ThinkPHP5實現極驗滑動驗證碼geetest功能
現在很多網站，比如淘寶，京東等都改用使用極驗拖動驗證碼實現登錄，這種方式比傳統的驗證碼方式有更好的體驗，減少用戶輸入的錯誤，也同樣能起到防盜刷的功能。現在很多極驗都是第三方的，也很多都是收費的。
這里主要介紹thinkphp整合系列之極驗滑動驗證碼geetest，官網：http://www.geetest.com
具體如下：
一：注冊獲取key
注冊；創建應用；獲取key；
二：導入sdk
/ThinkPHP/Library/Org/Xb/GeetestLip.class.php（此處GeetestLip.class.php是我重新命名的geetest類文件，原名為class.geetestlib.php）
此處牽扯到thinkphp引入第三方類，我把第三方類放到Org/Util/Xb下面了，同時對該類文件加入命名空間如下，否則實例化類時找不到文件
三：生成驗證樣式
admin/view/public/cdtsh_log_smfyws.php
<!doctype html>

<head>
<meta charset="GBK" />
<title>網站管理系統后臺</title>

<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">

<form method="post" action="{:U('Admin/Public/cdtsh_log_smfyws')}">

</ul>
<ul>
<!--<input type="button" value="異步驗證登錄" onclick="check_verify()">-->
<!--<input type="submit" value="post提交登錄">-->

</p>
<script src="http://static.geetest.com/static/tools/gt.js"></script>
<script>
var handler = function (captchaObj) {
// 將驗證碼加到id為captcha的元素里
captchaObj.appendTo("#captcha");
};
// 獲取驗證碼
$.get("{:U('Admin/Public/verifys')}", function(data) {
// 使用initGeetest接口
// 參數1：配置參數，與創建Geetest實例時接受的參數一致
// 參數2：回調，回調的第一個參數驗證碼對象，之后可以使用它做appendTo之類的事件
initGeetest({
gt: data.gt,
challenge: data.challenge,
product: "float", // 產品形式
offline: !data.success,
new_captcha:'true',
width:'260px',
}, handler);
},'json');
</script>
</body>
</html>四：驗證函數
/Application/Common/Common/function.php
/**
* geetest檢測驗證碼
*/
function geetest_chcek_verify($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, # 網站用戶id
"client_type" => "web", #web:電腦上的瀏覽器；h5:手機上的瀏覽器，包括移動應用內完全內置的web_view；native：通過原生SDK植入APP應用的方式
"ip_address" => $ip_address, # 請在此處傳輸用戶請求驗證時所攜帶的IP
);
if ($_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;
}
}
}
//獲取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 = "無法獲取！";
}
return $cip;
}五：php生成驗證碼并驗證
//極速驗證
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, # 網站用戶id
"client_type" => "web", #web:電腦上的瀏覽器；h5:手機上的瀏覽器，包括移動應用內完全內置的web_view；native：通過原生SDK植入APP應用的方式
"ip_address" => GetIP(), # 請在此處傳輸用戶請求驗證時所攜帶的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']=="" ){
$this->error('請進行圖形驗證');
}else{
//dump(geetest_chcek_verify($data));
if (geetest_chcek_verify($data)){
//echo '驗證成功';
if ($this->loginAdmin($username, $password)) {
$data = M("User")->where("username='".$username."' and password='".md5($password)."'")->find();
if ($data["status"] != 1) {
//判斷是否禁用
$this->recordLoginAdmin($_POST['username'], $_POST['password'], 0, "賬號禁用"); //記錄登錄日志
$this->error('該帳號禁用');
} 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); //記錄登錄日志
$this->redirect('Admin/Index/Index');
//$this->success('登錄成功',U('Admin/Index/Index'));
}
} else {
$this->recordLoginAdmin($_POST['username'], $_POST['password'], 0, "賬號密碼錯誤"); //記錄登錄日志
$this->error('登錄失敗');
}
}else{
//echo '圖形驗證失敗';
$this->error('圖形驗證失敗');
}
}
} else {
$this->display();
}
}
}效果圖如下：
