Python Selenium : Extracting the PID of Chrome and Firefox browser

Question

如何获取Selenium启动的Chrome/Chromium或Firefox浏览器的进程ID(PID)？我正在寻找一种在 Selenium 网格中启动浏览器时也适用的解决方案。

Selenium Grid 无法使用 driver.service.process.pid。

Answer 1

检索Selenium启动的Chrome/Firefox浏览器的进程ID(PID)您可以使用以下解决方案:

火狐浏览器

• 代码块:

  from selenium import webdriver
  
  driver = webdriver.Firefox(executable_path=r'C:\WebDrivers\geckodriver.exe')
  my_dict = driver.capabilities
  print("PID of the browser process is: " + str(my_dict['moz:processID']))
  

• 控制台输出:

  PID of the browser process is: 2172
  

Chrome

• 代码块:

  from selenium import webdriver
  from contextlib import suppress
  import psutil
  
  driver = webdriver.Chrome(executable_path=r'C:\WebDrivers\chromedriver.exe')
  driver.get('https://www.google.com/')
  for process in psutil.process_iter():
    if process.name() == 'chrome.exe' and '--test-type=webdriver' in process.cmdline():
            with suppress(psutil.NoSuchProcess):
                print(process.pid)
  driver.quit()
  

• 控制台输出:

  12384
  13656
  13800
