Python爬取某个网站的图片

最近需要将某个网站的图片爬取下来，想尽了很多办法，后来使用python的爬虫技术将其爬取出来

import requests

def download_save_img (img_url, file_name):
    headers ={
        'User-Agent':'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/96.0.4664.45 Safari/537.36'
    }
    r = requests.get(img_url,headers=headers)
    f = open(file_name, mode="wb+")
    f.write(r.content)
    f.close()
    print(file_name + "已完成")


base_url = 'xxxxxxxxxx'
for i in range(0, 229):
    file_name = str(i) + '.jpg'
    img_url = base_url + file_name
    download_save_img(img_url, file_name)
