方式二

方法：chrome的设置界面全是shadow-root，需要一层一层查早。

案例：enble flash

from selenium import webdriver
from selenium.webdriver.support.select import Select


options = Options()
chromedriver = "/usr/local/chromedriver/chromedriver"
options.add_experimental_option("excludeSwitches", ["enable-automation"])
options.add_argument("--user-data-dir=/home/chrome/.config/google-chrome/")
url = "chrome://settings/content/siteDetails?site=https%3A%2F%2Fwww.baidu.com%2F"
driver = webdriver.Chrome(chromedriver, options=options)

def expand_root_element(element):
    return driver.execute_script("return argument[0].shadowRoor", element)

def site_flash(url):
    driver.get(url)
    root1 = driver.find_element(By.TAG_NAME, "settings-ui")
    shadow_root1 = expand_root_element(root1)
    root2 = shadow_root1.find_element(By.ID, "container")
    root3 = root2.find_element(By.ID, "main")
    shadow_root3 = expand_root_element(root3)
    root4 = shadow_root3.find_element(By.CLASS_NAME, "showing-subpage")
    shadow_root4 = expand_root_element(root4)
    root5 = shadow_root4.find_element(By.ID, "advancedPage")
    root6 = root5.find_element(By.TAG_NAME, "settings-privacy-page")
    shadow_root6 = expand_root_element(root6)
    root7 = shadow_root6.find_element(By.ID, "pages")
    root8 = root7.find_element(By.TAG_NAME, "settings-subpage")
    root9 = root8.find_element(By.TAG_NAME, "site-details")
    shadow_root9 = expand_root_element(root9)
    root10 = shadow_root9.find_element(By.ID, "plugins")
    shadow_root10 = expand_root_element(root10)
    root11 = shadow_root10.find_element(By.ID, "permission")
    Select(root11).select_by_value("allow")
    driver.close()
    
site_flash(url)

注意：

　　1. 不能使用无界面模式。不能设置 handless 参数 。否则无法直接修改 Chrome 的设置

方式三

方法：使用键盘

案例：block 通知

from selenium import webdriver
from selenium.webdriver.common.keys import Keys
from selenium.webdriver.chrome.options import Options


options = Options()
chromedriver = "/usr/local/chromedriver/chromedriver"
options.add_experimental_option("excludeSwitches", ["enable-automation"])
options.add_argument("--user-data-dir=/home/chrome/.config/google-chrome/")
url = "chrome://settings/content/siteDetails?site=https%3A%2F%2Fwww.baidu.com%2F"
driver = webdriver.Chrome(chromedriver, options=options)

driver.get(url)
root1 = driver.find_element(By.TAG_NAME, "settings-ui")
for i in range(7):
    root1.send_keys(Keys.TAB)
root1.send_keys(Keys.ENTER)
root1.send_keys(Keys.DOWN)
root1.send_keys(Keys.ENTER)

注意：
