提交表单时codeigniter php中的google recaptcha错误

Question

我在 codeigniter 中创建了一个表单并提供了一个 google 验证码 v2，我创建了站点密钥和密钥，将其添加到配置文件中，还添加了 js 和 recaptcha div，包括我的站点密钥。以下是我在控制器中的验证码功能：public function validate_captcha() {          $recaptcha = trim($this->input->post('g-recaptcha-response'));          $userIp= $this->input->ip_address();          $secret='xxxxxxxxxxxx'; (i have given my scret key here)          $secretdata = array(              'secret' => "$secret",              'response' => "$recaptcha",              'remoteip' =>"$userIp"          );          $verify = curl_init();          curl_setopt($verify, CURLOPT_URL, "https://www.google.com/recaptcha/api/siteverify");          curl_setopt($verify, CURLOPT_POST, true);          curl_setopt($verify, CURLOPT_POSTFIELDS, http_build_query($secretdata));          curl_setopt($verify, CURLOPT_SSL_VERIFYPEER, false);          curl_setopt($verify, CURLOPT_RETURNTRANSFER, true);          $response = curl_exec($verify);          $status= json_decode($response, true);          if(empty($status['success'])){              return FALSE;          }else{              return TRUE;          }      }以下是我在同一控制器中的注册表格功能：public function ajaxRegAction() { $this->load->library('session'); header('Access-Control-Allow-Origin: *'); header('Access-Control-Allow-Methods: GET, POST, PATCH, PUT, DELETE, OPTIONS'); header('Access-Control-Allow-Headers: Origin, Content-Type, X-Auth-Token'); $this->load->library('form_validation'); $utype='W';    $dhamu = $this->validate_captcha(); $createddate  = date('Y-m-d h:i:s'); $createdby = '0'; $mobile = $this->input->post('phone'); $form_data = array( 'type' => $utype, 'unique_id' => $this->mainModel->generateIndividualID(), 'phone_num' => $mobile, 'email' => $this->input->post('email'), 'first_name' => $this->input->post('firstname'), 'last_name' => $this->input->post('lastname'), 'created_by' => $createdby, 'created_date' => $createddate, );即使我检查了 google recaptcha 框并按注册，表单显示“Captcha 错误”，值也没有被添加到数据库中。谁能告诉我这里可能出了什么问题，在此先感谢

Answer 1

第 1 步：确保您已localhost在 Google Captcha V2 仪表板中添加您的域。

第2步：

我正在修改你的功能，你可以像这样使用它：

public function validate_captcha() 

{

    if(isset($_POST['g-recaptcha-response']))

    {

        $captcha=$_POST['g-recaptcha-response'];

    }

    $secretKey = "Put your secret key here";

    $ip = $_SERVER['REMOTE_ADDR'];

    // post request to server

    $url = 'https://www.google.com/recaptcha/api/siteverify?secret=' . urlencode($secretKey) .  '&response=' . urlencode($captcha);

    $response = file_get_contents($url);

    $responseKeys = json_decode($response,true);

    // should return JSON with success as true

    if($responseKeys["success"]) {

        return TRUE;

    } else {

        return FALSE;

    }

}

而不是卷曲

如果这有效，请告诉我
