Select 基于用户输入的 CSV 文件中 WinSCP .NET 程序集的 SFTP 连接数据

Question

我有这个 PowerShell 代码。效果很好。但是当我向 db.csv 添加更多行时，它不起作用并且 return 错误代码：

Exception calling "Open" with "1" argument(s): "Connection has been unexpectedly closed. Server sent command exit status 0.
Authentication log (see session log for details):
Using username "username".
Authentication failed."
At C:\Users\me\Desktop\testeScript\CollectLog.ps1:41 char:5
+ $session.Open($sessionOptions)
+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+ CategoryInfo : NotSpecified: (:) [], MethodInvocationException
+ FullyQualifiedErrorId : SessionRemoteException

例如，当我在 db.csv 中只有两行时，脚本运行良好

HostName,IP
name1,10.10.1.1
name2,10.10.1.2

我尝试在 CSV 文档中使用 19 主机名和 Ip 地址行并且工作正常，但是当我只添加 1 个停止工作时。

19 件作品 20+ 不工作..

有什么想法吗？（谢谢你，对不起我的英语）

Add-Type -Path "WinSCPnet.dll"
 
$Name = @()
$ip = @()
 
Import-Csv db.csv |`
    ForEach-Object {
        $Name += $_.HostName
        $ip += $_.IP
    }
 
$inputID = Read-Host -Prompt "Type ID"
 
if ($Name -contains $inputID)
    {
    $Where = [array]::IndexOf($Name, $inputID)
    Write-Host "IP: " $ip[$Where]
    }
 
# Set up session options
$sessionOptions = New-Object WinSCP.SessionOptions -Property @{
    Protocol = [WinSCP.Protocol]::Sftp
    HostName = "$ip"
    UserName = "username"
    Password = "password"
    GiveUpSecurityAndAcceptAnySshHostKey = "true"
}
 
$session = New-Object WinSCP.Session
 
try
{
    # Connect
    $session.Open($sessionOptions)
 
    # Transfer files
    $session.GetFiles("/C:/Program Files/Common Files/logs/Device.log", "E:\loguri\Log\Arhive\*").Check()
}
finally
{
    $session.Dispose()
}
 
Compress-Archive -Path "E:\loguri\Log\Arhive\Device.log" -DestinationPath "E:\loguri\Log\Arhive$inputID.zip" -Update
Remove-Item -Path "E:\loguri\Log\Arhive\Device.log" -Force

正如 Theo 所说，您无需将 CSV 分成两个数组。像这样导入

$db = import-csv 'db.csv'

您可以 $db[0]、$db[1] 访问每一行，CSV 中的每一列都将是属性，例如$db[0].Hostname 和 $db[0].IP

读入输入后，您只需 select 数组 $db 中的条目。也许像这样。但是，您的代码和我的代码都没有涵盖不匹配的情况！

$entry = $db -match $inputID

那么你的session会这样定义

$sessionOptions = New-Object WinSCP.SessionOptions -Property @{
    Protocol = [WinSCP.Protocol]::Scp
    HostName = $entry.ip
    UserName = "username"
    Password = "password"
    GiveUpSecurityAndAcceptAnySshHostKey = "true"
}

综上所述，鉴于您收到的错误消息，username/password 和 ip 的组合似乎无效。

Add-Type -Path "WinSCPnet.dll"
 
$db = import-csv 'db.csv'
 
$inputID = Read-Host -Prompt "Type ID"
 
$entry = $db -match $inputID
 
# Set up session options
$sessionOptions = New-Object WinSCP.SessionOptions -Property @{
    Protocol = [WinSCP.Protocol]::Sftp
    HostName = $entry.IP
    UserName = "username"
    Password = "password"
    GiveUpSecurityAndAcceptAnySshHostKey = "true"
}
 
$session = New-Object WinSCP.Session
 
try {
    # Connect
    $session.Open($sessionOptions)
 
    # Transfer files
    $session.GetFiles("/C:/Program Files/Common Files/logs/Device.log", "E:\loguri\Log\Arhive\*").Check()
}
finally {
    $session.Dispose()
}

if (Test-Path "E:\loguri\Log\Arhive\Device.log") {
  Compress-Archive -Path "E:\loguri\Log\Arhive\Device.log" -DestinationPath "E:\loguri\Log\Arhive$inputID.zip" -Update
  Remove-Item -Path "E:\loguri\Log\Arhive\Device.log" -Force
}
