Azure Runbook命令

Question

因此，我有一本運行手冊，可以在周末自動關閉和啟動我的Azure VM。 然后，這會發送交易電子郵件，確認已關閉/啟動了VPS。

我已經按照說明設置了參數。 是否有理由說明為什么它在主題行中正確指出了我的虛擬機的名稱（突出顯示），但是在電子郵件正文（突出顯示）中卻使用了完全不同的名稱。

邏輯要求$VM.NAME是VPS的名稱，而不是某些隨機命令行，所以這是為什么呢？ 它正確顯示在主題行中，但未正確顯示在電子郵件正文中。

   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
    }
}

電子郵件正文中的變量引用（例如$ VM.Name），默認情況下將僅返回對象類型， 而PowerShell中的輸出是特殊的管道活動 ，它將以列表或表格的形式呈現內容。 為了在電子郵件中包含內容， 我們必須引用屬性

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

與C# string.format相似
