TFS power shell任务没有将正确数量的参数传递给脚本

Question

我遇到了一个问题，我在执行power shell脚本任务时将其作为持续集成过程的一部分，并且脚本没有收到正确数量的参数。

这是我正在运行的脚本

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


}

如果我在powershell函数中运行脚本，我正确地获取值

$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

当我尝试通过TFS运行时出现问题

我传递给脚本的参数是以下

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

永远不会传递变量$ takePhysicalPath，下面是输出

有什么想法吗？

Answer 1

您要写$takePhysicalPath而不是Parameter。作为替代方案，您可以使用{{1}} attribue并将其设为positional。

Answer 2

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

确保您引用了正确的参数，在您上面发布的调用命令中，$ takePhy i sicalPath（注意字母＆＃34; i ＆＃34;）是与param $ takePhysicalPath

不一致

脚本应为：

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
