最近項目短信發(fā)送被人刷了，加了驗證碼，感覺不好用，改為滑塊驗證，這里記錄下。
1 下載 sdk ，解壓放到項目里面。

GeetestConfig 代碼：

注意要把這里的id 和key 替換成自己注冊的。這里用的是官網(wǎng)提供的文檔

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 加載滑塊代碼：

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;
/**
 * 獲取滑塊 驗證 
 * @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 = "{}";
// 自定義userid
String userid = "test";
//自定義參數(shù),可選擇添加
HashMap<String, String> param = new HashMap<String, String>(); 
param.put("user_id", userid); //網(wǎng)站用戶id
//param.put("client_type", "web"); //web:電腦上的瀏覽器；h5:手機上的瀏覽器，包括移動應(yīng)用內(nèi)完全內(nèi)置的web_view；native：通過原生SDK植入APP應(yīng)用的方式
//param.put("ip_address", "127.0.0.1"); //傳輸用戶請求驗證時所攜帶的IP
// 進行驗證預(yù)處理
int gtServerStatus = gtSdk.preProcess(param);
// 將服務(wù)器狀態(tài)設(shè)置到session中
request.getSession().setAttribute(gtSdk.gtServerStatusSessionKey, gtServerStatus);
// 將userid設(shè)置到session中
request.getSession().setAttribute("geetuserid", userid);
resStr = gtSdk.getResponseStr();
PrintWriter out = response.getWriter();
out.println(resStr);
}
}

VerifyLoginController 驗證代碼：

import java.util.HashMap;
import java.util.Map;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;
import com.ganjiangps.wangdaibus.config.geetest.sdk.java.GeetestLib;
/**
 * 驗證測試 Controller
 * @author admin
 *
 */
@Controller
public class VerifyLoginController {
@ResponseBody
@RequestMapping("/verifyLogin")
public Map<String,String> verifyLogin(HttpServletRequest request,
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);
String seccode = request.getParameter(GeetestLib.fn_geetest_seccode);
//從session中獲取gt-server狀態(tài)
int gt_server_status_code = (Integer) request.getSession().getAttribute(gtSdk.gtServerStatusSessionKey);
//從session中獲取userid
String userid = (String)request.getSession().getAttribute("geetuserid");
//自定義參數(shù),可選擇添加
HashMap<String, String> param = new HashMap<String, String>(); 
param.put("user_id", userid); //網(wǎng)站用戶id
//param.put("client_type", "web"); //web:電腦上的瀏覽器；h5:手機上的瀏覽器，包括移動應(yīng)用內(nèi)完全內(nèi)置的web_view；native：通過原生SDK植入APP應(yīng)用的方式
//param.put("ip_address", "127.0.0.1"); //傳輸用戶請求驗證時所攜帶的IP
int gtResult = 0;
if (gt_server_status_code == 1) {
//gt-server正常，向gt-server進行二次驗證
gtResult = gtSdk.enhencedValidateRequest(challenge, validate, seccode, param);
System.out.println(gtResult);
} else {
// gt-server非正常情況下，進行failback模式驗證
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) {
// 驗證成功
data.put("status", "success");
data.put("version", gtSdk.getVersionInfo());
 } else {
// 驗證失敗
data.put("status", "fail");
data.put("version", gtSdk.getVersionInfo());
 }
return data;
}
}
