Python Selenium检测浏览器何时关闭

我建议使用:

>>> driver.get_log('driver')
[{'level': 'WARNING', 'message': 'Unable to evaluate script: disconnected: not connected to DevTools\n', 'timestamp': 1535095164185}]

因为每当用户关闭浏览器窗口时,驱动程序都会记录这一点,所以这似乎是最具python风格的解决方案。

所以你可以这样做:

DISCONNECTED_MSG = 'Unable to evaluate script: disconnected: not connected to DevTools\n'

while True:
    if driver.get_log('driver')[-1]['message'] == DISCONNECTED_MSG:
        print 'Browser window closed by user'
    time.sleep(1)

here .

我正在使用chromedriver 2.41和Chrome68。

与Federico Rubbis的回答类似,这对我很有用:

import selenium
from selenium import webdriver
browser = webdriver.Firefox()

# Now wait if someone closes the window
while True:
    try:
        _ = browser.window_handles
    except selenium.common.exceptions.InvalidSessionIdException as e:
        break
    time.sleep(1)

# ... Put code here to be executed when the window is closed

编辑:在不同环境中运行时甚至不稳定。丑陋的修正:使用 BaseException 而不是 selenium.common.exceptions.InvalidSessionIdException .
