可以看见基本的全部信息:如(author、bookname、link.....)
写下代码如下:
python
import requests
from bs4 import BeautifulSoup
from lxml import etree
headers={'User-Agent':'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/123.0.0.0 Safari/537.36'}
link="https://www.dushu.com/"
r=requests.get(link,headers=headers)
r.encoding='utf-8'
soup=BeautifulSoup(r.text,'lxml')
house_list=soup.find_all('div',class_="border books-center")
html=etree.HTML(r.text)
# name=html.xpath('//div[@class="property-content-title"]/h3/text()')
# for house in house_list:
# name=soup.find('div',class_="nlist").a.strong.text()
#
# print(name)
name=html.xpath('//div[@class="bookname"]/a/text()')
author=html.xpath('//div[@class="bookauthor"]/text()')
# href=html.xpath('//div[@class="nlist"]/div/ul/li/a/@href')
#print(type(author))
for i,o in zip(name,author):
print('<<'+i+'>>',o)
运行结果:
接下来添加link链接:
可以看见现在网站设置了反爬,我们现在通过检查浏览器能正常爬取还是有反爬:
python
# 请用 python+selenium 爬取 XXX 网站上的所有a链接的 href属性并访问,输出访问地址和状态码
from selenium import webdriver
from selenium.webdriver.common.by import By
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC
import requests
driver = webdriver.Chrome()
# 这里以百度为例
driver.get("https://www.dushu.com/")
wait = WebDriverWait(driver, 10)
links = wait.until(EC.presence_of_all_elements_located((By.XPATH, "//a")))
# 遍历所有的链接元素,并输出href属性值
for link in links:
href = link.get_attribute("href")
if href.startswith("http"):
response = requests.get(href)
print(href, response.status_code)
else:
link.click()
print(driver.current_url, driver.execute_script('return document.readyState'),
requests.get(driver.current_url).status_code)
# 关闭浏览器
driver.quit()
运行结果:
现在可以看出是反爬。
