如何在Golang中的嵌套JSON对象中解析嵌套数组?

I have a JSON:

{
    "data": [
        {
            "id": 1,
            "values": [
                [
                    {
                        "id": "11",
                        "keys": [
                            {
                                "id": "111"
                            }
                        ]
                    }
                ]
            ]
        }
    ]
}

I want to parse "values" and "keys" into structs, but I don't known what type should i use in "Data"?:

type Value struct {
    Id   string `json:"id"`
    Keys []Key  `json:"keys"`
}
type Key struct {
    Id string `json:"id"`
}
type Result struct {
    Data []Data `json:"data"`
}
type Data struct {
    Id     int      `json:"id"`
    Values []???? `json:"values"`
}

I would be grateful for any help. Thanks.

    If you look carefully at your json. you have an array in an array...

    ...
        "values": [
                        [...
    

    If this is intended then the type of values is:

    [][]Value
    

    to represent the two arrays, else remove the array nesting and it becomes:

    []Value
