禁用Selenium Python中的图像 [英] Disable images in Selenium Python

问题描述

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

Because Webdriver waits for the entire page to load before going on to the next line, I think disabling images, css and javascript will speed things up.

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得到代码不希望加载图像和在Firefox上使用Python在Selenium WebDriver测试中使用Python渲染CSS

I got the code from stackoverflow Do not want images to load and CSS to render on Firefox in Selenium WebDriver tests with Python

但是当我添加

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

到结尾，它仍然加载图片：/

to the end, it still loads images :/

推荐答案

UPDATE ：答案可能不再有效，因为 permissions.default.image 已成为冻结设置，无法更改。请尝试使用 quickjava 扩展程序（链接到 answer ）。

UPDATE: The answer might not work any longer since permissions.default.image became a frozen setting and cannot be changed. Please try with quickjava extension (link to the answer).

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

You need to pass firefox_profile instance to the webdriver constructor:

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()

是如何显示的：
