从网站批量下载图片的最佳方法

import requests
from bs4 import BeautifulSoup
import os

# 目标网站URL
url = "https://example.com"

# 发起HTTP请求获取网页内容
response = requests.get(url)
html_content = response.text

# 使用BeautifulSoup解析HTML内容
soup = BeautifulSoup(html_content, "html.parser")

# 提取所有图片的URL
image_urls = []
for img_tag in soup.find_all("img"):
    image_url = img_tag.get("src")
    if image_url.startswith("http"):
        image_urls.append(image_url)
    else:
        image_urls.append(url + image_url)

# 创建保存图片的目录
save_dir = "images"
if not os.path.exists(save_dir):
    os.makedirs(save_dir)

# 下载图片
for i, image_url in enumerate(image_urls):
    response = requests.get(image_url)
    image_name = f"image_{i}.jpg"
    save_path = os.path.join(save_dir, image_name)
    with open(save_path, "wb") as f:
        f.write(response.content)
    print(f"下载图片 {image_name} 完成")

print("批量下载图片完成")
