为什么从golang（golang）调用Powershell Start-Process不起作用？

我希望从一个不同的用户下运行一个Windows批处理脚本来运行go程序。 运行go的用户拥有比应该运行批处理脚本的用户更多的权限。

从开始有几个选项可用于在Windows上的不同用户下执行进程，例如直接使用syscall包在窗口中编写Windows调用。 我还没有尝试过，但我已经尝试使用PsExec和Powershell。 Powershell是首选，因为它在Windows 2008 R2上作为标准安装。

下面的代码演示了我有的问题。 在下面的演示中，我运行了一个批处理脚本。 这个批处理脚本直接调用Powershell脚本，然后从go程序调用它。 结果是不同的。 Powershell脚本输出3个文件，但是从go中调用时只输出2个文件。

为了完整起见，我还展示了用户是如何创build的。

• 我怎样才能清除与Windows Golang控制台？
• 我想在Windows上开发并部署到Google App Engine
• Golang：Windows下的HTTP部署
• Google Go Win：找不到导入“http”
• GO可以用作应用程序中的脚本引擎吗？

C：\计算器\ demo.bat：

C：\计算器\ demo.ps1

 write-output "test output" | out-file C:\Users\Tom\started.txt $credentials = New-Object System.Management.Automation.PSCredential -ArgumentList @("Tom",(ConvertTo-SecureString -String "_Jerry123_" -AsPlainText -Force)) Start-Process C:\stackoverflow\whoami.bat -WorkingDirectory C:\stackoverflow -Credential ($credentials) -Wait write-output "test output" | out-file C:\Users\Tom\finished.txt 

C：\计算器\ demo.go

 package main import ( "fmt" "os" "os/exec" ) func main() { run(exec.Command("PowerShell", "-Command", "C:\\stackoverflow\\demo.ps1")) } func run(cmd *exec.Cmd) { cmd.Stdout = os.Stdout cmd.Stderr = os.Stderr cmd.Stdin = os.Stdin err := cmd.Start() if err != nil { panic(err) } err = cmd.Wait() if err != nil { panic(err) } fmt.Println("Done") } 

C：\计算器\ whoami.bat：

 whoami > C:\Users\Tom\whoami.txt 

现在，结果 – 在批处理脚本中调用时，会看到文件starts.txt，whoami.txt，finished.txt全部被创build。 从go中调用时，只会创buildstarted.txt和finished.txt。 这是为什么？
