What is reCAPTCHA

reCAPTCHA is a CAPTCHA system designed by Google to differentiate between human users and bots. It often presents users with tasks like identifying images or simply checking a box labeled "I'm not a robot." While these tasks are simple for humans, they pose a significant challenge to bots, which is exactly the point.

reCAPTCHA comes in several versions, each designed to differentiate between humans and bots in unique ways:

• reCAPTCHA v1: The original version required users to decipher and type distorted text into a text box.
• reCAPTCHA v2: This version introduced the familiar checkbox where users confirm their human identity by clicking "I'm not a robot." Occasionally, it may prompt users to select specific images from a grid to verify their authenticity.
• reCAPTCHA v3: Unlike earlier versions, reCAPTCHA v3 operates silently in the background, analyzing user behavior to assign a risk score that indicates whether the user is likely human or a bot. This version offers a seamless experience, requiring no direct interaction from the user.

In this blog, we'll focus on solving reCAPTCHA V2 and V3, which are widely used to distinguish genuine users from bots. reCAPTCHA V2 typically displays a checkbox with the prompt "I'm not a robot," while reCAPTCHA V3 may appear as an invisible badge, performing its checks without interrupting the user experience. Here's a visual example of reCAPTCHA in action:

Why Use Playwright for Web Scraping?

Playwright's ability to simulate real user interactions in multiple browsers makes it ideal for web scraping. It can handle complex scenarios, such as filling out forms, navigating through pages, and interacting with dynamic content. However, when a website employs reCAPTCHA, Playwright alone cannot solve the challenge—this is where CapSolver comes in.

Installation and Setup

To solve reCAPTCHA challenges using Playwright, you'll need to install the playwright-recaptcha library. This library requires FFmpeg to be installed on your system, which is essential for transcribing reCAPTCHA v2 audio challenges.

You can install the required library and FFmpeg using the following commands based on your operating system:

Library Installation:

pip install playwright-recaptcha

FFmpeg Installation:

• Debian:

  apt-get install ffmpeg

• MacOS:

  brew install ffmpeg

• Windows:

  winget install ffmpeg

Note: Ensure that the ffmpeg and ffprobe binaries are in your system's PATH so that pydub can locate them.

Integrating CapSolver into Your Workflow

Once you have the necessary tools installed, you can integrate CapSolver into your web scraping project to handle reCAPTCHA challenges automatically. Here's an example of how to do this using Python:

Sample Code for Solving reCAPTCHA v2 with CapSolver

# pip install requests
import requests
import time

# TODO: set your config
api_key = "YOUR_API_KEY"  # your api key of capsolver
site_key = "6Le-wvkSAAAAAPBMRTvw0Q4Muexq9bi0DJwx_mJ-"  # site key of your target site
site_url = "https://www.google.com/recaptcha/api2/demo"  # page url of your target site


def capsolver():
    payload = {
        "clientKey": api_key,
        "task": {
            "type": 'ReCaptchaV2TaskProxyLess',
            "websiteKey": site_key,
            "websiteURL": site_url
        }
    }
    res = requests.post("https://api.capsolver.com/createTask", json=payload)
    resp = res.json()
    task_id = resp.get("taskId")
    if not task_id:
        print("Failed to create task:", res.text)
        return
    print(f"Got taskId: {task_id} / Getting result...")

    while True:
        time.sleep(3)  # delay
        payload = {"clientKey": api_key, "taskId": task_id}
        res = requests.post("https://api.capsolver.com/getTaskResult", json=payload)
        resp = res.json()
        status = resp.get("status")
        if status == "ready":
            return resp.get("solution", {}).get('gRecaptchaResponse')
        if status == "failed" or resp.get("errorId"):
            print("Solve failed! response:", res.text)
            return


token = capsolver()
print(token)

Sample Code for Solving reCAPTCHA v3 with CapSolver

# pip install requests
import requests
import time

# TODO: set your config
api_key = "YOUR_API_KEY"  # your api key of capsolver
site_key = "6Le-wvkSAAAAAPBMRTvw0Q4Muexq9bi0DJwx_kl-"  # site key of your target site
site_url = "https://www.google.com"  # page url of your target site


def capsolver():
    payload = {
        "clientKey": api_key,
        "task": {
            "type": 'ReCaptchaV3TaskProxyLess',
            "websiteKey": site_key,
            "websiteURL": site_url,
            "pageAction": "login",
        }
    }
    res = requests.post("https://api.capsolver.com/createTask", json=payload)
    resp = res.json()
    task_id = resp.get("taskId")
    if not task_id:
        print("Failed to create task:", res.text)
        return
    print(f"Got taskId: {task_id} / Getting result...")

    while True:
        time.sleep(1)  # delay
        payload = {"clientKey": api_key, "taskId": task_id}
        res = requests.post("https://api.capsolver.com/getTaskResult", json=payload)
        resp = res.json()
        status = resp.get("status")
        if status == "ready":
            return resp.get("solution", {}).get('gRecaptchaResponse')
        if status == "failed" or resp.get("errorId"):
            print("Solve failed! response:", res.text)
            return


token = capsolver()
print(token)

Best Practices for CAPTCHA Handling in Web Scraping

1. Use Proxies: When scraping websites, it's important to use proxies to avoid getting banned or rate-limited.

2. Rotate User-Agents: To further avoid detection, rotate your user-agent strings to mimic different browsers and devices.

3. Respect Website Policies: Always check the website’s robots.txt file and comply with its scraping rules. Avoid overloading servers with too many requests.

4. Handle Errors Gracefully: Implement error handling in your scripts to manage scenarios where CAPTCHA solving fails. This will help maintain the robustness of your scraping projects.
