In the evolving world of web applications, we often come across reCaptcha systems designed to determine whether a user is human or a bot. Fortunately, the reCognizer is a free-to-use AI-based reCaptcha solver that simplifies this process through an easy-to-use API. In this guide, we’ll walk you through the steps to set it up, implement it using Playwright, and tackle common issues.

What You Need

• Python installed on your computer.
• Pip to install packages from PyPI.
• An understanding of using asynchronous and synchronous programming (if necessary).
• Optional: Browser engines like Botright for better integration.

Installation

To install the reCognizer package, simply execute the following command in your terminal:

bash
pip install recognizer

Understanding the Code: An Analogy

Imagine you are teaching a child how to identify different animals based on pictures. Just like you would, reCognizer performs a similar task: it identifies captchas based on the provided images.

In the sample code, a Detector is created much like giving the child a set of images accompanied by a mission (the task_type) to identify a specific animal (the captcha). The images can come in various formats like full-page screenshots or isolated images, making it flexible.

Here’s how that looks in code:

py
from recognizer import Detector

detector = Detector()
task_type: str = "bicycle"
images: accepted_image_types = "recaptcha_image.png"
area_captcha: bool = False

response, coordinates = detector.detect(task_type, images, area_captcha=area_captcha)

Using reCognizer with Playwright

The reCognizer can be leveraged with both synchronous and asynchronous versions of Playwright. Here’s how to use it in both scenarios:

Sync Playwright Example

py
from playwright.sync_api import sync_playwright
from recognizer.agents.playwright import SyncChallenger

def run(playwright):
    browser = playwright.chromium.launch()
    page = browser.new_page()
    challenger = SyncChallenger(page)
    page.goto("https://recaptcha-demo.appspot.com/recaptcha-v2-checkbox-explicit.php")
    challenger.solve_recaptcha()
    browser.close()

with sync_playwright() as playwright:
    run(playwright)

Async Playwright Example

py
import asyncio
from playwright.async_api import async_playwright
from recognizer.agents.playwright import AsyncChallenger

async def run(playwright):
    browser = await playwright.chromium.launch()
    page = await browser.new_page()
    challenger = AsyncChallenger(page)
    await page.goto("https://recaptcha-demo.appspot.com/recaptcha-v2-checkbox-explicit.php")
    await challenger.solve_recaptcha()
    await browser.close()

async def main():
    async with async_playwright() as playwright:
        await run(playwright)

asyncio.run(main())

Troubleshooting

If you encounter issues while using reCognizer, here are a few troubleshooting tips:

• Ensure you are running on an undetected browser engine like Botright. Standard Playwright configurations may lead to captchas being detected improperly.
• Check the input formats; make sure your images comply with the accepted formats as outlined in the documentation.
• Make sure your internet connection is stable, as identifying captchas relies on server communication.
