对结构 Golang 的二维数组进行排序

map

map[string]Hit

package main

import (

  "fmt"

  "sort"

)

type Hit struct {

  Key  string  `json:"key"`

  Data []Field `json:"data"`

}

type Field struct {

  Value string `json:"value"`

}

func main() {

  var mapOfHits = getSomeHits()

  var sortedHits = sortHits(mapOfHits)

  for _, h := range sortedHits {

    fmt.Println(h.Key)

  }

}

func getSomeHits() map[string]Hit {

  return make(map[string]Hit, 0)

}

func sortHits(m map[string]Hit) []Hit {

  keys := make([]string, 0, len(m))

  sorted := make([]Hit, 0, len(m))

  for k := range m {

    keys = append(keys, k)

  }

  sort.Strings(keys)

  for _, k := range keys {

    sorted = append(sorted, m[k])

  }

  return sorted
