powershell - 如何从Powershell脚本中的列表中查询

Question

我有json格式的响应:

{
    "properties": {
        "basic": {
            "nodes_table": [
                {
                    "node": "node1.prod.local:80",
                    "state": "active",
                    "weight": 1
                },
                {
                    "node": "node2.prod.local:80",
                    "state": "disabled",
                    "weight": 1
                },
                {
                    "node": "node3.prod.local:80",
                    "state": "disabled",
                    "weight": 1
                },
                {
                    "node": "node4.prod.local:80",
                    "state": "disabled",
                    "weight": 1
                },
                {
                    "node": "node5.prod.local:80",
                    "state": "active",
                    "weight": 1
                }
            ]
        }
    }
}

我要在Powershell脚本中尝试执行的操作是找出是否可以在node_table中使用给定的节点并获取其状态。例如:

$nodes_table_hostnames = $GetNodesResponse.properties.basic.nodes_table.node
$nodes_table_status = $GetNodesResponse.properties.basic.nodes_table.state

if($nodes_table_hostnames -contains "node1.prod.local:80" -and $nodes_table_status -eq "active")
    {
        Write-Output  "Node matches and is Active"
    }

问题:
我在获取“特定”节点的状态时遇到问题，因此我想检查表中是否存在“给定”节点，并且该节点的状态为 Activity /禁用。我将如何在脚本中完成此任务？

Answer 1

$Active = $GetNodesResponse.properties.basic.nodes_table |
            Where {$_.Node -eq "node1.prod.local:80" -and $_.state -eq "active"}
If ($Active) {Write-Output  "Node matches and is Active"}
