我的蜘蛛:
import scrapy
class lngspider(scrapy.Spider):
name = 'scrapylng'
user_agent = 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/66.0.3359.181 Safari/537.36'
start_urls = ['https://directory.lubesngreases.com/LngMain/includes/themes/MuraBootstrap3/remote/api?fn=searchcompany&name&query&STATE&brand&COUNTRY&query2&mode=advanced&filters=%7B%7D&page=1&datatype=html']
def parse(self,response):
for company in response.css('div.company-item row'):
yield{
'name' : products.css('class.CompanyHead').get()
}
输出量:

按热度按时间c7rzv4ha1#
我在
parse()
中添加了print('url:', response.url)
,我看到它运行此函数。第一个问题是您以错误方式使用
CSS
这个
div
有两个类company-item
和row
,你必须使用两个点(没有空格)使用
div.company-item row
表示<div class="company-item"> <row>
第二个问题是您使用了不存在的变量
product
。它必须是
company.css()
,而不是product.css()
第三个问题是,它必须是
span
,而不是company.css()
中的class
,否则您应该跳过class
但这会给出
HTML
,您需要伪选择器::text
才能从HTML
中只获取文本第一个
