请求中的参数 NO_PARAM 无效请在使用 Powershell 部署 azure arm 模板时为参数 NO_PARAM 提供正确的值

Question

我正在尝试使用 powershell 和 arm 模板创建 azure 恢复服务备份保管库。对于此部署，我创建了部署模板和参数模板。我正在通过 ConvertFrom-Json 使用 powershell 编辑参数模板 json 文件，然后再次转换回 json 并使用 ConvertTo-Json 保存到模板文件。

当我执行 New-AzResourceGroupDeployment 时，出现如下奇怪的错误 请求中的参数NO_PARAM无效请为参数NO_PARAM

提供正确的值

下面是backuppolicy.deploy.json

        },
        "timeZone": "[parameters('timeZone')]"
      }
    }

}

下面是backuppolicy.parameters.json

{
  "$schema": "https://schema.management.azure.com/schemas/2019-04-01/deploymentParameters.json#",
  "contentVersion": "1.0.0.0",
  "parameters": {
    "vaultName": {
      "value": "diskencrypt"

    "policyName": {
      "value": "autoamted-policy-changed"
    },
    "scheduleRunDays": {
      "value": [

    "timeZone": {
      "value": "UTC"
    },
    "weeklyRetentionDurationCount": {
      "value": 5
    }
  }
}

下面是我用来修改json模板和触发部署的powershell代码

$days = "Monday,Tuesday,Friday"
$ScheduleBackupDays = @()
$days = $days.Split(',')
$CurrentTime = @(Get-Date -Format yyyyMMddTHHmmssZ)
foreach($day in $days){
    $ScheduleBackupDays += $day
}
$params = @{
    policyName = "autoamted-policy-changed"
    vaultName = "diskencrypt"
    scheduleRunDays = $ScheduleBackupDays
    scheduleRunTimes = $CurrentTime
    timeZone = "UTC"
    weeklyRetentionDurationCount = 5

}
$templateFile = "$PSScriptRoot\backuppolicy.deploy.json"
$paramtersfile = "$PSScriptRoot\backuppolicy.parameters.json"

$ParameterFileObject = Get-Content -Path $paramtersfile -Raw | ConvertFrom-Json

foreach($Key in $params.Keys){
    $ParameterFileObject.parameters.$Key.value = $params.Get_Item($Key)
}

$ParameterFileObject | ConvertTo-Json -Depth 100 | foreach { [System.Text.RegularExpressions.Regex]::Unescape($_) } | Set-Content -Path $paramtersfile

New-AzResourceGroupDeployment -ResourceGroupName diskencrypt -TemplateFile $templateFile -TemplateParameterFile $paramtersfile

Answer 1

这个例外有点误导。真正的问题是，ARM 无法理解参数文件中的时间戳：

"scheduleRunTimes": {
            "value": [
                "20200309T110019Z"
            ]
        }

这里有两个问题：

格式错误。 ARM 需要符合 ISO-8601 的 UTC 时间戳，其中包含所有破折号和冒号：2020-03-09T11:00:19Z
您不能在 scheduleRunTimes 中指定秒数。实际上只允许 30 分钟的步数。

从这个例子的结尾去掉 19 秒，你应该是好的：

"scheduleRunTimes": {
            "value": [
                "2020-03-09T11:00:00Z"
            ]
        }

如果您只需要当前时间，您可以像这样在 powershell 脚本中更改时间戳的格式：

$CurrentTime = @(Get-Date -Format 'yyyy-MM-dd-THH:00:00Z')

如果您需要舍入到最接近的半 n 小时，日期时间对象的情况会变得有点复杂，因为没有内置的舍入方式。

假设您要排除未来的时间戳，四舍五入到最后 30 分钟应该没问题：

$date = Get-Date
$roundedDate = $date.AddMinutes(-($date.Minute % 30))
$CurrentTime = Get-Date $roundedDate -Format 'yyyy-MM-ddTHH:mm:00Z'

Answer 2

您可以在 Parameters.json 文件中设置值 scheduleRunTimes，如下所示 format.ARM 需要符合 ISO-8601 的 UTC 时间戳，所有破折号和冒号：2020-06-26T05:30:00Z

"scheduleRunTimes": {
        "value": [
            "2020-06-26T05:30:00Z"
        ]
    },
    "dailyRetentionDurationCount": {
        "value": 104
    },
    "scheduleRunDays": {
        "value": [
            "Monday",
            "Tuesday",
            "Friday"
        ]
    },

我希望它能奏效。
