Recaptcha não está funcionando em https

Eu tenho um site no codeigniter, e esse site funciona perfeitamente no http .

Meu cliente mudou o site para https .

Então, agora, quando o registro do usuário não está funcionando, porque há um recaptcha usado nela.

Agora ele exibe Could not open socket erro de Could not open socket .

Esta é a chamada recaptcha no meu controlador:

 $privatekey = "my-key"; $resp = recaptcha_check_answer ($privatekey, $_SERVER["REMOTE_ADDR"], $_POST["recaptcha_challenge_field"], $_POST["recaptcha_response_field"]); if (!$resp->is_valid) { // What happens when the CAPTCHA was entered incorrectly die ("The reCAPTCHA wasn't entered correctly"); }else{ $data=$this->authmodel->addAccount(); $this->session->set_flashdata('abc', 'User added successfully'); echo "1"; } 

E este é o código recaptchalib.php:

  $value ) $req .= $key . '=' . urlencode( stripslashes($value) ) . '&'; // Cut the last '&' $req=substr($req,0,strlen($req)-1); return $req; } /** * Submits an HTTP POST to a reCAPTCHA server * @param string $host * @param string $path * @param array $data * @param int port * @return array response */ function _recaptcha_http_post($host, $path, $data, $port = 80) { $req = _recaptcha_qsencode ($data); $http_request = "POST $path HTTP/1.0\r\n"; $http_request .= "Host: $host\r\n"; $http_request .= "Content-Type: application/x-www-form-urlencoded;\r\n"; $http_request .= "Content-Length: " . strlen($req) .

Então, como posso resolver esse problema?

Eu recebi o mesmo erro e tentei algumas sugestões, mas nada realmente funcionou.

Então registrei o tráfego da rede e analisei-o. O que mostra é que a conexão intermediária dos servidores mudou de ipv4 para ipv6 e lembrei de ler em algum lugar que o recaptcha tem um problema no trabalho no ipv6.

Então, mudei @fsockopen($host, [...] para @fsockopen(gethostbyname($host), [...] e recaptcha funcionou novamente.

Para uso de SSL (https):

 echo recaptcha_get_html($publickey,true); 

ao invés de:

 echo recaptcha_get_html($publickey); 

Isso ocorre porque recaptcha_get_html () em recaptchalib.php (que obtém a imagem de texto distorcida) padrão para http, a menos que você diga o contrário.

edite recaptchalib.php assim:

encontre esta linha – function recaptcha_get_html ($ pubkey, $ error = null, $ use_ssl = false)

altere-o para – function recaptcha_get_html ($ pubkey, $ error = null, $ use_ssl = true)

argumento $ use_ssl é alterado de falso para verdadeiro … o resto será cuidado pelo script ..

Eu recebi o mesmo erro e tentei todas as sugestões, mas nada funciona para mim.

então eu analisei o problema e então eu consegui problema de certificado SSL

Este certificado é válido somente para os seguintes nomes: http://www.google.com (Código de erro: ssl_error_bad_cert_domain)

então eu mudei

 echo recaptcha_get_html($publickey,,true); @fsockopen($host, [...] to @fsockopen(gethostbyname($host), [...] 

junto com

define (“RECAPTCHA_API_SECURE_SERVER”, ” https://api-secure.recaptcha.net “);

para

define (“RECAPTCHA_API_SECURE_SERVER”, ” https://www.google.com/recaptcha/api “);

em recaptchalib.php e Recaptcha trabalhou novamente.

Você precisa dizer a function “recaptcha_get_html ()” que você deseja usar https. Substitua recaptcha_get_html ($ publickey) por

 echo recaptcha_get_html($publickey,null,1); 

Você precisa alterar todos os http: // urls para https: // no arquivo “recaptchalib.php”, depois disso isso funcionará.
