python爬虫爬取图片(python抓取图片)

今天写了一个简化版爬美女图片，和之前的一样，用法：
输入你要搜索的套图的名字，然后会在d盘创建一个pic文件夹，下载的图片都在里面。下面给代码：

import requests
from lxml import etree
import re
import os

headers = {
    "User-Agent": "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/76.0.3809.132 Safari/537.36",
    "Referer": "https://www.mm131.net/"}

dic = {"0": "/xinggan/", "1": "/qingchun/", "2": "/xiaohua/", "3": "/chemo/", "4": "/qipao/",
       "5": "/mingxing/"}


number=input("请输入您的套图序号:")
number=int(number)
print("0:xinggan,1:qingchun,2:xiaohua,3:chemo,4:qipao,5:mingxing")
name=input("n"+"请输入目标在哪个套图范围")


url="https://www.mm131.net/{}/{}.html".format(dic[name],number)

response=requests.get(url=url,headers=headers,allow_redirects=False)
response.encoding=response.apparent_encoding
res = response.text  # 解析完成的网页
html = etree.HTML(res)


pages = html.xpath("//span[@class='page-ch'][1]/text()")
#print(url)
print(pages)
pages_number=re.findall(r"d+",str(pages))

biggest=''.join(str(pages_number[-1]))
biggest=int(biggest)#统计套图一共有多少页
print(biggest)
try:

    os.chdir("D://")
    os.mkdir("pic")
    os.chdir("D://pic/")

except:
    pass

print(os.getcwd())
for i in range(1,biggest+1):
    url_picture = "https://img1.mmmw.net/pic/{}/{}.jpg".format(number, i)
    picture=requests.get(url=url_picture,headers=headers,allow_redirects=False)
    with open("D://pic/" + "第" + str(number)+"("+str(i)+")" + "张" + ".jpg", "ab+") as f:
        print("开始下载第" + str(i) + "张")
        f.write(picture.content)
print("结束")
