如何创建交互式命令执行

My problem is the interaction with exec.command. I would like to automate RunAs on windows.

I want via this application launch other applications (eg Ccleaner, antivirus eset online, etc ...) on computers of my clients. So I create a adminsys account and I want to launch these various applications automatically with this account.

cmd := exec.Command("runas", user, nameProgram)

cmd.Stdout = os.Stdout
cmd.Stderr = os.Stderr

stdin, err := cmd.StdinPipe()
if err != nil {
    fmt.Println(err)
}
defer stdin.Close()
err = cmd.Start()
if err != nil {
    fmt.Println(err)
    return
}

time.Sleep(3 * time.Second)
io.WriteString(stdin, password)

err = cmd.Wait()
if err != nil {
    fmt.Println(err)
    return
}

This does not work!

The errors with runas.

Erreur de RUNAS : Impossible d’exécuter - C:\program.exe 
1326 : Le nom d’utilisateur ou le mot de passe est incorrect.

It looks like he does not recognize the password. This works when I do it directly in the command prompt

I'm not running windows, and the code you have in your question works for me. So, the following may not solve your problem, but this is an alternative for passing string to a command.

I created this basic command named pass in order to assert the correctness of the password:

func main() {

    fmt.Print("Enter your password please: ")
    reader := bufio.NewReader(os.Stdin)
    password, err := reader.ReadString('
')
    if err != nil {
        fmt.Println("An error occurred while reading line")
    }

    // Remove the line break
    password = password[:len(password)-1]

    if password == "Secret pass" {
        fmt.Println("Success !")
    } else {
        fmt.Println("Failure !")
    }

}

Now, instead of working with pipe, set the Stdin of the command to a new reader:

func main() {
    cmd := exec.Command("pass")
    cmd.Stdin = strings.NewReader("Secret pass!
")
    cmd.Stdout = os.Stdout
    _ = cmd.Run()
    // Failure

    cmd = exec.Command("pass")
    cmd.Stdin = strings.NewReader("Secret pass
")
    cmd.Stdout = os.Stdout
    _ = cmd.Run()
    // Success
}

Hope this helps.
