一、需求：

基于Bing网站，输入关键词，批量下载图片保存到本地

二、演示：

三、直接上代码

import os
import urllib.request
import urllib.parse
from bs4 import BeautifulSoup
import re
import time

# 设置请求头
header = {
    'User-Agent': 'Mozilla/5.0 (Windows NT 10.0; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/50.0.2661.102 UBrowser/6.1.2107.204 Safari/537.36'
}

# 网址信息
url = "https://cn.bing.com/images/async?q={0}&first={1}&count={2}&scenario=ImageBasicHover&datsrc=N_I&layout=ColumnBased&mmasync=1&dgState=c*9_y*2226s2180s2072s2043s2292s2295s2079s2203s2094_i*71_w*198&IG=0D6AD6CBAF43430EA716510A4754C951&SFX={3}&iid=images.5599"

# 需要爬取的图片关键词
name = "深咖网瓷砖"

# 本地存储路径
path = "D:\\" + name

def getStartHtml(url, key, first, loadNum, sfx):
    """获取缩略图列表页"""
    page = urllib.request.Request(url.format(key, first, loadNum, sfx),
                                  headers=header)
    html = urllib.request.urlopen(page)
    return html

def findImgUrlFromHtml(html, rule, count):
    """从缩略图列表页中找到原图的url，并返回这一页的图片数量"""
    soup = BeautifulSoup(html, "lxml")
    link_list = soup.find_all("a", class_="iusc")
    for link in link_list:
        result = re.search(rule, str(link))
        if result:
            # 将字符串"amp;"删除
            url = result.group(0)
            # 组装完整url
            url = url[8:len(url)]
            # 打开高清图片网址
            getImage(url, count)
            count += 1
        else:
            continue
    # 完成一页，继续加载下一页
    return count

def getImage(url, count):
    """从原图url中将原图保存到本地"""
    try:
        time.sleep(0.5)
        urllib.request.urlretrieve(url, path + '\\' + str(count + 1) + '.jpg')
    except Exception:
        time.sleep(1)
        print("产生了一点点错误，跳过...")
    else:
        print("图片+1,成功保存 " + str(count + 1) + " 张图")

def main():
    key = urllib.parse.quote(name)
    first = 1
    loadNum = 35
    sfx = 1
    count = 0

    # 正则表达式
    rule = re.compile(r"\"murl\"\:\"http\S[^\"]+")

    # 图片保存路径
    if not os.path.exists(path):
        os.makedirs(path)

    # 最多抓500张
    while count < 500:
        html = getStartHtml(url, key, first, loadNum, sfx)
        count += findImgUrlFromHtml(html, rule, count)
        first = count + 1
        sfx += 1

if __name__ == '__main__':
    main()

四、结果
