【python】爬取斗鱼直播照片保存到本地目录

import requests
from bs4 import BeautifulSoup
import os
 
# 爬取指定大小的图片
def crawl_images(url, image_size):
    response = requests.get(url)
    if response.status_code == 200:
        soup = BeautifulSoup(response.text, 'html.parser')
        images = soup.find_all('img', {'class': 'img-responsive lazy image_dta'})
        for image in images:
            if image_size in image['data-original']:
                image_url = image['data-original']
                save_image(image_url)
 
# 保存图片到本地
def save_image(image_url):
    response = requests.get(image_url)
    if response.status_code == 200:
        file_path = 'images/' + image_url.split('/')[-1]
        with open(file_path, 'wb') as file:
            file.write(response.content)
            print(f'图片 {image_url} 已保存到 {file_path}')
    else:
        print(f'图片 {image_url} 下载失败')
 
# 主函数
def main():
    # 要爬取的斗鱼直播URL
    url = 'http://www.dantiao.com/live/girl'
    # 设置想要爬取的图片大小
    image_size = '640x360'
    crawl_images(url, image_size)
 
if __name__ == '__main__':
    main()

在这个示例中，我们定义了crawl_images函数来爬取指定大小的图片，save_image函数来保存图片到本地，并在main函数中调用这些函数。这个简单的爬虫示例展示了如何使用Python网络请求库requests和HTML解析库BeautifulSoup来爬取网页上的图片资源。
