Question

from selenium import webdriver

driver = webdriver.Chrome()
driver.set_page_load_timeout(7)

def urlOpen(url):
    try:
        driver.get(url)
        print(driver.current_url)
    except:
        driver.delete_all_cookies()
        print("Failed")
        return

urls = ['http://motahari.ir/', 'https://facebook.com', 'https://google.com']

for url in urls:
    urlOpen(url)

实际上，这个问题是Python Selenium. How to use driver.set_page_load_timeout() properly?。

上面修改后的代码通常运行得很好，但奇怪的是，大约10次delete_all_cookies()中有2次抛出timeoutException。我尝试在try-catch之前添加另一个time.sleep块，隐式/显式等待或delete_all_cookies()，但都无效。

我不知道为什么以及如何delete_all_cookies()抛出timeoutException ...有什么方法可以阻止它吗？

Traceback (most recent call last):
  File "C:/urlOpen.py", line 19, in <module>

  File "C:/urlOpen.py", line 12, in urlOpen

有时，我得到

为什么delete_all_cookies（）有时会抛出timeoutException？
