生活这么无聊，保存点小姐姐的图片来点调料吧

1. 简介

使用的技术栈 ： python3, re, BeautifulSoup
目标网站： https://www.umei.net/p/gaoqing/cn/

免责声明：仅用于学习，请勿商用！！！！

2. 开始行动

2.1 步骤

1. 获取html
2. 数据清洗(获取图片标签)
3. 获取图片标签里面的src
4. 发起请求并保存图片

2.2 实现代码

import requests
import re
from bs4 import BeautifulSoup

url = 'https://www.umei.net/p/gaoqing/cn/'

r = requests.get(url)


# with open('./meinv.html','wb+') as f:
#     f.write(r.content)

if(r.status_code == 200 ):
    imgs = []
    soup = BeautifulSoup(r.content, 'html5lib')

    img_list = soup.select('.TypeBigPics img ')

    for i in img_list:
        # print(i)
        res = re.search('src="(.*?)"', str(i) , re.M | re.I)
        imgs.append( str (res.group(1)) )
    for i,k in enumerate (imgs):
        # print(i,type(k))
        ans = requests.get(k)
        if (ans.status_code == 200):
            with open(str (i) +'.jpg', 'wb+') as f:
                f.write(ans.content)

2.3 成果

2.4 成果分析

• 虽然成功拿到了图片，但是图片的清晰度不够，可进一步优化

2.5 优化

• 优化分析
  

通过分析可知：我们可以通过点击图片外面的a标签获取到图片大图

2.6 代码优化

import requests
import re
from bs4 import BeautifulSoup

url = 'https://www.umei.net/p/gaoqing/cn/'

r = requests.get(url)


# with open('./meinv.html','wb+') as f:
#     f.write(r.content)

if(r.status_code == 200 ):
    imgs = []
    soup = BeautifulSoup(r.content, 'html5lib')

    # 获取img外面的a标签
    aList = soup.select('.TypeBigPics')
    for item in aList:
        obj = re.search('.*?\/cn\/(.*?)".*', str(item), re.M | re.I )
        imgs.append( str( obj.group(1)) )

    ans_imgs = []
    for i,k in enumerate(imgs):
        # print(str(url + k))
        ans = requests.get(str(url+k))
        if(ans.status_code==200):
            soup1 = BeautifulSoup(ans.content, 'html5lib')
            imgBody = soup1.select('.ImageBody img')
            # print(imgBody)
            # 获取大图的src
            obj = re.search('.*?src="(.*?)"', str(imgBody), re.M | re.I )
            ans_imgs.append(  obj.group(1))

    # print(ans_imgs)
    # 保存大图
    for i,k in enumerate(ans_imgs):
        b = requests.get(str(k))
        if(b.status_code==200):
            with open('./'+str(i)+'.jpg','wb+') as f:
                f.write(b.content)
