SpringCloud微服务实战——搭建企业级开发框架（二十六）：自定义扩展OAuth2实现短信验证码登录

现在手机验证码登录似乎是每个网站必备的功能，OAuth2支持扩展自定义授权模式，前面介绍了如何在系统集成短信通知服务，这里我们进行OAuth2的授权模式自定义扩展，使系统支持短信验证码登录。

1、在gitegg-oauth中新增SmsCaptchaTokenGranter 自定义短信验证码令牌授权处理类

/**
 * 短信验证码模式
 */
public class SmsCaptchaTokenGranter extends AbstractTokenGranter {

    private static final String GRANT_TYPE = "sms_captcha";

    private final AuthenticationManager authenticationManager;

    private UserDetailsService userDetailsService;

    private IUserFeign userFeign;

    private ISmsFeign smsFeign;

    private RedisTemplate redisTemplate;

    private CaptchaService captchaService;

    private String captchaType;

    public SmsCaptchaTokenGranter(AuthenticationManager authenticationManager,
                                  AuthorizationServerTokenServices tokenServices, ClientDetailsService clientDetailsService,
                                  OAuth2RequestFactory requestFactory, RedisTemplate redisTemplate, IUserFeign userFeign, ISmsFeign smsFeign, CaptchaService captchaService,
                                  UserDetailsService userDetailsService, String captchaType) {
        this(authenticationManager, tokenServices, clientDetailsService, requestFactory, GRANT_TYPE);
        this.redisTemplate = redisTemplate;
        this.captchaService = captchaService;
        this.captchaType = captchaType;
        this.smsFeign = smsFeign;
        this.userFeign = userFeign;
        this.userDetailsService = userDetailsService;
    }

    protected SmsCaptchaTokenGranter(AuthenticationManager authenticationManager,
                                  AuthorizationServerTokenServices tokenServices, ClientDetailsService clientDetailsService,
                                  OAuth2RequestFactory requestFactory, String grantType) {
        super(tokenServices, clientDetailsService, requestFactory, grantType);
        this.authenticatiOnManager= authenticationManager;
    }

    @Override
    protected OAuth2Authentication getOAuth2Authentication(ClientDetails client, TokenRequest tokenRequest) {

        Map parameters = new LinkedHashMap<>(tokenRequest.getRequestParameters());
        // 获取验证码类型
        String captchaType = parameters.get(CaptchaConstant.CAPTCHA_TYPE);
        // 判断传入的验证码类型和系统配置的是否一致
        if (!StringUtils.isEmpty(captchaType) && !captchaType.equals(this.captchaType)) {
            throw new UserDeniedAuthorizationException(ResultCodeEnum.INVALID_CAPTCHA_TYPE.getMsg());
        }
        if (CaptchaConstant.IMAGE_CAPTCHA.equalsIgnoreCase(captchaType)) {
            // 图片验证码验证
            String captchaKey = parameters.get(CaptchaConstant.CAPTCHA_KEY);
            String captchaCode = parameters.get(CaptchaConstant.CAPTCHA_CODE);
            // 获取验证码
            String redisCode = (String)redisTemplate.opsForValue().get(CaptchaConstant.IMAGE_CAPTCHA_KEY + captchaKey);
            // 判断验证码
            if (captchaCode == null || !captchaCode.equalsIgnoreCase(redisCode)) {
                throw new UserDeniedAuthorizationException(ResultCodeEnum.INVALID_CAPTCHA.getMsg());
            }
        } else {
            // 滑动验证码验证
            String captchaVerification = parameters.get(CaptchaConstant.CAPTCHA_VERIFICATION);
            CaptchaVO captchaVO = new CaptchaVO();
            captchaVO.setCaptchaVerification(captchaVerification);
            ResponseModel respOnseModel= captchaService.verification(captchaVO);
            if (null == responseModel || !RepCodeEnum.SUCCESS.getCode().equals(responseModel.getRepCode())) {
                throw new UserDeniedAuthorizationException(ResultCodeEnum.INVALID_CAPTCHA.getMsg());
            }
        }

        String phOneNumber= parameters.get(TokenConstant.PHONE_NUMBER);
        String smsCode = parameters.get(TokenConstant.SMS_CODE);
        String code = parameters.get(TokenConstant.CODE);
        // Protect from downstream leaks of password
        parameters.remove(TokenConstant.CODE);

        Result checkResult = smsFeign.checkSmsVerificationCode(smsCode, phoneNumber, code);

        if (null == checkResult || !checkResult.getData()) {
            throw new InvalidGrantException(("Could not authenticate user: " + phoneNumber));
        }

        UserDetails userDetails = this.userDetailsService.loadUserByUsername(phoneNumber);

        Authentication userAuth = new UsernamePasswordAuthenticationToken(userDetails, null, userDetails.getAuthorities());
        ((AbstractAuthenticationToken)userAuth).setDetails(parameters);

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

}

2、自定义GitEggTokenGranter，支持多种token模式

/**
 * 自定义token
 */
public class GitEggTokenGranter {

    /**
     * 自定义tokenGranter
     */
    public static TokenGranter getTokenGranter(final AuthenticationManager authenticationManager,
                                               final AuthorizationServerEndpointsConfigurer endpoints, RedisTemplate redisTemplate, IUserFeign userFeign,
                                               ISmsFeign smsFeign, CaptchaService captchaService, UserDetailsService userDetailsService, String captchaType) {
        // 默认tokenGranter集合
        List granters = new ArrayList<>(Collections.singletonList(endpoints.getTokenGranter()));
        // 增加验证码模式
        granters.add(new CaptchaTokenGranter(authenticationManager, endpoints.getTokenServices(),
            endpoints.getClientDetailsService(), endpoints.getOAuth2RequestFactory(), redisTemplate, captchaService,
            captchaType));
        // 增加短信验证码模式
        granters.add(new SmsCaptchaTokenGranter(authenticationManager, endpoints.getTokenServices(),
                endpoints.getClientDetailsService(), endpoints.getOAuth2RequestFactory(), redisTemplate, userFeign, smsFeign, captchaService,
                userDetailsService, captchaType));
        // 组合tokenGranter集合
        return new CompositeTokenGranter(granters);
    }

}

3、GitEggOAuthController中增加获取短信验证码的方法

    @ApiOperation("发送短信验证码")
    @PostMapping("/sms/captcha/send")
    public Result sendSmsCaptcha(@RequestBody SmsVerificationDTO smsVerificationDTO) {
        Result sendResult = smsFeign.sendSmsVerificationCode(smsVerificationDTO.getSmsCode(), smsVerificationDTO.getPhoneNumber());
        return sendResult;
    }

4、前端页面增加短信验证码登录方式

getCaptcha (e) {
      e.preventDefault()
      const { form: { validateFields }, state } = this

      validateFields(['phoneNumber'], { force: true }, (err, values) => {
        if (!err) {
          state.smsSendBtn = true

          const interval = window.setInterval(() => {
            if (state.time-- <= 0) {
              state.time = 60
              state.smsSendBtn = false
              window.clearInterval(interval)
            }
          }, 1000)

          const hide = this.$message.loading('验证码发送中..', 0)
          getSmsCaptcha({ phoneNumber: values.phoneNumber, smsCode: 'aliLoginCode' }).then(res => {
            setTimeout(hide, 2500)
            this.$notification['success']({
              message: '提示',
              description: '验证码获取成功，您的验证码为：' + res.result.captcha,
              duration: 8
            })
          }).catch(err => {
            setTimeout(hide, 1)
            clearInterval(interval)
            state.time = 60
            state.smsSendBtn = false
            this.requestFailed(err)
          })
        }
      })
    },
    stepCaptchaSuccess () {
      this.loginSuccess()
    },
    stepCaptchaCancel () {
      this.Logout().then(() => {
        this.loginBtn = false
        this.stepCaptchaVisible = false
      })
    },

5、通过短信验证码登录界面
