这里是第一页的爬虫如果想爬第几页就换url如果想全部爬下来的话，for循环就ok
以下是代码：
[Python] 纯文本查看 复制代码 from bs4 import BeautifulSoup
import requests
import os
headers = {
'User-Agent': "Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.1 (KHTML, like Gecko) Chrome/22.0.1207.1 Safari/537.1",
'Accept': "text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,*/*;q=0.8",
'Accept-Encoding': 'gzip',
"Referer": "https://www.mzitu.com/101553"
} #头部文件
path="jpg" #jpg为保存目录，可随意更改
os.chdir(path)
url = 'https://www.mzitu.com'
response1 = requests.get(url, headers=headers)
html_soup1 = BeautifulSoup(response1.text, 'lxml')
all_url=html_soup1.find("ul",{"id":"pins"}).find_all("a")
count=1
for href in all_url:
count=count+1
if count%2!=0:
href1=href['href']
#print(href1)
for href2 in href:
response2 = requests.get(href1, headers=headers)
html_Soup2 = BeautifulSoup(response2.text, 'lxml')
pic_address= html_Soup2.find("div",{"class":"main-image"}).find("img")['src']
#print(pic_address)
next_address=html_Soup2.find_all("span")[9]
max_adress=next_address.get_text()
name = html_Soup2.find("div", {"class": "main-image"}).find("img")['alt']
os.mkdir(name)
os.chdir(name)
for i in range (1,int(max_adress)+1):
#print(i)
next_url = href1+'/'+str(i)
response3 = requests.get(next_url, headers=headers)
html_Soup3 = BeautifulSoup(response3.text, 'lxml')
pic_address2 = html_Soup3.find("div", {"class": "main-image"}).find("img")['src']
title = html_Soup3.find("h2")
name1 = title.get_text()
img = requests.get(pic_address2, headers=headers)
f = open(name1 + '.jpg', 'ab')
f.write(img.content)
f.close()
os.chdir("/Users/w2ng/untitled/venv/jpg")#获取自己的工作目录，将/Users/w2ng/untitled/venv 改为os.getcwd()的结果就ok
