that request finishes. Using this, you can build complex crawlers that follow links according to rules you define, and extract different kinds of data depending on the page it’s visiting. In our example of following links, check out the CrawlSpider class for a generic spider that implements a small rules engine that you can use to write your crawlers on top of it. Also, a common pattern is to build an Example: –cbkwargs=’{“foo” : “bar”}’ • --pipelines: process items through pipelines • --rules or -r: use CrawlSpider rules to discover the callback (i.e. spider method) to use for parsing the response • --noitems:
