Python Selenium Webdriver 无法在无头模式下工作

Question

无法在无头模式下创建 Python Chrome WebDriver。

我使用的是 Chrome 版本 108.0.5359.94。

我还使用

Service(ChromeDriverManager().install())

自动安装兼容的 chromewebdriver。

注意：如果我下载适用的 chrome webdriver 并且不使用该服务，而是使用可执行文件路径，则会发生相同的结果。

重新创建此代码的代码非常简单。

from selenium import webdriver
from selenium.webdriver.chrome.options import Options
from selenium.webdriver.chrome.service import Service
from webdriver_manager.chrome import ChromeDriverManager

chrome_options = Options()
# chrome_options.add_argument('--headless')
chrome_options.add_argument('--remote-debugging-port=9222')
chrome_options.add_argument('--no-sandbox')
driver = webdriver.Chrome(service=Service(ChromeDriverManager().install()), options=chrome_options)
print(driver)

以常规（非无头）模式运行时，我得到了 webdriver 对象的预期打印：

python selenium_test.py 
<selenium.webdriver.chrome.webdriver.WebDriver (session="9b6ec32017d8d864f8e2061293faee40")>

但是当在无头模式下运行时（相同的代码只是从无头选项行中删除标记），我收到以下错误：

python selenium_test.py 
Traceback (most recent call last):

我希望无论我是否使用无头选项，都会创建 chrome 驱动程序。可能是什么原因造成的？

Answer 1

此处的问题在于您尝试设置用于调试的端口。
我尝试了你的代码，它对我也不起作用，但是当我将端口从

9222

更改为

61625

时，它起作用了。
所以，至少对我来说这有效：

from selenium import webdriver
from selenium.webdriver.chrome.service import Service
from selenium.webdriver.chrome.options import Options

options = Options()
options.headless = True
options.add_argument('--remote-debugging-port=61625')
options.add_argument('--no-sandbox')

webdriver_service = Service('C:\webdrivers\chromedriver.exe')
driver = webdriver.Chrome(service=webdriver_service, options=options)
print(driver)

输出是

<selenium.webdriver.chrome.webdriver.WebDriver (session="70ca99a865d0eb7b93a95f530ef1401b")>

您尝试过不同的方法吗？ 就像使用 WebDriverManager 创建驱动程序一样，请参阅下面的链接： https://pypi.org/project/webdriver-manager
