python实战项目：爬取某网帅哥图片

前言

我也不知道说啥了， 看呗，就当是一个案例练习吧，

首先导入库

from bs4 import BeautifulSoup
from urllib.request import urlretrieve
import requests
import os
import time

主体代码（一）

if __name__ == '__main__':
    list_url = []
    for num in range(1,3):
        if num == 1:
            url = 'http://www.shuaia.net/index.html'
        else:
            url = 'http://www.shuaia.net/index_%d.html' % num
        headers = {
                "User-Agent":"Mozilla/5.0 (Windows NT 6.1; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/58.0.3029.110 Safari/537.36"
        }
        req = requests.get(url = url,headers = headers)
        req.encoding = 'utf-8'
        html = req.text
        bf = BeautifulSoup(html, 'lxml')
        targets_url = bf.find_all(class_='item-img')
        
        for each in targets_url:
            list_url.append(each.img.get('alt') + '=' + each.get('href'))

    print('连接采集完成')

主体代码（二）

for each_img in list_url:
        img_info = each_img.split('=')
        target_url = img_info[1]
        filename = img_info[0] + '.jpg'
        print('下载：' + filename)
        headers = {
            "User-Agent":"Mozilla/5.0 (Windows NT 6.1; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/58.0.3029.110 Safari/537.36"
        }
        img_req = requests.get(url = target_url,headers = headers)
        img_req.encoding = 'utf-8'
        img_html = img_req.text
        img_bf_1 = BeautifulSoup(img_html, 'lxml')
        img_url = img_bf_1.find_all('div', class_='wr-single-content-list')
        img_bf_2 = BeautifulSoup(str(img_url), 'lxml')
        img_url = 'http://www.shuaia.net' + img_bf_2.div.img.get('src')
        if 'images' not in os.listdir():
            os.makedirs('images')
        urlretrieve(url = img_url,filename = 'images/' + filename)
        time.sleep(1)

    print('下载完成！')

感觉如何？自己能实现吗？欢迎大家交流学习
