用BeautifulSoup和Requests刮掉多个分页链接 [英] Scraping multiple paginated links with BeautifulSoup and Requests
问题描述
现在,我尝试用span class ='page-list来隔离所有的分页按钮,但即使这样也行不通,理想情况下,如何使抓取工具继续点击下一个,直到它抓住了所有页面上的所有产品。我该如何做到这一点?
真的很感激任何输入
from bs4 import BeautifulSoup
导入请求
base_url =http://www.dabs。 com
page_array = []
$ b $ def get_pages():
html = requests.get(base_url)
soup = BeautifulSoup(html.content,html。解析器)
page_list = soup.findAll('span',class =page-list)
pages = page_list [0] .findAll('a')
页面中的页面:
page_array.append(page.get('href'))
def scrape_page(page):
html = requests.get base_url)
soup = BeautifulSoup(html.content,html.parser)
Product_table = soup.findAll(table)
Products = P roduct_table [0] .findAll(tr)
if len(soup.findAll('tr'))> 0:
产品=产品[1:]
在产品行中:
cells = row.find_all('td')
data = {
'description':cells [0] .get_text(),
'price':cells [1] .get_text()
}
打印数据
get_pages ()
[page_array中的页面的scrape_page(base_url +页面)]
导入请求
from bs4导入BeautifulSoup为bs
url ='www.dabs.com/category/computing/11001/'
base_url ='http://www.dabs.com '
r = requests.get(url)
soup = bs(r.text)
elm = soup.find('a',{'title' :'Next'})
next_page_link = base_url + elm ['href']
希望有所帮助。
Python Beginner here. I'm trying to scrape all products from one category on dabs.com. I've managed to scrape all products on a given page, but I'm having trouble iterating over all the paginated links.
Right now, I've tried to isolate all the pagination buttons with the span class='page-list" but even that isn't working. Ideally, I would like to make the crawler keep clicking next until it has scraped all products on all pages. How can I do this?
Really appreciate any input
from bs4 import BeautifulSoup
import requests
base_url = "http://www.dabs.com"
page_array = []
def get_pages():
html = requests.get(base_url)
soup = BeautifulSoup(html.content, "html.parser")
page_list = soup.findAll('span', class="page-list")
pages = page_list[0].findAll('a')
for page in pages:
page_array.append(page.get('href'))
def scrape_page(page):
html = requests.get(base_url)
soup = BeautifulSoup(html.content, "html.parser")
Product_table = soup.findAll("table")
Products = Product_table[0].findAll("tr")
if len(soup.findAll('tr')) > 0:
Products = Products[1:]
for row in Products:
cells = row.find_all('td')
data = {
'description' : cells[0].get_text(),
'price' : cells[1].get_text()
}
print data
get_pages()
[scrape_page(base_url + page) for page in page_array]
Their next page button has a title of "Next" you could do something like:
import requests
from bs4 import BeautifulSoup as bs
url = 'www.dabs.com/category/computing/11001/'
base_url = 'http://www.dabs.com'
r = requests.get(url)
soup = bs(r.text)
elm = soup.find('a', {'title': 'Next'})
next_page_link = base_url + elm['href']
Hope that helps.
