对于建站的筒子们来说；垃圾广告真是让人深恶痛绝；

为了清净；搞个难以识别的验证码吧；又被用户各种吐槽；

直到后来出现了极验这个滑动的验证码；这真是一个体验好安全高的方案；

官网：http://mon/function.php

/** * geetest检测验证码 */function geetest_chcek_verify($data){ $geetest_id=C('GEETEST_ID'); $geetest_key=C('GEETEST_KEY'); $geetest=new \Org\Xb\Geetest($geetest_id,$geetest_key); $user_id=$_SESSION['geetest']['user_id']; if ($_SESSION['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; } }}

PHP

多谢 香蕉你个banana 童鞋的提醒；补上验证的函数；

五：php 生成验证码 并 验证

/Application/Home/Controller/IndexController.class.php

/** * geetest生成验证码 */public function geetest_show_verify(){ $geetest_id=C('GEETEST_ID'); $geetest_key=C('GEETEST_KEY'); $geetest=new \Org\Xb\Geetest($geetest_id,$geetest_key); $user_id = "test"; $status = $geetest->pre_process($user_id); $_SESSION['geetest']=array( 'gtserver'=>$status, 'user_id'=>$user_id ); echo $geetest->get_response_str();}/** * geetest submit 提交验证 */public function geetest_submit_check(){ $data=I('post.'); if (geetest_chcek_verify($data)) { echo '验证成功'; }else{ echo '验证失败'; }}/** * geetest ajax 验证 */public function geetest_ajax_check(){ $data=I('post.'); echo intval(geetest_chcek_verify($data));}
