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及其所有子进程在不同于我的应用程序的用户下运行(因为我不希望它访问我的源代码).使用模拟样本
here,我试图用模拟包装Selenium代码,但似乎所有子进程都由启动其父进程的用户启动.
有没有人知道用户模仿包装代码块的方法,并使用模拟用户的权限启动所有子进程？如果没有,那么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逻辑并以某种方式管道命令到它？
解决方法
试试这个 .
本课程使您能够以用户身份进行午餐过程,
在这里,我使用Explorer会话.
