1. Installing Selenium and Required Components

First, install Selenium and the necessary components using pip:

pip install selenium

Make sure to download and set up the appropriate drivers for the browser you plan to use (e.g., ChromeDriver for Google Chrome, GeckoDriver for Firefox).

2. Configuring the CapSolver Extension

Download the CapSolver extension and unzip it into a directory named ./CapSolver.Browser.Extension at the root of your project.

Configuration Settings

The extension provides various settings, including automatic CAPTCHA solving and proxy support. These are defined in the ./assets/config.json file. Below is an example configuration:

{
  "apiKey": "YourApiKey",
  "useCapsolver": true,
  "useProxy": false,
  "proxyType": "http",
  "hostOrIp": "",
  "port": "",
  "proxyLogin": "",
  "proxyPassword": "",
  "enabledForBlacklistControl": false,
  "blackUrlList": [],
  "enabledForRecaptcha": true,
  "enabledForRecaptchaV3": true,
  "enabledForHCaptcha": true,
  "enabledForFunCaptcha": true,
  "reCaptchaMode": "token",
  "hCaptchaMode": "click",
  "reCaptchaDelayTime": 0,
  "hCaptchaDelayTime": 0,
  "reCaptchaRepeatTimes": 10,
  "reCaptcha3RepeatTimes": 10,
  "hCaptchaRepeatTimes": 10,
  "funCaptchaRepeatTimes": 10
}

• API Key: Insert your CapSolver API key in the apiKey field. You can obtain your API key from the CapSolver Dashboard.
• Modes: For this example, reCaptchaMode is set to token, but you can also use the click mode for reCaptcha.

3. Setting Up Selenium to Solve reCaptcha with CapSolver Extension

Now, let's set up Selenium WebDriver and configure it to use the CapSolver extension. Below is an example using ChromeDriver in Python:

from selenium import webdriver
from selenium.webdriver.chrome.options import Options
from selenium.webdriver.common.by import By
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC
import os

def main():
    extension_path = os.path.abspath('./CapSolver.Browser.Extension')
    chrome_options = Options()
    chrome_options.add_argument(f'--load-extension={extension_path}')

    driver = webdriver.Chrome(options=chrome_options)
    driver.get('https://www.google.com/recaptcha/api2/demo')

    # Wait for the captcha to be solved automatically by the extension
    WebDriverWait(driver, 10).until(EC.element_to_be_clickable((By.ID, 'recaptcha-demo-submit')))

    # Proceed with form submission or any other actions post-captcha solving
    driver.quit()

if __name__ == "__main__":
    main()

4. Full Code Example

The Python script provided above is ready to run. Ensure your environment is correctly set up with the necessary packages and drivers, and adjust the extension_path if needed to point to your CapSolver extension directory.

By following these steps, you've successfully configured Selenium with the CapSolver Extension to solve reCaptcha v2 using Python. This method can be easily adapted to solve other types of CAPTCHAs by making minor adjustments.
