【问题描述】：
我是 Python Beautiful Soup 的新手，我对 html 或 js 了解不多。我尝试使用 bs4 下载此page 中的所有 xls 文件，但似乎 bs4 在“附件”部分下找不到链接。有人可以帮帮我吗？
我当前的代码是：
"""
Scrapping of all county-level raw data from
http://www.countyhealthrankings.org for all years. Data stored in RawData
folder.
Code modified from https://null-byte.wonderhowto.com/how-to/download-all-
pdfs-webpage-with-python-script-0163031/
"""
from bs4 import BeautifulSoup
import urlparse
import urllib2
import os
import sys
"""
Get all links
"""
def getAllLinks(url):
page=urllib2.urlopen(url)
soup = BeautifulSoup(page.read(),"html.parser")
links = soup.find_all('a', href=True)
return links
def download(links):
for link in links:
#raw_input("Press Enter to continue...")
#print link
#print "------------------------------------"
#print os.path.splitext(os.path.basename(link['href']))
#print "------------------------------------"
#print os.path.splitext(os.path.basename(link['href']))[1]
suffix = os.path.splitext(os.path.basename(link['href']))[1]
if os.path.splitext(os.path.basename(link['href']))[1] == '.xls':
print link #cannot find anything
currentLink = urllib2.urlopen(link)
links =
getAllLinks("http://www.countyhealthrankings.org/app/iowa/2017/downloads")
download(links)
（顺便说一下，我想要的链接看起来像this。）
谢谢！
