因为从孩子那里劫持会话的方法似乎不再起作用，你不得不使用psutils手动终止Chrome和WebDriver及其所有子项，直到他们将会话劫持添加到Web驱动程序中。

import time
import multiprocessing
from selenium import webdriver
import psutil

def start_thread(url):
    driver = webdriver.Chrome()
    driver.get(url)
    time.sleep(30)

def get_all_children(proc: psutil.Process):
    try:
        if len(proc.children()) == 0:
            return []
        else:
            returned_list = []
            for item in proc.children():
                returned_list.append(item)
                returned_list.extend(get_all_children(item))
            return returned_list
    except psutil.NoSuchProcess:
        return []

if __name__ == "__main__":
    urls = ['http://www.python.org','http://www.python.org']
    threads = []
    for counter in range(len(urls)):
        thread = multiprocessing.Process(target=start_thread, name=f'start_thread_{counter}', args=(urls[counter],))
        threads.append(thread)
        thread.start()

    time.sleep(5)
    for t in threads:
        children = get_all_children(psutil.Process(pid=t.pid))
        t.terminate()
        for child in children:
            try:
                child.terminate()
            except psutil.NoSuchProcess:
                pass  # in case child was already dead

        time.sleep(5)  # to see what's happening

以这种方式搜索孩子在某种程度上是必要的，因为Chrome往往会打开很多孩子，尽管它可能仅限于Windows上的两个孩子，但其他系统可能不是这样。
