最近项目短信发送被人刷了，加了验证码，感觉不好用，改为滑块验证，这里记录下。
1 下载 sdk ，解压放到项目里面。

GeetestConfig 代码：
注意要把这里的id 和key 替换成自己注册的。这里用的是官网提供的文档
import javax.swing.text.StyledEditorKit.BoldAction;
/**
* GeetestWeb配置文件
*
*
*/
public class GeetestConfig {
// 填入自己的captcha_id和private_key
private static final String geetest_id = "002bc30ff1eef93e912f45814945e752";
private static final String geetest_key = "4193a0e3247b82a26f563d595c447b1a";
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;
}
}
StartCaptchaController 加载滑块代码：
import java.io.IOException;
import java.io.PrintWriter;
import java.util.HashMap;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import com.ganjiangps.wangdaibus.config.geetest.sdk.java.GeetestLib;
/**
* 获取滑块 验证
* @author cjm
*
*/
@Controller
public class StartCaptchaController {
@RequestMapping("/startCaptcha")
public void StartCaptcha(HttpServletRequest request,
HttpServletResponse response) throws IOException{
GeetestLib gtSdk = new GeetestLib(GeetestConfig.getGeetest_id(), GeetestConfig.getGeetest_key(),true);
String resStr = "{}";
// 自定义userid
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id
//param.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("geetuserid", userid);
resStr = gtSdk.getResponseStr();
PrintWriter out = response.getWriter();
out.println(resStr);
}
}
VerifyLoginController 验证代码：
import java.util.HashMap;
import java.util.Map;
import javax.servlet.ServletException;

import org.springframework.stereotype.Controller;

@Controller
public class VerifyLoginController {
@ResponseBody

HttpServletResponse response){
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);

//从session中获取gt-server状态
int gt_server_status_code = (Integer) request.getSession().getAttribute(gtSdk.gtServerStatusSessionKey);

String userid = (String)request.getSession().getAttribute("geetuserid");
//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id
//param.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
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);
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);
}
Map<String,String> data = new HashMap<>();
if (gtResult == 1) {
// 验证成功
data.put("status", "success");
data.put("version", gtSdk.getVersionInfo());
} else {
// 验证失败
data.put("status", "fail");
data.put("version", gtSdk.getVersionInfo());
}
return data;
}
}
