old: // set peer verification if (!this->verifyPeer) { curl_easy_setopt( getCurlHandle(), CURLOPT_SSL_VERIFYPEER, this->verifyPeer); } new // set peer verification if (!this->verifyPeer) { curl_easy_setopt( getCurlHandle(), CURLOPT_SSL_VERIFYHOST, this->verifyPeer); curl_easy_setopt( getCurlHandle(), CURLOPT_SSL_VERIFYPEER, this->verifyPeer); }
