如何下载网页上的图片

import requests
from bs4 import BeautifulSoup
import os

def download_images(url, folder='images'):
    if not os.path.exists(folder):
        os.makedirs(folder)
    
    response = requests.get(url)
    soup = BeautifulSoup(response.text, 'html.parser')
    
    for img in soup.find_all('img'):
        img_url = img.get('src')
        if img_url:
            try:
                img_data = requests.get(img_url).content
                with open(os.path.join(folder, os.path.basename(img_url)), 'wb') as handler:
                    handler.write(img_data)
                print(f"Downloaded {img_url}")
            except Exception as e:
                print(f"Failed to download {img_url}: {e}")

# 使用示例
download_images('http://example.com/page-with-images')
