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
网站管理系统后台
后台管理中心
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：
登录页面
点击验证后
