最近迷上了爬虫技术

python 爬虫，目前我还在进一步学习阶段，有志同道合的兄弟们，可以一起探讨。

import requests
import os
from lxml import etree

if __name__ == "__main__":
    parse = etree.HTMLParser(encoding="utf-8")
    headers = {
        'User-Agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 '
                      '(HTML, like Gecko) Chrome/98.0.4758.81 Safari/537.36'
    }
    url = "https://域名/index_4.html"
    page_text = requests.get(url=url, headers=headers)
    # 通用处理中文乱码的解决方案
    # img_name = img_name.encode('iso-8859-1').decode('gbk')
    page_text.encoding = page_text.apparent_encoding
    page_text = page_text.text
    tree = etree.HTML(page_text, parser=parse)
    li_list = tree.xpath('//ul[@ class = "clearfix"]/li')

    if not os.path.exists('文件夹'):
        os.mkdir('文件夹')

    for li in li_list:
        img_name = li.xpath('./a/img/@alt')[0] + '.jpg'
        img_src = "https://域名/" + li.xpath('./a/img/@src')[0]
        img_data = requests.get(url=img_src, headers=headers).content

        with open('文件夹/' + img_name, 'wb') as fp:
            fp.write(img_data)
            print(img_name)

测试结果：
