spider

import scrapy
class QuotesSpider(scrapy.Spider):
    name = 'quotes'                     #蜘蛛的名字
    def start_requests(self):           #包含了spider在启动时进行爬取的URL列表，该函数必须返回Request对象或者生成器

        allowed_domains = ['quotes.toscrape.com']    #蜘蛛的范围
        urls = [
            'http://www.quotes.toscrape.com/page/1/'
            'http://www.quotes.toscrape.com/page/2/'
        ]                                   #从哪里开始爬
        for url in urls:
            yield scrapy.Request(url=url,callback=self.parse)

    def parse(self,response):           #该函数负责解析返回的数据，提取数据以及生成需要进一步处理的URL的Request对象
        page = response.url.split('/')[-2]
        filename = 'quotes-%s.html'%page
        with open(filename,"wb") as f:
            f.write(response.body)
        self.log('Save file %s'%filename)
