Scrapy Zenscrape Middleware

Acknowledgements

Thanks to arimbr and ScrapingBee, this is adaptation of their work.

Installation

pip install scrapy-zenscrape

Configuration

Add your ZENSCRAPE_API_KEY and the ZenscrapeMiddleware to your project settings.py. Don't forget to set CONCURRENT_REQUESTS according to your Zenscrape plan.

ZENSCRAPE_API_KEY = 'REPLACE-WITH-YOUR-API-KEY'

DOWNLOADER_MIDDLEWARES = {
    'scrapy_zenscrape.ZenscrapeMiddleware': 700,
}

CONCURRENT_REQUESTS = 1

Usage

Inherit your spiders from ZenscrapeSpider and yield a ZenscrapeRequest.

Below you can see an example from the spider in httpbin.py.

from scrapy import Spider
from scrapy_zenscrape import ZenscrapeSpider, ZenscrapeRequest

class HttpbinSpider(Spider):
    name = 'httpbin'
    start_urls = [
        'https://httpbin.org',
    ]

    def start_requests(self):
        for url in self.start_urls:
            yield ZenscrapeRequest(url, params={
                # 'render': False,
                # 'block_ads': True,
                # 'block_resources': False,
                # 'premium': True,
                # 'location': 'fr',
                # 'wait_for': 5,
                # 'wait_for_css': '#swagger-ui',
            },
            headers={
                # 'Accept-Language': 'En-US',
            },
            cookies={
                # 'name_1': 'value_1',
            })

    def parse(self, response):
        ...

You can pass Zenscrape parameters in the params argument of a ZenscrapeRequest. Headers and cookies are passed like a normal Scrapy Request. ZenscrapeRequests formats all parameters, headers and cookies to the format expected by the API.

Examples

Add your API key to settings.py.

To run the examples you need to clone this repository. In your terminal, go to examples/httpbin/httpbin and run the example spider with:

scrapy crawl httpbin
