下載谷歌瀏覽器驅(qū)動(dòng)，并配置好

import timeimport randomfrom PIL import Imagefrom selenium import webdriverfrom selenium.webdriver.common.by import Byfrom selenium.webdriver.support.ui import WebDriverWaitfrom selenium.webdriver.support import expected_conditions as ECif __name__ == ’__main__’: options = webdriver.ChromeOptions() options.binary_location = r’C:UsershhhAppDataLocalGoogleChromeApplication谷歌瀏覽器.exe’ # driver=webdriver.Chrome(executable_path=r’D:360Chromechromedriverchromedriver.exe’) driver = webdriver.Chrome(options=options) #以java模塊為例 driver.get(’https://www.csdn.net/nav/java’) for i in range(1,20): driver.execute_script('window.scrollTo(0, document.body.scrollHeight)') time.sleep(2)二、獲取URL

from bs4 import BeautifulSoupfrom lxml import etree html = etree.HTML(driver.page_source)# soup = BeautifulSoup(html, ’lxml’)# soup_herf=soup.find_all('#feedlist_id > li:nth-child(1) > div > div > h2 > a')# soup_herftitle = html.xpath(’//*[@id='feedlist_id']/li/div/div/h2/a/@href’)

可以看到，一下爬取了很多，速度非常快

導(dǎo)入redis包后，配置redis端口和redis數(shù)據(jù)庫(kù)，用rpush函數(shù)寫入打開(kāi)redis

import redisr_link = redis.Redis(port=’6379’, host=’localhost’, decode_responses=True, db=1)for u in title: print('準(zhǔn)備寫入{}'.format(u)) r_link.rpush('csdn_url', u) print('{}寫入成功!'.format(u))print(’=’ * 30, ’n’, '共計(jì)寫入url：{}個(gè)'.format(len(title)), ’n’, ’=’ * 30)

大功告成！

在Redis Desktop Manager中可以看到，爬取和寫入都是非常的快。

要使用只需用rpop出棧就OK

one_url = r_link.rpop('csdn_url)')while one_url: print('{}被彈出！'.format(one_url))
