如果是不創建新瀏覽器窗口，直接在已打開的瀏覽器，則代碼需要修改爲：
caps = DesiredCapabilities.CHROME
caps['loggingPrefs'] = {'performance': 'ALL'}
options = webdriver.ChromeOptions()
options.add_experimental_option('w3c', False)
options.add_experimental_option("debuggerAddress", "127.0.0.1:9527")
driver = webdriver.Chrome(options=options, desired_capabilities=caps)
