Azure Runbook 命令

Question

所以我有一个运行手册，可以在周末自动关闭和启动我的 Azure VM。然后，这会发送一封交易电子邮件，确认 VPS 已关闭/启动。

我已经如图所示设置了我的参数。为什么它在主题行中正确地说明了我的虚拟机的名称（突出显示）但在电子邮件正文（突出显示）中却出现了一个完全不同的名称，是否有原因。

逻辑会规定$VM.NAME 将是 VPS 的名称，而不是一些随机的命令行，那么这是为什么呢？它在主题行中正确显示，但不是电子邮件正文。

   param (

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

    [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
    }
}

电子邮件正文中的变量引用（例如 $VM.Name），默认情况下只会返回对象类型，其中 PowerShell 中的输出是一个特殊的管道活动，它会将内容呈现为列表或表格。为了在电子邮件中包含内容，我们必须引用属性

[string]$EmailBody = (“VMNAME IS = [{0}]” -f $VM.Name)

类似于C#中的string.format
