TFS电源外壳任务未将正确的参数数量传递给脚本

Question

我遇到了一个问题，即作为持续集成过程的一部分运行电源外壳脚本任务，并且脚本未收到正确数量的参数。

这是我正在

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 


} 

剧本，如果我在一个PowerShell功能运行脚本我正确地获取价值

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

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

这是输出

问题出现在我试图通过TFS

，我传递给脚本的参数有以下几种

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

变量$ takePhysicalPath是从来没有过，下面是输出

任何想法？

Answer 1

您必须编写-takePhysicalPath而不是$takePhysicalPath。作为替代方案，您可以使用Parameter属性并使其成为positional。

Answer 2

我测试了脚本，只需在脚本末尾添加invoke命令，然后传递给该脚本的参数按预期工作。

确保您引用正确的PARAM，在您发布上述$ takePhy invoke命令我 sicalPath（注意字母“我”）是帕拉姆$ takePhysicalPath不一致

脚本应该是：

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
