powershell 加载 json 迭代并使用键和值

问题描述

powershell 新手.. 我有 2 个 Json ，第一个是从文件中获取的，第二个是我在执行查询后转换的。如果 name 部分中的值在两个 json 中相同，我想更新第二个文件的 tag 部分中的值：

json 文件 1 使用以下内容创建和读取/加载：

$service = Get-AzResource -ResourceGroupName $sourcergname  | select-object Name,ResourceGroupName,ResourceType,Location,ResourceId,Tags
ConvertTo-Json $service | Out-File "$subscriptionid\resourceGroups\$sourcergname\Source_RG_Service_level_tags.json"
$RG_services_level_tags_json = Get-Content "$subscriptionid\resourceGroups\$sourcergname\Source_RG_Service_level_tags.json" | Out-String | ConvertFrom-Json

然后它给出：

        }
    ]

获取第二个json并使用以下内容读取：

 $service_level_tags_target = Get-AzResource -ResourceGroupName $targetrgname  | select-object Name,Tags
 ConvertTo-Json $service_level_tags_target

然后，它给出：

    [
        {
            "Name":  "mover_vnet","ResourceGroupName":  "rgmover_test-uaenorth","Location":  "uaenorth","ResourceId":  "/subscriptions/XXXXX-XXXXX-XXXXX/resourceGroups/rgmover_test-uaenorth/providers/Microsoft.Network/virtualNetworks/mover_vnet",{
            "Name":  "vmtobemoved-ip","ResourceId":  "/subscriptions/XXXXX-XXXXX-XXXXX/resourceGroups/rgmover_test-uaenorth/providers/Microsoft.Network/publicIPAddresses/vmtobemoved-ip",{
            "Name":  "vmtobemoved-nsg","ResourceId":  "/subscriptions/XXXXX-XXXXX-XXXXX/resourceGroups/rgmover_test-uaenorth/providers/Microsoft.Network/networkSecurityGroups/vmtobemoved-nsg",{
            "Name":  "vmtobemoved746","ResourceId":  "/subscriptions/XXXXX-XXXXX-XXXXX/resourceGroups/rgmover_test-uaenorth/providers/Microsoft.Network/networkInterfaces/vmtobemoved746","Tags":  null
        }
    ]

解决方法

那么，对于第一个问题，如何找到第二个 JSON 中 Name 值在第一个 JSON 的 Name 值中的项目：

首先，您可以将第一个转换为对象（就像您已经在做的那样）：

$RG_services_level_tags_json = Get-Content "$subscriptionid\resourceGroups\$sourcergname\Source_RG_Service_level_tags.json" -Raw |
ConvertFrom-Json

$service_level_tags_target = Get-AzResource -ResourceGroupName $targetrgname |
Select-Object Name,ResourceGroupName,ResourceType,Location,ResourceId,Tags

现在有很多方法可以做到这一点，您可以通过以下方式找到 $service_level_tags_target 上的项目。 注意：我更新了第二个 JSON 的名称，所以至少我们得到了 2 个匹配：

# Example 1 using -in Operator
$result = $service_level_tags_target.Where({$_.Name -in $RG_services_level_tags_json.Name})

# Example 2 using -contains Operator
$result = $service_level_tags_target.Where({$RG_services_level_tags_json.Name -contains $_.Name})

我建议您阅读 Comparison Operators 以了解哪一种最适合您的需要。例如，如果您想部分匹配，您也可以使用 -match。

这将返回 2 个匹配项：

Name              : stop-start-meetechsfrwrd/AutoStop_VM_Child
ResourceGroupName : rgmover_test-uaenorth
ResourceType      : Microsoft.Network/virtualNetworks
Location          : uaenorth
ResourceId        : /subscriptions/XXXXX-XXXXX-XXXXX/resourceGroups/rgmover_test-uaenorth/providers/Microsoft.Network/virtualNetworks/mover_vnet
Tags              : 

Name              : host-1-prd-secretenv_DataDisk_1
ResourceGroupName : rgmover_test-uaenorth
ResourceType      : Microsoft.Network/networkSecurityGroups
Location          : uaenorth
ResourceId        : /subscriptions/XXXXX-XXXXX-XXXXX/resourceGroups/rgmover_test-uaenorth/providers/Microsoft.Network/networkSecurityGroups/vmtobemoved-nsg
Tags              :

对于第二个问题，如何更新标签，您需要定义每个匹配的新标签。

foreach($resGroup in $result)
{
    $tagsaddon = # This needs to be defined here!
    Update-AzTag -ResourceId $resGroup.ResourceId -Tag $tagsaddon -Operation Merge
}
