为什么我在尝试创建这个无尽的 selenium 循环时会出错？

Question

我正在使用以下 selenium 代码：

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

options=Options()

driver=webdriver.Chrome(options=options)

i = 0
while True:
    driver.get("https://www.google.com/")
    time.sleep(2)
    driver.quit()

    i = i + 1

想法是 chrome 浏览器在无限循环中打开和关闭。当我运行它时，我得到 'max retry error'。我该如何解决这个问题？

Answer 1

第一次执行 driver.quit() 时，它会终止浏览器实例。对于第二次迭代，必须执行的第一行将是 driver.get("https://www.google.com/")，现在由于驱动程序对象已在第一次迭代中被杀死，因此驱动程序在第二次迭代中为空。结果

sock.connect(sa)
ConnectionRefusedError: [WinError 10061] No connection could be made because the target machine actively refused it

During handling of the above exception, another exception occurred:

urllib3.exceptions.NewConnectionError: <urllib3.connection.HTTPConnection object at 0x000001D12A2671C0>: Failed to establish a new connection: [WinError 10061] No connection could be made because the target machine actively refused it

During handling of the above exception, another exception occurred:

raise MaxRetryError(_pool, url, error or ResponseError(cause))

要解决这个问题，

解决方案：您应该为每次迭代创建一个驱动程序实例。

i = 0
while True:
    driver = webdriver.Chrome(options=options)
    driver.get("https://www.google.com/")
    time.sleep(2)
    driver.quit()

    i = i + 1
