CreateProcessAsUserW 错误代码 6 无效句柄 JNA

Question

我正在使用 JNA 调用 Windows API。我想以特定用户的身份启动一个进程（无关紧要）。我使用的两个 API 调用是：

LogonUserW 成功，但 CreateProcessAsUserW 失败并出现错误 6。根据 Windows System Error Codes Doc，这对应于“ERROR_INVALID_HANDLE”。

据我所知，我传入的唯一句柄是用户句柄。我看不出这有什么问题。根据 LogonUserW 文档，

In most cases, the returned handle is a primary token that you can use in calls to the CreateProcessAsUser function. However, if you specify the LOGON32_LOGON_NETWORK flag, LogonUser returns an impersonation token that you cannot use in CreateProcessAsUser unless you call DuplicateTokenEx to convert it to a primary token.

但是，我不使用 LOGON32_LOGON_NETWORK。

一些结构参数有句柄，但我要么传递 NULL，要么它们由 API 调用而不是我填充。

这是我的代码的主要部分：

final PointerByReference userPrimaryToken =
    new PointerByReference();
System.out.printf(
    "ptr.peer = %d\n",
    Pointer.nativeValue(userPrimaryToken.getValue())
);

final boolean logonOk = MyWinBase.INSTANCE.LogonUserW(
    toCString(<my-username>), // hidden
    toCString("ANT"),
    toCString(<my-password>), // hidden
    /* This logon type is intended for batch servers, where
    processes may be executing on behalf of a user without their
    direct intervention. This type is also for higher
    performance servers that process many plaintext
    authentication attempts at a time, such as mail or web
    servers.*/
    WinBase.LOGON32_LOGON_BATCH,
    WinBase.LOGON32_PROVIDER_DEFAULT,
    userPrimaryToken
);
System.out.printf("ok = %b\n", logonOk);
System.out.printf(
    "ptr.peer = %d\n",
    Pointer.nativeValue(userPrimaryToken.getValue())
);

final STARTUPINFOW.ByReference startupInfoW =
    new STARTUPINFOW.ByReference();
startupInfoW.cb = startupInfoW.size();
startupInfoW.lpReserved = Pointer.NULL;
startupInfoW.lpDesktop = Pointer.NULL;
startupInfoW.lpTitle = Pointer.NULL;
startupInfoW.dwFlags
    = startupInfoW.dwX = startupInfoW.dwY
    = startupInfoW.dwXSize = startupInfoW.dwYSize
    = startupInfoW.dwXCountChars = startupInfoW.dwYCountChars
    = startupInfoW.dwFillAttribute
    = startupInfoW.wShowWindow
    = 0;
startupInfoW.cbReserved2  = 0;
startupInfoW.lpReserved2 = Pointer.NULL;
startupInfoW.hStdInput = startupInfoW.hStdOutput
    = startupInfoW.hStdError
    = Pointer.NULL;

final PROCESS_INFORMATION.ByReference processInformation =
    new PROCESS_INFORMATION.ByReference();
processInformation.hProcess = processInformation.hThread
    = Pointer.NULL;
processInformation.dwProcessId = processInformation.dwThreadId
    = 0;

final boolean createProcessOk = MyProcessThreadsApi.INSTANCE
    .CreateProcessAsUserW(
        userPrimaryToken.getPointer(),
        toCString("C:\Windows\System32\cmd.exe"),
        // execute and terminate
        toCString("/c whoami > whoami.txt"),
        Pointer.NULL,
        Pointer.NULL,
        false,
        WinBase.CREATE_UNICODE_ENVIRONMENT,
        new PointerByReference(),
        Pointer.NULL,
        startupInfoW,
        processInformation
    );
System.out.printf("ok = %b\n", createProcessOk);
System.out.printf(
    "dwProcessId = %d\n", processInformation.dwProcessId
);
System.out.printf(
    "last err code = %d\n",
    ErrHandlingApi.INSTANCE.GetLastError()
);

这是我的输出：

ptr.peer = 0
ok = true
ptr.peer = 1040
ok = false
dwProcessId = 0
last err code = 6

有什么建议吗？

看这段代码：

final PointerByReference userPrimaryToken = ...;

在线文档说它代表一个指向指针的指针，C 表示法void**
https://java-native-access.github.io/jna/4.2.1/com/sun/jna/ptr/PointerByReference.html
在 LogonUser 的文档中，它需要一个指向 HANDLE 的 PHALDLE 指针，这类似于指向指针的指针，因为 HANDLE 类似于指针（它被声明为 typedef void *HANDLE;）。
https://docs.microsoft.com/en-us/windows/win32/api/winbase/nf-winbase-logonuserw

BOOL LogonUserW(
  ....
  DWORD   dwLogonProvider,
  PHANDLE phToken
);

但是在 CreateProcessAsUser 的文档中指定此函数接受 HANDLE，而不是 PHANDLE
https://docs.microsoft.com/en-us/windows/win32/api/processthreadsapi/nf-processthreadsapi-createprocessasuserw

BOOL CreateProcessAsUserW(
  HANDLE                hToken,
  LPCWSTR               lpApplicationName,
  ....
);

所以我希望您传递的是 getValue 而不是 getPointer。通过使用 getPointer，您可以获得指针本身，在您的情况下，它 很可能 指向指针的指针。我不知道 JNA，但期望来自 WinAPI

final boolean createProcessOk = MyProcessThreadsApi.INSTANCE
    .CreateProcessAsUserW(
        userPrimaryToken.getValue(),
        ....
    );
