Powershell posh-ssh：如何存储Invoke-SSHCommand的结果？

Question

如何在关闭连接后存储Invoke-SSHCommand的结果以供使用？

我尝试了两种不同的方式：

#method 1
$result = Invoke-SSHCommand -Index 0 -Command "ls /somepath"

#method 2
Invoke-SSHCommand -Index 0 -Command "ls /somepath" -OutVariable $result

两个方法

后，变量$result为空

Answer 1

这对我很有用：

# Create SSH Session
$ssh = New-SSHSession -ComputerName $PC01 -Credential $credential -AcceptKey 1

# Invoke SSH command and capture output as string (you can return the full object if you like, I just needed the string Out)
$ret = $(Invoke-SSHCommand -SSHSession $ssh -Command "racadm getconfig -g cfgUserAdmin -i 2").Output

# return object is a String - if you want it as an array of strings for each row returned
$ret = $ret.split("`n")

Answer 2

这对我有用：

#method 1
$CurrentSession=New-SSHSession -ComputerName x.x.x.x -Credential (Get-Credential) 
$result = Invoke-SSHCommand -SSHSession $CurrentSession -Command "ls /somepath"
$result.Output

Answer 3

从$中删除-OutVariable $result，它应该有效。

Invoke-SSHCommand -Index 0 -Command "ls /somepath" -OutVariable result

正在处理命令中的$result，返回null，然后尝试将Invoke-SSHCommand的结果输出为null，据我所知
