Python Dell驱动程序下载

Question

I have been trying my best to get all the dl for drivers using Beautifulsoup4. however it returns links I don't need. I think they are somehow hidden and for the life of me I can not get them out.

here is the page I'm attempting to scrap: http://www.dell.com/support/home/us/en/19/product-support/servicetag/1h1c5p1/drivers

from bs4 import BeautifulSoup
import urllib2

resp = urllib2.urlopen("http://www.gpsbasecamp.com/national-parks")
soup = BeautifulSoup(resp, from_encoding=resp.info().getparam('charset'))

for link in soup.find_all('a', href=True):
print link['href']

Answer 1

The driver links are loaded by js, so usually you'd have to use selenium or similar clients. However in this case, all the driver info is available in json format, in a 'text/preloaded' script tag.

from bs4 import BeautifulSoup
import urllib2
import json

resp = urllib2.urlopen("http://www.dell.com/support/home/us/en/19/product-support/servicetag/1h1c5p1/drivers")
soup = BeautifulSoup(resp, 'html.parser', from_encoding=resp.info().getparam('charset'))
data = json.loads(soup.find('script', type='text/preloaded').text)

for item in data:
    print 'Name', item['driverName']
    print 'Link', item['fileFrmtInfo']['httpFileLocation']
