没有什么它使用现有的系统封装，它相当简单的go

package main

import (

"encoding/json"

"fmt"

"net/http"

)

func main() {

var data struct {

Items []struct {

Name string

Count int

Is_required bool

Is_moderator_only bool

Has_synonyms bool

}

}

r, _ := http.Get("https://api.stackexchange.com/2.2/tags?page=1&pagesize=100&order=desc&sort=popular&site=stackoverflow")

defer r.Body.Close()

dec := json.NewDecoder(r.Body)

dec.Decode(&data)

for _, item := range data.Items {

fmt.Printf("%s = %d\n", item.Name, item.Count)

}

}
