BeautifulSoup不会提取所有html [英] BeautifulSoup not extracting all html

问题描述

我们正在尝试从Forever 21网站的此页面获取产品网址(

We are trying to get product urls from this page of Forever 21's site (http://www.forever21.com/Product/Category.aspx?br=f21&category=dress&pagesize=100&page=1). For some reason, BeautifulSoup is not getting the elements with class "item_pic", even though they are in the site html. We have tried using requests, mechanize, selenium, and are having no luck. All the commented code is from previous attempts to get the html (none of which worked). Here is our code:

from bs4 import BeautifulSoup
import urllib
import urllib2
import requests

#driver = webdriver.Firefox()
url = "http://www.forever21.com/Product/Category.aspx?br=f21&category=dress&pagesize=100&page=1"
#r = driver.get(url)
#html = r.read()
#headers = {'User-Agent': 'Mozilla/5.0 (Macintosh; Intel Mac OS X 10_10_1) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/39.0.2171.95 Safari/537.36'}
#html = requests.get(url, headers=headers)
#response = opener.open(url)
#html = response.read()
html = urllib.urlopen(url).read()
soup = BeautifulSoup(html, "html.parser")
print soup

有什么想法吗?

推荐答案

为了在此处抓取产品网址，您需要使用Selenium.以下代码应为您提供产品ID链接.首先通过硒获取动态生成的源，然后解析您指定的"item_pic" div 的第一个孩子的链接.

In order to scrape the product urls here you need to use Selenium. The following code should give you the product id links. It works by first getting the dynamically generated source through selenium and then parsing the links of the first child of the "item_pic" div you specified.

from bs4 import BeautifulSoup
from selenium import webdriver
import urllib2
import requests

driver = webdriver.Firefox()
url = "http://www.forever21.com/Product/Category.aspx?br=f21&category=dress&pagesize=100&page=1"
driver.get(url)
html = driver.page_source

driver.close()

soup = BeautifulSoup(html, "lxml")

itemList = soup.find_all('div', {'class' : 'item_pic'})

for element in enumerate(itemList):
    print element.a['href']
