實例如下所示：

__author__ = 'Fred Zhao'

import requests

from bs4 import BeautifulSoup

import os

from urllib.request import urlretrieve

class Picture():

def __init__(self):

self.headers = {'User-Agent': 'Mozilla/5.0 (Macintosh; Intel Mac OS X 10_12_0) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/55.0.2883.95 Safari/537.36'}

self.base_url = 'https://list.jd.com/list.html?cat=9987,653,655&page='

self.base_path = os.path.dirname(__file__)

def makedir(self, name):

path = os.path.join(self.base_path, name)

isExist = os.path.exists(path)

if not isExist:

os.makedirs(path)

print("File has been created.")

else:

print('OK!The file is existed. You do not need create a new one.')

os.chdir(path)

def request(self, url):

r = requests.get(url, headers=self.headers)

return r

def get_img(self, page):

r = self.request(self.base_url + str(page))

plist = BeautifulSoup(r.text, 'lxml').find('div', id='plist')

item = plist.find_all('li', class_='gl-item')

print(len(item))

self.makedir('pictures')

num = 0

for i in item:

num += 1

imglist = i.find('div', class_='p-img')

print(num)

img = imglist.find('img')

print('This is %s picture' %num)

if img.get('src'):

url = 'https:' + img.get('src')

urlretrieve(url, filename=fileName)

if __name__ == '__main__':

picture = Picture()

for i in range(2): #控制爬取的頁數

picture.get_img(i+1)
