Question

我有两个PowerShell脚本。 Test-Stuff.ps1和Functions.ps1。 Test-Stuff.ps1依赖于Functions.ps1，包括一个函数，该函数将对函数Write-Host的开始和结束作为参数传递给函数Functions.ps1的调用。

只要作为参数传递的函数也不来自Test-Stuff.ps1，它就可以正常工作。在这种情况下，调用函数无法捕获传递给函数的参数。

# Let's stop whenever there is something wrong $ErrorActionPreference = "Stop" # Cleanup screen Clear-Host # We import the functions in that other PowerShell files Import-Module "$PSScriptRoot\Functions.ps1" -Force # Works fine Invoke { Set-Location -Path $PSScriptRoot } "Change Current Working Directory to $PSScriptRoot" # works fine too Invoke { Write-Host "Testing" -ForegroundColor Red } $configurationFileName = "Preprod.json" # Works just fine $configuration = Invoke { Get-Content -Raw -Path $configurationFileName | ConvertFrom-Json } "Fetch configuration" $userName = $configuration.userName $password = $configuration.serviceAccountPassword # Does not work $credential = Invoke { New-Credential $userName $password } "Fetch credential"

Functions.ps1

Function Write-Start($text) { Write-Host ([System.Environment]::NewLine + "${text}...") -ForegroundColor Gray } Function Write-Stop($text) { Write-Host ("${text}: Done") -ForegroundColor Green } Function Invoke([scriptblock]$scriptBlock, $text) { Write-Start $text $result = $scriptBlock.Invoke() Write-Stop $text return $result }

.\TestStuff.ps1

GetNewClosure

我试图利用$credential = Invoke { New-Credential $userName $password }.GetNewClosure() "Fetch credential"

self::where('user_id', $user_id)
      ->where('amount_due','<', 'amount_repaid')
      ->where('loan_type', $loan_type)
      ->get()

...但是似乎没有太大帮助，如何强制捕获传递的函数参数？

Answer 1

问题似乎出在脚本块New-Credential $userName $password的内容上。我不熟悉该cmdlet，是您编写或导入的模块中的cmdlet吗？如果它是有效的cmdlet，则似乎参数的内容存在问题，或者没有与之匹配的“重载”。

也许您应该.Trim()和.ToString()那个$Configuration.userName

Powershell中的闭包和导入功能
