爬取赶集网二手房数据
scrapy shell http://hz.ganji.com/fang1/shangcheng/
view(response)
获取一个值:
response.xpath(".//*[@id='puid-2929419083']/dl/dd[5]/div[1]/span[1]/text()").extract()
获取一个列表:
response.xpath(".//div[@class='f-list-item ']/dl/dd[5]/div[1]/span[1]/text()").extract()
response.xpath(".//div[@class='f-list-item ']/dl/dd[1]/a/text()").extract()
scrapy list
scrapy crawl zufang
此处是python2和3的坑:
使用ipython建数据库表:
ipython = python -m IPython
import sqlite3
zufang = sqlite3.connect('zufang.sqlite')
create_table = 'create table zufang(title varchar(512),money varchar(128))'
zufang.execute(create_table)
exit
