也能够自定义授权方式。

先了解一下Spring Security OAuth提供的两个默认 Endpoints,一个是AuthorizationEndpoint,这个是仅用于授权码(authorization_code)和简化(implicit)模式的。另外一个是TokenEndpoint,用于OAuth2授权时下发Token,根据授予类型(GrantType)的不同而执行不同的验证方式。

OAuth2协议这里就不做过多介绍了,比较重要的一点是理解认证中各个角色的作用,以及认证的目的(获取用户信息或是具备使用API的权限)。例如在authorization_code模式下,用户(User)在认证服务的网站上进行登录,网站跳转回第三方应用(Client),第三方应用通过Secret和Code换取Token后向资源服务请求用户信息;而在client_credential模式下,第三方应用通过Secret直接获得Token后可以直接利用其访问资源API。所以我们应该根据实际的情景选择适合的认证模式。

对于手机验证码的认证模式,我们首先提出短信验证的通常需求:

  • 每发一次验证码只能尝试验证5次,防止暴力破解
  • 限制验证码发送频率,单个用户(这里简单使用手机号区分)1分钟1条,24小时x条
  • 限制验证码有效期,15分钟

我们根据业务需求构造出对应的模型:

@Data
public class SmsVerificationModel {

  /**
   * 手机号
   */
  private String phoneNumber;

  /**
   * 验证码
   */
  private String captcha;

  /**
   * 本次验证码验证失败次数,防止暴力尝试
   */
  private Integer failCount;

  /**
   * 该user当日尝试次数,防止滥发短信
   */
  private Integer dailyCount;

  /**
   * 限制短信发送频率和实现验证码有效期
   */
  private Date lastSentTime;

  /**
   * 是否验证成功
   */
  private Boolean verified = false;

}

我们预想的认证流程:

接下来要对Spring Security OAuth进行定制,这里直接仿照一个比较相似的password模式,首先需要编写一个新的TokenGranter,处理sms类型下的TokenRequest,这个SmsTokenGranter会生成SmsAuthenticationToken,并将AuthenticationToken交由SmsAuthenticationProvider进行验证,验证成功后生成通过验证的SmsAuthenticationToken,完成Token的颁发。

public class SmsTokenGranter extends AbstractTokenGranter {
  private static final String GRANT_TYPE = "sms";

  private final AuthenticationManager authenticationManager;

  public SmsTokenGranter(AuthenticationManager authenticationManager, AuthorizationServerTokenServices tokenServices,
              ClientDetailsService clientDetailsService, OAuth2RequestFactory requestFactory){
    super(tokenServices, clientDetailsService, requestFactory, GRANT_TYPE);
    this.authenticationManager = authenticationManager;
  }

  @Override
  protected OAuth2Authentication getOAuth2Authentication(ClientDetails client, TokenRequest tokenRequest) {
    Map<String, String> parameters = new LinkedHashMap<>(tokenRequest.getRequestParameters());
    String phone = parameters.get("phone");
    String code = parameters.get("code");

    Authentication userAuth = new SmsAuthenticationToken(phone, code);
    try {
      userAuth = authenticationManager.authenticate(userAuth);
    }
    catch (AccountStatusException ase) {
      throw new InvalidGrantException(ase.getMessage());
    }
    catch (BadCredentialsException e) {
      throw new InvalidGrantException(e.getMessage());
    }
    if (userAuth == null || !userAuth.isAuthenticated()) {
      throw new InvalidGrantException("Could not authenticate user: " + username);
    }

    OAuth2Request storedOAuth2Request = getRequestFactory().createOAuth2Request(client, tokenRequest);
    return new OAuth2Authentication(storedOAuth2Request, userAuth);
  }
}

对应的SmsAuthenticationToken,其中一个构造方法是认证后的。

public class SmsAuthenticationToken extends AbstractAuthenticationToken {

  private final Object principal;
  private Object credentials;

  public SmsAuthenticationToken(Object principal, Object credentials) {
    super(null);
    this.credentials = credentials;
    this.principal = principal;
  }

  public SmsAuthenticationToken(Object principal, Object credentials,
                        Collection<? extends GrantedAuthority> authorities) {
    super(authorities);
    this.principal = principal;
    this.credentials = credentials;
    // 表示已经认证
    super.setAuthenticated(true);
  }
 ...
}

SmsAuthenticationProvider是仿照AbstractUserDetailsAuthenticationProvider编写的,这里仅仅列出核心部分。

public class SmsAuthenticationProvider implements AuthenticationProvider {

  @Override
  public Authentication authenticate(Authentication authentication)
      throws AuthenticationException {
   String username = authentication.getName();
   UserDetails user = retrieveUser(username);

   preAuthenticationChecks.check(user);
   String phoneNumber = authentication.getPrincipal().toString();
   String code = authentication.getCredentials().toString();
   // 尝试从Redis中取出Model
   SmsVerificationModel verificationModel =
        Optional.ofNullable(
            redisService.get(SMS_REDIS_PREFIX + phoneNumber, SmsVerificationModel.class))
        .orElseThrow(() -> new BusinessException(OAuthError.SMS_VERIFY_BEFORE_SEND));
  // 判断短信验证次数
   Optional.of(verificationModel).filter(x -> x.getFailCount() < SMS_VERIFY_FAIL_MAX_TIMES)
        .orElseThrow(() -> new BusinessException(OAuthError.SMS_VERIFY_COUNT_EXCEED));

   Optional.of(verificationModel).map(SmsVerificationModel::getLastSentTime)
        // 验证码发送15分钟内有效,等价于发送时间加上15分钟晚于当下
        .filter(x -> DateUtils.addMinutes(x,15).after(new Date()))
        .orElseThrow(() -> new BusinessException(OAuthError.SMS_CODE_EXPIRED));

   verificationModel.setVerified(Objects.equals(code, verificationModel.getCaptcha()));
   verificationModel.setFailCount(verificationModel.getFailCount() + 1);

   redisService.set(SMS_REDIS_PREFIX + phoneNumber, verificationModel, 1, TimeUnit.DAYS);

   if(!verificationModel.getVerified()){
      throw new BusinessException(OAuthError.SmsCodeWrong);
   }

    postAuthenticationChecks.check(user);

    return createSuccessAuthentication(user, authentication, user);
  }
  ...

接下来要通过配置启用我们定制的类,首先配置AuthorizationServerEndpointsConfigurer,添加上我们的TokenGranter,然后是AuthenticationManagerBuilder,添加我们的AuthenticationProvider。

@Configuration
@EnableAuthorizationServer
public class OAuth2Config extends AuthorizationServerConfigurerAdapter {

  @Override
  public void configure(AuthorizationServerSecurityConfigurer security) throws Exception {
    security
        .passwordEncoder(passwordEncoder)
        .checkTokenAccess("isAuthenticated()")
        .tokenKeyAccess("permitAll()")
        // 允许使用Query字段验证客户端,即client_id/client_secret 能够放在查询参数中
        .allowFormAuthenticationForClients();
  }

  @Override
  public void configure(AuthorizationServerEndpointsConfigurer endpoints) throws Exception {

    endpoints.authenticationManager(authenticationManager)
        .userDetailsService(userDetailsService)
        .tokenStore(tokenStore);
    List<TokenGranter> tokenGranters = new ArrayList<>();

    tokenGranters.add(new AuthorizationCodeTokenGranter(endpoints.getTokenServices(), endpoints.getAuthorizationCodeServices(), clientDetailsService,
        endpoints.getOAuth2RequestFactory()));
  ...
    tokenGranters.add(new SmsTokenGranter(authenticationManager, endpoints.getTokenServices(),
        clientDetailsService, endpoints.getOAuth2RequestFactory()));

    endpoints.tokenGranter(new CompositeTokenGranter(tokenGranters));
  }

}
@EnableWebSecurity
@Configuration
public class SecurityConfig extends WebSecurityConfigurerAdapter {
 ...
  @Override
  protected void configure(AuthenticationManagerBuilder auth) {
    auth.authenticationProvider(daoAuthenticationProvider());
  }

  @Bean
  public AuthenticationProvider smsAuthenticationProvider(){
    SmsAuthenticationProvider smsAuthenticationProvider = new SmsAuthenticationProvider();
    smsAuthenticationProvider.setUserDetailsService(userDetailsService);
    smsAuthenticationProvider.setSmsAuthService(smsAuthService);
    return smsAuthenticationProvider;
  }
}

那么短信验证码授权的部分就到这里了,最后还有一个发送短信的接口,这里就不展示了。

最后测试一下,curl --location --request POST 'http://localhost:8080/oauth/token?grant_type=sms&client_id=XXX&phone=手机号&code=验证码' ,成功。

{
  "access_token": "39bafa9a-7e5b-4ba4-9eda-e307ac98aad1",
  "token_type": "bearer",
  "expires_in": 3599,
  "scope": "ALL"
}
