数据格式转换提取

老师，原数据如下：

{
    "visible": false,
    "op": "ok",
    "configId": "1532989921256673280",
    "originList": [
        {
            "title": "小明",
            "icon": {
                "type": {},
                "key": null,
                "ref": null,
                "props": {},
                "_owner": null,
                "_store": {}
            },
            "key": "{\"corpId\":\"wwe094a1deac86058c\",\"id\":\"18888888888\",\"type\":2,\"deptId\":\"1\"}",
            "selectable": false,
            "checkable": true,
            "isLeaf": true,
            "id": "13479948921",
            "expanded": false,
            "selected": false,
            "checked": false,
            "loaded": false,
            "loading": false,
            "halfChecked": false,
            "dragOver": false,
            "dragOverGapTop": false,
            "dragOverGapBottom": false,
            "pos": "0-0-45",
            "active": false
        },
        {
            "title": "小红",
            "icon": {
                "type": {},
                "key": null,
                "ref": null,
                "props": {},
                "_owner": null,
                "_store": {}
            },
            "key": "{\"corpId\":\"wwe094a1deac86058c\",\"id\":\"18888888889\",\"type\":2,\"deptId\":\"1\"}",
            "selectable": false,
            "checkable": true,
            "isLeaf": true,
            "id": "13479948921",
            "expanded": false,
            "selected": false,
            "checked": false,
            "loaded": false,
            "loading": false,
            "halfChecked": false,
            "dragOver": false,
            "dragOverGapTop": false,
            "dragOverGapBottom": false,
            "pos": "0-0-45",
            "active": false
        }
    ]
}

该怎么把上面数据提取成如下格式呢：

（对照关系：

corpId对应上面originList中的key里面的corpId；

id对应上面originList中的key里面的id；）

[
    [
        {
            "corpId": "wwe094a1deac86058c",
            "id": "18888888888"
        },
        {
            "corpId": "wwe094a1deac86058c",
            "id": "18888888889"
        }
    ]
]

• 特别注意：数组长度是非固定的，比如，数据目前示例为只有两个数据，实际上数量是不固定的，是根据提取前的数据长度来决定，同时，提取前的数据长度也是非固定的，要看接口返回来的数量是多少来决定。
