如何为创建调用我的应用程序的进程的用户获取访问令牌?

How can I get the Access Token for the user that created the process that called my application?

我需要使用该令牌进行模拟，其目的是访问该用户applicationData中的文件.

I need to use that Token for impersonation, the idea is to access a file in that users applicationData.

P.S.模仿用户的应用程序是在系统下运行的服务.

推荐答案

检查MSDN，所有这些API都有据可查. 您可能想要执行以下操作:

Check MSDN, all this API is well documented. You probably want to do something like this:

HANDLE thisToken, thisProcess;

thisProcess = OpenProcess( PROCESS_ALL_ACCESS, FALSE, GetCurrentProcessId() );
OpenProcessToken( thisProcess, TOKEN_ALL_ACCESS, &thisToken );

尽管您可能想要的访问量少于该数量. 这将为您获取当前进程的令牌.

Though you probably want less access than that. This will get you the token for the current process.
