Добрый вечер. Дано: сертификат, выданный доверенным источником (не самоподписанный). Задача: получить информацию с удалённого сервера с помощью cURL, предотвратив при этом его возможную фальсификацию. Моё видение реализации: | Код |
/* curl part */
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL,"https://remoteserver.ru");
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, true);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 2);
curl_setopt($ch, CURLOPT_SSLVERSION,3);
curl_setopt($ch, CURLOPT_CERTINFO,true);
curl_setopt($ch, CURLOPT_CAINFO, dirname(__FILE__)."/www.remoteserver.ru.crt");
$result = curl_exec($ch);
if (curl_errno($ch) != 0) {
echo "cURL connection problem, ".curl_errno($ch).": ".curl_error($ch);
}
/* curl part */
print_r( curl_getinfo($ch) );

В итоге выполнения получается: | Код |

В выводе, есть две секции [certinfo][0] и [certinfo][1]. В чём их разница и к чему нужно привязать проверку? Заранее спасибо за ответы. Это сообщение отредактировал(а) night00 - 27.10.2012, 22:45 |
