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
官网：
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
