在新标签中打开网页 Selenium + Python[英] Open web in new tab Selenium + Python

问题描述

所以我试图在我的 WebDriver 内的新标签页上打开网站.我想这样做,因为使用 PhantomJS 为每个网站打开一个新的 WebDriver 大约需要 3.5 秒,我想要更快的速度...

我正在使用一个多进程的python脚本,我想从每个页面中获取一些元素,所以工作流程是这样的:

Open Browser

Loop throught my array
For element in array -> Open website in new tab -> do my business -> close it

但我找不到任何方法来实现这一点.

这是我正在使用的代码.网站之间需要很长时间,我需要它快速......允许使用其他工具,但我不知道有太多工具可以用于废弃使用 JavaScript 加载的网站内容(在加载时触发某些事件时创建的 div 等)为什么我需要 Selenium... BeautifulSoup 不能用于我的某些页面.

推荐答案

可以通过COMMAND + T命令 + W (OSX).在其他操作系统上,您可以使用 CONTROL + T/CONTROL + W.

selenium 中,您可以模拟这种行为.您将需要创建一个 Web 驱动程序和您需要的测试尽可能多的选项卡.

这是代码.

from selenium import webdriver
from selenium.webdriver.common.keys import Keys

driver = webdriver.Firefox()
driver.get("http://www.google.com/")

#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('http://stackoverflow.com/')
# Make the tests...

# close the tab
# (Keys.CONTROL + 'w') on other OSs.
driver.find_element_by_tag_name('body').send_keys(Keys.COMMAND + 'w') 


driver.close()
