Captcha entry via curl. How to send a captcha?

Question

PHP

Hello! I am engaged in layout in a seo-company, I am a little familiar with php, they asked me to auto-register Yandex accounts for parsing results through the Key Collector. I drew 2 functions, one takes data from https://passport.yandex.ru/registration, including captcha. Another one processes this captcha through api ruCaptcha and returns the answer. But it turns out that when I try to enter data on the Yandex page via curl, the captcha has already changed.

function regYandexAcc($login, $pass)
{
    $url = 'https://passport.yandex.ru/registration';
    $cookiefile = 'cookie.txt';
    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL, $url ); // отправляем на
    curl_setopt($ch, CURLOPT_USERAGENT, "Mozilla/5.0 (Windows NT 6.1; WOW64; rv:23.0) Gecko/20100101 Firefox/23.0"); 
    curl_setopt($ch, CURLOPT_HEADER, 0); // пустые заголовки
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); // возвратить то что вернул сервер
    curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1); // следовать за редиректами
    curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 30);// таймаут
    curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
    curl_setopt($ch, CURLOPT_COOKIESESSION, false);
    curl_setopt($ch, CURLOPT_COOKIEJAR, $cookiefile); // сохранять куки в файл
    curl_setopt($ch, CURLOPT_POST, true);
   
    $str = curl_exec($ch);
    $dom = new DOMDocument();
    $dom->loadHTML($str);       
    $imgfind = $dom->getElementsByTagName('img');
    $inputFind = $dom->getElementsByTagName('input');
    foreach ($inputFind as $key) {
        $secret[] = $key->getAttribute('value');
    }

    foreach($imgfind as $im) {
        $test = parse_url($im->getAttribute('src'));
        if($test['host'] == 'ext.captcha.yandex.net'){
            file_put_contents('captcha.png', file_get_contents($im->getAttribute('src')));
            $secret[1] = reCaptcha(); //получаем каптчу через сервис ruCaptha
        }
    }

    $postLoginFields = array();
    $postLoginFields['track_id'] = $secret[0];
    $postLoginFields['language'] = 'ru';
    $postLoginFields['firstname'] = $login;
    $postLoginFields['lastname'] = $login;
    $postLoginFields['login'] = $login;
    $postLoginFields['password'] = $pass;
    $postLoginFields['password_confirm'] = $pass;
    $postLoginFields['human-confirmation'] = 'captcha';
    $postLoginFields['hint_question_id'] = 15;
    $postLoginFields['hint_answer'] = $login;
    $postLoginFields['key'] = $secret[20];
    $postLoginFields['captcha_mode'] = 'text';
    $postLoginFields['answer'] = $secret[1];
    $postLoginFields['eula_accepted'] = true;

    curl_setopt($ch, CURLOPT_COOKIEFILE, $cookiefile);
    curl_setopt($ch, CURLOPT_POSTFIELDS, http_build_query($postLoginFields));
    $output = curl_exec($ch);
    echo $output;
    echo '<pre>';
    var_dump($postLoginFields);
    echo '</pre>';
    // return $output;

}
regYandexAcc('Aleks123qwerty122', "asdasfasfasfaa3312");

I understand that the problem is that curl_exec($ch); terminates the connection. That you need to somehow send cookies or headers. But how to do it, I have no idea. Tell me plz...

Answer 1

check the captcha, firstly, for 100-1000 attempts
, no one promises you to enter the characters of your sent captcha)))
secondly, you will achieve the identity of the
browser headers and scripts
