SpringCloud微服务实战——搭建企业级开发框架（二十四）（集成行为验证码和图片验证码实现登录功能）
随着近几年技术的发展，人们对于系统安全性和用户体验的要求越来越高，大多数网站系统都逐渐采用行为验证码来代替图片验证码。GitEgg-Cloud集成了开源行为验证码组件和图片验证码，并在系统中添加可配置项来选择具体使用哪种验证码。
- AJ-Captcha：行为验证码
- EasyCaptcha: 图片验证码
1.2.7 1.6.2
com.github.anji-plus
captcha-spring-boot-starter
${captcha.version}
com.github.whvcse
easy-captcha
${easy.captcha.version}
2、新建gitegg-platform-captcha工程，用于配置及自定义方法，行为验证码用到缓存是需要自定义实现CaptchaCacheService，自定义类CaptchaCacheServiceRedisImpl:
public class CaptchaCacheServiceRedisImpl implements CaptchaCacheService {@Override
public String type() {
return "redis";
}@Autowired
private StringRedisTemplate stringRedisTemplate;
@Override
public void set(String key, String value, long expiresInSeconds) {
stringRedisTemplate.opsForValue().set(key, value, expiresInSeconds, TimeUnit.SECONDS);
}@Override
public boolean exists(String key) {
return stringRedisTemplate.hasKey(key);
}@Override
public void delete(String key) {
stringRedisTemplate.delete(key);
}@Override
public String get(String key) {
return stringRedisTemplate.opsForValue().get(key);
}
}
3、在gitegg-platform-captcha的resources目录新建META-INF.services文件夹，参考resource/META-INF/services中的写法。
com.gitegg.platform.captcha.service.impl.CaptchaCacheServiceRedisImpl
4、在GitEgg-Cloud下的gitegg-oauth中增加CaptchaTokenGranter自定义验证码令牌授权处理类
/**
* 验证码模式
*/
public class CaptchaTokenGranter extends AbstractTokenGranter {private static final String GRANT_TYPE = "captcha";
private final AuthenticationManager authenticationManager;
private RedisTemplate redisTemplate;
private CaptchaService captchaService;
private String captchaType;
public CaptchaTokenGranter(AuthenticationManager authenticationManager,
AuthorizationServerTokenServices tokenServices, ClientDetailsService clientDetailsService,
OAuth2RequestFactory requestFactory, RedisTemplate redisTemplate, CaptchaService captchaService,
String captchaType) {
this(authenticationManager, tokenServices, clientDetailsService, requestFactory, GRANT_TYPE);
this.redisTemplate = redisTemplate;
this.captchaService = captchaService;
this.captchaType = captchaType;
}protected CaptchaTokenGranter(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);
String slidingCaptchaType = parameters.get(CaptchaConstant.SLIDING_CAPTCHA_TYPE);
CaptchaVO captchaVO = new CaptchaVO();
captchaVO.setCaptchaVerification(captchaVerification);
captchaVO.setCaptchaType(slidingCaptchaType);
ResponseModel responseModel = captchaService.verification(captchaVO);
if (null == responseModel || !RepCodeEnum.SUCCESS.getCode().equals(responseModel.getRepCode())) {
throw new UserDeniedAuthorizationException(ResultCodeEnum.INVALID_CAPTCHA.getMsg());
}
}String username = parameters.get(TokenConstant.USER_NAME);
String password = parameters.get(TokenConstant.PASSWORD);
// Protect from downstream leaks of password
parameters.remove(TokenConstant.PASSWORD);
Authentication userAuth = new UsernamePasswordAuthenticationToken(username, password);
((AbstractAuthenticationToken)userAuth).setDetails(parameters);
try {
userAuth = authenticationManager.authenticate(userAuth);
} catch (AccountStatusException | BadCredentialsException ase) {
// covers expired, locked, disabled cases (mentioned in section 5.2, draft 31)
throw new InvalidGrantException(ase.getMessage());
}
// If the username/password are wrong the spec says we should send 400/invalid grantif (userAuth == null || !userAuth.isAuthenticated()) {
throw new InvalidGrantException("Could not authenticate user: " + username);
}OAuth2Request storedOAuth2Request = getRequestFactory().createOAuth2Request(client, tokenRequest);
return new OAuth2Authentication(storedOAuth2Request, userAuth);
}
}
5、gitegg-oauth中GitEggOAuthController新增获取验证码的方法
@Value("${captcha.type}")
private String captchaType;
@ApiOperation("获取系统配置的验证码类型")
@GetMapping("/captcha/type")
public Result captchaType() {
return Result.data(captchaType);
}@ApiOperation("生成滑动验证码")
@PostMapping("/captcha")
public Result captcha(@RequestBody CaptchaVO captchaVO) {
ResponseModel responseModel = captchaService.get(captchaVO);
return Result.data(responseModel);
}@ApiOperation("滑动验证码验证")
@PostMapping("/captcha/check")
public Result captchaCheck(@RequestBody CaptchaVO captchaVO) {
ResponseModel responseModel = captchaService.check(captchaVO);
return Result.data(responseModel);
}@ApiOperation("生成图片验证码")
@RequestMapping("/captcha/image")
public Result captchaImage() {
SpecCaptcha specCaptcha = new SpecCaptcha(130, 48, 5);
String captchaCode = specCaptcha.text().toLowerCase();
String captchaKey = UUID.randomUUID().toString();
// 存入redis并设置过期时间为5分钟
redisTemplate.opsForValue().set(CaptchaConstant.IMAGE_CAPTCHA_KEY + captchaKey, captchaCode, GitEggConstant.Number.FIVE,
TimeUnit.MINUTES);
ImageCaptcha imageCaptcha = new ImageCaptcha();
imageCaptcha.setCaptchaKey(captchaKey);
imageCaptcha.setCaptchaImage(specCaptcha.toBase64());
// 将key和base64返回给前端
return Result.data(imageCaptcha);
}
6、将滑动验证码提供的前端页面verifition目录copy到我们前端工程的compoonents目录，修改Login.vue，增加验证码

grantType: 'password',
loginCaptchaType: 'sliding',
slidingCaptchaType: 'blockPuzzle',
loginErrorMsg: '用户名或密码错误',

} else {

// 滑动验证码二次校验并提交登录
verifySuccess (params) {

}
7、在Nacos中增加配置项，默认使用行为验证码
#验证码配置
captcha:
#验证码的类型 sliding: 滑动验证码 image: 图片验证码
type: sliding
