python-3.x - Web Scraping Linkedin 分页不适用于搜索

问题描述

当我尝试以下操作时，我无法让 Linkedin 分页：

搜索网址：https ://www.linkedin.com/search/results/people/?keywords=Business%20Development&origin=SWITCH_SEARCH_VERTICAL

然后我可以转到第一面，向下滚动（无限滚动），单击“下一步”，效果很好，但是在第 2 页上它不滚动。我已经意识到通过添加“＆page = 2”不会更新url，因此不会更新滚动变量。我找到了另一种方法来完成这项工作 - 我只是想知道我哪里出错了，有没有专业人士来修复这个脚本？

from selenium import webdriver
from bs4 import BeautifulSoup
from selenium.common.exceptions import NoSuchElementException
from time import sleep

userid = 'myemail@mail.com'
password = 'secret'

driver = webdriver.Chrome()

driver.get('https://www.linkedin.com')

driver.find_element_by_xpath("""//*[@id="login-email"]""").send_keys(userid)
driver.find_element_by_xpath("""//*[@id="login-password"]""").send_keys(password)
driver.find_element_by_xpath("""//*[@id="login-submit"]""").click()

driver.get('https://www.linkedin.com/search/results/people/?keywords=Business%20Development&origin=SWITCH_SEARCH_VERTICAL')

while True:

  SCROLL_PAUSE_TIME = 0.5

  # Get scroll height
  last_height = driver.execute_script("return document.body.scrollHeight")
  print('current url' + driver.current_url)

  while True:
      # Scroll down to bottom
      driver.execute_script("window.scrollTo(0, document.body.scrollHeight);")

      # Wait to load page
      sleep(SCROLL_PAUSE_TIME)

      # Calculate new scroll height and compare with last scroll height
      new_height = driver.execute_script("return document.body.scrollHeight")
      print('new height ' + str(new_height))
      if new_height == last_height:
          break
      last_height = new_height

  driver.find_element_by_xpath("""//button[@class='artdeco-pagination__button artdeco-pagination__button--next artdeco-button artdeco-button--muted artdeco-button--icon-right artdeco-button--1 artdeco-button--tertiary ember-view' and contains(.,'Next')]""").click()

解决方案

试试这样：

driver.execute_script("$('.artdeco-pagination__button--next').click()")

您不需要滚动。
