我有一个调用ServiceFabricSDK PowerShell模块来触发Azure Service Fabric应用程序部署的PowerShell脚本。当我直接调用PowerShell时，所有工作都正常，但如果我使用powershell命令从cmd文件中调用它，事情就会变得混乱起来，看起来在我的PowerShell脚本和它调用的模块之间会丢失一些上下文。从cmd调用PowerShell，当PowerShell调用另一个模块时，上下文会丢失
这里就是我的意思是：
我的PowerShell脚本需要的应用程序名称和夫妇更多的参数，进口ServiceFabricSDK.psm1，运行Connect-ServiceFabricCluster连接到本地服务织物集群，并最终调用Publish-NewServiceFabricApplication启动部署：
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
如果我运行它直接这一切工作正常：
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

ApplicationParameters : { "HelloWorldServiceType_InstanceCount" = "2" }
Create application succeeded.
我也有appStart.cmd文件，该文件调用映射到PowerShell中：
@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
没有什么比只是打电话到该PowerShell的更多的是，但不幸的是，部署失败，因为模块看不到群连接：
G:\repo>appStart HelloWorld
powershell G:\repo\build\scripts\Deploy-Application.ps1 -applicationName "HelloWorld" -repoTargetPath "G:\repo\\target\\" -targetEnvironment "dev.local"

我玩它和Connect-ServiceFabricCluster结果可以通过Get-ServiceFabricClusterConnection来检查，这就是Publish-NewServiceFabricApplication.ps1正在做的事情。我可以在调用Publish-NewServiceFabricApplication.ps1之前在PowerShell中运行它，并且它会返回正确的连接数据，即使从appStart.cmd运行。 为什么在调用脚本时连接丢失？
根据运行PowerShell的版本，会发生什么，当你添加[-MTA或-STA]（https://stackoverflow.com/questions/127188/could-you-explain-sta-and-mta）参数：'call powershell -MTA％ScriptsPath％\\ Deploy-Application.ps1 -applicationName“％ 1“-repoTargetPath”％BaseDir％\\ target \\“-targetEnvironment”dev.local“' – iRon
@iRon没有区别。 – MarcinJuraszek
试试模式： 'powershell -Command {％ScriptsPath％\\ Deploy-Application.ps1 -applicationName \“％1 \”-repoTargetPath \“％BaseDir％\\ target \\\”-targetEnvironment \“dev。 local \“}' –
