json - 删除多个符合条件的对象

问题描述

我有这个 JSON 文件：

{
    "uuid": "ce651ed3-78b9-49a0-9d00-9bfaf33bb12c",
    "mp_router_id": "bbbf9a22-5fde-48e2-980f-a6c58d7f941a",

        },
        {
            "uuid": "8fd5f7a5-5906-40b7-b8c4-877882896ca8",
            "urpf-mode": "NONE",

            "type": "backplane",
            "name": "bp-sr0-port"
        },
        {
            "uuid": "65f526d1-621c-4f5b-a7e6-7d06278e0226",

            "type": "uplink",

        },
        {
            "uuid": "36ccfb0d-45ad-5242-9e0f-2898de2c82db",
            "lrouter": "ce651ed3-78b9-49a0-9d00-9bfaf33bb12c",

            "type": "blackhole",
            "name": ""
        }
    ],
    "vdr_id": 16,
    "name": "SR-t1"
}

我需要的输出是：

{
            "uuid": "ce651ed3-78b9-49a0-9d00-9bfaf33bb12c",
            "type": "TLR-SR",
            "ports": [
                {
                    "uuid": "8fd5f7a5-5906-40b7-b8c4-877882896ca8",
                    "admin_up": false,
                    "ips": [
                        "169.254.0.2/28"
                    ],
                    "op_state_up": false,
                    "type": "backplane",
                    "name": "bp-sr0-port"
                },
                {
                    "uuid": "65f526d1-621c-4f5b-a7e6-7d06278e0226",
                    "admin_up": false,
                    "ips": [
                        "100.64.208.1/31"
                    ],
                    "op_state_up": false,
                    "type": "uplink",
                    "name": "LinkedPort_t0-uplink"
                },
            ],
            name": "SR-t1"
        }

我不想显示具有以下类型的元素。如果.ports[].type == "blackhole"或"cpu-port"或"loopback"

我能够获取端口数组中的所有内容，但找不到排除我希望排除的元素的方法。JQ 可以做到这一点，还是我错过了一些非常基本的东西？

标签： jsonjq

要消除您不想要的端口，您可能会找到使用map(select(...))成语直观的这些等效替代方案之一：

.ports |= map( if (.type | . == "blackhole" or . == "cpu-port" or . == "loopback") then empty else . end)

.ports |= map( if .type | IN("blackhole", "cpu-port", "loopback") then empty else . end)

.ports |= map( select( .type | IN("blackhole", "cpu-port", "loopback") | not ) )

要选择感兴趣的键值对，可以使用{foo, bar}简写为{"foo":.foo, "bar":.bar}
