package main

import "fmt"

func main() {
    var data interface{} // data 任意类型
    data = map[string]interface{}{"name":"Tom", "age":20}

    m_data := data.(map[string]interface{}) // 取出map[string]interface{}类型值
    for key, value := range m_data {
        switch v := value.(type) { // 取出对应类型进行输出
        case string:
            fmt.Println(key, v)
        case int:
            fmt.Println(key, v)
        }
