ThinkPHP5实现极验滑动验证码geetest功能
现在很多网站，比如淘宝，京东等都改用使用极验拖动验证码实现登录，这种方式比传统的验证码方式有更好的体验，减少用户输入的错误，也同样能起到防盗刷的功能。现在很多极验都是第三方的，也很多都是收费的。
这里主要介绍thinkphp整合系列之极验滑动验证码geetest，官网：http://www.geetest.com
具体如下：
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><p 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')}"> <p 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')}]" /> <p class="yanzhengma_box" id="verifyshow"> <img class="verifyimg reloadverify" style=" cursor: pointer;" align="right" src="{:U('public/verify')}" title="点击刷新"> </p> <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">--> <p id="captcha"></p> </ul> <button type="submit" class="btn" id="subbtn">登录</button> </p> </form></p><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(); } }}效果图如下：
