Project Description

scrapy-crawlera provides easy use of Crawlera with Scrapy.

Installation

You can install scrapy-crawlera using pip:

pip install scrapy-crawlera

Configuration

  • Add the Crawlera middleware including it into the DOWNLOADER_MIDDLEWARES in your settings.py file:

    DOWNLOADER_MIDDLEWARES = {
        ...
        'scrapy_crawlera.CrawleraMiddleware': 610
    }
    
  • Then there are two ways to enable it.

    • Through settings.py:

      CRAWLERA_ENABLED = True
      CRAWLERA_APIKEY = 'apikey'
      
    • Through spider attributes:

      class MySpider:
          crawlera_enabled = True
          crawlera_apikey = 'apikey'
      

How to use it

With the middleware, the usage of crawlera is automatic, every request will go through crawlera without nothing to worry about.

Remember that you are now making request to Crawlera, and the Crawlera service will be the one actually making the requests to the different sites.

If you need to specify special Crawlera Headers, just apply them as normal Scrapy Headers.

Here we have an example of specifying a Crawlera header into a Scrapy request:

scrapy.Request(
    'http://example.com',
    headers={
        'X-Crawlera-Max-Retries': 1,
        ...
    },
)

Remember that you could also set which headers to use by default by all requests with DEFAULT_REQUEST_HEADERS
