powershell - 在Powershell中捕获网络使用异常

Question

我很难在Powershell中捕获网络使用异常。

foreach ($k in $file){

        try{
            net use \\$k\share $password /USER:$username > null 
            Copy-Item D:\setup.exe \\$k\share 
            net use \\$k\share /delete > null 
            write-host "Copied file to \\$k\share"

        }
        catch [System.Exception]{
            continue
        }

}

如果脚本无法通过计算机验证，我希望脚本静默继续，但出现以下错误

net : System error 1326 has occurred.
At D:\Script\log_into.ps1:25 char:17
+                 net use \\$k\share $password /USER:$username > null
+                 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    + CategoryInfo          : NotSpecified: (System error 1326 has occurred.:String) [], RemoteException
    + FullyQualifiedErrorId : NativeCommandError

The user name or password is incorrect.
net : The network connection could not be found.
At D:\Script\log_into.ps1:27 char:17
+                 net use \\$k\share /delete > null
+                 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    + CategoryInfo          : NotSpecified: (The network con...d not be found.:String) [], RemoteException
    + FullyQualifiedErrorId : NativeCommandError

而是使用PowerShell cmdlet映射驱动器，以便您可以正确捕获任何异常。

这仅适用于PowerShell 3.0及更高版本，因为较早版本中的-Credential参数存在一个错误(只是不起作用)。如果您需要v2兼容性，请发表评论，我会进行更新。

$userPass = ConvertTo-SecureString "password" -AsPlainText -Force
$Credential = New-Object -TypeName System.Management.Automation.PSCredential -ArgumentList $username, $userPass

foreach ($k in $file){

        try{
            New-PSDrive -Name Z -PSProvider FileSystem -Root \\$k\share -Credential $Credential;
            Copy-Item D:\setup.exe Z:\
            Remove-PSDrive -name Z
            write-host "Copied file to \\$k\share"

        }
        catch [System.Exception]{
            continue
        }

}
