Java使用AJ-Captcha滑动验证码

文档地址： 文档地址

1、验证码类型包括两种

滑块验证码

文字验证码

2、项目引入AJ-Captcha

2.1 添加依赖

<dependency>
    <groupId>com.anji-plus</groupId>
    <artifactId>captcha</artifactId>
    <version>1.3.0</version>
</dependency>

后端SpringBoot

 @Resource
    private CaptchaService captchaService;

    @PostMapping("/get") // 获取图片
    public ResponseModel get(@RequestBody CaptchaVO data, HttpServletRequest request) {
        assert request.getRemoteHost()!=null;
        data.setBrowserInfo(getRemoteId(request));
        return captchaService.get(data);
    }

    @PostMapping("/check") // 进行校验
    public ResponseModel check(@RequestBody CaptchaVO data, HttpServletRequest request) {
        data.setBrowserInfo(getRemoteId(request));
        return captchaService.check(data);
    }

    @PostMapping("/verify") // 二次校验
    public ResponseModel verify(@RequestBody CaptchaVO data, HttpServletRequest request) {
        return captchaService.verification(data);
    }

    public static final String getRemoteId(HttpServletRequest request) {
        String xfwd = request.getHeader("X-Forwarded-For");
        String ip = getRemoteIpFromXfwd(xfwd);
        String ua = request.getHeader("user-agent");
        if (StringUtils.isNotBlank(ip)) {
            return ip + ua;
        }
        return request.getRemoteAddr() + ua;
    }

    private static String getRemoteIpFromXfwd(String xfwd) {
        if (StringUtils.isNotBlank(xfwd)) {
            String[] ipList = xfwd.split(",");
            return StringUtils.trim(ipList[0]);
        }
        return null;
    }

1. 获取验证码接口：http://:/captcha/get

入参：

{
	"captchaType": "blockPuzzle",  //验证码类型 clickWord
	"clientUid": "唯一标识"  //客户端UI组件id,组件初始化时设置一次，UUID（非必传参数）
}

回参：

{
    "repCode": "0000",
    "repData": {
        "originalImageBase64": "底图base64",
        "point": {    //默认不返回的，校验的就是该坐标信息，允许误差范围
            "x": 205,
            "y": 5
        },
        "jigsawImageBase64": "滑块图base64",
        "token": "71dd26999e314f9abb0c635336976635", //一次校验唯一标识
        "secretKey": "16位随机字符串", //aes秘钥，开关控制，前端根据此值决定是否加密
        "result": false,
        "opAdmin": false
    },
    "success": true,
    "error": false
}

2. 核对验证码接口接口：http://:/captcha/check

入参：

{
	 "captchaType": "blockPuzzle",
	 "pointJson": "QxIVdlJoWUi04iM+65hTow==",  //aes加密坐标信息
	 "token": "71dd26999e314f9abb0c635336976635"  //get请求返回的token
}

回参：

{
    "repCode": "0000",
    "repData": {
        "captchaType": "blockPuzzle",
        "token": "71dd26999e314f9abb0c635336976635",
        "result": true,
        "opAdmin": false
    },
    "success": true,
    "error": false
}

使用自定义Redis

@Service
@Slf4j
public class CaptchaCacheServiceRedisImpl implements CaptchaCacheService {

    private static final String REDIS = "redis";

    @Autowired
    private RedisService redisService;

    @Override
    public void set(String key, String value, long expiresInSeconds) {
        redisService.set(CacheKeyConstants.USER_IMG_VERIFICATION_CODE_PREFIX + key, value, expiresInSeconds);
    }

    @Override
    public boolean exists(String key) {
        return redisService.hasKey(CacheKeyConstants.USER_IMG_VERIFICATION_CODE_PREFIX + key);
    }

    @Override
    public void delete(String key) {
        redisService.delete(CacheKeyConstants.USER_IMG_VERIFICATION_CODE_PREFIX + key);
    }

    @Override
    public String get(String key) {
        return redisService.get(CacheKeyConstants.USER_IMG_VERIFICATION_CODE_PREFIX + key);
    }

    @Override
    public String type() {
        return REDIS;
    }
}
