GO获取api 接口json格式数据代码

1.接口数据格式;

{
	"code": 0,
	"isAdmin": true,
	"data": [{
			"id": 2,
			"ip": "192.168.54.12",
			"desc": "nginx",
			"owner": "lops01"
		},
		{
			"id": 5,
			"ip": "192.168.77.237",
			"desc": "运维测试",
			"owner": "ops02"
		},
		{
			"id": 6,
			"ip": "192.168.77.82",
			"desc": "运维管理",
			"owner": "ops03"
		},
		{
			"id": 8,
			"ip": "192.168.79.230",
			"desc": "服务台测试",
			"owner": "ops04"
		},
		{
			"id": 9,
			"ip": "192.168.79.123",
			"desc": "dev测试",
			"owner": "ops05"
		},
		{
			"id": 14,
			"ip": "192.168.47.107",
			"desc": "测试ansible封装",
			"owner": "ops06"
		}
	],
	"columns": [{
			"name": "id",
			"alias": "唯一标识"
		},
		{
			"name": "ip",
			"alias": "授权IP地址"
		},
		{
			"name": "desc",
			"alias": "备注说明"
		},
		{
			"name": "owner",
			"alias": "使用方"
		}
	],
	"message": "success"
}

2.go 处理api json 流程;

(1).导入json,http,io包

(2).定义api 数据结构体;

(3).发送http请求;

(4).序列化json对象转为定义结构体;

(5).输出转化json结果;

3.处理实例实际代码;

package main

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

//定义api接口数据结构和序列化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"`
}

//发送http请求和json 序列化并打印数据结构;

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 执行处理结果；
