go语言中对map排序

package main

import (
    "sort"
    "fmt"
)

func main(){
    user := make(map[string]string)
    user["name"] = "小红"
    user["age"] = "18"
    user["sex"] = "女"

    var keys []string
    for k := range user {
        keys = append(keys, k)
    }
    //按字典升序排列
    sort.Strings(keys)
    //按字典降序排列
    //sort.Sort(sort.Reverse(sort.StringSlice(keys)))

    for _, k := range keys {
        fmt.Println("Key:", k, "Value:", user[k])
    }
}

输出

Key: age Value: 18
Key: name Value: 小红
Key: sex Value: 女

func sortByColumn(column string, data []RespUserShowAgentInfo) {
    sort.Slice(data, func(i, j int) bool {
        switch column {
        case "appname":
            return data[i].Appname < data[j].Appname
        default:
            return data[i].Appname < data[j].Appname
        }
    })
}
