处理远程连接异常

Question

此脚本的预期结果是找出主机列表中的 PowerShell 版本。我想在远程机器关闭或没有启用远程处理时处理异常。但是，catch 似乎没有输入。只会出现来自 PowerShell 的标准红色火焰状错误消息。

我需要做什么来捕获异常？

X:\Scripts\PSAutomation> Get-Content .\get-versions.ps1
server_list = @(
   'CAPPY'
)

$server_list |
   ForEach-Object {
       Try {
           Invoke-Command -ComputerName $_ {$PSVersionTable.PSVersion}
       }
       Catch
       {
           Write-Host "Failed to connect to $_"
       }
   }
X:\Scripts\PSAutomation> .\get-versions.ps1
[CAPPY] Connecting to remote server CAPPY failed with the following error message : WinRM cannot process the
request. The following error occurred while using Kerberos authentication: Cannot find the computer CAPPY. Verify
that the computer exists on the network and that the name provided is spelled correctly. For more information, see
the about_Remote_Troubleshooting Help topic.
    + CategoryInfo          : OpenError: (CAPPY:String) [], PSRemotingTransportException
    + FullyQualifiedErrorId : NetworkPathNotFound,PSSessionStateBroken

Answer 1

只需将该调用的 ErrorAction 设置为 stop:

Invoke-Command -ComputerName "sdf" {$PSVersionTable.PSVersion} -ErrorAction Stop
