使用参数验证调用另一个脚本

Question

我正在写一个模块脚本，其中包含许多脚本。所以主脚本会调用另一个子脚本，这些子脚本有时也会调用其他脚本。其他脚本的调用将在同一会话中完成。我的问题是使用ValidateScript进行参数验证。

因此，主脚本将调用另一个名为NSX-Gather-AT-Main.ps1的子脚本，该NSX主脚本有16个参数，我需要以某种方式验证它们，如果验证失败，则返回异常。

在下面的脚本中(这是从主脚本调用的NSX-Gather-AT-Main.ps1 )没有所有的验证，但我只包括对不起作用的文件路径的验证，一旦我得到这个工作，我将添加其他验证。

每当我从主脚本调用脚本时，我都会得到以下错误：

E:\CGS-NSX-Gather-AT\NSX-Gather-AT-Main.ps1 : Cannot validate argument on parameter 'NsxOutputFilePath'. The "If ( -Not ($_ | Test-Path)) {Throw "Provided File path for NSX Outputs ($_) is not valid."}" validation script for the argument 
with value "E:\Testing-Scripts\Test-01\" did not return a result of True. Determine why the validation script failed, and then try the command again.
At line:1 char:554
+ ... word NotUsed -NsxOutputFilePath "E:\Testing-Scripts\Test-01\" -NsxScr ...
+                                     ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    + CategoryInfo          : InvalidData: (:) [NSX-Gather-AT-Main.ps1], ParameterBindingValidationException
    + FullyQualifiedErrorId : ParameterArgumentValidationError,NSX-Gather-AT-Main.ps1

我在主脚本中使用的Call命令如下所示：

. E:\CGS-NSX-Gather-AT\CGS-NSX-Gather-AT-Main.ps1 -NsxManagerFqdn CGSM-NSX.nfv.gss -NsxManagerPassword VMware1! -vCenterFqdn CGSM-VCSA.nfv.gss -vCenterUser administrator@vsphere.local -vCenterPassword VMware1! -NsxControllerPassword VMware1!VMware1! -HostingvCenterFQDN CGSM-VCSA.nfv.gss -HostingvCenterUser administrator@vsphere.local -HostingvCenterPassword VMware1! -PrimaryNsxManagerFqdn "NotUsed" -PrimaryNsxManagerPassword NotUsed -PrimaryNsxvCenterFqdn NotUsed -PrimaryNsxvCenterUser NotUsed -PrimaryNsxvCenterPassword NotUsed -NsxOutputFilePath E:\Testing-Scripts\Test-01\ -NsxScriptFilePath "E:\Testing-Scripts\Test-02"

NSX-Gather-AT-Main.ps1脚本如下所示：

感谢@Mathias R.Jessen，您需要添加其他{$True}。据我所知，在验证脚本中使用IF条件时，您需要确保在某一点上为真，因此您需要添加IF和Else，以确保验证将转到$Flase或$True。

因此，要更改上述脚本中的最后一个参数，只需添加Else {$True}，如下所示：

#   15th Parameter will be the Path to the file where the outputs of this script will be dumped to.
[Parameter(Mandatory=$True)]
[ValidateNotNullOrEmpty()]
[ValidateScript({If ( -Not ($_ | Test-Path)) {Throw "Provided File path for NSX Outputs ($_) is not valid."} Else {$True}})]
[String]$NsxOutputFilePath,

    #-----------------------------------

#   16th Parameter will be the Path to the file where the NSX Subscripts and modules located.           
[Parameter(Mandatory=$True)]
[ValidateNotNullOrEmpty()]
[ValidateScript({If ( -Not ($_ | Test-Path)) {Throw "Provided File path for NSX Script ($_) is not valid."}  Else {$True}})]        
[String]$NsxScriptFilePath
