从 cmd 调用 PowerShell，当 PowerShell 调用另一个模块时上下文丢失

Question

我有一个 PowerShell 脚本，它调用 ServiceFabricSDK PowerShell 模块来触发 Azure Service Fabric 应用程序部署。当我直接调用 PowerShell 时一切正常，但如果我使用 powershell 命令从 cmd 文件调用它，事情就会变得一团糟，看起来我的 PowerShell 脚本和模块之间的某些上下文丢失了它调用了。

我的意思是：

我的 PowerShell 脚本采用应用程序名称和更多参数，导入 ServiceFabricSDK.psm1、运行s Connect-ServiceFabricCluster 以连接到本地 Service Fabric 集群并最终调用 Publish-NewServiceFabricApplication 以开始部署：

param (
    [Parameter()]
    [ValidateNotNullOrEmpty()]
    [string]
    $applicationName,

    [Parameter()]
    [ValidateNotNullOrEmpty()]
    [string]
    $repoTargetPath,

    [Switch]
    $retail,

    [Parameter()]
    [ValidateNotNullOrEmpty()]
    $targetEnvironment = "dev.local"
)

# Load ServiceFabricSDK first
Write-Output "Loading Service Fabric SDK module"
Import-Module "$ENV:ProgramFiles\Microsoft SDKs\Service Fabric\Tools\PSModule\ServiceFabricSDK\ServiceFabricSDK.psm1"

# Connect to the local cluster
Write-Output "Connecting to local Service Fabric cluster"
Connect-ServiceFabricCluster | Out-Null
Write-Output "Successfully connected to local Service Fabric cluster"

$repoTargetPath = $repoTargetPath.TrimEnd('\')
$target = if($retail.IsPresent) { "retail" } Else { "debug" }
$applicationTargetBasePath = "$repoTargetPath\distrib$target\applications$applicationName"
$applicationPackagePath = "$applicationTargetBasePath\package\"
$applicationParametersFilePath = "$applicationTargetBasePath\applicationParameters$applicationName.$targetEnvironment.xml"

Write-Output "Deploying application $applicationName to local Service Fabric cluster"

# Deploy the application
Publish-NewServiceFabricApplication -ApplicationPackagePath $applicationPackagePath -ApplicationParameterFilePath $applicationParametersFilePath -ApplicationName "fabric:/$applicationName" -OverwriteBehavior Always -Verbose -SkipPackageValidation

如果我直接运行它一切正常:

PS G:\repo> .\build\scripts\Deploy-Application.ps1 -applicationName HelloWorld -targetEnvironment "dev.local" -repoTargetPath G:\repo\target\
Loading Service Fabric SDK module
Connecting to local Service Fabric cluster

ApplicationTypeVersion : 1.0.20170816-seed-1207928760
ApplicationParameters  : { "HelloWorldServiceType_InstanceCount" = "2" }

Create application succeeded.

我还有 appStart.cmd 调用该 PowerShell 的文件：

@if "%_echo%"=="" echo off

pushd
cd %BaseDir%

if "%1" == "" goto error

echo powershell %ScriptsPath%\Deploy-Application.ps1 -applicationName "%1" -repoTargetPath "%BaseDir%\target\" -targetEnvironment "dev.local"
call powershell %ScriptsPath%\Deploy-Application.ps1 -applicationName "%1" -repoTargetPath "%BaseDir%\target\" -targetEnvironment "dev.local"

GOTO :EOF

除了调用那个 PowerShell 之外别无他法，但不幸的是部署失败，因为模块看不到集群连接：

G:\repo>appStart HelloWorld
powershell G:\repo\build\scripts\Deploy-Application.ps1 -applicationName "HelloWorld" -repoTargetPath "G:\repo\target\" -targetEnvironment "dev.local"
Loading Service Fabric SDK module

我玩过它 Connect-ServiceFabricCluster 结果可以通过 Get-ServiceFabricClusterConnection 检查，这就是 Publish-NewServiceFabricApplication.ps1 正在做的事情。我可以在调用 Publish-NewServiceFabricApplication.ps1 之前在我的 PowerShell 中运行它 returns 正确的连接数据，即使运行来自 appStart.cmd。 为什么在调用脚本时连接丢失？

你可以尝试在Connect-ServiceFabricCluster:

之后将集群连接放入一个全局变量中

$global:clusterConnection = $clusterConnection
