Python爬取斗图啦网站

 首先我们简单的分析一下这个网站，我们需要爬取的就是图片，然后将图片网址爬取下来，下载

.

图片的下载地址就在这里然后我们开始吧

from  lxml import etree
import requests
from urllib import request
import re
import os
import threading
from queue import Queue

# 创建生产者类。目的是为了获取当前网页的图片地址

        }
        super(Procuder, self).__init__(*args, **kwargs)

        self.img_queue = img_queue

    def run(self):
        while True:

            self.parse_page(ulr)

            img_life = imgs_text + imgs_houzui
            self.img_queue.put((img,img_life))

# 创建消费者类，目的为了下载已经存储进img_queue队列的图片地址

            request.urlretrieve(img, "C:\\Users\\Administrator\\Desktop\\imgs\\" + img_life)
            print("%s下载成功" % img_life)

def main():
    # 创建需要存储ulr的队列
    page_queue = Queue(3391)
    img_queue = Queue(2000)
    for i in range(1, 3392):
        url = "https://www.doutula.com/photo/list/?page={}".format(i)
        page_queue.put(url)

        t.start()

    for h in range(30):

        t.start()
