TFS電源外殼任務未將正確的參數數量傳遞給腳本

Question

我遇到了一個問題，即作爲持續集成過程的一部分運行電源外殼腳本任務，並且腳本未收到正確數量的參數。

這是我正在

Param 
(
    [string]$directory_path, 
    [string]$website_name, 
    [string]$app_n, 
    [string]$takePhysicalPath 
) 
$ScriptBlockContent = 
{ 
    $dirPath = $args[0] 
    $websiteName = $args[1] 
    $appName = $args[2] 
    $takePhysicalPath = $args[3] 
    $physicalPath = $False 

    Write-Host "Param: directory_path: " $dirPath 
    Write-Host "Param website_name: " $websiteName 
    Write-Host "Param app_n: " $appName 
    Write-Host "Param takePhysicalPath: " $takePhysicalPath 

    Write-Host 'Parameter Count: ' $args.Count 

    if ([bool]::TryParse($takePhysicalPath, [ref]$physicalPath)) 
    { 
     Write-Host 'Parsed: ' $takePhysicalPath ' -> ' $physicalPath 
    } 
    else 
    { 
     Write-Host 'Not Parsed' 
    } 

    Write-Host $dirPath 
    Write-Host $websiteName 
    Write-Host $appName 
    Write-Host $physicalPath 


} 

劇本，如果我在一個PowerShell功能運行腳本我正確地獲取價值

$directory_path = "C:\SolutionsContent" 
$website_name = "websiteName" 
$app_n = "Styles" 
$takePhysicalPath = "true" 

Invoke-Command -ScriptBlock $ScriptBlockContent -ArgumentList $directory_path, $website_name, $app_n, $takePhysicalPath 

這是輸出

問題出現在我試圖通過TFS

，我傳遞給腳本的參數有以下幾種

-directory_path "C:\SolutionsContent" -website_name "websiteName" -app_n "Styles" -takePhysicalPath "true" 

變量$ takePhysicalPath是從來沒有過，下面是輸出

任何想法？

Answer 1

您必須編寫-takePhysicalPath而不是$takePhysicalPath。作爲替代方案，您可以使用Parameter屬性並使其成爲positional。

Answer 2

我測試了腳本，只需在腳本末尾添加invoke命令，然後傳遞給該腳本的參數按預期工作。

確保您引用正確的PARAM，在您發佈上述$ takePhy invoke命令我 sicalPath（注意字母「我」）是帕拉姆$ takePhysicalPath不一致

腳本應該是：

Param 
(
    [string]$directory_path, 
    [string]$website_name, 
    [string]$app_n, 
    [string]$takePhysicalPath 
) 
$ScriptBlockContent = 
{ 
    $dirPath = $args[0] 
    $websiteName = $args[1] 
    $appName = $args[2] 
    $takePhysicalPath = $args[3] 
    $physicalPath = $False 

    Write-Host "Param: directory_path: " $dirPath 
    Write-Host "Param website_name: " $websiteName 
    Write-Host "Param app_n: " $appName 
    Write-Host "Param takePhysicalPath: " $takePhysicalPath 

    Write-Host 'Parameter Count: ' $args.Count 

    if ([bool]::TryParse($takePhysicalPath, [ref]$physicalPath)) 
    { 
     Write-Host 'Parsed: ' $takePhysicalPath ' -> ' $physicalPath 
    } 
    else 
    { 
     Write-Host 'Not Parsed' 
    } 

    Write-Host $dirPath 
    Write-Host $websiteName 
    Write-Host $appName 
    Write-Host $physicalPath 


} 
Invoke-Command -ScriptBlock $ScriptBlockContent -ArgumentList $directory_path, $website_name, $app_n, $takePhysicalPath
