如何使用python

2024-05-07 • 问答

我有URL列表，我需要从中抓取数据。网站在新驱动程序中打开每个URL时拒绝连接，所以我决定在新选项卡中打开每个URL（该网站允许这种方式）。我正在使用的以下代码

from selenium import webdriver
import time
from lxml import html

driver = webdriver.Chrome()
driver.get('https://www.google.com/')

file = open('f:\\listofurls.txt','r')

for aa in file:
    aa = aa.strip()
    driver.execute_script("window.open('{}');".format(aa))
    soup = html.fromstring(driver.page_source)
    name = soup.xpath('//div[@class="name"]//text()')
    title = soup.xpath('//div[@class="title"]//text()')
    print(name,title)
    time.sleep(3)

但是问题是所有URL一次都打开，而不是一次打开。

您可以尝试以下代码：

from selenium import webdriver
from selenium.webdriver.common.keys import Keys
import time
from lxml import html

driver = webdriver.Chrome()
driver.get('https://www.google.com/')

file = open('f:\\listofurls.txt','r')

for aa in file:
    #open tab
    driver.find_element_by_tag_name('body').send_keys(Keys.COMMAND + 't') 
# You can use (Keys.CONTROL + 't') on other OSs

    # Load a page 
    driver.get(aa)
# Make the tests...
    soup = html.fromstring(driver.page_source)
    name = soup.xpath('//div[@class="name"]//text()')
    title = soup.xpath('//div[@class="title"]//text()')
    print(name,title)
    time.sleep(3)


driver.close()

我认为您必须像这样在循环之前删除：

driver = webdriver.Chrome()
driver.get('https://www.google.com/')

file = open('f:\\listofurls.txt','r')
aa = file.strip()

for i in aa:
    driver.execute_script("window.open('{}');".format(i))
    soup = html.fromstring(driver.page_source)
    name = soup.xpath('//div[@class="name"]//text()')
    title = soup.xpath('//div[@class="title"]//text()')
    print(name,title)
    time.sleep(3)
