Its a register page, with recaptcha from google. 它是一个注册页面，来自Google的Recaptcha。 I have added the secret key from google which I got for my domain https://molugu.com . 我已经添加了我从我的域https://molugu.com获得的google的密钥。 But when I am loading my registeration page, its showing the following error: 但是，当我加载我的注册页面时，它显示以下错误：

ERROR for site owner: Invalid site key 网站所有者错误：网站密钥无效

The code for recaptcha is as follows: recaptcha的代码如下：

 <?php class ReCaptchaResponse { public $success; public $errorCodes; } class ReCaptcha { private static $_signupUrl = "https://www.google.com/recaptcha/admin"; private static $_siteVerifyUrl = "https://www.google.com/recaptcha/api/siteverify?"; private $_secret; private static $_version = "php_1.0"; /** * Constructor. * * @param string $secret shared secret between site and ReCAPTCHA server. */ function ReCaptcha($secret) { if ($secret == null || $secret == "") { die("To use reCAPTCHA you must get an API key from <a href='" . self::$_signupUrl . "'>" . self::$_signupUrl . "</a>"); } $this->_secret=$secret; } /** * Encodes the given data into a query string format. * * @param array $data array of string elements to be encoded. * * @return string - encoded request. */ private function _encodeQS($data) { $req = ""; foreach ($data as $key => $value) { $req .= $key . '=' . urlencode(stripslashes($value)) . '&'; } // Cut the last '&' $req=substr($req, 0, strlen($req)-1); return $req; } /** * Submits an HTTP GET to a reCAPTCHA server. * * @param string $path url path to recaptcha server. * @param array $data array of parameters to be sent. * * @return array response */ private function _submitHTTPGet($path, $data) { $req = $this->_encodeQS($data); $response = file_get_contents($path . $req); return $response; } /** * Calls the reCAPTCHA siteverify API to verify whether the user passes * CAPTCHA test. * * @param string $remoteIp IP address of end user. * @param string $response response string from recaptcha verification. * * @return ReCaptchaResponse */ public function verifyResponse($remoteIp, $response) { // Discard empty solution submissions if ($response == null || strlen($response) == 0) { $recaptchaResponse = new ReCaptchaResponse(); $recaptchaResponse->success = false; $recaptchaResponse->errorCodes = 'missing-input'; return $recaptchaResponse; } $getResponse = $this->_submitHttpGet( self::$_siteVerifyUrl, array ( 'secret' => $this->_secret, 'remoteip' => $remoteIp, 'v' => self::$_version, 'response' => $response ) ); $answers = json_decode($getResponse, true); $recaptchaResponse = new ReCaptchaResponse(); if (trim($answers ['success']) == true) { $recaptchaResponse->success = true; } else { $recaptchaResponse->success = false; $recaptchaResponse->errorCodes = $answers [error-codes]; } return $recaptchaResponse; } } ?>

Can anyone please tell me what could be the problem in recaptcha? 谁能告诉我重新验证可能是什么问题？

Answer 1

Process for use reCAPTCHA 使用过程reCAPTCHA

First create Google reCAPTCHA account 首先创建Google reCAPTCHA帐户

After that copy credentials and put them into code after that your reCAPTCHA will work successfully. 之后，复制凭据并将其放入代码中，之后您的reCAPTCHA将成功运行。

You can use Using reCAPTCHA with PHP tutorial to successfully configure captcha using PHP 您可以使用“ 将reCAPTCHA与PHP结合使用”教程来使用PHP成功配置验证码

Answer 3

You have the http version of website http://molugu.com/demo/vendor/register.php , and you have registered reCaptcha with https version: https://molugu.com , you need to specify both versions there. 你有网站的HTTP版本http://molugu.com/demo/vendor/register.php ，并且您已经注册验证码以https版本： https://molugu.com ，你需要指定有两个版本。

Also you need to use "The reCAPTCHA PHP Library" provided by Google reCaptcha. 另外，您还需要使用Google reCaptcha提供的“ reCAPTCHA PHP库”。 Find out more here: Using reCAPTCHA with PHP 在此处了解更多信息：将reCAPTCHA与PHP结合使用
