Question

我正在尝试编写一个在后台执行控制台命令并侦听StdOut和StdErr的函数。如果发生错误，它将抛出StdErr和StdOut。我正在尝试使用Autohotkey。首先，我尝试使用WScript.Shell COM对象，但是StdErr和StdOut始终为空，尽管StdOut绝对应该为非空。 WScript.Shell COM Object信息不多，所有Microsoft文档都在技术档案中。

Util_Command(command) {
    dhw := A_DetectHiddenWindows
    DetectHiddenWindows On
    Run "%ComSpec%" /k,, Hide, pid
    while !(hConsole := WinExist("ahk_pid" pid))
        Sleep 10
    DllCall("AttachConsole", "UInt", pid)
    DetectHiddenWindows %dhw%
    objShell := ComObjCreate("WScript.Shell")
    objExec := objShell.Exec(command)
    While (!objExec.Status) {
        Sleep 100
    }
    err := objExec.ExitCode
    StdErr := objExec.StdErr.ReadAll()
    StdOut := objExec.StdOut.ReadAll()
    DllCall("FreeConsole")
    Process Exist, %pid%
    if (ErrorLevel == pid) {
        Process Close, %pid%
    }
    if (err) {
        if (!StdErr) {
            throw StdOut
        }
        throw StdErr
    }
}

try {
    Util_Command("""C:\Program Files (x86)\Resource Hacker\ResourceHacker.exe"" -open ""non/existent/dir"" -save ""C:\Users\486B~1\AppData\Local\Temp\~temp5812406.res"" -action compile")
} catch e {
    MsgBox % e
}

然后我尝试使用GetStdHandle进行操作。在SciTe4Autohotkeys（或在任何控制台中）中，句柄已成功创建，但是在尝试写入StdInn或读取StdOut / StdErr时，出现ERROR_ACCESS_DENIED（5）。但是，写StdOut / StdErr或阅读StdInn效果很好，但对我来说却没用。然后，我尝试在没有控制台的情况下启动它，并且无法创建错误为ERROR_SEM_NOT_FOUND（187）的句柄。在脚本的开头，它将以隐藏模式启动cmd，并附加到它。如何获得具有适当读/写访问权限的附加控制台的句柄？

Util_Command(lpCommand) {
    dhw := A_DetectHiddenWindows
    DetectHiddenWindows On
    Run "%ComSpec%" /k,, Hide, pid
    while !(hConsole := WinExist("ahk_pid" pid))
        Sleep 10
    DllCall("AttachConsole", "UInt", pid)
    DetectHiddenWindows %dhw%
    hStdIn := DllCall("GetStdHandle", "Int", -10)
    hStdOut := DllCall("GetStdHandle", "Int", -11)
    hStdErr := DllCall("GetStdHandle", "Int", -12)
    StrPut(lpCommand, "UTF-8")
    VarSetCapacity(lpCommand, 1024)
    VarSetCapacity(lpStdErrBuffer, 2048)
    a := DllCall("WriteFile"
        , "Ptr", hStdIn
        , "Ptr", &lpCommand
        , "UInt", 1024
        , "UInt", 0
        , "UInt", 0)
    a := DllCall("ReadFile"
        , "Ptr", hStdOut
        , "Ptr", &lpStdOutBuffer
        , "UInt", 2048
        , "UInt", 0
        , "UInt", 0)
    a := DllCall("ReadFile"
        , "Ptr", hStdErr
        , "Ptr", &lpStdErrBuffer
        , "UInt", 2048
        , "UInt", 0
        , "UInt", 0)
    FileAppend, stdErr - %lpStdErrBuffer%`nstdOut - %lpStdOutBuffer%`n, *
    DllCall("FreeConsole")
    Process Exist, %pid%
    if (ErrorLevel == pid) {
        Process Close, %pid%
    }
    if (err) {
        if (!StdErr) {
            throw StdOut
        }
        throw StdErr
    }
}

try {
    Util_Command("""C:\Program Files (x86)\Resource Hacker\ResourceHacker.exe"" -open ""non/existent/dir"" -save ""C:\Users\486B~1\AppData\Local\Temp\~temp5812406.res"" -action compile\n")
} catch e {
    MsgBox % e
}

可以做到，但是我不确定您要完成什么。

您使用WScript.Shell，然后在.Exec(ComSpec " /C cscript " command)方法中传递命令并返回exec.StdOut.ReadAll()

我有一个工作示例，如下所示，也许对您有帮助：

;// The following runs a command (add.vbs) 
;// and retrieves its output via StdOut:

InputBox, x,,"Enter two numbers"
MsgBox % """" RunWaitOne("add.vbs " x) """" ;// result in quotes
ExitApp

RunWaitOne(command)
{
    shell := ComObjCreate("WScript.Shell")
    exec := shell.Exec(ComSpec " /C cscript " command)
    return Substr(exec.StdOut.ReadAll(), 109)  ;//  remove 109 characters in WScript header
}

/* This is the external "add.vbs" command:
a=3
b=4
if WScript.Arguments.Count > 0 Then
    a=cint(WScript.Arguments.Item(0))
    b=cint(WScript.Arguments.Item(1))
End If
Dim StdOut : Set StdOut = CreateObject("Scripting.FileSystemObject").GetStandardStream(1)
x=a+b
StdOut.Write x
*/
