我正在编写一个需要执行管理任务的pyqt应用程序。我希望以提升的特权启动脚本。我知道这个问题在SO或其他论坛中被问过很多次。但是人们建议的解决方案是看看这个SO问题 从Python脚本中请求UAC提升吗?
但是,我无法执行链接中给出的示例代码。我已将此代码放在主文件之上,并尝试执行它。
import os import sys import win32com.shell.shell as shell ASADMIN = 'asadmin' if sys.argv[-1] != ASADMIN: script = os.path.abspath(sys.argv[0]) params = ' '.join([script] + sys.argv[1:] + [ASADMIN]) shell.ShellExecuteEx(lpVerb='runas', lpFile=sys.executable, lpParameters=params) sys.exit(0) print "I am root now."
它实际上请求提升权限,但打印行从未执行。有人可以帮助我成功运行以上代码。提前致谢。
我的脚本可以与Preston Landers于2010年编写的模块/脚本一起使用。经过两天的互联网浏览后,我发现了该脚本,因为该脚本已深深地藏在pywin32邮件列表中。使用此脚本,可以更轻松地检查用户是否为admin,如果不是,则询问UAC / admin权限。它确实在单独的窗口中提供输出,以找出代码在做什么。脚本中还包含有关如何使用代码的示例。为了所有人在Windows上寻找UAC的利益,请查看以下代码。我希望它可以帮助寻求相同解决方案的人。在你的主脚本中可以使用以下命令:
import admin if not admin.isUserAdmin(): admin.runAsAdmin()
实际的代码是:
