A Scrapy middleware that solves CAPTCHAs found on web pages

The middleware uses 2 kind of sub-components:

• Engines: responsible for finding captcha on page and submitting it
• Solvers: convert CAPTCHA image file to text

To use decaptcha in your Scrapy project, you must set some variables in your settings.py file:

# enable/disable middleware
DECAPTCHA_ENABLED = 1

# set engines classes
DECAPTCHA_ENGINES = {
    'decaptcha.engines.recaptcha.RecaptchaEngine': 500,
}

# set solver class
DECAPTCHA_SOLVER = 'decaptcha.solvers.deathbycaptcha.DeathbycaptchaSolver'

# configure deathbycaptcha solver
DECAPTCHA_DEATHBYCAPTCHA_USERNAME = 'your-username'
DECAPTCHA_DEATHBYCAPTCHA_PASSWORD = 'your-password'

• decaptcha.engines.recaptcha.RecaptchaEngine - Google reCAPTCHA engine

• decaptcha.solvers.deathbycaptcha.DeathbycaptchaSolver - Solver that uses http://www.deathbycaptcha.com/ service
