用错误测试Azure自动机运行库: WriteErrorException

Question

因此，我在一个自动化帐户中的一个免费试用Azure订阅中输入了下面的代码。

这个Run Book的目的是在周末自动关闭我的VM，并在周一早上自动启动这个VM。在计划创建中没有任何问题。

参数被标记为“可选”，当所有外部参数字段都为空时，它确实选择了正确的虚拟机(ITAMTradingVPS)。那里也没问题。

然而，当我进行“测试”以确保所有的编码都是正确的，并且脚本做了它应该做的事情时，为什么我会得到以下错误，我需要做什么来修复这个错误呢？

Run Book是使用"Powershell运行簿“从自动化帐户刀片创建的

如果你需要任何进一步的信息，或需要我澄清任何事情，请随时发表评论。

谢谢

ITAMTradingVPS failed to stop. Error was:
+ CategoryInfo          : NotSpecified: (:) [Write-Error], WriteErrorException
+ FullyQualifiedErrorId : Microsoft.PowerShell.Commands.WriteErrorException


Status was 
+ CategoryInfo          : NotSpecified: (:) [Write-Error], WriteErrorException
+ FullyQualifiedErrorId : Microsoft.PowerShell.Commands.WriteErrorException

Exception of type 'Microsoft.PowerShell.Commands.WriteErrorException' was thrown.
+ CategoryInfo          : NotSpecified: (:) [Write-Error], WriteErrorException
+ FullyQualifiedErrorId : Microsoft.PowerShell.Commands.WriteErrorException

这是我对自动化过程的代码。

我在本地机器powershell上测试您的脚本，运行良好。但是在Azure runbook中运行它，得到与您相同的错误消息。

因为$StopRtn输出是这样的：

RequestId IsSuccessStatusCode StatusCode ReasonPhrase
--------- ------------------- ---------- ------------
                         True         OK OK          

因此，我们应该像这样修改powershell脚本：

param (

    [Parameter(Mandatory=$false)] 
    [String] $VMName ,

    [Parameter(Mandatory=$false)] 
    [String] $ResourceGroupName
)

$connectionName = "AzureRunAsConnection"
try
{
    # Get the connection "AzureRunAsConnection "
    $servicePrincipalConnection=Get-AutomationConnection -Name $connectionName         

    "Logging in to Azure..."
    Add-AzureRmAccount `
        -ServicePrincipal `
        -TenantId $servicePrincipalConnection.TenantId `
        -ApplicationId $servicePrincipalConnection.ApplicationId `
        -CertificateThumbprint $servicePrincipalConnection.CertificateThumbprint 
}
catch {
    if (!$servicePrincipalConnection)
    {
        $ErrorMessage = "Connection $connectionName not found."
        throw $ErrorMessage
    } else{
        Write-Error -Message $_.Exception
        throw $_.Exception
    }
}


# If there is a specific resource group, then get all VMs in the resource group,
# otherwise get all VMs in the subscription.
if ($ResourceGroupName -And $VMName) 
{ 
    $VMs = Get-AzureRmVM -ResourceGroupName $ResourceGroupName -Name $VMName
}
elseif ($ResourceGroupName)
{
    $VMs = Get-AzureRmVM -ResourceGroupName $ResourceGroupName

}
else 
{ 
    $VMs = Get-AzureRmVM
}

$vms
# Start each of the VMs
# Stop each of the VMs
foreach ($VM in $VMs)
{
    $StopRtn = $VM | Stop-AzureRmVM -Force -ErrorAction Continue
    $StopRtn
    Write-Output " this is $StopRtn "

    if ($StopRtn.IsSuccessStatusCode -eq 'True')
    {
        # The VM stopped, so send notice
        Write-Output ($VM.Name + " has been stopped")

    }
    else
    {
        # The VM failed to stop, so send notice
        Write-Output ($VM.Name + " failed to stopped")
    }
}

希望这能有所帮助。
