我正在开发一个使用 Selenium 来控制浏览器的应用程序。 Selenium 在初始化时启动浏览器，因此我从不直接在浏览器的 .exe 上调用 Process.Start。我希望 Selenium 及其所有子进程在与我的应用程序不同的用户下运行(因为我不希望它访问我的源代码)。使用找到的模拟样本 here ，我试图用模拟包装 Selenium 代码，但似乎所有子进程都是由启动其父进程的用户启动的。

有谁知道用模拟用户包装一段代码并让所有子进程以模拟用户的权限启动的方法？如果没有，实现这一目标的最佳策略是什么？在另一个进程中运行所有 Selenium 逻辑并以某种方式将命令传递给它？

最佳答案

试试这个。

本类(class)让您能够以用户身份处理午餐，

我在这里使用 Explorer session 。
