Works for solving captchas when scraping Google, YouTube, and other sites that use ReCaptcha.

ReCaptcha V2

Official PHP library from 2captcha did not work too well, so this was built.

• https://2captcha.com/blog/google-search-recaptcha
• https://2captcha.com/blog/update-google-recaptcha

<?php

use CaptchaSolver\TwoCaptcha\Client;
use CaptchaSolver\TwoCaptcha\InRequest;

$captcha = new Client([
    'key' => 'API_KEY_GOES_HERE',
    'proxy' => null // optional
]);

$request = new InRequest([
    'googlekey' => '',
    'pageurl' => ''
]);

$response = $captcha->send($request);
$id = $response->getResult();

sleep(45);

$response = $captcha->getResult($id);
$solution = $response->getSolution();

// or combine the two calls into one that polls automatically every 5 seconds and times out after 90 seconds:

$response = $captcha->solveReCaptchaV2($request, 90);

$solution should now hold a "solution" token that looks something like this:

submit the captcha form given to you with that solution as g-recaptcha-response field along with any other relevant form fields, and you are done!

Installation

composer require athlon1600/php-captcha-solver

Testing

A useful mini web-application can be launched via:

php -S localhost:8000 -t public

and then visit:
http://localhost:8000/2captcha.php

Known issues

Sometimes solving the captcha will not get you through, and instead you would just get this message at the end:

so at this point there is not much else you can do other than not make any requests for a while until Google automatically unblocks your IP address.

Misc stuff

Make 'g-recaptcha-response' textarea visible on page:

document.getElementById('g-recaptcha-response').style = null;
