弃用警告：在 Windows 10 系统上通过 Selenium 使用 ChromeDriver 和 Chrome 使用选项而不是 chrome_options 错误

Question

尝试在我的 Windows 10 机器上运行此代码https://github.com/KalleHallden/reddit_automations/blame/master/movie-tickets.py

from selenium import webdriver
from selenium.webdriver.common.keys import Keys
from decouple import config
import time

# the way to locate the button or thing you want on a website in chrome is
# by pressing cmd + shift + c and then you can use your mouse to find the 
# info on the element that you want and you can copy the full xpath.

options = webdriver.ChromeOptions()
# options.add_argument('--ignore-certificate-errors')
# options.add_argument('--incognito')
# options.add_argument('--headless')
driver = webdriver.Chrome("/Users/kalle/Downloads/chromedriver83", chrome_options=options)
driver.get(config('THEATRE_SITE'))
# for some odd reason you need to reload the site for it to load.
# possibly a bug of the theatre site
driver.get(config('THEATRE_SITE'))
time.sleep(3)
# select city
button = driver.find_element_by_xpath('/html/body/div[1]/div[3]/div/div/div[1]/div/div[2]/ul/li[1]/label/input')
button.click()

# save city
button = driver.find_element_by_xpath('/html/body/div[1]/div[3]/div/div/div[2]/span/button')
button.click()
time.sleep(2)

# proceed to tickets tab
button = driver.find_element_by_xpath('/html/body/div[1]/nav/div[2]/div[2]/div[1]/ul[1]/li[1]/a')
button.click()
time.sleep(2)

# select the movie you want (should be more specific than just selecting the first one but whateva)
button = driver.find_element_by_xpath('/html/body/div[1]/main/div/div[2]/div/div/div/div[2]/div/div[2]/div[2]/div[2]/ul/li[1]/ul/li/div/div[1]/div/span[2]/a')
button.click()
time.sleep(1)

# select the time you want to go
button = driver.find_element_by_xpath('/html/body/div[1]/main/div/div[1]/div/div/div/div[4]/section/div/div[2]/div[2]/ul/li/ul/li[1]/div/span/span[3]/span[2]/span')
button.click()
time.sleep(1)

# choose amount of people
button = driver.find_element_by_xpath('/html/body/div[1]/main/div/div[2]/div/div/div/div/section/div/div[2]/div/button')
button.click()
time.sleep(2)

# choose seats
button = driver.find_element_by_xpath('/html/body/div[1]/main/div/div[1]/div/div/div/div[2]/section/div[3]/div[2]/button')
button.click()
time.sleep(2)

# pay
button = driver.find_element_by_xpath('/html/body/div[1]/main/div/div[1]/div/div/div/div[2]/section/div[4]/div/div[2]/button/span')
button.click()

我安装了所有正确的程序：

• 运行 python 3.8
• 安装了 chrome webdriver
• 运行版本 84 稳定版 chrome 网络浏览器

当我运行该程序时，它会打开 chrome，但是我得到一个空白网页，上面什么都没有，只有一些显示“数据：”的文本。仅此而已。

这是我在 VS 代码中得到的错误：

:\Users\user>python c:/chromedriver_win32/movie-tickets1.py
c:/chromedriver_win32/movie-tickets1.py:15: DeprecationWarning: use options instead of chrome_options
  driver = webdriver.Chrome(executable_path=r'C:\chromedriver_win32\chromedriver.exe', chrome_options=options)

    raise UndefinedValueError('{} not found. Declare it as envvar or define a default value.'.format(option))
decouple.UndefinedValueError: https://www.google.co.uk not found. Declare it as envvar or define a default value.

任何帮助将不胜感激，我不确定为什么解耦不起作用。

Answer 1

这个错误信息...

DeprecationWarning: use options instead of chrome_options

...暗示在您的程序中，您已用于chrome_options启动Selenium驱动的ChromeDriver启动的google-chrome Browsing Context。

chrome_options现在已弃用，您必须options改用并传递ChromeDriver的绝对路径和扩展程序。

解决方案

当您在windows-10系统上触发测试时，实际上您的代码行将是：

options = webdriver.ChromeOptions()
options.add_argument('--headless')
driver = webdriver.Chrome(executable_path=r'C:\chromedriver_win32\chromedriver.exe', options=options)

Answer 2

没关系！

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

chrome_options = Options()
chrome_options.add_argument('--headless')
browser = webdriver.Chrome(options=chrome_options)
