Geetest极验验证码的使用

后端部署
1.首先从Github: gt3-python-sdk下载.zip文件，用于后台搭建
gt3-java-sdk-master\src\sdk\GeetestLib.java 这个文件相当java中的实体类
gt3-java-sdk-master\src\demo\demo1\GeetestConfig.java ，是geetest的配置文件，用来放我们在极验后台注册应用得到的captcha_id和private_key。
VerifyLoginServlet.java（验证）和 StartCaptchaServlet.java（初始化），这两个文件就是两个servlet，我直接放到了我写的一个Controller里面；

import com.jhly.common.config.GeetestConfig;
import com.jhly.common.domain.GeetestLib;
import org.activiti.engine.impl.util.json.JSONException;
import org.activiti.engine.impl.util.json.JSONObject;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.PostMapping;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;

import javax.servlet.ServletException;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import java.io.IOException;
import java.io.PrintWriter;
import java.util.HashMap;

@Controller
@RequestMapping("/gt")
public class GeetestController {

/*** 初始化极验** @param request* @param geetestDto* @param random 防止缓存* @return*/
@GetMapping("/register")
@ResponseBody
protected void register(HttpServletRequest request,HttpServletResponse response) throws ServletException, IOException {GeetestLib gtSdk = new GeetestLib(GeetestConfig.getGeetest_id(), GeetestConfig.getGeetest_key(),GeetestConfig.isnewfailback());String resStr = "{}";String userid = "test";//自定义参数,可选择添加HashMap<String, String> param = new HashMap<String, String>();param.put("user_id", userid); //网站用户idparam.put("client_type", "web"); //web:电脑上的浏览器；h5:手机上的浏览器，包括移动应用内完全内置的web_view；native：通过原生SDK植入APP应用的方式param.put("ip_address", "127.0.0.1"); //传输用户请求验证时所携带的IP//进行验证预处理int gtServerStatus = gtSdk.preProcess(param);//将服务器状态设置到session中request.getSession().setAttribute(gtSdk.gtServerStatusSessionKey, gtServerStatus);//将userid设置到session中request.getSession().setAttribute("userid", userid);resStr = gtSdk.getResponseStr();PrintWriter out = response.getWriter();out.println(resStr);}
/*** 使用post方式，返回验证结果, request表单中必须包含challenge, validate, seccode*/
@PostMapping("/validate")
@ResponseBodyprotected void validate(HttpServletRequest request,HttpServletResponse response) throws ServletException, IOException {GeetestLib gtSdk = new GeetestLib(GeetestConfig.getGeetest_id(), GeetestConfig.getGeetest_key(),GeetestConfig.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);//从session中获取useridString userid = (String)request.getSession().getAttribute("userid");//自定义参数,可选择添加HashMap<String, String> param = new HashMap<String, String>();param.put("user_id", userid); //网站用户idparam.put("client_type", "web"); //web:电脑上的浏览器；h5:手机上的浏览器，包括移动应用内完全内置的web_view；native：通过原生SDK植入APP应用的方式param.put("ip_address", "127.0.0.1"); //传输用户请求验证时所携带的IPint 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);System.out.println(gtResult);} else {// gt-server非正常情况下，进行failback模式验证System.out.println("failback:use your own server captcha validate");gtResult = gtSdk.failbackValidateRequest(challenge, validate, seccode);System.out.println(gtResult);}if (gtResult == 1) {// 验证成功PrintWriter out = response.getWriter();JSONObject data = new JSONObject();try {data.put("status", "success");data.put("version", gtSdk.getVersionInfo());} catch (JSONException e) {e.printStackTrace();}out.println(data.toString());}else {// 验证失败JSONObject data = new JSONObject();try {data.put("status", "fail");data.put("version", gtSdk.getVersionInfo());} catch (JSONException e) {e.printStackTrace();}PrintWriter out = response.getWriter();out.println(data.toString());}}

注意：config文件里需要添加上注册给的id和key，这是每个人独有的

前端vue里
1.导入gt.js文件

2.在main.js里添加

3.，这就可以了
