Description

This example shows how to automate the solution of Yandex SmartCaptcha on the demo captcha page https://captcha-api.yandex.ru/demo. For automation we use the library Puppeteer and the captcha solving service 2captcha.com. For correct work of the example you need APIKEY, for this you need to have an account in the service 2captcha.com, APIKEY is displayed in your personal cabinet.

Usage

Clone

git clone https://github.com/dzmitry-duboyski/solving-yandex-smart-captcha-using-puppeteer.git

install dependens

npm install

configure

Set up you APIKEY in ./index.js#L3

APIKEY is specified in your 2captcha.com account. Before copying APIKEY, make sure that the "developer" role is selected in your account.

Start

npm run start

Source code

import puppeteer from "puppeteer";
import { Solver } from "2captcha-ts";
const solver = new Solver("<Your 2captcha APIKEY>");

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

  const page = await browser.newPage();

  // Open target page
  await page.goto("https://captcha-api.yandex.ru/demo");
  await page.waitForSelector("#captcha-container");
  await page.waitForSelector("iframe[data-testid='checkbox-iframe'");

  // Enter data
  await page.$eval("#name", (el) => (el.value = ""));
  await page.type("#name", "John Doe", { delay: 100 });

  // Get the `sitekey` parameter from the current page
  const sitekey = await page.evaluate(() => {
    return document
      .querySelector("#captcha-container")
      .getAttribute("data-sitekey");
  });

  // Send a captcha to the 2captcha service to get a solution
  const res = await solver.yandexSmart({
    pageurl: "https://captcha-api.yandex.ru/demo",
    sitekey: sitekey,
  });

  console.log(res);

  // The resulting solution
  const captchaAnswer = res.data;

  // Use the resulting solution on the page
  const setAnswer = await page.evaluate((captchaAnswer) => {
    document.querySelector("input[data-testid='smart-token']").value =
      captchaAnswer;
  }, captchaAnswer);

  // Click on the 'Submit' button to check the captcha solution
  await page.click("#smartcaptcha-demo-submit");

  await page.waitForSelector(".greeting");

  console.log("Captcha solved successfully!!!");

  browser.close();
})();
