Description
To execute your spider, run the following command within your first_scrapy directory −
scrapy crawl first
Where, first is the name of the spider specified while creating the spider.
Once the spider crawls, you can see the following output −
2016-08-09 18:13:07-0400 [scrapy] INFO: Scrapy started (bot: tutorial) 2016-08-09 18:13:07-0400 [scrapy] INFO: Optional features available: ... 2016-08-09 18:13:07-0400 [scrapy] INFO: Overridden settings: {} 2016-08-09 18:13:07-0400 [scrapy] INFO: Enabled extensions: ... 2016-08-09 18:13:07-0400 [scrapy] INFO: Enabled downloader middlewares: ... 2016-08-09 18:13:07-0400 [scrapy] INFO: Enabled spider middlewares: ... 2016-08-09 18:13:07-0400 [scrapy] INFO: Enabled item pipepnes: ... 2016-08-09 18:13:07-0400 [scrapy] INFO: Spider opened 2016-08-09 18:13:08-0400 [scrapy] DEBUG: Crawled (200) <GET http://www.dmoz.org/Computers/Programming/Languages/Python/Resources/> (referer: None) 2016-08-09 18:13:09-0400 [scrapy] DEBUG: Crawled (200) <GET http://www.dmoz.org/Computers/Programming/Languages/Python/Books/> (referer: None) 2016-08-09 18:13:09-0400 [scrapy] INFO: Closing spider (finished)
As you can see in the output, for each URL there is a log pne which (referer: None) states that the URLs are start URLs and they have no referrers. Next, you should see two new files named Books.html and Resources.html are created in your first_scrapy directory.
