在Azure中的DevOps发布管道与PARAM块问题

Question

我写我自己的PowerShell脚本上传过SFTP一些文件在Azure中的DevOps发布管道。

本地我做剧本的工作，但要使它在流水线工作就像一个内嵌脚本是不会这么好。

我建立我的剧本了默认PARAMS这样我就可以输入本地测试，但是当我在Azure中运行它，我得到错误信息

PARAM：术语“PARAM”不被识别为cmdlet，函数，脚本文件或可操作的程序的名称。检查名称的拼写，或是否包含一个路径，验证路径是否正确，然后再试一次。

不允许我在Azure中使用param()？

param (
    $Localpath = $env:System_ArtifactsDirectory,
    $Remotepath = $env:sFTP_Remotepath,
    $Hostname = $env:sFTP_Host,
    $Username = $env:sFTP_Username,
    $Password = $env:sFTP_Password,    
    $HostKeyFingerprint = $env:sFTP_Hostkey,
    $WinSCPnetdllpath =  "$env:System_ArtifactsDirectory\WinSCPnet.dll"
)

try
{
    Write-Host "Hostname:" $Hostname
    Write-Host "Username:" $Username
    Write-Host "Password: ****"
    Write-Host "Remotepath:" $Remotepath
    Write-Host "Localpath:" $Localpath
    Write-Host "HostKeyFingerprint:" $HostKeyFingerprint
    Write-Host "WinSCPnetdllpath:" $WinSCPnetdllpath
    # Load WinSCP .NET assembly
    Add-Type -Path $WinSCPnetdllpath

    # Setup session options
    $sessionOptions = New-Object WinSCP.SessionOptions -Property @{
        Protocol = [WinSCP.Protocol]::Sftp
        HostName = $Hostname
        UserName = $Username
        Password = $Password
        SshHostKeyFingerprint = $HostKeyFingerprint
    }

    $session = New-Object WinSCP.Session

    try
    {
        # Connect
        $session.Open($sessionOptions)

        # Upload files, collect results
        $transferResult = $session.PutFiles($Localpath, $Remotepath, $False)

        Write-Host ("Found {0} of files to upload" -f $transferResult.Transfers.Count)

        # Iterate over every transfer
        foreach ($transfer in $transferResult.Transfers)
        {
            # Success or error?
            if ($transfer.Error -eq $Null)
            {
                Write-Host (" - Upload of '{0}' .. Success" -f $transfer.FileName)                              
            }
            else
            {
                Write-Host (" - Upload of '{0}' .. Failed: {1}" -f $transfer.FileName, $transfer.Error.Message)
            }
        }
    }
    finally
    {
        # Disconnect, clean up
        $session.Dispose()
    }

    exit 0
}
catch [Exception]
{
    Write-Host ("Error: {0}" -f $_.Exception.Message)
    exit 1
}

有周围放置一些行内包装语句创建PowerShell脚本会导致错误。它似乎并不目前支持在线电话帕拉姆块。你可以，而不是仅仅引用您的参数，而不是直接。

$ErrorActionPreference = 'stop'
...
if (!(Test-Path -LiteralPath variable:\LASTEXITCODE)) {
    Write-Host '##vso[task.debug]$LASTEXITCODE is not set.'
} else {
    Write-Host ('##vso[task.debug]$LASTEXITCODE: {0}' -f $LASTEXITCODE)
    exit $LASTEXITCODE
}

有关于它的这个github issue一些讨论。您也可以通过代码一眼，因为它是开源的。
