This package is inspired by jPowerShell and allows one to run and remote-control a PowerShell session. Use this if you don't have a static script that you want to execute, bur rather run dynamic commands.
go get github.com/bhendo/go-powershell
To start a PowerShell shell, you need a backend. Backends take care of starting
and controlling the actual powershell.exe process. In most cases, you will want
to use the Local backend, which just uses os/exec
to start the process.
package main
import (
"fmt"
ps "github.com/bhendo/go-powershell"
"github.com/bhendo/go-powershell/backend"
)
func main() {
// choose a backend
back := &backend.Local{}
// start a local powershell process
shell, err := ps.New(back)
if err != nil {
panic(err)
}
defer shell.Exit()
// ... and interact with it
stdout, stderr, err := shell.Execute("Get-WmiObject -Class Win32_Processor")
if err != nil {
panic(err)
}
fmt.Println(stdout)
}
You can use an existing PS shell to use PSSession cmdlets to connect to remote computers. Instead of manually handling that, you can use the Session middleware, which takes care of authentication. Note that you can still use the "raw" shell to execute commands on the computer where the powershell host process is running.
package main
import (
"fmt"
ps "github.com/bhendo/go-powershell"
"github.com/bhendo/go-powershell/backend"
"github.com/bhendo/go-powershell/middleware"
)
func main() {
// choose a backend
back := &backend.Local{}
// start a local powershell process
shell, err := ps.New(back)
if err != nil {
panic(err)
}
// prepare remote session configuration
config := middleware.NewSessionConfig()
config.ComputerName = "remote-pc-1"
// create a new shell by wrapping the existing one in the session middleware
session, err := middleware.NewSession(shell, config)
if err != nil {
panic(err)
}
defer session.Exit() // will also close the underlying ps shell!
// everything run via the session is run on the remote machine
stdout, stderr, err = session.Execute("Get-WmiObject -Class Win32_Processor")
if err != nil {
panic(err)
}
fmt.Println(stdout)
}
Note that a single shell instance is not safe for concurrent use, as are remote
sessions. You can have as many remote sessions using the same shell as you like,
but you must execute commands serially. If you need concurrency, you can just
spawn multiple PowerShell processes (i.e. call .New()
multiple times).
Also, note that all commands that you execute are wrapped in special echo
statements to delimit the stdout/stderr streams. After .Execute()
ing a command,
you can therefore not access $LastExitCode
anymore and expect meaningful
results.
