使用BeautifulSoup和Selenium刮取网站多个网页的内容

Question

我想废弃的网站是：

http://www.mouthshut.com/mobile-operators/Reliance-Jio-reviews-925812061

我想获取上述链接的最后一个页码以进行处理，在截取屏幕截图时为499.

我的代码：

   from bs4 import BeautifulSoup 
   from urllib.request import urlopen as uReq
   from selenium import webdriver;import time
   from selenium.webdriver.common.by import By
   from selenium.webdriver.support.ui import WebDriverWait
   from selenium.webdriver.support import expected_conditions as EC
   from selenium.webdriver.common.desired_capabilities import         DesiredCapabilities

   firefox_capabilities = DesiredCapabilities.FIREFOX
   firefox_capabilities['marionette'] = True
   firefox_capabilities['binary'] = '/etc/firefox'

   driver = webdriver.Firefox(capabilities=firefox_capabilities)
   url = "http://www.mouthshut.com/mobile-operators/Reliance-Jio-reviews-925812061"

   driver.get(url)
   wait = WebDriverWait(driver, 10)
   soup=BeautifulSoup(driver.page_source,"lxml")
   containers = soup.findAll("ul",{"class":"pages table"})
   containers[0] = soup.findAll("li")
   li_len = len(containers[0])
   for item in soup.find("ul",{"class":"pages table"}) : 
   li_text = item.select("li")[li_len].text
   print("li_text : {}\n".format(li_text))
   driver.quit()

我需要帮助才能找出代码中的错误以获取最后一个页码。此外，如果有人为此提供替代解决方案并提出实现我意图的方法，我将不胜感激。

如果您想获取上述链接的最后一个页码（ 499 Selenium ，您可以使用 Beautifulsoup 或 from selenium import webdriver driver = webdriver.Firefox(executable_path=r'C:\Utility\BrowserDrivers\geckodriver.exe') url = "http://www.mouthshut.com/mobile-operators/Reliance-Jio-reviews-925812061" driver.get(url) element = driver.find_element_by_xpath("//div[@class='row pagination']//p/span[contains(.,'Reviews on Reliance Jio')]") driver.execute_script("return arguments[0].scrollIntoView(true);", element) print(driver.find_element_by_xpath("//ul[@class='pagination table']/li/ul[@class='pages table']//li[last()]/a").get_attribute("innerHTML")) driver.quit() 如下：
