如何使用python在Selenium中以编程方式使Firefox无头?

我正在使用python,selenium和firefox运行此代码,但仍获得firefox的“ head”版本: binary = FirefoxBinary('C:\\Program Files (x86)\\Mozilla Firefox\\firefox.exe', log_file=sys.stdout) binary.add_command_line_options('-headless') self.driver = webdriver.Firefox(firefox_binary=binary) 我还尝试了一些二进制的变体: binary = FirefoxBinary('C:\\Program Files\\Nightly\\firefox.exe', log_file=sys.stdout) binary.add_command_line_options("--headless")

binary = FirefoxBinary('C:\\Program Files\\Nightly\\firefox.exe', log_file=sys.stdout)
        binary.add_command_line_options("--headless")

I am running this code with python, selenium, and firefox but still get 'head' version of firefox:

binary = FirefoxBinary('C:\\Program Files (x86)\\Mozilla Firefox\\firefox.exe', log_file=sys.stdout)
binary.add_command_line_options('-headless')
self.driver = webdriver.Firefox(firefox_binary=binary)

I also tried some variations of binary:

binary = FirefoxBinary('C:\\Program Files\\Nightly\\firefox.exe', log_file=sys.stdout)
        binary.add_command_line_options("--headless")

要不费吹灰之力地调用Firefox浏览器,可以headless通过以下Options()类设置属性:

from selenium import webdriver
from selenium.webdriver.firefox.options import Options

options = Options()
options.headless = True
driver = webdriver.Firefox(options=options, executable_path=r'C:\Utility\BrowserDrivers\geckodriver.exe')
driver.get("http://google.com/")
print ("Headless Firefox Initialized")
driver.quit()

还有另一种方法可以完成无头模式。如果你需要禁用或启用Firefox中的无头模式,而无需修改代码,您可以设置环境变量MOZ_HEADLESS,以什么,如果你想Firefox的运行无头,或根本不设置它。

例如,在使用持续集成并且希望在服务器中运行功能测试但仍能够在PC上以正常模式运行测试时,此功能非常有用。

$ MOZ_HEADLESS=1 python manage.py test # testing example in Django with headless Firefox

要么

$ export MOZ_HEADLESS=1   # this way you only have to set it once
$ python manage.py test functional/tests/directory
$ unset MOZ_HEADLESS      # if you want to disable headless mode

如何配置ChromeDriver通过Selenium以无头模式启动Chrome浏览器?

To invoke Firefox Browser headlessly, you can set the headless property through Options() class as follows:

from selenium import webdriver
from selenium.webdriver.firefox.options import Options

options = Options()
options.headless = True
driver = webdriver.Firefox(options=options, executable_path=r'C:\Utility\BrowserDrivers\geckodriver.exe')
driver.get("http://google.com/")
print ("Headless Firefox Initialized")
driver.quit()

There's another way to accomplish headless mode. If you need to disable or enable the headless mode in Firefox, without changing the code, you can set the environment variable MOZ_HEADLESS to whatever if you want Firefox to run headless, or don't set it at all.

This is very useful when you are using for example continuous integration and you want to run the functional tests in the server but still be able to run the tests in normal mode in your PC.

$ MOZ_HEADLESS=1 python manage.py test # testing example in Django with headless Firefox

or

$ export MOZ_HEADLESS=1   # this way you only have to set it once
$ python manage.py test functional/tests/directory
$ unset MOZ_HEADLESS      # if you want to disable headless mode

第一个答案不再起作用。

这对我有用:

from selenium.webdriver.firefox.options import Options as FirefoxOptions
from selenium import webdriver

options = FirefoxOptions()
options.add_argument("--headless")
driver = webdriver.Firefox(options=options)
driver.get("http://google.com")

The first answer does't work anymore.

This worked for me:

from selenium.webdriver.firefox.options import Options as FirefoxOptions
from selenium import webdriver

options = FirefoxOptions()
options.add_argument("--headless")
driver = webdriver.Firefox(options=options)
driver.get("http://google.com")

我的答案:

set_headless(headless=True) is deprecated. 

https://seleniumhq.github.io/selenium/docs/api/py/webdriver_firefox/selenium.webdriver.firefox.options.html

options.headless = True

为我工作

My answer:

set_headless(headless=True) is deprecated. 

https://seleniumhq.github.io/selenium/docs/api/py/webdriver_firefox/selenium.webdriver.firefox.options.html

options.headless = True

works for me

只是为以后可能会发现此问题的人提供的注释(并希望使用java的方法来实现此目的);FirefoxOptions还能够启用无头模式:

FirefoxOptions firefoxOptions = new FirefoxOptions();
firefoxOptions.setHeadless(true);

Just a note for people who may have found this later (and want java way of achieving this); FirefoxOptions is also capable of enabling the headless mode:

FirefoxOptions firefoxOptions = new FirefoxOptions();
firefoxOptions.setHeadless(true);

Used below code to set driver type based on need of Headless / Head for both Firefox and chrome:

// Can pass browser type 

if brower.lower() == 'chrome':
    driver = webdriver.Chrome('..\drivers\chromedriver')
elif brower.lower() == 'headless chrome':
    ch_Options = Options()
    ch_Options.add_argument('--headless')
    ch_Options.add_argument("--disable-gpu")
    driver = webdriver.Chrome('..\drivers\chromedriver',options=ch_Options)
elif brower.lower() == 'firefox':
    driver = webdriver.Firefox(executable_path=r'..\drivers\geckodriver.exe')
elif brower.lower() == 'headless firefox':
    ff_option = FFOption()
    ff_option.add_argument('--headless')
    ff_option.add_argument("--disable-gpu")
    driver = webdriver.Firefox(executable_path=r'..\drivers\geckodriver.exe', options=ff_option)
elif brower.lower() == 'ie':
    driver = webdriver.Ie('..\drivers\IEDriverServer')
else:
    raise Exception('Invalid Browser Type')
