Webdriver的Edge如何无头模式

import time
from selenium import webdriver
from selenium.webdriver.edge.options import Options

options = Options()
options.add_argument("headless")

driver = webdriver.Edge(options=options)

driver.get('http://baidu.com')
driver.find_element_by_id('kw').send_keys('测试')
driver.find_element_by_id('su').click()

time.sleep(2)

# 只有截图才能看到效果咯
driver.save_screenshot('./ch.png')

driver.quit()
