python-3.x - Python Selenium：如何在 chrome 驱动程序中使用 debugger_address 选项进行远程调试？

Question

我想将我的 selenium chrome web 驱动程序启动到当前现有会话。

所以我试图通过远程调试进行连接，而不是启动一个新实例。

https://sites.google.com/a/chromium.org/chromedriver/help/operation-not-supported-when-using-remote-debugging

所以我所做的是通过 cmd 在 127.0.0.1:6813 启动 chrome。

C:\Program Files (x86)\Google\Chrome\Application>chrome.exe '127.0.0.1:6813'

启动了一个新的 chrome 实例。

现在在我的代码中，我使用 chrome 选项添加了 debugger_address="127.0.0.1:6813" 。

chrome_options.debugger_address="127.0.0.1:6813"

但是我的 Spyder IDE 给出了以下错误：

runfile('C:/Users/Gupta Niwas/Downloads/Programming/Projects/Mi/temp7.py', wdir='C:/Users/Gupta Niwas/Downloads/Programming/Projects/Mi')
Traceback (most recent call last):

我知道这个答案可能不再对您有用，但是对于那些仍然遭受此问题困扰的人，我找到了解决方案。首先，当您尝试创建 chrome 实例时，您还需要为该实例创建一个新的配置文件。这是一个命令：为了运行此命令，您必须将 chrome 添加到系统路径或转到安装 chrome 的目录，对于 Windows，通常是此路径：C:\Program Files (x86)\谷歌\Chrome\应用程序

chrome.exe -remote-debugging-port=9014 --user-data-dir="<AnyDirectoryOfYourChoice>"

现在你应该在这个实例中运行一个 chrome 实例，你可以打开任何你想要的东西，一旦你完成了，你可以使用下面的这个 python 代码来连接这个 chrome 实例。

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

chrome_options = Options()
chrome_options.add_experimental_option("debuggerAddress", "127.0.0.1:9014")
driver = webdriver.Chrome(options=chrome_options)

成功连接后，驱动程序将引用您的 chrome 实例，您可以像我们通常在 selenium 中一样进行控制。
