Asynchronous web crawler. Handles each depth level to completion before moving on. Only finds links that are hosted on the main domain or subdomain of the user's original choosing.
- Tested on Kali 1.0.6
- Python 2.7
- gevent 1.0
- requests 1.2.0+
python crawler.py -u "http://stallman.org" -d 5 -p 100
Crawl http://stallman.org for links and follow them 5 pages deep; default is 1. Open 100 links at a time; default is 500.
Uses gevent for concurrency, lxml for html parsing and link finding, and 2 queues to speed up processing. One queue gets all the unique links that have been found which will then be opened with requests. As those jobs are running in parallel, any scraped html from completed ones is sent to the second queue which will feed the html processor that finds links.
