如何使用 selenium 重新连接到 webdriver 打开的浏览器? [英] How can I reconnect to the browser opened by webdriver with selenium?
问题描述
由于某些未知原因，我的浏览器打开远程服务器的测试页面非常缓慢.所以我在想是否可以在退出脚本后重新连接到浏览器但不执行 webdriver.quit() 这将使浏览器保持打开状态.它可能是一种 HOOK 或 webdriver 句柄.我已经查找了 selenium API 文档，但没有找到任何函数.我使用的是 Chrome 62、x64、windows 7、selenium 3.8.0.无论问题能否得到解决，我将不胜感激.
For some unknown reasons ,my browser open test pages of my remote server very slowly. So I am thinking if I can reconnect to the browser after quitting the script but don't execute webdriver.quit() this will leave the browser opened. It is probably kind of HOOK or webdriver handle.
I have looked up the selenium API doc but didn't find any function.
I'm using Chrome 62,x64,windows 7,selenium 3.8.0.
I'll be very appreciated whether the question can be solved or not.
推荐答案
否，退出脚本后将无法重新连接到之前的Web 浏览会话.即使您能够从之前的浏览上下文中提取Session ID、Cookies和其他会话属性，您仍然无法将这些属性作为 HOOK 传递给 WebDriver.
No, you can't reconnect to the previous Web Browsing Session after you quit the script. Even if you are able to extract the Session ID, Cookies and other session attributes from the previous Browsing Context still you won't be able to pass those attributes as a HOOK to the WebDriver.
更简洁的方法是调用 webdriver.quit() 然后跨越一个新的浏览上下文.
A cleaner way would be to call webdriver.quit() and then span a new Browsing Context.
围绕将 WebDriver 重新连接到现有的 浏览上下文 进行了大量讨论和尝试.在讨论中允许网络驱动程序附加到正在运行的浏览器 Simon Stewart [Creator WebDriver] 明确提到:
There had been a lot of discussions and attempts around to reconnect WebDriver to an existing running Browsing Context. In the discussion Allow webdriver to attach to a running browser Simon Stewart [Creator WebDriver] clearly mentioned:
- 重新连接到现有的浏览上下文是浏览器特定的功能，因此不能以通用方式实现.
- 使用 internet-explorer，可以遍历操作系统中打开的窗口并找到要附加到的正确 IE 进程.
- firefox 和 google-chrome 需要在特定的模式和配置下启动，这实际上意味着只要附加到正在运行的实例在技术上是不可能的.
- Reconnecting to an existing Browsing Context is a browser specific feature, hence can't be implemented in a generic way.
- With internet-explorer, it's possible to iterate over the open windows in the OS and find the right IE process to attach to.
- firefox and google-chrome needs to be started in a specific mode and configuration, which effectively means that just attaching to a running instance isn't technically possible.
