可以使用Python中的requests库和BeautifulSoup库来实现爬取网页中的下载列表。以下是一个简单的示例代码:
import requests
from bs4 import BeautifulSoup
url = 'http://example.com/download-list'
response = requests.get(url)
if response.status_code == 200:
soup = BeautifulSoup(response.content, 'html.parser')
download_links = []
for link in soup.find_all('a'):
if link.get('href') and link.get('href').endswith('.zip'):
download_links.append(link.get('href'))
for download_link in download_links:
download_response = requests.get(download_link)
with open(download_link.split('/')[-1], 'wb') as f:
f.write(download_response.content)
print('下载完成!')
else:
print('无法访问网页')
在以上代码中,首先使用requests库获取网页内容,然后使用BeautifulSoup库解析网页,找出所有包含下载链接的标签,并筛选出以’.zip’结尾的链接。最后,依次下载这些链接对应的文件,并保存到本地。
