刷新网页

Question

我试图使一个函数，刷新任何网页时，给定的网址。但程序无法运行。我做错什么了？这是我的密码：

from selenium import webdriver
import time

def page_refresh(url):
    driver = webdriver.Firefox()
    driver.get(url)
    x = 0
    while x <= 5:
        time.localtime(10)
        driver.refresh(url)
    driver.close

page_refresh('https://www.wikipedia.org/')

这就是我得到的：

Traceback (most recent call last):
File "C:\Users\100453649\PycharmProjects\AutoRefresher\venv\lib\site-packages\selenium\webdriver\common\service.py", line 76, in start

During handling of the above exception, another exception occurred:

Answer 1

你的例外清楚地表明

selenium.common.exceptions.WebDriverException: Message: 'geckodriver' executable needs to be in PATH.

解决方案：

添加gecko驱动程序路径：

示例：

 from selenium import webdriver
 driver = webdriver.Firefox(executable_path=r'your\path\geckodriver.exe')
 driver.get(url)
