javascript 在 Selenium Python 中禁用图像

Disable images in Selenium Python

提问by Hyman

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.

因为 Webdriver 在进入下一行之前会等待整个页面加载完毕，所以我认为禁用图像、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)

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

我从 stackoverflow 得到了代码不希望图像加载和 CSS 在 Firefox 上呈现在使用 Python 的 Selenium WebDriver 测试中

But when I add

但是当我添加

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

to the end, it still loads images :/

最后，它仍然加载图像：/

Unfortunately the option firefox_profile.set_preference('permissions.default.image', 2)will no longer work to disable images with the latest version of Firefox - [for reason see Alecxe's answer to my question Can't turn off images in Selenium / Firefox]

不幸的是，该选项firefox_profile.set_preference('permissions.default.image', 2)将不再适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]

The best solution i had was to use the firefox extension quickjava , which amongst other things can disable images- https://addons.mozilla.org/en-us/firefox/addon/quickjava/

我的最佳解决方案是使用 firefox 扩展程序 quickjava ，其中包括可以禁用图像 - https://addons.mozilla.org/en-us/firefox/addon/quickjava/

My Python code:

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)

Other things can also be switched off by adding the lines:

也可以通过添加以下行来关闭其他功能：

  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

UPDATE: The answer might not work any longer since permissions.default.imagebecame a frozen settingand cannot be changed. Please try with quickjavaextension (link to the answer).

更新：由于permissions.default.image成为冻结设置且无法更改，因此该答案可能不再有效。请尝试使用quickjava扩展名（链接到答案）。

You need to pass firefox_profileinstance to the webdriverconstructor:

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()

And this is how it would be displayed:

这就是它的显示方式：

The accepted answer doesn't work for me either. From the "reason" links referred by kyrenia I gathered that Firefox overrides the "permissions.default.image" preference on the first startup and I was able to prevent that by doing:

接受的答案对我也不起作用。从 kyrenia 引用的“原因”链接中，我发现 Firefox 在第一次启动时覆盖了“permissions.default.image”首选项，我能够通过执行以下操作来防止这种情况：

# Arbitrarily high number
profile.set_preference('browser.migration.version', 9001)

Which seems to be ok since I create the profile on each driver startup so there is nothing to actually be migrated.

这似乎没问题，因为我在每个驱动程序启动时创建了配置文件，因此实际上没有什么可迁移的。

I understand this is a pythonquestion, but it helped me with facebook/php-webdriver. (First result in search engine for php webdriver disable javascript)

我知道这是一个python问题，但它帮助我解决了facebook/php-webdriver。（搜索引擎中的第一个结果php webdriver disable javascript）

I thought I'd post my code (altered version of @kyrenia answer for php) to help others get up and running.

我想我会发布我的代码（@kyrenia php答案的修改版本）来帮助其他人启动和运行。
