The functionality of the scrapy. Third, data processing flowScrapy 's entire data processing process is controlled by the scrapy engine, which operates mainly in the following ways:The engine opens a domain name, when the spider handles the domain name and lets the spider get the first crawl URL. The engine gets the first URL to crawl from the spider , and then dispatches it as a request in the schedule. The engine gets the page that crawls next from the dispatch.The schedule returns the next
