Yet another camoufox integration for scrapy.

scrapy-playfox: Yet another camoufox integration for Scrapy

A Scrapy download handler "extended" on scrapy-playwright. scrapy-playfox plays a role like glue that sticks scrapy-playwright and camoufox together without touching any of them.

Why Camoufox?

Camoufox is the most modern, effective & future-proof open source solution for avoiding bot detection and intelligent fingerprint rotation. It's perfect choice for scraping sort of strong anti-bot websites.

Installation

scrapy-playfox is available on PyPI and can be installed with pip:

pip install scrapy-playfox

Camoufox is defined as a dependency so it gets installed automatically, however it might be necessary to install the browser that will be used:

camoufox fetch

Activation

Download handler

Replace the default http and/or https Download Handlers through DOWNLOAD_HANDLERS:

# settings.py
DOWNLOAD_HANDLERS = {
    "http": "scrapy_playfox.handler.ScrapyPlaywrightDownloadHandler",
    "https": "scrapy_playfox.handler.ScrapyPlaywrightDownloadHandler",
}

If this handler is only used by specified spiders, you can add custom settings in your spider like this:

import scrapy

class MySpider(scrapy.Spider):
    custom_settings = {
        'DOWNLOAD_HANDLERS': {
            'http': 'scrapy_playfox.handler.ScrapyPlaywrightDownloadHandler',
            'https': 'scrapy_playfox.handler.ScrapyPlaywrightDownloadHandler',
        },
    }

Note that the ScrapyPlaywrightDownloadHandler class inherits from the default http/https handler. Unless explicitly marked, requests will be processed by the regular Scrapy download handler.

Twisted reactor

Install the asyncio-based Twisted reactor:

# settings.py
TWISTED_REACTOR = "twisted.internet.asyncioreactor.AsyncioSelectorReactor"

This is the default in new projects since Scrapy 2.7.

Common Settings

This is the commonly used settings in your spider. Learn more from Camoufox and scrapy-playwright documentations.

from browserforge.fingerprints import Screen

custom_settings = {
    'PLAYWRIGHT_LAUNCH_OPTIONS': {
        'headless': False,
        'humanize': True,
        'screen': Screen(max_width=1280, max_height=800),
        'geoip': False,
    },
    'PLAYWRIGHT_CONTEXTS': {
        'persistent': {
            'user_data_dir': 'playfox_data',
        }
    }
}

Basic Usage

Same as scrapy-playwright.

import scrapy

class MySpider(scrapy.Spider):
    name = "awesome"

    def start_requests(self):
        # GET request
        yield scrapy.Request("https://httpbin.org/get", meta={"playwright": True})
        # POST request
        yield scrapy.FormRequest(
            url="https://httpbin.org/post",
            formdata={"foo": "bar"},
            meta={"playwright": True},
        )

    def parse(self, response, **kwargs):
        # 'response' contains the page as seen by the browser
        return {"url": response.url}
