使用PowerShell从SFTP服务器下载文件

PowerShell或中不支持SFTP。NET框架。因此,您必须使用外部SFTP库。

一种可能性(你在问题中标记了自己)是 WinSCP .NET assembly using WinSCP from PowerShell .

甚至还有一个 code example in PowerShell for SFTP download :

try
{
    # Load WinSCP .NET assembly
    Add-Type -Path "WinSCPnet.dll"
 
    # Setup session options
    $sessionOptions = New-Object WinSCP.SessionOptions -Property @{
        Protocol = [WinSCP.Protocol]::Sftp
        HostName = "example.com"
        UserName = "user"
        Password = "mypassword"
        SshHostKeyFingerprint = "ssh-rsa 2048 xxxxxxxxxxx...="
    }
 
    $session = New-Object WinSCP.Session
 
    try
    {
        # Connect
        $session.Open($sessionOptions)
 
        # Download files
        $transferOptions = New-Object WinSCP.TransferOptions
        $transferOptions.TransferMode = [WinSCP.TransferMode]::Binary
 
        $remotePath = "/home/user/*";
        $localPath = "d:\download\*";
        $transferResult =
            $session.GetFiles($remotePath, $localPath, $False, $transferOptions)
 
        # Throw on any error
        $transferResult.Check()
 
        # Print results
        foreach ($transfer in $transferResult.Transfers)
        {
            Write-Host "Download of $($transfer.FileName) succeeded"
        }
    }
    finally
    {
        # Disconnect, clean up
        $session.Dispose()
    }
 
    exit 0
}
catch [Exception]
{
    Write-Host "Error: $($_.Exception.Message)"
    exit 1
}

WinSCP GUI甚至可以 generate a PowerShell SFTP download code ,如上图所示,对于您的特定会话设置和传输选项:

• 使用WinSCP GUI登录服务器;
• 在远程文件面板中选择要下载的文件;
• 调用 下载

• 上 Transfer options dialog ,转到 传输设置>生成代码 ;
• 在“生成传输代码”对话框中,选择 .NET assembly code tab 选择 PowerShell 语言
