迭代对象并打印选择值

如何解决迭代对象并打印选择值

问题：我想知道如何遍历对象以打印出子网对象中每个子网的名称及其 cidr 范围。

我知道如何打印出 vnet 名称和 cidr 范围：

jq '.[] | select(.vnet) | {name: .vnet.name,cidr: .vnet.address_space[0]}'

我在网上查看，发现您可以将对象转换为数组，但我不确定如何查看该数组以打印出值： jq '.[] | to_entries | map_values(.value)'

基本上期望的输出应该是这样的：

{
    "name": "asdf1","cidr": "10....."
},{
    "name": "asdf2","cidr": "10....."
}
//...and so forth

样本输入：

        "asdf": {

            }
        },"vnet": {

            ],"enable_ddos_std": false,"name": "asdf"
        }
    }
}

解决方法

从根路径开始向下遍历并使用 to_entries 跳过不同的键名并仅使用 .value 字段

jq '.vnet_spoke_object.subnets | to_entries[].value | { name,cidr }'

或将其收集为对象数组

jq '.vnet_spoke_object.subnets | to_entries | map(.value | { name,cidr })'
