python - 即使我使用了异常处理，Selenium webdriver Python 也会抛出 TimeoutException

问题描述

嗨，我正在测试的页面加载太慢，所以我从 stackoverflow 了解到我们可以为 driver.get() 设置超时

但是在尝试超时时，即使我使用了异常处理，我也会得到 TimeOutException

这是我的代码

from selenium import webdriver
import time
from selenium.common.exceptions import TimeoutException

driver = webdriver.Chrome()

t = time.time()
driver.set_page_load_timeout(20)

try:
    driver.get('https://www.slibuy.com/search?upcoming=store&update=all&uptime=all')
except TimeoutException as e:
    driver.execute_script("window.stop();")
    print("Exception has been thrown. " + str(e))

print('Time consuming:', time.time() - t)

这是错误消息

Traceback (most recent call last):
  File "main.py", line 33, in <module>
    driver.get('https://www.slibuy.com/search?upcoming=store&update=all&uptime=all')
  File "/home/noobie/anaconda3/lib/python3.6/site-packages/selenium/webdriver/remote/webdriver.py", line 332, in get
    self.execute(Command.GET, {'url': url})
  File "/home/noobie/anaconda3/lib/python3.6/site-packages/selenium/webdriver/remote/webdriver.py", line 320, in execute
    self.error_handler.check_response(response)
  File "/home/noobie/anaconda3/lib/python3.6/site-packages/selenium/webdriver/remote/errorhandler.py", line 242, in check_response
    raise exception_class(message, screen, stacktrace)
selenium.common.exceptions.TimeoutException: Message: timeout

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "main.py", line 35, in <module>
    driver.execute_script("window.stop();")
  File "/home/noobie/anaconda3/lib/python3.6/site-packages/selenium/webdriver/remote/webdriver.py", line 635, in execute_script
    'args': converted_args})['value']

有人可以解释什么是错的吗？
