运行 天蓝色自动化中的 powershell 代码时失败

Failed when running powershell code in azure automation

我设置了 azure 策略 添加两个标签,即 CreatedTimeTypeCreatedTime的值为utcNow(),默认格式为'yyyy-MM-ddTHH:mm:ss.fffffffZ'.

我的目标是删除所有 Typeprivatecreated time 长于 的资源]2 天 运行ning powershell azure automation.

中的代码]

我已经在 power shell locally 中完成了,但是当我 运行 automation 中的代码时,它失败了。我将 post 下面的代码和错误页面。

谁能告诉我我的代码有什么问题?或者我错过了什么?

这是我在 Azure 自动化中的代码:

   $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
    }
}

    $AllRes = (get-AzureRMResource).ResourceId
    $TimeOutDays=2
    foreach ($Res in $AllRes){
    $Resource = Get-AzureRMResource -ResourceId $Res
    $Tags=$Resource.Tags
    $TypeInTags=$Tags['Type']
    $CreatedTimeInTags=$Tags['CreatedTime']
try{
    $CreatedTime=[Datetime]::ParseExact($CreatedTimeInTags, 'MM/dd/yyyy HH:mm:ss', $null)
}
catch{
    $CreatedTime=[Datetime]::ParseExact($CreatedTimeInTags, 'yyyy-MM-ddTHH:mm:ss.fffffffZ', $null)
}
finally
{
    $CreatedTime
}
    $daypan=((get-date)-$CreatedTime).Days
    if($TypeInTags -eq 'private')
    {
    if($daypan -gt $TimeOutDays)
        {
            $daypan
            Remove-AzureRMResource -ResourceId $Res -Force
        }
    }
}

这是错误页面: 暂停

对于$Tags['CreatedTime']的类型,我是这样测试的:$Tags['CreatedTime'].GetType().FullName.

既然你说 CreatedTime 的值是 utcNow(),那么这个值已经是一个 DateTime 对象,你不应该把它当作字符串。 (你认为它是一个字符串,因为当你把它写到控制台时,它会显示它的ToString()表示)

简单做

$CreatedTime=$Tags['CreatedTime']

您可以使用 write-host $Tags['CreatedTime'].GetType().FullName

进行测试

有两点不对。

1.Didn没有指定我需要的资源。

详情:

这就是错误消息的原因:Can not index to a null array. 我遍历了订阅中的整个资源,但是 在我设置策略之前创建的资源没有名为 "CreatedTime" or "Type", 所以当我 运行 $Tags=$Resource.Tags, 它 说 Can not index to a null array.

我的解决方案:

除了 $AllRes = (get-AzureRMResource).ResourceId 之外,还 $AllRes = (get-AzResource -TagName "CreatedTime").ResourceId。 我发现 AzureRM 模块没有 将 -TagName 识别为变量,因此我导入 Az 模块并 将每个 AzureRM 模块更改为 Az 模块。

2.Confused 与 utcNow().

详情:

正如我所说,使用 utcNow() 函数我得到一个默认的 DateTime 对象 格式 'yyyy-MM-ddTHH:mm:ss.fffffffZ',经过大量测试, 我发现一些特殊资源,如 application insight 的标签值是 未使用 'yyyy-MM-ddTHH:mm:ss.fffffffZ' 格式化,当我调用 它,就到了一个字符串。

我的解决方案:

所以当我使用它时与 get-date 相比,我 需要做两件事:

(1)将字符串改为DateTime对象;

(2)使用try-catch满足两种格式
