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：
