极验验证（滑动验证）的使用

极验验证目录

一、样例
二、注册账号
三、获取ID
四、极验官方文档（参考）
五、SpringBoot集成极验
- 5.1、maven依赖（可能有些需要自己去导，个人的包依赖太多不好全部放上来，核心就这两个）
- 5.2、yml配置文件
- 5.3、util类（读本地ip）
- 5.4、读取配置类
- 5.5、获取极验的第一次数据包
- - 5.5.1、在资源服务器里面放行路径
  - 5.5.2、添加控制器 GeetestController
  - 5.5.3、在gateway网关里面添加 CorsConfig

一、样例

二、注册账号

极验验证官网

在表单里面填写真实信息，客服会在 24h 联系你进行审核，审核通过后，会发送这样的邮件到你的邮箱。

点击邮箱里面提供的注册地址即可完成注册。注册成功后，进行登录：

三、获取ID

填写基本信息：

创建成功后：

点击 ID:

点击查看部署指引：

都勾选成功后，点击确认：

获取到了 ID 和 KEY:

记录 ID 和 KEY:

ID               上面获得到的id
KEY             上面获取到的value

四、极验官方文档（参考）

文档地址:
https://docs.geetest.com/sensebot/start/
服务端：
https://docs.geetest.com/sensebot/deploy/server/java#%E9%85%8D%E7%BD %AE%E5%AF%86%E9%92%A5
Web 端：
https://docs.geetest.com/sensebot/deploy/client/web

五、SpringBoot集成极验

5.1、maven依赖（可能有些需要自己去导，个人的包依赖太多不好全部放上来，核心就这两个）

   <!--json的依赖--><dependency><groupId>org.json</groupId><artifactId>json</artifactId><version>20171018</version></dependency><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-data-redis</artifactId></dependency><dependency><groupId>org.projectlombok</groupId><artifactId>lombok</artifactId><version>1.18.12</version></dependency>

5.2、yml配置文件

spring:redis:host: redis-server      #自己redis的ip，此处我做了ip映射port: 6380password: 123456
geetest:geetest-id: 上面获得到的idgeetest-key: 上面获取到的value

5.3、util类（读本地ip）

package com.zhz.util;import javax.servlet.http.HttpServletRequest;/*** 获取本地ip地址*/
public class IpUtil {public static String getIpAddr(HttpServletRequest request) {String ip = request.getHeader("X-Forwarded-For");if (ip == null || ip.length() == 0 || "unknown".equalsIgnoreCase(ip)) {if (ip == null || ip.length() == 0 || "unknown".equalsIgnoreCase(ip)) {ip = request.getHeader("Proxy-Client-IP");}if (ip == null || ip.length() == 0 || "unknown".equalsIgnoreCase(ip)) {}if (ip == null || ip.length() == 0 || "unknown".equalsIgnoreCase(ip)) {ip = request.getHeader("HTTP_CLIENT_IP");}if (ip == null || ip.length() == 0 || "unknown".equalsIgnoreCase(ip)) {ip = request.getHeader("HTTP_X_FORWARDED_FOR");}if (ip == null || ip.length() == 0 || "unknown".equalsIgnoreCase(ip)) {ip = request.getHeader("HTTP_X_CONNECTING_IP");}if (ip == null || ip.length() == 0 || "unknown".equalsIgnoreCase(ip)) {ip = request.getRemoteAddr();}} else if (ip.length() > 15) {String[] ips = ip.split(",");for (int index = 0; index < ips.length; index++) {String strIp = (String) ips[index];if (!("unknown".equalsIgnoreCase(strIp))) {ip = strIp;break;}}}return ip;}
}

5.4、读取配置类

package com.zhz.config;import lombok.Data;
import org.springframework.boot.context.properties.ConfigurationProperties;/*** @author ：zhz* @date ：Created in 2021/01/02* @version: V1.0* @slogan: 天下风云出我辈，一入代码岁月催* @description: 极验验证的ID和Key配置**/
@Data
@ConfigurationProperties(prefix = "geetest")
public class GeetestProperties {/*** 极验的 ID*/private String geetestId;/*** 极验的 key*/private String geetestKey;

}

package com.zhz.geetest;/*** sdk lib包的返回结果信息。*/
public class GeetestLibResult {/*** 成功失败的标识码，1表示成功，0表示失败*/private int status = 0;/*** 返回数据，json格式*/private String data = "";/*** 备注信息，如异常信息等*/private String msg = "";public void setStatus(int status) {this.status = status;}public int getStatus() {return status;}public void setData(String data) {this.data = data;}public String getData() {return data;}public void setMsg(String msg) {this.msg = msg;}public String getMsg() {return msg;}public void setAll(int status, String data, String msg) {this.setStatus(status);this.setData(data);this.setMsg(msg);}@Overridepublic String toString() {return String.format("GeetestLibResult{status=%s, data=%s, msg=%s}", this.status, this.data, this.msg);}
}

5.5、获取极验的第一次数据包

5.5.1、在资源服务器里面放行路径

我用的jwt+auth2.0，你们自己去放行路径--》"/gt/register"

5.5.2、添加控制器 GeetestController

package com.zhz.controller;import com.zhz.geetest.GeetestLib;
import com.zhz.geetest.GeetestLibResult;
import com.zhz.model.R;
import com.zhz.util.IpUtil;
import io.swagger.annotations.Api;
import io.swagger.annotations.ApiImplicitParam;
import io.swagger.annotations.ApiImplicitParams;

import org.springframework.data.redis.core.RedisTemplate;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
import org.springframework.web.context.request.RequestContextHolder;
import org.springframework.web.context.request.ServletRequestAttributes;import java.util.HashMap;
import java.util.Map;
import java.util.concurrent.TimeUnit;/*** @author ：zhz* @date ：Created in 2021/01/02* @version: V1.0* @slogan: 天下风云出我辈，一入代码岁月催* @description:**/
@RestController
@RequestMapping("/gt")
public class GeetestController {@Autowiredprivate GeetestLib geetestLib;@Autowiredprivate RedisTemplate<String, Object> redisTemplate;@GetMapping("/register")public R<String> register(String uuid) {String digestmod = "md5";Map<String, String> paramMap = new HashMap<String, String>();paramMap.put("digestmod", digestmod);paramMap.put("user_id", uuid);paramMap.put("client_type", "web");ServletRequestAttributes servletRequestAttributes = (ServletRequestAttributes) RequestContextHolder.getRequestAttributes();paramMap.put("ip_address", IpUtil.getIpAddr(servletRequestAttributes.getRequest()));//ip地址GeetestLibResult result = geetestLib.register(digestmod, paramMap); // 极验服务器交互// 将结果状态写到session中，此处register接口存入session，后续validate接口会取出使用// 注意，此demo应用的session是单机模式，格外注意分布式环境下session的应用redisTemplate.opsForValue().set(GeetestLib.GEETEST_SERVER_STATUS_SESSION_KEY, result.getStatus(), 180, TimeUnit.SECONDS);
//        request.getSession().setAttribute( result.getStatus());redisTemplate.opsForValue().set(GeetestLib.GEETEST_SERVER_USER_KEY + ":" + uuid, uuid, 180, TimeUnit.SECONDS);
//        request.getSession().setAttribute("userId", userId);// 注意，不要更改返回的结构和值类型return R.ok(result.getData());}
}

5.5.3、在gateway网关里面添加 CorsConfig

package com.zhz.config;import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.cors.CorsConfiguration;
import org.springframework.web.cors.reactive.CorsWebFilter;

@Configuration
public class CorsConfig {@Beanpublic CorsWebFilter corsWebFilter(){CorsConfiguration corsConfiguration=new CorsConfiguration();corsConfiguration.addAllowedHeader("*");corsConfiguration.addAllowedOrigin("*");corsConfiguration.addAllowedMethod("*");UrlBasedCorsConfigurationSource urlBasedCorsConfigurationSource=new UrlBasedCorsConfigurationSource();urlBasedCorsConfigurationSource.registerCorsConfiguration("/**",corsConfiguration);return new CorsWebFilter(urlBasedCorsConfigurationSource);}
}
