Question

我想将Selenium chrome Web驱动程序启动到当前现有会话。

因此，我尝试通过远程调试进行连接，而不是启动新实例。

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

所以我所做的是由cmd在127.0.0.1:6813启动了chrome。

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

一个新的chrome实例开始了。

现在，在我的代码中，我使用了镶边选项添加了debugger_address =“ 127.0.0.1:6813”。

chrome_options.debugger_address="127.0.0.1:6813"

但是我的Spyder IDE出现以下错误：

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

我知道这个答案可能不再对您有用，但是对于仍然遭受此问题困扰的人，我已经找到了解决方案。首先，当您尝试创建chrome实例时，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，您将必须在系统路径中添加chrome或转到chrome的安装目录，对于Windows，通常是以下路径：C：\ Program Files（x86）\ Google \ Chrome \ Application

@Saga

现在，您应该在此实例中运行chrome实例，您可以打开所需的任何内容，一旦完成，就可以使用下面的python代码与此chrome实例进行连接。

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

连接成功后，驱动程序将引用您的chrome实例，您可以像通常在硒中那样进行控制。
