Question

我正在尝试使用两个不同的配置文件控制两个Google Chrome实例。但是，当我打开第一个配置文件，然后使用另一个配置文件运行第二个chrome实例时，会出现错误。

from selenium import webdriver


def launch(login, password):
    chrome_options = webdriver.ChromeOptions()
    chrome_options.add_argument(r'--user-data-dir=/home/marek/.config/google-chrome')
    chrome_options.add_argument(r'--profile-directory=Profile 3')
    second_options = webdriver.ChromeOptions()
    second_options.add_argument(r'--user-data-dir=/home/marek/.config/google-chrome')
    second_options.add_argument(r'--profile-directory=Profile 4')
    driver = webdriver.Chrome(options = chrome_options)
    second_driver = webdriver.Chrome(options = second_options)
    driver.get('http://google.com')
    second_driver.get('http://google.com')

if __name__ == '__main__':
    login = 'xxx'
    password = 'xxx'
    launch(login,password)

错误日志：

    raise exception_class(message, screen, stacktrace)
selenium.common.exceptions.WebDriverException: Message: unknown error: Chrome failed to start: exited abnormally
  (unknown error: DevToolsActivePort file doesn't exist)
  (The process started from chrome location /opt/google/chrome/google-chrome is no longer running, so ChromeDriver is assuming that Chrome has crashed.)

有什么想法可以使它正常工作吗？

Answer 1

Selenium Grid将通过并行运行测试来帮助您扩展规模。只需使用以下命令设置集线器和节点：

对于中心

java -jar selenium-server-standalone-3.14.0.jar -role hub

以及该节点

java -jar selenium-server-standalone-3.14.0.jar -role node  -hub http://localhost:4444/grid/register

Answer 2

Google在下面的文章中指出，您一次登录了多个Google帐户，但Google可能无法告知您登录的帐户。我认为解决方案是先注销一个帐户，然后再登录下一个帐户，或者使用某种方法将cookie保持在两个会话之间。 Google的这篇文章可能对您有帮助：

Answer 3

我相信您可以在不需要网格的情况下执行此操作。尝试将以下参数添加到ChromeOptions：

--disable-dev-shm-usage

Answer 4

这可能与您指定个人资料目录的方式有关。

以下代码对我有用（无论我是否登录，似乎都没有多大关系。）

指导：

即使不需要，我也包含了DesiredCapabilities（以防万一您想使用它）
替换为您的用户名！
根据需要替换
为2个浏览器指定n=2，为3个浏览器指定n=3，依此类推...
将创建用户个人资料Profile PyX，其中X= 1, 2, 3... etc.（取决于您同时启动的浏览器数量）
如果您在浏览器启动后向这些配置文件添加chrome扩展名，它们将在您下次运行代码时重新出现/自动加载...

from selenium import webdriver
from selenium.webdriver.chrome.options import DesiredCapabilities
'''if you remove this, do same for 'v_caps.append(DesiredCapabilities.Chrome.copy())' 
below'''
def launch(n):
    global v_drivers
    v_profiles = []; v_options = []; v_chromedrivers = []; v_caps = []
    #modify profile path and chromedrv as req/appropriately:
    profile_path = "C:/Users/<user>/AppData/Local/Google/Chrome/User Data/Profile Py"
    chromedrv_path = "C:/Users/<username>/<rest of path>/chromedriver.exe"
    for i in range(n):
        v_profiles.append(profile_path + str(i) + "/")
        v_options.append(webdriver.ChromeOptions())
        v_caps.append(DesiredCapabilities.CHROME.copy())
        v_chromedrivers.append(chromedrv_path)
        v_options[i].add_argument('--user-data-dir=' + v_profiles[i])
        #can remove as required - see note (a) above
        v_caps[i]["pageLoadStrategy"] = "eager"
        v_drivers.append(webdriver.Chrome(desired_capabilities= v_caps[i],
        executable_path=v_chromedrivers[i], options=v_options[i]))

        v_drivers[i].get('http://google.com')


v_drivers=[]
if __name__ == '__main__':
    n=2 #number of browsers you want to open
    launch(n)

如何同时使用Selenium Python控制两个Google Chrome配置文件？
