Sample code to automate reCAPTCHA solution with Puppeteer

Description

This code example demonstrates how to automate solving a reCAPTCHA using the Puppeteer library. To captcha solving, this example uses the 2captcha.com service. This example solves the captcha located on the page https://2captcha.com/demo/recaptcha-v2. You need to have a 2captcha.com account for the example to work.

How to start:

Cloning

git clone https://github.com/dzmitry-duboyski/solving-recaptcha-using-puppeteer.git

Install dependencies

npm install

Set your APIKEY in .env file

APIKEY is specified in the personal account 2captcha.com. Before copying the APIKEY, check the selected role, the "developer" role must be installed in the personal account.

Start

npm run start

How it works

import puppeteer from "puppeteer";
const APIKEY = process.env.APIKEY;
import { Solver } from "2captcha-ts";
const solver = new Solver(APIKEY);

(async () => {
  const browser = await puppeteer.launch({
    headless: false,
  });

  const page = await browser.newPage();
  await page.setViewport({ width: 1080, height: 1024 });

  await page.goto("https://2captcha.com/demo/recaptcha-v2");
  await page.waitForSelector(".g-recaptcha");

  // Extract the `sitekey` parameter from the page.
  const sitekey = await page.evaluate(() => {
    return document.querySelector(".g-recaptcha").getAttribute("data-sitekey");
  });

  // Get actual page url
  const pageurl = await page.url();

  // Submitting the captcha for solution to the service
  const res = await solver.recaptcha({
    pageurl: pageurl,
    googlekey: sitekey,
  });

  console.log(res);

  // Getting a captcha response including a captcha answer
  const captchaAnswer = res.data;

  // Use captcha answer
  const setAnswer = await page.evaluate((captchaAnswer) => {
    // It is not necessary to make this block visible, it is done here for clarity.
    document.querySelector("#g-recaptcha-response").style.display = "block";
    document.querySelector("#g-recaptcha-response").value = captchaAnswer;
  }, captchaAnswer);

  // Press the button to check the result.
  await page.click('button[type="submit"]');

  // Check result
  await page.waitForSelector("form div pre code");

  const resultBlockSelector = "form div pre code";
  let statusSolving = await page.evaluate((selector) => {
    return document.querySelector(selector).innerText;
  }, resultBlockSelector);

  statusSolving = JSON.parse(statusSolving);
  if (statusSolving.success) {
    console.log("Captcha solved successfully!!!");
  }

  await page.waitForTimeout(5000);
  browser.close();
})();
