scrapy笔记(2)爬天天美剧首页

昨天初学了下scrapy,今天测试下效果,看见网上很多都是用豆瓣的页面做测试,那么久换个不一样的,就选择 天天美剧 了

#coding:utf-8
import json
import scrapy
from my_scrapy_project.items import DmozItem
class DmozSpider(scrapy.Spider):
    name = "dmoz"
    allowed_domains = ["ttmeiju.com"]
    start_urls = [
    "http://www.ttmeiju.com/"
    ]

def parse(self, response):
    for sel in response.xpath("//table[contains(@class,'seedtable')]/tr[contains(@class,'Scontent')]"):
        item = DmozItem()
        title = sel.xpath('td[2]/a/text()').extract()[0]
        link = sel.xpath('td[2]/a/@href').extract()
        download = sel.xpath('td[3]/a/@href').extract()
        item['title'] = title
        item['link'] = link
        item['download'] = download
        yield item
  • response.xpath(“//table[contains(@class,’seedtable’)]/tr[contains(@class,’Scontent’)]”) 这段选择了天天美剧首页新的资源板块,意思是选择class为seedtable的table里面class为scontent的tr
  • sel.xpath(‘td[2]/a/text()’).extract()[0] 选择的是片源的名字,通过审查元素,查看源代码可以看到
  • sel.xpath(‘td[3]/a/@href’).extract() 这是资源的各种下载链接

输出结果:

{"download": ["http://pan.baidu.com/s/1i3CcdQd"], "link": ["http://www.ttmeiju.com/seed/38897.html"], "title": "\n\u840c\u5ba0\u4e5f\u75af\u72c2 Pets Wild at Heart S01E02 HR-HDTV \u5927\u5bb6\u5b57\u5e55\u7ec4                    \n                    \n                    "},
{"download": ["http://pan.baidu.com/s/1c0rT2pi"], "link": ["http://www.ttmeiju.com/seed/38896.html"], "title": "\n\u840c\u5ba0\u4e5f\u75af\u72c2 Pet Wild at Heart S01E01 HR-HDTV \u5927\u5bb6\u5b57\u5e55\u7ec4                    \n                    \n                    "},

{"download": ["http://pan.baidu.com/s/1bnxvmFl"], "link": ["http://www.ttmeiju.com/seed/38894.html"], "title": "\n\u7231\u306e\u65c5\u9986 The Love Hotel \u5927\u5bb6\u5b57\u5e55\u7ec4                    \n                    \n                    "},
