使用Python从url地址下载所有pdf文件

import requests
from bs4 import BeautifulSoup
import os

def download_pdf(url, folder='pdfs'):
    # 创建文件夹
    if not os.path.exists(folder):
        os.makedirs(folder)
    
    # 发送HTTP请求
    response = requests.get(url)
    response.raise_for_status()
    
    # 解析HTML内容
    soup = BeautifulSoup(response.text, 'html.parser')
    links = soup.find_all('a', href=True)
    
    for link in links:
        href = link['href']
        if href.endswith('.pdf'):
            pdf_url = href
            pdf_name = href.split('/')[-1]
            pdf_path = os.path.join(folder, pdf_name)
            
            # 下载PDF文件
            pdf_response = requests.get(pdf_url)
            pdf_response.raise_for_status()
            
            with open(pdf_path, 'wb') as f:
                f.write(pdf_response.content)
            print(f'Downloaded {pdf_name}')
