给一个央企做官网，登录模块用的thinkphp验证码类。但是2019-6-10到12号，国家要求央企检验官网漏洞，防止黑客攻击，正直贸易战激烈升级时期，所以各事业单位很重视官网安全性，于是乎集团总部就委托了宁波一个专业检测公司用专业工具检测出，后台验证码能用打码工具暴力破解，发函要求整改。so，就有了下面的极速验证图形
一：注册获取key
注册；创建应用；获取key；
二：导入sdk
/ThinkPHP/Library/Org/Xb/GeetestLip.class.php（此处GeetestLip.class.php是我重新命名的geetest类文件，原名为class.geetestlib.php）
此处牵扯到thinkphp引入第三方类，我把第三方类放到Org/Util/Xb下面了，同时对该类文件加入命名空间如下，否则实例化类时找不到文件
三：生成验证样式
admin/view/public/cdtsh_log_smfyws.php
<!doctype html>
<html>
<head>
<meta charset="GBK" />
<title>网站管理系统后台</title>
<script language="javascript" type="text/javascript" src="__JS__/jquery.js"></script>
<link rel="stylesheet" href="__CSS__/jquery.validator.css">
<script type="text/javascript" src="__JS__/jquery.validator.js"></script>
<script type="text/javascript" src="__JS__/zh_CN.js"></script>
<link href="__CSS__/admin_login.css?v20130227" rel="stylesheet" />
<script>
$(document).ready(function(){
var verifyimg = $(".verifyimg").attr("src");
$(".reloadverify").click(function(){
if( verifyimg.indexOf('?')>0){
$(".verifyimg").attr("src", verifyimg+'&random='+Math.random());
}else{
$(".verifyimg").attr("src", verifyimg.replace(/\?.*$/,'')+'?'+Math.random());
}
});
}); </script> </head> <body> <div class="wrap"> <h1><a href="javascript:;" style="height: 116px; width: 250px;">后台管理中心</a></h1> <form method="post" action="{:U('Admin/Public/cdtsh_log_smfyws')}"> <div class="login"> <ul> <li> <input class="input" id="username" name="username"type="text" title="用户名" data-rule="required;username" placeholder="用户名" /> <span class="msg-box n-right" style="position:absolute; left: 248px; top: 12px; " for="username"></span> </li> <li> <input class="input" name="password" type="password" title="密码" data-rule="required;password" placeholder="密码"/> <span class="msg-box n-right" style="position:absolute;left: 248px; top: 12px;" for="password"></span> </li> <li> <input class="input" id="verify" name="verify" type="text" style="width:130px;" title="密码" data-ok=" " placeholder="验证码" data-tip="输入验证码！" title="验证码" data-rule="required;text;remote[{:U('Admin/Public/check_verify')}]" /> <div class="yanzhengma_box" id="verifyshow"> <img class="verifyimg reloadverify" style=" cursor: pointer;" align="right" src="{:U('public/verify')}" title="点击刷新"> </div> <span class="msg-box n-right" style="position:absolute;left: 248px; top: 12px;" for="verify"></span> </li> </ul>
<ul> <!--<input type="button" value="异步验证登录" onclick="check_verify()">-->
<!--<input type="submit" value="post提交登录">-->
<div id="captcha"></div> </ul> <button type="submit" class="btn" id="subbtn">登录</button> </div> </form> </div> <script src="http://static.geetest.com/static/tools/gt.js"></script>
<script>
var handler = function (captchaObj) {
// 将验证码加到id为captcha的元素里
captchaObj.appendTo("#captcha");
};
// 获取验证码
$.get("{:U('Admin/Public/verifys')}", function(data) {
// 使用initGeetest接口
// 参数1：配置参数，与创建Geetest实例时接受的参数一致
// 参数2：回调，回调的第一个参数验证码对象，之后可以使用它做appendTo之类的事件
initGeetest({
gt: data.gt,
challenge: data.challenge,
product: "float", // 产品形式
offline: !data.success,
new_captcha:'true',
width:'260px',
}, handler);
},'json'); </script> </body> </html>
四：验证函数
/Application/Common/Common/function.php
/**
* geetest检测验证码
*/
function geetest_chcek_verify($data){
$geetest_id = "7149e2021d7938157e";
$geetest_key = "62b92039e1e9cf9455";
$geetest=new \Org\Util\Xb\GeetestLib($geetest_id,$geetest_key);
$user_id=$_SESSION['geetest']['user_id'];
$ip_address=$_SESSION['geetest']['ip_address'];
$dataa = array(
"user_id" => $user_id, # 网站用户id
"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
"ip_address" => $ip_address, # 请在此处传输用户请求验证时所携带的IP
);
if ($_SESSION['geetest']['gtserver']==1){
$result=$geetest->success_validate($data['geetest_challenge'], $data['geetest_validate'], $data['geetest_seccode'], $dataa);
//return $result;
if ($result) {
//return 11;
return true;
} else{
//return 22;
return false;
}
}else{
if ($geetest->fail_validate($data['geetest_challenge'],$data['geetest_validate'],$data['geetest_seccode'])) {
//return 33;
return true;
}else{
//return 44;
return false;
}
}
} //获取id地址
function GetIP() {
if (!empty($_SERVER["HTTP_CLIENT_IP"])) {
$cip = $_SERVER["HTTP_CLIENT_IP"];
} elseif (!empty($_SERVER["HTTP_X_FORWARDED_FOR"])) {
$cip = $_SERVER["HTTP_X_FORWARDED_FOR"];
} elseif (!empty($_SERVER["REMOTE_ADDR"])) {
$cip = $_SERVER["REMOTE_ADDR"];
} else {
$cip = "无法获取！";
}
return $cip;
}
五：php 生成验证码 并 验证
//极速验证
public function verifys(){
//require_once dirname(dirname(dirname(__FILE__))) . '/lib/class.geetestlib.php';
//require_once dirname(dirname(__FILE__)) . '/config/config.php'; // $GtSdk = new GeetestLib(CAPTCHA_ID, PRIVATE_KEY);
$geetest_id = "7149e2021d7938157e9";
$geetest_key = "62b92039e1e9cf";
$geetest=new \Org\Util\Xb\GeetestLib($geetest_id,$geetest_key);
//dump($geetest);die;
$user_id = "test";
$data = array(
"user_id" => $user_id, # 网站用户id
"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
"ip_address" => GetIP(), # 请在此处传输用户请求验证时所携带的IP
);
$status = $geetest->pre_process($data,1);
//dump($status);
$_SESSION['geetest']=array(
'gtserver'=>$status,
'user_id'=>$user_id,
'ip_address'=>GetIP(),
);
echo $geetest->get_response_str();
} public function cdtsh_log_smfyws() {
if ($_SESSION['userid']) {
$this->redirect('Admin/Index/Index');
} else {
if (IS_POST) {
$username = $_POST['username'];
$password = $_POST['password'];
//$geetest_challenge = $_POST['geetest_challenge'];
//$geetest_validate = $_POST['geetest_validate'];
//$geetest_seccode = $_POST['geetest_seccode'];
$data=I('post.');
if($data['geetest_challenge']=="" || $data['geetest_validate']=="" ||$data['geetest_seccode']=="" ){
$this->error('请进行图形验证');
}else{
//dump(geetest_chcek_verify($data));
if (geetest_chcek_verify($data)){
//echo '验证成功';
if ($this->loginAdmin($username, $password)) {
$data = M("User")->where("username='".$username."' and password='".md5($password)."'")->find();
if ($data["status"] != 1) {
//判断是否禁用
$this->recordLoginAdmin($_POST['username'], $_POST['password'], 0, "账号禁用"); //记录登录日志
$this->error('该帐号禁用');
} else {
$save["lastlogin_time"] = time();
$save["lastlogin_ip"] = get_client_ip();
$save["login_num"] = $data["login_num"] + 1;
$status = M("user")->where(array("id" => $data['id']))->save($save);
$_SESSION['userid'] = $data['id'];
$_SESSION['user'] = $data['username'];
$_SESSION['rid'] = $data['a_Id'];
$this->recordLoginAdmin($_POST['username'], $_POST['password'], 1); //记录登录日志 $this->redirect('Admin/Index/Index');
//$this->success('登录成功',U('Admin/Index/Index'));
}
} else {
$this->recordLoginAdmin($_POST['username'], $_POST['password'], 0, "账号密码错误"); //记录登录日志
$this->error('登录失败');
}
}else{
//echo '图形验证失败';
$this->error('图形验证失败');
}
}
} else {
$this->display();
}
}
}
到这里就结束了
