在Selenium Python中禁用图像

Question

因为Webdriver在进入下一行之前等待整个页面加载,我认为禁用图像,css和javascript会加快速度.

from selenium import webdriver
from selenium.webdriver.firefox.firefox_profile import FirefoxProfile

def disableImages(self):
    ## get the Firefox profile object
    firefoxProfile = FirefoxProfile()
    ## Disable CSS
    firefoxProfile.set_preference('permissions.default.stylesheet', 2)
    ## Disable images
    firefoxProfile.set_preference('permissions.default.image', 2)
    ## Disable Flash
    firefoxProfile.set_preference('dom.ipc.plugins.enabled.libflashplayer.so',
                                      'false')
    ## Set the modified profile while creating the browser object 
    self.browserHandle = webdriver.Firefox(firefoxProfile)

我从stackoverflow获取代码不希望加载图像和使用Python在Selenium WebDriver测试中在Firefox上渲染CSS

但是当我补充说

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

到最后,它仍然加载图像:/

不幸的是,该选项firefox_profile.set_preference('permissions.default.image', 2)将不再用于使用最新版本的Firefox禁用图像 - [原因请参阅Alecxe对我的问题的回答无法关闭Selenium/Firefox中的图像 ]

我最好的解决方案是使用firefox扩展quickjava,其中包括禁用图像 - https://addons.mozilla.org/en-us/firefox/addon/quickjava/

我的Python代码:

 from selenium import webdriver
 firefox_profile = webdriver.FirefoxProfile()

 firefox_profile.add_extension(folder_xpi_file_saved_in + "\\quickjava-2.0.6-fx.xpi")
 firefox_profile.set_preference("thatoneguydotnet.QuickJava.curVersion", "2.0.6.1") ## Prevents loading the 'thank you for installing screen'
 firefox_profile.set_preference("thatoneguydotnet.QuickJava.startupStatus.Images", 2)  ## Turns images off
 firefox_profile.set_preference("thatoneguydotnet.QuickJava.startupStatus.AnimatedImage", 2)  ## Turns animated images off

 driver = webdriver.Firefox(firefox_profile)
 driver.get(web_address_desired)

其他东西也可以通过添加行来关闭:

  firefox_profile.set_preference("thatoneguydotnet.QuickJava.startupStatus.CSS", 2)  ## CSS
  firefox_profile.set_preference("thatoneguydotnet.QuickJava.startupStatus.Cookies", 2)  ## Cookies
  firefox_profile.set_preference("thatoneguydotnet.QuickJava.startupStatus.Flash", 2)  ## Flash
  firefox_profile.set_preference("thatoneguydotnet.QuickJava.startupStatus.Java", 2)  ## Java
  firefox_profile.set_preference("thatoneguydotnet.QuickJava.startupStatus.JavaScript", 2)  ## JavaScript
  firefox_profile.set_preference("thatoneguydotnet.QuickJava.startupStatus.Silverlight", 2)  ## Silverlight

Answer 2

更新:答案可能不再有效,因为permissions.default.image成为冻结设置,无法更改.请尝试quickjava扩展(链接到答案).

您需要将firefox_profile实例传递给webdriver构造函数:

from selenium import webdriver

firefox_profile = webdriver.FirefoxProfile()
firefox_profile.set_preference('permissions.default.stylesheet', 2)
firefox_profile.set_preference('permissions.default.image', 2)
firefox_profile.set_preference('dom.ipc.plugins.enabled.libflashplayer.so', 'false')

driver = webdriver.Firefox(firefox_profile=firefox_profile)
driver.get('http://www.stackoverflow.com/')

driver.close()

这就是它的显示方式:
