GO獲取api 接口json格式數據代碼

1.接口數據格式;

{
	"code": 0,
	"isAdmin": true,
	"data": [{
			"id": 2,
			"ip": "192.168.54.12",
			"desc": "nginx",
			"owner": "lops01"
		},
		{
			"id": 5,
			"ip": "192.168.77.237",
			"desc": "運維測試",
			"owner": "ops02"
		},
		{
			"id": 6,
			"ip": "192.168.77.82",
			"desc": "運維管理",
			"owner": "ops03"
		},
		{
			"id": 8,
			"ip": "192.168.79.230",
			"desc": "服務檯測試",
			"owner": "ops04"
		},
		{
			"id": 9,
			"ip": "192.168.79.123",
			"desc": "dev測試",
			"owner": "ops05"
		},
		{
			"id": 14,
			"ip": "192.168.47.107",
			"desc": "測試ansible封裝",
			"owner": "ops06"
		}
	],
	"columns": [{
			"name": "id",
			"alias": "惟一標識"
		},
		{
			"name": "ip",
			"alias": "受權IP地址"
		},
		{
			"name": "desc",
			"alias": "備註說明"
		},
		{
			"name": "owner",
			"alias": "使用方"
		}
	],
	"message": "success"
}

2.go 處理api json 流程;

  (1).導入json,http,io包

  (2).定義api 數據結構體;

  (3).發送http請求;

  (4).序列化json對象轉爲定義結構體;

  (5).輸出轉化json結果;

3.處理實例實際代碼;

package main

import (
   "encoding/json"
   "fmt"
   "io/ioutil"
   "net/http"
)

//定義api接口數據結構和序列化json字段
type Data struct {
   ID    int `json:"id"`
   IP    string `json:"IP"`
   DESC  string `json:"desc"`
   OWNER string `json:"owner"`
}

type CloumnsData struct {
   NAME  string `json:"name"`
   ALIAS string `json:"alias"`
}

type Employee struct {
   CODE    int `json:"code"`
   ISADMIN bool `json:"isadmin"`
   DATA    []Data `json:"data"`
   COLUMNS []CloumnsData `json:"columns"`
   MESSGAE string `json:"messgae"`
}

//發送http請求和json 序列化並打印數據結構;

func main() {
   url := "http://ops-environment.com/channel/ip/v1"
   resp, _ := http.Get(url)
   s := Employee{}
   body, _ := ioutil.ReadAll(resp.Body)
   resp.Body.Close()
   json.Unmarshal([]byte(body), &s)
   fmt.Println(fmt.Sprintf("%+v",s))

}

4.api 執行處理結果；
