CrawlSpider(class scrapy.spiders.CrawlSpider)
Spider类:
只爬取start_urls列表中的网页
CrawlSpider类:
定义了一些规则(rule)来提供跟进link的机制,从爬取的网页中获取link并继续爬取
LinkExtractors类:
用于提取链接,该类的extract_links()方法接收一个Response对象,返回一个scrapy.link.Link对象
该类需要实例化一次,并且extract_links()方法会根据不同的response调用多次提取链接
class scrapy.linkextractors.LinkExtractor(
allow = (), # 满足括号中'正则表达式'的值会被提取,如果为空则全部匹配(常用)
deny = (), # 与这个正则表达式不匹配的URL一定不提取
allow_domains = (), # 会被提取的链接的domains(常用)
deny_domains = (), # 一定不会被提取链接的domains
deny_extensions = None,
restrict_xpaths = (), # 使用xpath表达式,和allow共同作用过滤链接
tags = ('a','area'),
attrs = ('href'),
canonicalize = True,
unique = True,
process_value = None
)
rules:
包含一个或多个Rule对象,每个Rule对爬取网站的动作定义了特定操作
class scrapy.spiders.Rule(
link_extractor, # 是一个LinkExtractor对象,定义需要提取的链接
