极验是一种利用生物特征与人工智能技术解决人机交互安全问题的技术，旨在解决安全验证问题，例如：账号登录、短信验证、批量注册等，目前极验、网易易盾比较出众。
在这里主要使用的极验Geetest和springboot 框架整合。
1.首先到极验官网注册账号获取ID和KEY，这里赘述。
2.到极验官网下载，使用SDK，点击下载，如果你使用时Git工具，
#git clone https://github.com/GeeTeam/gt3-java-sdk.git
3.引入SDK到Springboot项目中
将sdk项目目录下的GeetestLib.java文件拷入您的项目Untils目录中，代码如下：
package com.blog.utils;
import org.json.JSONException;
import org.json.JSONObject;
import java.io.IOException;
import java.io.InputStream;
import java.io.OutputStreamWriter;
import java.net.HttpURLConnection;
import java.net.URL;
import java.security.MessageDigest;
import java.security.NoSuchAlgorithmException;
import java.util.HashMap;

}
re_md5 = buf.toString();
} catch (NoSuchAlgorithmException e) {
e.printStackTrace();
}
return re_md5;
}
}
4.配置密钥，修改请求参数
配置密钥
将sdk项目目录下的GeetestConfig.java拷贝到config目录中，从极验管理后台获取您的公钥（id）和私钥（key）,并配置。代码如下：
public class GeetestConfig {
// 填入自己的captcha_id和private_key
private static final String geetest_id = "481923ee3a39373a9519bd422de1bfc8";
private static final String geetest_key = "3fbbf190b58b3b63dd6474426c3587d2";
private static final boolean newfailback = true;
public static final String getGeetest_id() {
return geetest_id;
}
public static final String getGeetest_key() {
return geetest_key;
}
public static final boolean isnewfailback() {
return newfailback;
}
}
5.编写验证控制器方法，代码如下：
package com.blog.controller;
import com.alibaba.fastjson.JSONObject;
import com.dufan.config.GeetestConfig;
import com.dufan.utils.GeetestLib;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.ResponseBody;
import javax.servlet.http.HttpServletRequest;
import java.util.HashMap;
/**
* @author huxiaoguang
* @DATE 2019年01月18日
*/
@Controller
@RequestMapping("/Geetest")
public class GeetestController
{
/**
* 初始化验证码
* @param
* @return
*/
@ResponseBody
@RequestMapping(value = "initVerify", method = RequestMethod.GET, headers = "Accept=application/json")
private JSONObject init(HttpServletRequest request)
{
GeetestConfig config = new GeetestConfig();
GeetestLib gtSdk = new GeetestLib(config.getGeetest_id(), config.getGeetest_key(), config.isnewfailback());
String challenge = request.getParameter(GeetestLib.fn_geetest_challenge);
String validate = request.getParameter(GeetestLib.fn_geetest_validate);
String seccode = request.getParameter(GeetestLib.fn_geetest_seccode);
//从session中获取gt-server状态
int gt_server_status_code = (Integer) request.getSession().getAttribute(gtSdk.gtServerStatusSessionKey);
//自定义参数,可选择添加
HashMap<String, String> param = new HashMap<String, String>();
param.put("user_id", "blog"); //网站用户id
param.put("client_type", "h5");
param.put("ip_address", "xxx.xx.xx.xxx"); //传输用户请求验证时所携带的IP
int gtResult = 0;
if (gt_server_status_code == 1)
{
//gt-server正常，向gt-server进行二次验证
gtResult = gtSdk.enhencedValidateRequest(challenge, validate, seccode, param);
} else {
// gt-server非正常情况下，进行failback模式验证
gtResult = gtSdk.failbackValidateRequest(challenge, validate, seccode);
}
JSONObject json = new JSONObject();
//验证成功
if (gtResult == 1)
{
json.put("status", "success");
json.put("version", gtSdk.getVersionInfo());
}
else {
json.put("status", "fail");
json.put("version", gtSdk.getVersionInfo());
}
return json;
}
}
6.前端ajax请求验证
将sdk项目目录下的gt.js拷贝到前端框架中并引入，前端代码如下：
var validate = [];
//短信登录
$("#loginbtn-sms").click(function()
{
var phone = $("#phone").val();
var verify = $("#verify").val();
var code = $("#code").val();
if(!phone)
{
$("#msg").show().html(‘<div class="msg-error"><i class="iconfont"></i>请输入手机号</div>‘);
return false;
}else{
$("#msg").hide().html();
}
//验证手机号格式
if(!isPhoneVaild(phone))
{
$("#msg").show().html(‘<div class="msg-error"><i class="iconfont"></i>手机号码格式错误</div>‘);
return false;
}else{
$("#msg").hide().html();
}
if(!code)
{
$("#msg").show().html(‘<div class="msg-error"><i class="iconfont"></i>请输入短信验证码</div>‘);
return false;
}else{
$("#msg").hide().html();
}
//极验验证
if(validate.length==0)
{
$("#msg").show().html(‘<div class="msg-error"><i class="iconfont"></i>请点击按钮进行验证</div>‘);
return false;
}else{
$("#msg").hide().html();
}
//禁用注册按钮
$("#msg").hide().html();
$(this).attr(‘disabled‘, ‘disabled‘).text(‘登录中...‘);
$.post($("#login-form").attr(‘action‘),{phone:phone,verify:verify,code:code,validate:validate},
function(json)
{
$("#loginbtn-sms").removeAttr("disabled").text(‘登录‘);
if(json.status)
{
window.location.href = json.url;
}else{
$(".getimage").attr("src", ‘/home/index/verify.html?t=‘+Math.random());
$("#msg").show().html(‘<div class="msg-error"><i class="iconfont"></i>‘+json.msg+‘</div>‘);
}
},‘json‘)
});
//获取验证码
get_remain_time = function (btn)
{
var step = 59;
var _res = setInterval(function()
{
$(‘#‘+btn).attr("disabled", true);
$(‘#‘+btn).val(‘重新发送‘ + step);
step -= 1;
if(step <= 0)
{
$(‘#‘+btn).removeAttr("disabled");
$(‘#‘+btn).val(‘获取验证码‘);
clearInterval(_res);
}
},1000);
}
//验证手机号
isPhoneVaild = function (phone)
{
var myreg = /^[1][3,4,5,7,8][0-9]{9}$/;
if (!myreg.test(phone))
{
return false;
} else {
return true;
}
}
$(document).keyup(function(event)
{
if(event.keyCode ==13)
{
$("#loginbtn").trigger("click");
}
});
//发起验证
$.get(‘/common/Sms/verify‘,{t: new Date().getTime()},
function(data)
{
initGeetest({
gt : data.gt,
challenge : data.challenge,
new_captcha: data.new_captcha,
product : "popup",
offline : !data.success
}, handlerEmbed);
},‘json‘)
handlerEmbed = function (captchaObj)
{
//发送验证码
$("#sendcode").click(function(e)
{
var phone = $("#phone").val();
if(!phone)
{
$("#msg").show().html(‘<div class="msg-error"><i class="iconfont"></i>请输入手机号</div>‘);
return false;
}
//验证手机号格式
if(!isPhoneVaild(phone))
{
$("#msg").show().html(‘<div class="msg-error"><i class="iconfont"></i>手机号码格式错误</div>‘);
return false;
}
//极验验证码验证
validate = captchaObj.getValidate();
if (!validate)
{
$("#msg").show().html(‘<div class="msg-error"><i class="iconfont"></i>请点击按钮完成验证</div>‘);
e.preventDefault();
return false;
}
$.post(‘/common/Sms/verifySend‘, {phone:phone,validate:validate,type:5},
function(json)
{
if(json.status)
{
get_remain_time(‘sendcode‘);
}else{
$("#msg").show().html(‘<div class="msg-error"><i class="iconfont"></i>‘+json.msg+‘</div>‘);
return false;
}
},‘json‘)
})
captchaObj.appendTo("#embed-captcha");
};
到此springboot整合滑动验证就完成
