from scrapy.selector import Selector
from  scrapy.http import Request
from zhuanti.items import ZhuantiItem
class zhuanti(CrawlSpider):
    name = 'zhuanti'
    start_urls=['https://www.jianshu.com/recommendations/collections?page=1&order_by=hot']

    def parse(self,response):
        item=ZhuantiItem()
        selector=Selector(response)
        infos=selector.xpath('//div[@class="col-xs-8"]')
        for info in infos:
            try:
                name=info.xpath('//div/a/h4/text()').extract()[0]
                content=info.xpath('//div/a/p/text()').extract()[0]
                article=info.xpath('//div/div/a/text()').extract()[0]
                fans = info.xpath('//div/div/text()').extract()[0]

                item['name']=name
                item['content'] = content
                item['article'] = article
                item['fans'] = fans

                yield item
            except IndexError:
                pass

        urls=['https://www.jianshu.com/recommendations/collections?page={}&order_by=hot'.format(str(a))for a in range(2,39)]
        for url in urls:
            yield Request(url,callback=self.parse)
