何时使用各种功能？
答案 0 :(得分：0)
请确保您尚未在某处终止会话。例如（在Python中）；
urllib3.exceptions.NewConnectionError: <urllib3.connection.HTTPConnection object at 0xsome_hex_address>: Failed to establish a new connection: [Errno 111] Connection refused第二个WebDriverWait将失败，并显示错误消息，因为始终执行“ try”的“ finally”子句，因此驱动程序退出/已关闭。因此，后续的WebDriverWait失败。容易错过。
顺便说一句，在上面的示例中，您可以将“ finally：”更改为“ except：”，将其更改为“ only”，如果尝试失败，请执行driver.quit（）。
