得到的结果

[
    {
        "id": 1,
        "pid": 0,
        "name": "学生",
        "level": 1,
        "son": [
            {
                "id": 2,
                "pid": 1,
                "name": "小敏",
                "level": 2,
                "son": []
            },
            {
                "id": 5,
                "pid": 1,
                "name": "小红",
                "level": 2,
                "son": []
            }
        ]
    },
    {
        "id": 3,
        "pid": 0,
        "name": "老师",
        "level": 1,
        "son": [
            {
