Question

我使用下面的代码来模拟Windows 7上的用户。这段代码被编译成一个dll并从python中调用。通常它可以工作，但最近我们一直看到主要执行失败并追溯到“WindowsIdentity.Impersonate(safeTokenHandle.DangerousGetHandle());”方法。当调用它时，它不会模拟用户，不会抛出任何错误，并且执行会立即停止（不会调用Console.WriteLine()之后）。

有什么想法吗？请？我不想承认我花了多少时间来解决这个问题。

谢谢！

        protected override bool ReleaseHandle()
        {
            return CloseHandle(handle);
        }
    }
}

根据Ben的建议更改为python：

    def impersonate_user(self, user_name, password, domain):
        handel=win32security.LogonUser(user_name, domain, password, win32con.LOGON32_LOGON_INTERACTIVE,win32con.LOGON32_PROVIDER_DEFAULT)
        win32security.ImpersonateLoggedOnUser(handel)
    print "Hello"

    return True

Answer 1

您可以使用LogonUser，ImpersonateLoggedOnUser和RevertToSelf直接从Python执行此操作。

就这样做，切掉C＃，这只会让事情变得复杂。

迟到回答，但刚刚遇到这个问题。将LOGON32_LOGON_INTERACTIVE更改为LOGON32_LOGON_BATCH (4)

Windows模拟无提示失败，没有错误，并结束执行
