眼镜网站怎么做竞价/创建自己的网站

专业的事给专业的做，验证码第三方化还是比较爽的

官网：http://www.geetest.com/

一：注册获取key
    注册->创建应用->获取id和key

二：配置

    /conf/config.php（配置文件提出到根目录下conf）

三：导入sdk

    /extend/geetest/Geetest

四：生成验证样式

<div class="box"><h4><a target="_blank" href="#">thinkphp5整合geetest极验滑动验证码</a></h4><form id="geetest" action="{:url('index/User/login')}" method="post">账号：<input type="text" name="username" value="admin">密码：<input type="text" name="password" value="111111"><input type="button" value="异步验证登录" onclick="verify()"><input type="submit" value="post提交登录"><div id="captcha"></div></form>
</div>
<script src="/Public/statics/js/jquery-1.10.2.min.js"></script>
<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("{:url('index/User/captcha')}", 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}, handler);},'json');// 检测验证码function verify(){// 组合验证需要用的数据var data = {geetest_challenge: $('.geetest_challenge').val(),geetest_validate: $('.geetest_validate').val(),geetest_seccode: $('.geetest_seccode').val()}// 验证是否通过$.post("{:url('index/User/gtAsyncVerify')}", data, function(response) {if (response == 1) {alert('验证成功');}else{alert('验证失败');}});}
</script>

五：验证函数

    /conf/extra/function.php

<?php
use geetest\Geetest;
use think\Session;
/*** geetest检测验证码* @param $data* @return bool*/
function gtVerify($data){$geetest_id = config('geetest.id');$geetest_key = config('geetest.key');$geetest = new Geetest($geetest_id, $geetest_key);$user_id = Session::get('geetest.user_id');if (Session::get('geetest.gtserver') == 1) {$result = $geetest->success_validate($data['geetest_challenge'], $data['geetest_validate'], $data['geetest_seccode'], $user_id);if ($result) {return true;} else{return false;}}else{if ($geetest->fail_validate($data['geetest_challenge'], $data['geetest_validate'], $data['geetest_seccode'])) {return true;}else{return false;}}
}

六：php 生成验证码 并 验证

    /*** geetest生成验证码*/public function captcha(){$geetest_id = config('geetest.id');$geetest_key = config('geetest.key');$geetest = new Geetest($geetest_id, $geetest_key);$user_id = [uniqid() . rand(1000, 9999)];$status = $geetest->pre_process($user_id);Session::set('geetest', ['gtserver' => $status, 'user_id' => $user_id]);echo $geetest->get_response_str();}/*** 登录* @return mixed*/public function login(){if(request()->isPost()){$data = input('post.');if(!gtVerify($data)){$this->error('验证码错误');}$res = self::$event->login($data);if($res['status'] == 1){return $this->success($res['msg']);}else{return $this->error($res['msg']);}}else{return $this->fetch();}}/*** geetest异步验证*/public function verify(){$data = input('post.');echo intval(gtVerify($data));}
