从 child 脚本连接两个 Azure Analysis Services 时出错

Question

我正在处理 PowerShell 脚本。我在这些脚本中有两个脚本，我正在一个接一个地连接两个 Azure 分析服务器。而这些脚本都是由主脚本调用的。我遇到错误

"Exception calling "Connect" with "1" argument(s): "Object reference not set to an instance of an object."

我的脚本代码如下

孩子 1.ps1

param(
    [String]
    $envName1,
    [String]
    $toBeDisconnect1
)

$loadInfo1 = [Reflection.Assembly]::LoadWithPartialName("Microsoft.AnalysisServices")
$server1 = New-Object Microsoft.AnalysisServices.Server

if($toBeDisconnect1 -eq "No")
{
    $server1.Connect($envName1)
    return $server1
}
elseif($toBeDisconnect1 -eq "Yes")
{
    $server1.Disconnect()
    Write-Host $server1 " has been disconnected."
}

孩子2.ps1

param(
    [String]
    $envName1,
    [String]
    $toBeDisconnect1
)

$loadInfo1 = [Reflection.Assembly]::LoadWithPartialName("Microsoft.AnalysisServices")
$server1 = New-Object Microsoft.AnalysisServices.Server

if($toBeDisconnect1 -eq "No")
{
    $server1.Connect($envName1)
    return $server1
}
elseif($toBeDisconnect1 -eq "Yes")
{
    $server1.Disconnect()
    Write-Host $server1 " has been disconnected."
}

MainParent.ps1

param(
    $filePath = "C:\Users\user1\Desktop\DBList.txt"
)

$command = "C:\Users\User1\Desktop\test1.ps1 –envName1 
asazure://aspaaseastus2.asazure.windows.net/mydevaas -toBeDisconnect1 No"
$Obj1 = Invoke-Expression $command
Start-Sleep -Seconds 15

$command1 = "C:\Users\User1\Desktop\test2.ps1 –envName2 
asazure://aspaaseastus2.asazure.windows.net/myuataas -toBeDisconnect2 No"
$Obj2 = Invoke-Expression $command1

错误在 MainParent 中。ps1

 Exception calling "Connect" with "1" argument(s): "Object reference not set to an instance of an 
 object."
 At C:\Users\User1\Desktop\test1.ps1:13 char:5

我的 AzureAnalysis Services dll 版本是 13.0.4495.10。我正在分享此信息，这可能是个问题。

Answer 1

似乎 Invoke-Expression 没有传递参数 envName1。我宁愿像下面这样正常调用子脚本：

$Obj1 = &"C:\Users\User1\Desktop\test1.ps1" -envName1 "asazure://aspaaseastus2.asazure.windows.net/mydevaas" -toBeDisconnect1 No | select -Last 1

$Obj2 = &"C:\Users\User1\Desktop\test2.ps1" -envName2 "asazure://aspaaseastus2.asazure.windows.net/myuataas" -toBeDisconnect2 No | select -Last 1

Answer 2

$command = "C:\Users\User1\Desktop\test1.ps1 –envName1 asazure://aspaaseastus2.asazure.windows.net/mydevaas -toBeDisconnect1 No"

仔细查看 envName1 之前的连字符。它实际上是 - (en-dash) 而不是 -（连字符）。这就是没有传递 envName1 的原因。第二个参数 toBeDisconnect1 正确。

如何区分？ -（连字符）短于 – (en-dash) :)
