selenium4 无法连接到本地主机上的 chrome

Question

我要疯了，试图在 Selenium4 中连接到本地主机上的 Chrome 实例。 我使用 bash 调用了 chrome

$ /Applications/Google\ Chrome.app/Contents/MacOS/Google\ Chrome --remote-debugging-port=6666 --user-data-dir=/Users/h/Desktop/MY/chrome-profile

接下来我尝试从 Selenium4 连接

from selenium import webdriver
from selenium.webdriver.common.by import By
from selenium.webdriver.chrome.options import Options
from selenium.webdriver.chrome.service import Service as ChromeService
from webdriver_manager.chrome import ChromeDriverManager



# opt = Options()
# opt.add_experimental_option("debuggerAddress", "localhost:6666")

# opt.add_argument("debuggerAddress", "localhost:6666") 
# opt.add_debuggerAddress("localhost:6666") 
# opt.add_debugger_address("localhost:6666") 
# web_driver = webdriver.Chrome(options=opt)


# chrome_options = Options()
# chrome_options.add_experimental_option("debuggerAddress", "localhost:6666")

# driver = webdriver.Chrome(chrome_options=chrome_options)
# driver.get('https://www.google.com')


path = '/Users/h/Desktop/MY/webdrivers/chrome/105.0.5195.52/chromedriver'

# driver = webdriver.Chrome(service=Service(ChromeDriverManager().install()), options=opt)

# service = Service(executable_path=ChromeDriverManager().install())
# driver = webdriver.Chrome(service=service, options=chrome_options)
# driver.get('https://www.example.com/')

service = ChromeService(executable_path=path, port=6666) # i tried with local path and ChromeDriverManager
driver = webdriver.Chrome(service=service)
driver.get('https://www.example.com/')

我想我尝试了所有可能的选择：

• 将 http:// 添加到 localhost 会引发错误，
• 使用 chrome_options=chrome_options 会引发弃用警告，指出我应该使用 >options=<，并且似乎对 localhost 中的浏览器没有影响，
• 尝试从本地文件启动 webdriver，目前建议使用 ChromeDriverManager。 两者都有效。 直到我想指定选项。

我还浏览了我在大约 20 个网站上找到的示例，包括。 github 错误报告 - 人们声称他们的代码在 VSCode 升级之前可以正常工作。

我想我的问题是 - 我尝试传递 chrome 选项的方式有什么问题，还是我真的遇到了错误？

====== 编辑：这是一个完整的错误跟踪：

Answer 1

好吧，您没有导入 webdriver，并且您已将 Service 命名为 ChromeService。

 from selenium.webdriver.common.by import By
 from selenium.webdriver.chrome.options import Options
 from selenium.webdriver.chrome.service import Service as ChromeService
 from selenium import webdriver

然后避免通过Options传递端口并使用Service的选项端口（现在称为ChromeServie）

# chrome_options = Options()
# chrome_options.add_experimental_option("debuggerAddress", "localhost:6666")
service = ChromeService(executable_path="chromedriver", port=6666) #at this line you can use your ChromeDriverManager
driver = webdriver.Chrome(service=service)
driver.get('https://www.example.com/')

我终于想通了，尽管我不得不说这比知道如何更幸运。 文档非常缺乏:(

如果有人正在寻找如何控制已经运行的浏览器，特别是使用 selenium4 和 python，这里是：

from selenium import webdriver
from webdriver_manager.chrome import ChromeDriverManager

chrome_options = webdriver.ChromeOptions()
chrome_options.add_experimental_option("debuggerAddress", "localhost:6666")
driver = webdriver.Chrome(executable_path=ChromeDriverManager().install(), chrome_options = chrome_options)

driver.get('http://example.com')
