Python3多线程爬取meizitu的图片

python环境：python3

运行环境：win10和linux都可以，其他系统没测

1 安装依赖

pip install requests
pip install lxml
pip install feedparser

2 创建一个新文件夹

3 运行该脚本

python mzitu.py

源码如下：

# -*- coding: UTF-8 –*-
import feedparser
import requests
from lxml import etree
import threading
import random
import os
 
def get_url():
 
    rss_url = 'https://www.mzitu.com/feed/'
    feeds = feedparser.parse(rss_url)
 
    page_url = []
    for i in range(20):
        page_url.append(feeds.entries[i]['link'])
 
    return page_url
 
def download(dirname, imgurl):
 
    headers = {
    'referer':'https://www.mzitu.com/',
    'user-agent':'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/73.0.3683.86 Safari/537.36'
    }
 
    filename = imgurl.split('/')[-1]
 
    r = requests.get(imgurl, headers = headers, stream=True)
    if os.path.exists(dirname):
        with open(dirname + '/' + filename, 'wb') as f:
            for chunk in r.iter_content(chunk_size=32):
                f.write(chunk)
            print('下载:%s中' % filename)
    else:
        os.mkdir(dirname)
        with open(dirname + '/' + filename, 'wb') as f:
            for chunk in r.iter_content(chunk_size=32):
                f.write(chunk)
            print('下载:%s中' % filename)
 
def get_img(url):
 
    r = requests.get(url)
    page = etree.HTML(r.text)
    span = page.xpath('/html/body/div[2]/div[1]/div[4]/a[5]/span')
    hs = page.xpath('//h2[@class="main-title"]')
    for h in hs:
        title = h.text
    for a in span:
        pages = a.text
    try:
        for i in range(int(pages)+1):
            if i == 1:
                pass
            else:
                imgpage = url + '/' + str(i)
                r1 = requests.get(imgpage)
                page1 = etree.HTML(r1.text)
                x_href = page1.xpath('/html/body/div[2]/div[1]/div[3]/p/a/img')
                for href in x_href:
                    imgurl = href.get('src')
                    download(title, imgurl)
    except KeyboardInterrupt:
        pass
    except:
        pass
 
def main():
 
    urls = get_url()
    threads=[]
    for i in range(len(urls)):
        t = threading.Thread(target=get_img, args=(urls[0+i],))
        threads.append(t)
 
    for i in threads:
        i.start()

注意：经测试，4 升级版在运行时，会大量占用内存，内存小的电脑估计抗不住。。
