paginate返回的数据，在API中并不适用，比如first_page_url这种，如何把这个过滤掉？

{
        "current_page": 2,
        "data": [
            {
                "store_group_id": 2,
                "channel": {
                    "id": 2,
                    "channel_name": "石家庄金平区"
                }
            },
            {
                "store_group_id": 2,
                "channel": {
                    "id": 2,
                    "channel_name": "石家庄金平区"
                }
            }
        ],
        "first_page_url": "http://pinkr.work/Crm/Store/GetStoresByChannel?page=1",
        "from": 3,
        "last_page": 3,
        "last_page_url": "http://pinkr.work/Crm/Store/GetStoresByChannel?page=3",
        "next_page_url": "http://pinkr.work/Crm/Store/GetStoresByChannel?page=3",
        "path": "http://pinkr.work/Crm/Store/GetStoresByChannel",
        "per_page": "2",
        "prev_page_url": "http://pinkr.work/Crm/Store/GetStoresByChannel?page=1",
        "to": 4,
        "total": 5
    }

这里面中的first_page_url、last_page_url、next_page_url、prev_page_url、path 并不需要，怎样把这些字段过滤掉？
