golang将map[string]接口{}解组到包含带元数据的数组的结构

type Data struct {
    Value     interface{}
    MetaData  map[string]interface{}
}

func UnmarshalData(data map[string]interface{}) []Data {
    var result []Data

    for key, value := range data {
        metaData := make(map[string]interface{})
        metaData["key"] = key

        result = append(result, Data{
            Value:     value,
            MetaData:  metaData,
        })
    }

    return result
}

func main() {
    input := map[string]interface{}{
        "key1": "value1",
        "key2": "value2",
        "key3": "value3",
    }

    output := UnmarshalData(input)

    for _, data := range output {
        fmt.Println("Key:", data.MetaData["key"])
        fmt.Println("Value:", data.Value)
        fmt.Println()
    }
}

Key: key1
Value: value1

Key: key2
Value: value2

Key: key3
Value: value3
