代码

百度图片应该是所有图库里最好爬的网站了，先上代码

import requests
import re


def main(url, header, number_photo, photo_path):
    """
    爬虫主函数
    :param url: 网页url
    :param header: 浏览器头部
    :param number_photo: 大致想爬取的图片数量
    :param photo_path: 图片保存地址
    :return: 所有图片的url列表
    """
    headers = {
        "User_Agent": header}
    result = []
    url = re.sub(r'pn=\d+', 'pn={page}', url)
    for i in range(30, number_photo, 30):
        url = url.format(page=i)
        response = requests.get(url, headers=headers)
        html = response.text

        pattern = re.compile(
            '"thumbURL":"(.*?)"'
            , re.S)
        items = re.findall(pattern, html)
        result.extend(items)    # result为包含所有图片url的列表

    # 根据图片url保存图片
    for i in range(len(result)):
        if result[i].endswith('jpg'):
            with open(photo_path + str(i) + '.jpg', 'wb') as f:
                photo = requests.get(result[i])
                f.write(photo.content)
